8 integrated prevention and control measures of diseases and insect pests in Anthurium andraeanum leaves

In addition to the above-mentioned chemical prevention and control of Anthurium andraeanum leaf flower diseases and insect pests, we should also pay attention to the comprehensive control from the following aspects.

8.1 strengthen the temperature, humidity and light control of the greenhouse.

The optimum growth temperature of Anthurium andraeanum is 20 ℃ ~ 28 ℃, the highest temperature should not exceed 35 ℃, and the freezing injury may occur when the lowest temperature is lower than 10 ℃. The optimum air relative humidity is 75%-80%, not less than 50%.

Keeping high air humidity in the cultivation environment is the key to the successful cultivation of Anthurium andraeanum. Temperature and humidity should be controlled throughout the year, and plants should be kept dry. It should be cultivated under proper shade throughout the year, and should be properly shaded in spring, summer and autumn, especially in summer.

8.2 strengthen the management of water and fertilizer

Irrigation water should be disinfected as much as possible, and drip irrigation should be used in combination with nutrient solution. At the same time, pay attention to the leaf surface of non-sticky water, in order to reduce the growth of bacteria. Reduce the amount of ammonium nitrate during fertilization, which can reduce the nutrition of bacterial growth and development. The pH of culture medium should be kept at about 5.5.

8.3 strict management of planting area

Strict quarantine and the use of plants or tissues carrying pathogenic microorganisms is prohibited. In order to strengthen sanitary measures, set up a disinfection pool at the entrance of the planting area, we must wash hands with disinfectant, strengthen the disinfection management of working tools, disinfect clothes and shoes, etc., and at the same time strengthen personnel management. minimize personnel replacement and mobility. The plant, tissue and matrix of diseases and insect pests should be found and removed in time, and then put into airtight plastic bags and taken out of the park for destruction.

8.4 promote biological control and timely chemical control

Try to choose bionic agents such as urea and antibiotic pesticides to avoid the use of chemical pesticides. Anthurium andraeanum is relatively sensitive to copper preparations and some organophosphorus pesticides, so chemical pesticides with strong pollution and sensitivity to plants should be avoided as far as possible in the selection of chemical control.

The above are the prevention and control measures of common diseases and insect pests of Anthurium andraeanum. Friends of florists come and learn. You are welcome to put forward more experiences and methods to communicate with other florists!

What are the common pests of family farmed flowers? Control methods of common insect pests in flowers

The common pests of family cultured flowers are aphids, mosquitoes and flies (bacteria and flies) and whitefly, which not only adversely affect the ornamental of flowers, but also seriously threaten the healthy growth of flowers. There are two main methods for the prevention and control of flower pests, one is killing, which is mainly aimed at the pests with large individuals and a small number, and the other is insecticide, which is mainly aimed at the pests of mouthparts, such as beetles, pteroptera larvae and so on.

I. aphids

Harmful characters: aphids are a kind of bluish yellow insects, often concentrated on new shoots or buds such as rose, pomegranate and chrysanthemum, sucking liquid juice with mouthparts, resulting in curling and atrophy of tender leaves, seriously affecting growth and flowering, curling and withering plant leaves, producing galls and spreading virus disease.

Prevention and control methods: continuously smear leaves with tobacco water (50 times liquid) and soapy water for several times; spray with 25% fish rattan essence 800ml 1000 times solution, 40% chlorinated dimethoate 2000 times solution, 3% natural pyrethroid 1000 times liquid and deltamethrin 2000000 times liquid and so on.

2. Red spider

Harmful characters: mainly harmful to rhododendron, rose, a bunch of red, begonia, cactus, dragon cypress, etc., will suck juice with piercing mouthparts to harm the plant, resulting in small yellow-white spots on the leaves, and even scorch or fall off the leaves.

Control methods: remove weeds in the basin, eliminate overwintering eggs, improve ventilation conditions and reduce temperature; acaricides can be used for chemical control, such as butyl ether urea, abamectin, pyridaben, methotrexate, amitraz, dicofol or omethoate 100 times solution alternately sprayed on the leaves of red spiders at the initial stage of occurrence.

Mosquitoes and flies (bacteria and flies)

Harmful flowers: it is common to grow seedlings with potted flowers or grass flowers, such as poinsettia, cyclamen and pansy.

Control methods: the use of Huifu, Huijian, avermectin and other agents, through root irrigation to prevent and control mosquitoes and flies larvae.

4. Thrips

It mainly harms many kinds of flowers, such as Anthurium andraeanum, cyclamen, rose, carnation, Platycodon grandiflorum and so on. Thrips often file and suck juice at the back of tender leaves and floral organs, making the injured leaves curl, yellow, brittle and shedding.

