In the following, there are symptoms and treatment methods of various pests and diseases. Interested friends can know about them.

2. Prevention and control of diseases and insect pests of clove flowers

1. thorn moth pest

Symptoms: The appearance of this pest is similar to moth, but the volume is relatively small, generally about 13-18mm, it mainly feeds on the leaves of clove flowers, will gradually eat its leaves, if not treated for a long time, it may make clove flowers become a bare rod.

Control method: When dealing with this pest, we can choose to use 50% phoxim EC 1000 times to spray the pest.

2. shell pest

Symptoms: In the prevention and control of clove pests, scale insect is a common pest, which mainly harms the leaves of clove flowers. It will suck the juice from the leaves, causing the leaves to lose nutrients and gradually turn yellow and wither. It is a very harmful pest.

Control methods: in the emergence of this pest must be treated as soon as possible, if the time dragged on can easily lead to excessive loss of nutrients clove and wither. For this pest we can use 40% omethoate 1000 times solution to spray kill.

3. Wilt disease

Symptoms: Wilt is a disease caused by bacteria. In the early stage of the disease, yellow spots appear on the leaves of lilacs, and gradually spread, eventually causing the leaves to fall off and finally spreading to the roots, causing the whole plant to die.

Control method: For this disease, we can use 50% carbendazim WP 1000 times to spray the diseased plants, generally spraying once every 7- 1 - 2 days, after 1-2 times, it can be cured basically.

4. powdery mildew

Symptoms: powdery mildew disease is a common disease in the prevention and control of lilac flowers.

Colorful summer flowers should not only exist in the cool clothes and fresh mountains, but also bloom in the room, embellished around us, and share a world with us to create a full room fragrance of "flowery world." Petals, wisps of fragrance around the body, pleasant and refreshing state of mind naturally presented. In leisure time, carefully tend to the flowers and plants full of infinite vitality, the harvest process is always accompanied by the optimistic spirit of self-entertainment, dull, hot swept away, leaving only refreshing and full of fragrance.

