II. Disease and pest control of saffron / 3 insect pests 2 diseases

1. Heart-drilling insect pest

The heart-drilling bug is a kind of pest that many plants will face. this kind of pest mostly occurs in autumn, which mainly harms the tidbits of saffron. Once the tidbits are threatened by this pest, they will yellowing. Not coming out for a long time will lead to the phenomenon of flowers withering and dying gradually.

Control methods: when this kind of pest occurs, it is best to deal with it as soon as possible, because the longer the delay, the greater the harm to the flowers. For the prevention and control of this pest, we can generally use methamidophos to spray saffron. Generally use 2-3 times can basically eliminate this pest.

two。 Root line pest

Root nematode is a common pest in saffron diseases and insect pests. It generally harms the roots of plants and parasites in the roots to absorb nutrients. At the initial stage, it will slow the growth of saffron and reduce its yield. It will directly lead to the death of the whole plant over a long period of time.

Prevention and control methods: when root line pests are found, 1000 times of methyl topiramate should be used as soon as possible to spray and kill the diseased roots. after spraying and killing, it is best to disinfect the saffron again to avoid the phenomenon of expansion.

3. Aphid pest

This kind of insect pest will generally do great harm to the leaves of saffron, affecting plant photosynthesis, resulting in sagging flowers, and directly leading to the withering of the whole plant in the eyes, and its impact on ornamental.

Control method: this pest can be scraped off directly with a toothpick when it is discovered at the initial stage. If it is serious, it needs to be sprayed with 40% dimethoate EC. Generally, it can be completely killed by spraying 2-3 times.

4. Root rot disease

The disease first erodes and pollutes the diseased roots, then gradually spreads to all parts of the saffron, and finally causes the whole plant to turn yellow, and then gradually wither. This disease can occur at any time in plants.

Prevention and treatment: if the disease is found, the diseased plant should be removed directly, and then the disinfection should be carried out by sprinkling quicklime into the hole of the diseased plant, which will further spread.

5. Sclerotia disease

Sclerotinia sclerotiorum mainly harms the seedlings and corms of saffron. This pest usually occurs in summer and may lead to seed ball rot when it is serious.

Prevention and control methods: when this disease occurs, the infected balls should be removed in time, and then disinfected, so as not to cause the spread of bacteria. Or it can be sprayed directly with a 500-fold solution of 0% topazine wettable powder.

How to deal with the long insects of Gladiolus, disease and pest control of Gladiolus / 3 diseases and 1 pest

The reason why gladiolus is popular is related to the high ornamental value of its flowers, but when planting it, flower friends will cause gladiolus plants to grow insects because of improper maintenance, resulting in yellowing leaves, fewer flowers, and serious death of the whole plant, so we have to find ways to avoid this situation, so how to deal with gladiolus worms? Let's take a look at the prevention and control methods of diseases and insect pests in Gladiolus.

How to deal with the gladiolus long worm

Thrips: this is the most common pest on the gladiolus plant. It usually goes out during the day and hides in the axils of the leaves. When the light is weak at night or on cloudy and rainy days, it will come out to harm the leaves and feed on the leaves, roots and flowers. When the leaves change from green to yellow, there will be white-gray spots on the Corolla, and the petals will eventually curl.

Prevention and control methods: the prevention and control of thrips need to pay attention to the fertilization in the breeding methods of gladiolus, apply more phosphorus and potassium fertilizer to improve disease resistance, and spray 1000 times of dimethoate EC when the disease occurs.

Control methods of diseases and insect pests of Gladiolus

1. Mosaic disease

The affected parts are mainly leaves and flowers. At first, there will be round spots or corner spots on the leaves, then expand into polygons, the color becomes brown, the leaves will be yellow and curled after the disease, the plant will become short, the spikes will become shorter, and the flowers will not be in full bloom.

Prevention and treatment: when planting, you should choose a strong corm that does not contain virus, and you can disinfect it with potassium permanganate solution. Remove the diseased corms in time after the onset of the disease, and then spray the leaves with 58% mancozeb wettable powder 500 times or 75% chlorothalonil wettable powder.

2. Leaf spot

Although the main harmful part is the leaf, but if it is not treated in time, it will infect the bulb, and the leaf spot will lead to brown spots on the leaf surface of Gladiolus, the markings will continue to expand, the color will continue to deepen, and finally the whole leaf will wither. how the corm is infected will affect the reproduction and growth of Gladiolus.

Control methods: like mosaic disease, in the prevention and control of diseases and insect pests of Gladiolus, the prevention means of leaf spot disease is to choose excellent varieties without pathogens to plant. After the outbreak of the disease, the medicament used is 75% chlorothalonil 800 times liquid, or 65% Dysen zinc solution.

3. Fusarium wilt

It mainly harms the corm of Gladiolus, which will infect the whole plant in the later stage. At the initial stage of the disease, small reddish-brown spots will appear on the bulb, and then continue to expand, depression and atrophy, resulting in corm rot and white filamentous bodies. In serious cases, the plant grows poorly, and the flowers will be deformed.

Prevention and control methods: when breeding, the seed ball had better be soaked in formalin solution for 2 hours, then washed with 40 degrees warm water and dried in a cool place for cold storage, and the sown goods also need to be disinfected again. For example, soaking in 500 times carbendazim solution can prevent the occurrence of Fusarium wilt.

What about the long insects of Qionghua? pest control of Qionghua / 2 insect pests 2 diseases / chemical spraying

In the process of cultivating Qionghua, the last thing people want to encounter is the problem of diseases and insect pests, which do great harm to the plant. If it is not prevented in time, it is easy to cause the plant to wither and die. What about the Qionghua insect? How does Qionghua's pest control need to be done?

II. Disease and insect pest control of Qionghua

Insect pest

1. Shell worm

The scale insect is one of the more common diseases and insect pests of Qionghua. This pest mainly feeds on the juice of Qionghua, and will gradually absorb the juice of its body, resulting in a large loss of nutrients in the plant, resulting in the phenomenon of yellowing and wilting of the plant.

Control methods: we must eliminate this pest in time, if the time is prolonged, the impact on the plant is very great. For this pest, we can use 2.5% deltamethrin 3000 times to directly spray.

two。 Aphids

Aphids are a kind of pest in many plants, and Qionghua is no exception. this pest mainly harms the stems and leaves of Qionghua, and it will gradually suck the juice, thus causing Qionghua to shrink to death. it can be said that Qionghua is one of the most harmful diseases and insect pests.

Control method: in the control of aphids, we can directly spray it with 3000 times of aldicarb wettable powder, and disinfect the plants after spraying.

Disease

1. Black spot disease

Black spot is a kind of disease caused by fungi, which has a high incidence among the diseases and insect pests of Qionghua. When this disease occurs, many irregular black spots will appear on the leaves of Qionghua, and will spread gradually with the passage of time. Finally, it leads to the phenomenon of premature senescence of the plant.

Control methods: for black spot, we can use carbendazim wettable powder 500-1000 times liquid to spray the diseased plant, generally spray once every 10-15 days, 1-2 times can be basically controlled.

two。 Root rot disease

Among the diseases and insect pests of Qionghua, root rot is a very harmful disease. the high incidence period of this disease is about March to April every year, so we must pay special attention to it during this period of time. When this disease occurs, the function of absorbing nutrients and water will gradually weaken, and finally lead to the phenomenon of plant rot.

Control method: in the prevention and control of this disease, we can use 50% carbendazim 500 Mel 600 times solution to irrigate the root of the plant, usually once every 5-7 days, and can be basically cured after 2-3 times.