Prevention and control methods: physical, chemical and biological methods can be used for comprehensive control; chemical control uses Huijian, lice acaroid urea, Huijian + kungfu, avermectin, spinosad and other chemical spray control.

5. Scale insects

Harmful characters: the main species of scale insects are powdery insects, red wax scale insects, blow cotton shell insects and so on, which are mainly parasitic on the young stems and leaves of plants and insert plant tissues to absorb sap with prickle mouthparts, which is one of the common pests in indoor foliage plants.

Prevention and control methods: manual control: remove the worm body with a brush and then rinse it with water; chemical control: in the peak incubation period of nymphs whose waxy shell has not yet been formed on the surface of the insect body, spray control is carried out with 1000 times of isocarbophos, 1500-2000 times of fenvalerate and 800 times of omethoate.

6. Whitefly

Harmful characters: whitefly is widely distributed and harms many kinds of flowers. the body of whitefly is small and white, and the mouthparts of adults and larvae insert juice from the back of the leaves to make the leaves withered and yellow, while excreting honeydew on the leaves and causing soot disease.

Control method: spray 2.5% deltamethrin, 20% permethrin 1500mur2000 times and pyrethroid and other pesticides to control nymphs, adults and eggs, once every 7 days, 3-4 times in a row.

7. Underground pests such as nematodes and grubs

Harmful characters: mainly bite the roots and tender stems of plants underground, resulting in root and stem rot and plant death.

Control methods: disinfect the soil with steam or medicament, trap and kill trichlorfon with food, irrigate plants with 1000 times liquid of trichlorfon, and kill manually.

8. Snails

Harmful characters: snails mainly harm plant leaves, tender stems and roots, making plant branches and leaves incomplete, affecting plant growth and ornamental, and even leading to planting death in serious cases.

Prevention and control methods: sprinkle with trichlorfon food in the snail's regular activity area; spray around the plant with trichlorfon and deltamethrin 1500 / 2000 times; and kill the snail with 8% Mianhuoling granule around the root agent.

What are the methods of flower pest control?

With the improvement of people's living standards, the construction of green families is more and more favored by people, and flowers are planted more and more widely. However, there are often pests in family flower cultivation, which not only affect the healthy growth of flowers and trees, but also hinder viewing. How to prevent and control diseases and insect pests is a problem often discussed by friends who love to grow flowers.

Generally speaking, the environmental conditions suitable for the growth and survival of family farmed flowers also create conditions for the occurrence and prevalence of many diseases and insect pests. The occurrence of diseases and insect pests depends on temperature sooner or later, and the severity of diseases and insect pests mainly depends on humidity in addition to the influence of temperature. In order to prevent and control diseases and insect pests, we should grasp the principle of "giving priority to prevention", strengthen management, and pay attention to ventilation, light transmission, watering, fertilization and other maintenance work. Make flowers and trees grow and thrive and enhance their ability to resist diseases and insect pests. Once diseases and insect pests are found, measures should be taken as soon as possible to achieve "early treatment, small treatment, and treatment" to prevent spread. When necessary, use chemicals to control, inhibit and kill diseases and insect pests, eliminate the threat of diseases and insect pests, and ensure the healthy growth of flowers.

The common pests of family flowers are aphids, red spiders, mosquitoes and flies (bacteria and flies), thrips, shell insects, whitefly, etc., and diseases include anthracnose, brown spot, soft rot, root rot (black stem disease), powdery mildew and so on.

Generally speaking, there are two main methods of flower pest control: culling and insecticide.

1. Culling

Pests with large individuals and small numbers, such as beetles, scale insects and larvae of Coleoptera, are caught and killed as soon as they are found.

2. Drug killing

That is, the toxicity of drugs is used to kill pests. Different types of drugs are sprayed according to the mouthparts of pests. Pests of mouthparts, such as beetles and pteroptera larvae, can be sprayed with stomach poisons and pesticides to kill them. Pests of piercing mouthparts, such as aphids, scale insects, whiteflies, etc., can be sprayed with internal inhalant pesticides to kill them. Contact pesticides can be sprayed on soil pests, such as beetle larvae, grubs, golden needle worms, nematodes, etc.