Flower into the room effect of multi-function 1: filter air In summer, the use rate of air conditioning in the room is extremely high, the doors and windows are closed, and the air circulation is not good. Therefore, it is appropriate to raise some flowers that can filter air in the room. Most flowers carry out photosynthesis during the day, absorb carbon dioxide, release oxygen, breathe at night, absorb oxygen, release carbon dioxide, and cacti, ostachys and other categories are the opposite. These flowers, which can filter air, are kept in a room with other flowers, which can effectively balance the content of indoor oxygen and carbon dioxide and keep indoor air fresh. Effect 2: Remove toxicity Chlorophytum, aloe vera, sanse-tail orchid can absorb a large number of indoor formaldehyde and other pollutants, eliminate and prevent indoor air pollution. In particular, hanging orchid, put a pot in the room, within 24 hours, its leaves will be indoor air carbon monoxide and other harmful gases "eat", its effect even exceeds the air filter. Milan, orchids, cloves, cacti, Tianzhu and so on can effectively purify the air. Camellia can resist sulfur dioxide and other harmful substances, Lagerstroemia indica indoor sulfur dioxide, hydrogen chloride, chlorine, hydrogen fluoride and other toxic gas resistance is strong. Mei has the ability to monitor the pollution of sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene and aldehyde in the environment. Once sulfide appears in the environment, its leaves will appear stripes, or even yellow and fall off. Because flowers have these functions, the newly renovated rooms are more suitable for raising these flowers. It should be pointed out that these functions of plants are limited, so it is necessary to open windows frequently to make air convection. Function 3: Kill germs Rose, osmanthus, violet, jasmine, lemon, rose, pink, lily of the valley, Lagerstroemia and other aromatic flowers volatile oils produced by significant bactericidal effect. Lagerstroemia, jasmine, lemon and other plants, within 5 minutes can kill diphtheria and dysentery bacteria and other protozoa. Rose, carnation, lily of the valley, violet, rose, sweet-scented osmanthus and other plants send out fragrance on tuberculosis, pneumococcus, Staphylococcus growth culture has a significant inhibitory effect. It is important to note that although flowers have many benefits, do not use the room as a "greenhouse". Most flowers release carbon dioxide at night, absorb oxygen, and most of the rooms at night are closed, plus the carbon dioxide exhaled by the soil, human body and pets in the flowerpot, which will increase the concentration of carbon dioxide, causing hypoxia in the human body and affecting health. Experience of Flowers in Summer Veteran flower grower: Uncle Xie, 61 years old, retired, 40 years of flower cultivation. Key points: pay attention to the placement. It's important to position them according to their habits. Flowers have Yin Xi Yang points, especially in summer according to the habits of each flower to decide the placement. Orchid, azalea, camellia, clivia, etc. are negative, should be placed under the south wall or north balcony, morning and evening light is enough. Rose, lotus, osmanthus, jasmine, orchid and so on are positive, whether in the building balcony or downstairs, should be placed in the sunny place, so as to blossom more, fragrance thick, growth flourishing. Flower veteran: Miss Liu, 25 years old, university lecturer, 5 years of flower cultivation. Points of advice: timely and appropriate watering. Summer to flower watering, should be timely amount, early, late watering and not watering at noon. And it is best to irrigate the accumulated rainwater. When there is no rainwater, tap water can be poured, but tap water should be dried for more than one day before pouring. The watering frequency is determined by the dryness and wetness of the flowerpot. The soil in the pot should be dry and wet to ensure that the flower roots can breathe normally. Generally, watering is done once or twice a day. The leaves can also be sprayed appropriately. For acid-loving flowers, it is best to pour 0.2% to 0.3% of black alum water to prevent iron deficiency and chlorosis. Some fleshy root flowers, such as Clivia, etc., can not withstand the sun, can be more dry at noon when moderate spray some water on the leaves. Some drought-tolerant flowers, such as cacti and Crassulaceae, should drink less water because they are easy to rot. Flower veteran: Ms. Zhang, 37 years old, civil servant, 14 years of flower cultivation. Tips: pay attention to moisturizing sunscreen. The key to building balcony flower cultivation is humidity, that is, moisturizing and sunscreen. Summer sunlight is strong, if the flowers are moved indoors, it will cause lack of sunlight and poor growth. Males are not afraid of strong sunlight, but they still need shade at noon. If it is neutral, it needs appropriate shade. If it is a balcony pot flower, it can be moved indoors from 10 a.m. to 3 p.m. every day. If it is negative, it is absolutely necessary to prevent contact with strong light. It is best to set up shading nets for flowers to protect them from sun and hail. In addition, according to different varieties, water trays are placed under the flowerpots to ensure humidity. Flower veteran: Mr. Sun, 43 years old doctor, 32 years of flower cultivation. Key points: prevention and control of pests and diseases. Rainy season is the season of pot flower diseases and insect pests, so 20% methyl tolbutine WP 1000 times solution or 50% carbendazim WP 1000 times solution should be sprayed once every half month to prevent diseases and insect pests. When aphids, red spiders, scale insects and other pests occur, spray 40% dimethoate emulsifiable solution 1000 times to 1500 times, or 20% methomyl (fenpropathrin) emulsifiable solution 1500 times to 2000 times, spray once every 10 days, spray 3 times continuously. Flower veteran: Grandma Guo, 74 years old, retired, 53 years of flower cultivation. Key points: fertilization should be appropriate. Fertilization should be appropriate in summer. Too much fertilizer, flowers can not absorb, anti-injury roots. Generally, flowers blooming in summer are more resistant to high temperature, and more fertilizer can be applied appropriately, such as crape myrtle, jasmine, balsam, cockscomb, dahlia, etc., which can be supplemented with fertilizer at flowering stage to make it flourish; some fruiting flowers such as kumquat, five-color pepper, etc., can make it bear more fruits after applying phosphorus fertilizer after flowering; and tropical foliage plants, such as rubber tree, turtle bamboo, etc., should apply nitrogen fertilizer to make its leaves greener. Thin fertilizer more, too high concentration is easy to cause fertilizer injury. How to prevent diseases and insect pests Prevention and control of pests and diseases is an important link in the process of flower cultivation. The expert solution to this problem is: 1. Detergents kill white flies. White flies not only suck leaf juice, but also secrete mucus to make leaves wither. A spoonful of detergent and 4 liters of water can be mixed evenly, sprayed on the leaves, sprayed once every 5 - 7 days, until the white flies are eliminated. 2. Milk kills ticks. The flower stems and leaves are often accompanied by ticks, which can cause the branches and leaves to change color and wither. You can mix half a cup of fresh milk, 4 cups of flour and 20 liters of water, then filter it with gauze, spray the liquid on the branches and leaves of flowers, not only killing ticks, but also killing eggs. 3. Flour for pest control. If potted flowers have pests and diseases, take a small amount of flour, first with cold water to make paste, then with appropriate amount of boiling water to make a 1:50 solution, spray in sunny days, will have good results. 4. Watermelon rind plus cigarette butts can also cure insects. Will wash watermelon skin buckle on the pot soil, can be a few days without watering, is the best nutrition pot flowers. If you put a few cigarette butts under the melon skin, tar and nicotine can penetrate into the basin soil and kill many common bugs. 5. In addition, after the tea leaves are dried, they are sprinkled on the surface of the basin to prevent insects from growing on the flowers. Summer Flower Care Jasmine summer is jasmine bloom, sufficient water and fertilizer conducive to flower flourish. Spray leaves with clear water on sunny days, which can obviously stimulate flowering. Orchids summer is the growth season orchids, should ensure moisture and nutrients. When the disease occurs, Tobucine can be sprayed once every 10 days. Azalea in summer azalea growth slow, in a semi-dormant state, avoid sun exposure and excessive fertilization, should be shaded. Watering 1 to 2 times a day, and spraying water on the leaves and ground to keep moisture and cool down. Peony bogey hot afraid of wet, summer plants should be placed in a cool place, do not have to water too much, keep the pot soil moist can, so as not to rot roots. Rose likes fertilizer water, to ensure sufficient supply of fertilizer water, every half month to apply decomposed bean cake water, stop fertilization in mid-July. Black spot and powdery mildew are easy to occur in summer. Bordeaux mixture is used for the former, and carbendazim is used for the latter. Spray once every half month for control. Milan likes light and heat, and Milan grows vigorously in summer. Before and after flowering, apply thin alum fertilizer every 10 days, and often spray water on the foliage.

