Eggplant begins to grow flowers and fruits, how to control pests and diseases?

In the process of eggplant growth, there are many pests and diseases, which brings great losses to the normal growth of eggplant, and the main pests and diseases are as follows:

The main insect pests are mites, thrips, whiteflies, green worms, etc

1. Mites.

Mites are one of the most important insect pests of eggplant, which occur throughout the year, and mites are divided into red and white spiders, tea yellow mites, two-spotted leaf mites, etc., which mainly harm leaves and fruits, especially young leaves. The main symptoms of mites are yellowing of leaves, spider silk on the surface of leaves, rough and dull fruit surface, and even deformed fruits.

The control method of mites is mainly prevention, and avermectin and pyridoxin can be sprayed. If there is already mite damage, you can spray bifenazide, ethoxazole, spirofenolate, acetazole nitrile, etc., the effect of compound profenofol is better, and the dosage of profenofol can be combined to prevent pesticide damage.

2. Thrips hazards.

Thrips is currently the most difficult pest to control on eggplant, there is no one, it occurs throughout the year, mainly harms the leaves and fruits, the back of the leaves is smooth, the surface is green, the fruit stalk is rough, and the fruit surface is rough, which affects the normal growth of the fruit.

Thrips control must be carried out in advance, once the outbreak is difficult, usually can be sprayed acetamiprid, thiamethoxam, etc. If thrips are found to be harmful, foliar sprays such as emamectin benzoate microemulsion, chlorfenapyr, ethyl spinosad, spirometallethyl ester, etc., can be flushed if necessary, and the insecticidal effect is more thorough.

3. Whitefly damage.

The whitefly is also the main pest that affects the eggplant, mainly harming the leaves, causing the leaves to turn yellow, lose photosynthesis, and eventually the leaves dry up, which generally occurs seriously in late spring and summer and autumn.

The control of whitefly can be sprayed in advance with endidinepymetrozine, acetamiprid, etc., if whitefly damage has occurred, it can be controlled with endimidam, dinotefuran, spirometallethyl ester and other alternate compound control.

4. Harm green worms.

Green worms mainly occur in summer and autumn, and the harm to eggplant is not small, mainly harming leaves, which can be controlled with emamectin benzoate, chlorantraniliprole, indoxacarb, etc.

The above are the most important insect pests, spraying control can be combined with silicone and other synergists, can effectively improve the efficacy, can be used with smoke smoke shed at night, the control effect is more thorough.

Eggplant diseases mainly include gray mold, blight, leaf spot, leaf mold, etc

1. Botrytis cinerea.

Botrytis and blight are the most important diseases, which generally occur seriously in high humidity and low temperature, mainly harming stems and fruits, especially the most serious damage to fruits, and the whole plant will be infected with serious diseases, and gray mold and rot appear at the lesion site.

For this kind of disease, first of all, we must increase the temperature, reduce the humidity in the shed, you can spray Pythium, enoyl frost urea cyanide and other prevention in advance, if the disease has occurred, you can use Kaiser, iprodiamide, fluridine and other spray control.

2. Leaf spot disease.

Leaf spot disease mainly affects the leaves, with brown spots on the leaves at the onset and dry up the entire leaf in severe cases.

For the prevention and control of leaf spot, pyraclostrobin and chlorothalonil can be sprayed in advance for prevention and control, and if the disease has been on, benzoxystrobin, bromonitrile and other sprays can be used.

Do a good job of pruning, and the growth process can be ventilated and light. Do a good job in fertilizer and water management in a timely manner, pay attention to the application of phosphorus and potassium fertilizers during the flowering and fruiting period, and can also be sprayed on the foliar surface.

Eggplant has long flowers and fruits, and it is easy to get anthracnose, which can be prevented and controlled by spraying with fungal agent with water!

Eggplant insect pests generally have red spiders, and they are sprayed with miteline mixed with water foliar sprays!

1. Choose disease-resistant varieties.

2. Do a good job of seed disinfection. Soak in 10% aqueous solution of trisodium phosphate, or 400 times of potassium permanganate, for 30 minutes, rinse the liquid medicine on the seeds repeatedly, and then soak the seeds to promote hunger and germination.

3. Use containers for root protection and seedling, and do a good job of avoiding aphids during the seedling period, and at the same time sprinkle irrigate the disease Laling virus K (anti-disease), anti-poison No. 1, 83 anti-drug agent and phyto-disease spirit and other agents to improve the immunity of plants to viral diseases; Scientific application of fertilizer and water to ensure the healthy growth of plants.

4. After colonization, regularly spray 500 times of 20% virus A wettable powder, virus Bike, etc. for prevention.

5. In the early stage of the disease, in addition to continuing to spray 20% virus A wettable powder 500 times regularly, virus bike and other prophylactics, it is best to spray 2% bacterial gram (Ningnanmycin) 200 times.