Here's a summary of some of the most common pest control methods:

Common insect pests and harmful small animals and their control

I. aphids

Harmful traits: aphids are bluish yellow insects that harm almost all flowers and trees. Between spring and summer, it is often concentrated on new shoots or buds such as rose, pomegranate, oleander and chrysanthemum, sucking liquid juice with mouthparts, causing tender leaves to curl and atrophy, seriously affecting not only growth and flowering, but also plant leaves curling and withering, producing galls and spreading virus disease. When aphids suck juice, they will discharge a sticky liquid called honeydew to stick to the leaves, attracting ants and causing mildew at the same time. Aphids can produce 20 million 30 generations a year, and eggs can survive the winter.

Harm to flowers: a wide range of hosts, mainly harmful to rose, pomegranate, oleander, chrysanthemum, carnation, chrysanthemum, cyclamen, hibiscus, bauhinia, poinsettia, melon and leaf chrysanthemum and other flowers.

Prevention and treatment: when a small amount occurs, it can be extruded with something, and then rinsed with water; it can also be smeared with tobacco water (50 times liquid) and soapy water for several times. Chemical control can be used to control aphids by spraying 25% fish rattan essence 800ml 1000 times, 40% chloromethoate 2000 times, 3% natural pyrethrum 1000 times and deltamethrin 2000000 times, all of which can kill aphids very well, and the effect is satisfactory.

2. Red spider

Harmful traits: red spider body is small, red, it is difficult to see with the naked eye. Often clustered on the back of the leaves of flowers and plants, sucking juices with prick mouthparts to harm the plants, making the leaves yellow-white spots, and then gray-white, so that the leaves scorched or fell off. It can occur for more than 10 generations a year, often growing in an environment of high temperature and low humidity. Harmful flowers: widely distributed, miscellaneous eating habits, almost all ornamental plants such as herbs, woody plants, cut flowers, potted flowers and so on may be harmed. Often harm azaleas, roses, a string of red, begonia and real cypress, kumquat, generations, cactus, cypress and so on, of which azaleas and cypresses suffer the most. It usually occurs more often in high-temperature and dry environments (such as indoor sunny windows, etc.) and propagates quickly.

Control methods: remove weeds in the basin and eliminate overwintering eggs. When a small amount occurs, the seriously infected leaves can be removed and washed with water; improve ventilation conditions, reduce the temperature; often spray more water around the plant to increase air humidity. Acaricides, such as butyl ether urea, avermectin, pyridaben, methamphetamine, amitraz, dicofol or omethoate, were alternately sprayed on the leaves of red spiders at the initial stage of the occurrence of red spiders, once every other week.

Mosquitoes and flies (bacteria and flies)

Harmful characters: the main food of larvae is plant pathogenic saprophytic fungi, and the result of feeding by larvae leads to the infection of plant pathogens through roots. Mosquito and fly larvae feeding on flower roots reduces the ability of flowers and plants to absorb water and nutrients, which makes the plants grow slowly and dwarf. In addition, mosquito and fly feeding can also cause flower Pythium, blight and black root rot.

Harmful flowers: it is common to grow seedlings with potted flowers or grass flowers, such as poinsettia, cyclamen and pansy.

Prevention and control methods: chemical control, the use of Huifu (Citation), Huijian, avermectin and other agents through root irrigation to prevent and control mosquitoes and flies larvae.

4. Thrips

Harmful characters: thrips black or brown, common flower thrips, tobacco thrips, yellow thrips and western flower thrips, serious damage period is spring and summer. Thrips often file juice harm at the back of tender leaves and floral organs, so that the injured leaves curl, the mesophyll appears yellow file spots, and the injured leaves turn yellow, brittle and fall off. Sometimes there will be gray-white or brown spots on the petals, or discoloration, discoloration and other phenomena that affect the quality of flowering.

Harmful flowers: anthurium, cyclamen, roses, carnations, Platycodon grandiflorum and other flowers.

Control method: because it can produce resistance to many insecticides, physical, chemical and biological methods are used in production. Chemical control uses Huijian, lice acaridourea, Huijian + kungfu, avermectin, doxorubicin and other agents to alternate foliar spray for 5 to 7 days.

5. Scale insects

Harmful characters: there are many kinds, such as powder worm, red wax shell worm, blow cotton shell worm, brown round shell worm and so on. It is one of the common pests in indoor foliage plants, especially in woody foliage plants and coniferous plants. It is mainly parasitic on the young stems and leaves of plants and uses piercing mouthparts to insert plant tissues to absorb juice. The wound is easily infected with diseases and can induce soot disease. Its fecundity is very strong, and it can reproduce many generations a year when the environmental conditions are suitable, so it can cause damage every year in areas with higher temperatures.