4. Watermelon peel and cigarette butts can also control insects. Buckle the washed watermelon peel on the potted soil without watering for several days, which is a good nourishment for potted flowers. If you put a few cigarette butts under the peel, tar and nicotine can seep into the soil and kill many common bugs.

5. In addition, after drying the brewed tea, sprinkling it on the surface of the potted soil can also prevent flowers from growing insects.

Skillful maintenance of flowers in summer

Jasmine summer is the full bloom of jasmine, sufficient water and fertilizer is conducive to blooming and leafy. Spraying foliar surface with clear water on a sunny day can obviously stimulate flowering.

Orchid summer is the peak growing season of orchids, which should ensure water and nutrients. When the disease occurs, topiramate can be sprayed every 10 days.

Cuckoo summer cuckoo growth is slow, in a semi-dormant state, avoid hot sun exposure and excessive fertilization, should be shaded. Water once or twice a day, and spray water to the leaf surface and the ground to moisturize and cool down.

Peony avoid heat and humidity, summer plants should be placed in a ventilated and cool place, do not need too much watering, keep the basin soil moist, so as to avoid rotting roots.

Rose likes fertilizer and water, so it is necessary to ensure an adequate supply of fertilizer and water, apply rotten bean cake water every half a month, and stop fertilization in mid-July. Black spot and powdery mildew are easy to occur in summer. the former is sprayed with Bordeaux solution and the latter with carbendazim every half a month.

Milan likes light and heat, and Milan grows vigorously in summer. Thin alum fertilizer should be applied every 10 days before and after flowering, and water should be sprayed to the leaves frequently.
