What are the common diseases and insect pests during the growth of eggplant, the main vegetable in summer? What are the prevention and control methods? What kind of medicine can be cured?

Eggplant, also known as hanging vegetable, purple eggplant, dwarf melon, etc., is a relatively common vegetable in our country. At present, it is planted in most areas, and during the period of eggplant growth, it is inevitable that there will be all kinds of diseases and insect pests. Therefore, if you want to plant well, you need to do a good job in pest control. What are the common diseases and insect pests during eggplant growth? What are the prevention and control methods? What kind of medicine can be cured?

What are the common diseases during the growth of eggplant?

1. What are the symptoms of eggplant suffering from stunning disease? How to prevent and cure it?

Quenching disease is the most common disease in eggplant seedling stage, which is mostly caused by mold infection, and usually overwinters in the soil. When the conditions are suitable, oospores are produced, and then spread to other plants in the way of Rain Water, sex, etc., resulting in eggplant stem discoloration and withering, until shrinking death.

Prevention and control methods:

The main results are as follows: (1) strengthen the technology of inter-garden management: select the seedlings with good quality and good disease resistance when planting, and disinfect the soil deeply before planting to avoid the breeding of bacteria.

(2) Seedling site selection: the plot with good drainage, good ventilation and sunny was selected to improve the disease resistance of the plant.

(3) Pesticide control: for the diseased plants that have been damaged, 72.2% Pulike water agent or chlorothalonil wettable powder can be sprayed.

2. What are the symptoms of eggplant with leaf mold? How to prevent and cure it?

Leaf mildew is a common disease during the growth of eggplant, which is mostly infected by fungi, which usually attach to the surface of the seed and infiltrate into the inside of the seed, causing all kinds of disease spots on the leaves and stems of eggplant, until mildew layer or plaque is produced, causing the plant to wither and die. Some of them will survive the winter safely on the ground, and when the temperature is suitable in the next year, they will breed spores and spread to other plants with Rain Water or other pathogens, causing widespread infection and causing diseases.

Prevention and cure method

(1) strengthen the technology of inter-garden management: control the density when planting, so as not to raise the ground temperature and breed bacteria.

(2) Seedling site selection: in order to improve the disease resistance of the plant, the plots with good drainage and ventilation should be selected as far as possible.

(3) cleaning up weeds, branches, etc.: after harvest, all the weeds, diseased branches and weeds in the garden should be cleared to one place in time, and burn deeply in order to avoid disease infection.

(4) Chemical control: 47% Garinon wettable powder and 60% Fangmaibao No. 2 water-soluble powder can be sprayed to prevent bacteria from spreading and harming other plants.

3. What are the symptoms of eggplant with Fusarium wilt? How to prevent and cure it?

Fusarium wilt is the most common disease of eggplant after planting, which is mostly caused by bacterial or fungal infection. It usually occurs in humid and warm environment, especially in rainy season or acidic soil, causing the leaves to wither and turn yellow until the whole plant dies.

Prevention and cure method

(1) take precautions in advance: the disease of eggplant Fusarium wilt usually begins in May-July or September-October, so before that, the health status of plants in the garden should be properly checked, and the withered grass, withered branches and weeds in the garden should be cleaned up and eliminated.

(2) Seedling bed and seed disinfection: before sowing, the seeds were soaked in 55 ℃ warm water for 15 minutes, and the soil was thoroughly disinfected in order to prevent root infection and damage the plants.

(3) avoid crop rotation: when planting eggplant, avoid continuous cropping with non-eggplant vegetables for more than 3 years, and properly watering and ploughing them, so as to reduce bacterial infection.

(4) Chemical control: for the damaged plants, 50% carbendazim wettable powder or 15% carbendazim water agent can be used for foliar spraying to reduce the occurrence of diseases.

4. What are the symptoms of eggplant with cotton blight? How to prevent and cure it?

Cotton blight is a common disease in the fruiting period of eggplant, also known as rotten eggplant, which is mostly caused by fungal infection. It generally occurs seriously in the plum rain season, which can cause fruit rot and affect yield.

Prevention and control methods:

(1) strengthen the inter-garden management technology: select the land with good drainage and good ventilation to prevent the breeding of virus in the plum rain season.

(2) soil disinfection: before planting seeds, the soil or seeds should be disinfected to prevent bacterial infection from harming the plants.

(3) avoid crop rotation: crop rotation with non-Solanaceae vegetables is prohibited for more than three years on the land where diseases have occurred, and reasonable fertilization and watering are used to promote strong plant growth and cooperate with chemical treatment when the disease occurs.

5. What are the symptoms of Sclerotinia sclerotiorum in eggplant? How to prevent and cure it?

Sclerotinia sclerotiorum is one of the most common diseases in seedling and adult stage of eggplant, which is mostly caused by fungal infection, which can wither the stems and leaves of the plant until the whole plant dies, affecting the yield.

Prevention and control methods:

(1) sterilization and disinfection of soil: Sclerotinia sclerotiorum is mostly infected by soil fungi, so before planting, carbendazim wettable powder must be used to disinfect the soil to prevent parasitic growth of bacteria and infect other plants.

(2) strengthen the technology of inter-garden management: when planting, we must control the density to prevent the soil temperature from rising to breed bacteria. At the same time, before the peak of the disease, we should often check the garden and destroy the residual branches and diseased branches in order to cut off the fungal infection.

Second, what are the common pests during the growth of eggplant?

1. What are the symptoms of eggplant with aphids? How to prevent and cure it?

Aphids are a common pest during the growth of eggplant, which occur in general planting areas, mainly eat the stems and leaves of eggplant, and can eat up the whole stem and leaves in serious cases, causing the plant to die.

Prevention and control methods:

(1) artificial control: before the beginning of winter, the withered and diseased branches in the garden should be burned to avoid the occurrence of insect pests in the following year.

(2) Pesticide control: if aphids are found, special agents such as marathon emulsion and aldicarb wettable powder can be sprayed directly.

(3) protect natural enemies: aphids also have natural enemies, such as parasitic wasps and aphid flies, so several natural enemies can be properly bred to prevent the occurrence of insect pests.

2. What are the symptoms of eggplant with red spider? How to prevent and cure it?

Red spider is a common pest during the growth of eggplant, which occurs in general planting areas. It mainly eats the juice of eggplant leaves, which makes the whole leaves wither and die.

Prevention and control methods:

(1) cleaning up the garden: after the eggplant is harvested, the miscellaneous branches, withered branches, diseased branches and diseased leaves in the garden should be burned and buried in time, so as to prevent the larvae from overwintering in the cracks and harm the fruit of the following year.

(2) Pesticide control: if pests are found, they can be sprayed and killed in time with insecticides.