Prevention and control methods: when a small amount occurs, it is usually controlled manually, that is, remove the worm with a brush and rinse it with water. Chemical control is best carried out during the peak incubation period of nymphs whose waxy shell has not yet been formed on the surface of the insect body, so that it is easier to kill the insect body and can improve the control effect. The medicament can choose 1000 times liquid of isocarbophos, 1500-2000 times of fenvalerate, 800 times of omethoate and 1000 times of omethoate, spraying 2 or 3 times every other week. If the occurrence is more serious, it is necessary to use a combination of artificial and chemical prevention and control methods, that is, first use a brush to remove the medium, and then spray with the above-mentioned agents, so that the effect is more ideal.

6. Whitefly

Harmful characters: widely distributed, harmful to a variety of flowers, indoor foliage plants often occur in greenhouses or plastic greenhouses, especially in dry environment. The insect body is small and white, and the mouthparts of adults and larvae are inserted from the back of the leaves to absorb the juice, making the leaves withered and yellow. The wound is prone to brown rot, which can lead to plant death in severe cases. At the same time, Honeydew is excreted on the leaves and causes soot disease.

Prevention and control methods: 2.5% deltamethrin, 20% fenvalerate 1500Mel 2000 times solution and pyrethroid and other pesticides can be sprayed to control nymphs, adults and eggs, usually once a week for 3 consecutive 4 times.

7. Underground pests such as nematodes and grubs

Harmful characters: this kind of pests mainly bite the roots and tender stems of plants in the ground, or damage the root corms, resulting in root and stem rot and plant death.

Control methods: disinfect the soil with steam or medicament to put an end to nematodes and other root causes; mix food with trichlorfon and sprinkle it or bury it next to seedlings for trapping; irrigate plants with 1000 times of trichlorfon solution; kill manually.

8. Snails

Harmful traits: small terrestrial molluscs, mostly living in a humid environment for years. Like Yin dampness, afraid of dryness and strong light. It often harms the leaves, tender stems and roots of perennial herbaceous foliage plants, makes the branches and leaves of the plant incomplete, affects the growth and ornamental of the plant, or makes the plant die.

Prevention and control methods: you can scatter trichlorfon and trichlorfon food in its regular activity place; spray around the plant with trichlorfon and deltamethrin 1500 / 2000 times; spread 8% Mianhuoling granule on the soil around the root agent to kill snails. In addition, pay attention to indoor cleanliness, timely removal of withered branches and leaves, reduce its living space.

Here are the general methods of pre-prevention and control of flower diseases and insect pests:

The main results are as follows: 1. Keeping the environmental hygiene of flower cultivation can reduce the harm.

2, protect the plant, do not break the skin, be injured, beware of germs invasion.

3. Pre-disinfection of culture can kill germs and pests.

4. Strengthen daily management, keep proper water and fertilizer, smooth air, suitable temperature and daylighting, so as to make the plant grow healthily and control the breeding and spread of diseases and insect pests.

5. Outdoor overwintering flowers, spray or smear stone sulfur mixture after falling leaves, spray Bordeaux liquid 1-3 times in early spring and before flower bud germination, wither and control diseases and insect pests. The seedlings sown with blight appeared scalded near the surface at first, then softened and fell to the ground and died. Sprinkling plant ash or irrigating ammonium solution on the surface of basin soil can sterilize and protect seedlings. There are orange or yellow spots on the leaves of carnation and Rosaceae flowers at the initial stage, yellow powder on the back at the later stage, brown spots on the peel before the blossom and decline of the leaves, and then spray 1-3 times or carbendazim mixture or carbendazim powdery mildew on both sides of the leaves of Rosaceae and Compositae flowers to reduce humidity. Spraying Bordeaux solution with Dysenamine or carbendazim solution to prevent the appearance of white spots on the leaves of herbaceous flowers with unconspicuous outline at the initial stage, and spraying Bordeaux solution with white fine hairs for 1-3 times in the later stage could prevent water-immersed spots on the leaf surface of herbaceous flowers with soft rot, and droop Bordeaux solution behind the face. Brown streak orchid flowers appear brown sunken spots on the leaves, dry coke leaves pay attention to shade and improve air humidity, the same amount of Bordeaux liquid black rust Compositae flowers appear yellow-green spots in the early stage, fly yellow powder after rupture, and finally turn black patches to strengthen drainage, full sunshine, strengthen ventilation and spray Bordeaux liquid. Soot disease perennial evergreen flowers appear dark brown coal stain on the leaf surface, and then gradually expand to form a black soot-like mildew layer to spray Bordeaux solution, or use 5% alcohol to detect the coal pollution.

Now let's introduce several common methods for the prevention and control of flower diseases and insect pests.

1. Tobacco has the effects of stomach poison contact and fumigation because it can cause nerve paralysis and poisoning of pests. The use of tobacco leaf stalks or leftover cigarette butts (to remove the filter tip) is to soak in water 50 times and 60 times for one day and night, and then spray to control aphids, cotton red spiders and newly hatched shell insects.

2. The wind oil essence diluted 600 times to 800 times can control aphids, scale insects, moths and butterflies larvae, 400 times 600 times liquid can control cotton red spiders.

3. Mosquito spray can kill whitefly pests after hanging the ignited mosquito on the flowers and plants and filling the seam with plastic film for about 10 minutes.

4. Soapy water take general soapy water or use the rest of the soapy head flakes to be hydrated by hot hydration according to the proportion of 160 and cooled with water. Spraying can control aphids and cotton red spiders if soaking cigarette butts (removing cigarette ash) in soapy water can improve the control of aphids and red spiders. The detergent solution can kill aphids, scale insects, cotton red spiders, green thorn moths, pink butterflies, whitefly and other plants with tuberous roots (such as peony, dahlia) or bulbs (such as lilies, Lycoris radiata). Flowers and plants with fleshy roots are vulnerable to nematode risk, and flowers and plants with fleshy roots are vulnerable to nematode risk. 1000 times diluted detergent solution can also be used around the plant roots.

After dissolving soap and hot water at 150%, spraying soap can clog the respiratory organs of pests to their extinction to aphids and scale insects. Effective tobacco liquid containing nicotine has a strong contact killing effect on aphids, cotton red spiders, ants and so on. It also has fumigation and stomach toxicity. Take 20 grams of tobacco or cut tobacco and soak 500 grams of water for 24 hours, then add 2% soap water 500 grams to spray on the leaves infected with insects. The filtrate can also be sprayed directly on the basin soil and around the basin bottom without soapy water to kill pests in the soil.

Garlic solution for powdery mildew and black spot disease, 30 grams of garlic, 500 grams of water, 500 grams of water.

After 50 grams of green onions were pounded into mud and soaked in water for 12 hours, filtrate was sprayed with filtrate for 3 times a day for 4 days to control software pests such as aphids and powdery mildew.

The new ginger juice can be mashed and soaked in water 20 times for 12 hours, and then sprayed with filtrate can control leaf spot, coal pollution, rot, black spot, aphids, cotton red spiders and leafminers.

The citrus peel liquid was soaked in 50 grams of citrus peel and 500 grams of water for 24 hours. after filtration, the filtrate was sprayed to control aphids, cotton red spiders and leaf worms, and poured into the soil to control nematodes. In addition, one part of citrus seeds can be soaked in 5 parts of water for 4-5 days, and then the ovules of flowers and plants can be soaked in this solution for 10 minutes to control many kinds of pests. Balsam pear leaf liquid will mash balsam pear leaves 100g, 200g, add water and the same amount of lime to mix evenly, irrigate the roots of plant seedlings, and control Dishan king. Tomato leaf liquid 50 grams of fresh tomato leaves mashed and 150 grams of water soaked for 6 hours, then sprayed with filtrate to control aphids, cotton red spiders and other flies.

Take 50 grams of chili pepper and boil it with 10 times water for 20 minutes, then filter and spray the filtrate to control aphids, cotton red spiders, stink bugs and other pests to control soil silkworms.

Castor leaf powder dried castor leaves and stems, ground them into powder and applied them to the soil to control grubs.

Oleander solution 50 grams of oleander branches and leaves and 100 grams of water boiled for 20 minutes to remove the residue for 30 minutes to spray to control aphids and whitefly poured into the soil to control nematodes but pay attention to the toxicity of oleander and beware of human and animal feeding.

Rice vinegar containing rich organic acids has a good inhibitory effect on bacteria. Spraying 150 × 200 times diluted rice vinegar on the leaf surface for 3 times every 7 days can control powdery mildew, black spot, downy mildew and so on.

Take 5 grams of baking soda solution, also known as sodium bicarbonate, first dissolve it with a small amount of alcohol, and then add about 1000 grams of water to form a 0.5% concentration solution to spray plants to control powdery mildew.

Mosquitoes, mosquitoes, mosquitoes,

Potassium permanganate solution, commonly known as gray manganese oxygen potassium permanganate solution, can control powdery mildew of flowers and herbs. spray 0.1% 0.2% solution for 7 days and spray 2 times for 3 times for more than 92%. Do not touch potassium permanganate solids directly.
