How to control eggplant aphids? What should I do if there are aphids on the eggplant?

Prevention and control methods: Agricultural control: vegetable fields should be reasonably laid out to reduce aphid migration in the field; In areas with conditions, sows less cruciferous vegetables in summer and cleans the fields to cut off or reduce the source of aphids and poisons of autumn vegetables.

Silver film to avoid aphids: 17 cm wide silver-gray film is spread around the seedbed, and silver-gray film strips are hung above; Laying silver-gray membrane strips at intervals in vegetable fields can avoid aphids or reduce the migration of winged aphids. Yellow plate aphid:

In spring and autumn, field cuttings coated with organic oil yellow plates (60 cm higher than crops) to trap winged aphids to reduce the amount of aphids in the field. Granules anti-aphid treatment: smoke with smoked aphid granules for 12 hours, and the dosage per mu is kilograms.

Or use 1% dimethoate or aphid pine granules to apply to people when eggplant sowing, about 15 kg per 1000 square meters, labor-saving, residual effect up to 1 month, good effect, but also protect natural enemies. Pesticide control: 10 18 grams of 50% anti-aphid (aphid mist) wettable powder per mu, 2000 3000 times liquid spray, the effect of killing aphids is good, and it can protect a variety of natural enemies.

You can also choose 50% malathion EC, 50% diaziphos EC, 25% quinthion EC, 40% dimethoate EC 1000 times each, or deltamethrin EC, 40% chrysanthemum EC 2000 4000 times each for spraying. or 20% of the 2000 3000 times of the rapid killing of butyrine EC or 20% of the 3000 times of the emulsifiable concentrate.

Aphids, also known as vegetable aphids, greasy insects, etc., including peach aphids, radish aphids and cabbage aphids, are one of the main pests of cruciferous vegetables such as cabbage.

Use silver gray film to avoid aphids. Pharmaceutical prevention and control: Commonly used agents are:

50% aphid-asciopy fog wettable powder or anti-aphid carb wettable powder, 10 18 grams per mu, spray 30 50 kg of water. This agent is specially designed to control aphids, does not kill natural enemies and bees, and is especially suitable for harvesting fields. Once net or 10% imidacloprid wettable powder, the dosage per mu is 5 10 grams to 100 kg of water.

Many people asked the old farmer: What should I do if there are aphids on the eggplant?

Answer: Eggplant aphids are extremely fecundive, and many clusters are harmed by young leaves at the top of new shoots, which stuns the growth of eggplant, and can spread viruses and reduce yield. In terms of prevention and control, it is better to eliminate aphids before they multiply in large quantities, and it is better to use large-scale unified control and control of pesticides, including pepper trees, peach trees, locust trees, pomegranate trees, weeds and other susceptible hosts around the vegetable field.

Spraying: When the rate of aphids in the field is greater than 5%-10%, and the amount of aphids per plant is greater than 5, pesticide spraying control is carried out. Spray 1000-1500 times of 10% imidacloprid, acetamiprid and other insecticides, prevent 1 time every 7-10 days, and spray 2-3 times in a row.

It can also be used to spray 1000-2000 times of carbofuran butylthiol in the flowering and fruit-setting period of eggplant, and the effect is better. At the same time, combined with insect control, spraying 100 grams of potassium dihydrogen phosphate per mu and foliar fertilization can prevent eggplant from falling flowers and fruits and improve yield.

Plant-derived pesticide control: use matrine (gram aphidin) water solution 400 times liquid or aphidicide (spore content 2 million ml) 250 times solution, or biological pesticide thousand insect gram wettable powder 1200-1600 times liquid spray control.

Auxiliary means: 1. Add water with plant ash (the ash and water left after the hay point is burned out according to 1:5) to soak and spray the damaged plants for control.

2. Use sugar, vinegar, wine, and water (white sugar is boiled with hot water, the water is not easy to be excessive, and then vinegar and wine are added, and the sweetness can be smelled), put it in a small cup, and wait until the winged aphid is active in the evening, and put it next to the affected plant for prevention, because aphids like sweetness.

Hello dear according to your question 1, brown striation disease can occur throughout the whole process, and the middle seedling stage can cause the seedlings to fall suddenly and the seedlings to wither. The high temperature and rainy season in summer are especially frequent, and the disease of continuous cropping plots is more serious. Prevention and control methods:

For seed disinfection, 75% chlorothalonil wettable powder 800 times liquid can be used to soak seeds for 2 hours, rinse with water repeatedly after fishing, and then germinate and sow or dry for later use. When seedlings are sterilized, self-prepared with nutrients * seedlings or seedlings are raised in seedbeds, seedlings can be treated harmlessly by means of mixing*, spraying or root irrigation, and it is advisable to treat them before and after sowing. Remove the diseased leaves and fruits as soon as possible after the onset of the disease, and then use 600 times of 50% iprodione wettable powder, or 2000 times of 25% azoxystrobin suspension for spray prevention and control, and avoid taking drugs before rain, snow, cooling and other weather the next day to prevent the occurrence of drug damage caused by the inability to release wind in time.

2. Cotton blight disease mainly harms the fruits, leaves, and young stems of eggplant, and eggplant seedlings will fall and die suddenly after being damaged, and the disease will be aggravated in high temperature and humidity, heavy stubble land, weak growth, partial application of nitrogen fertilizer, and extensive management of fields. Prevention and control methods: 40% aluminum triethylphosphonate wettable powder 200 times or 65% zebsen wettable powder 500 times can be used for spray prevention at the seedling stage, and preventive drugs should be paid attention to in high-risk seasons such as before the rainy season and fruiting period.

After the onset of the disease, 500 times of 64% cream-manganese-zinc wettable powder and 500 times of 58% methyl frost-manganese-zinc wettable powder can be sprayed for prevention and control, and the interval between drugs is about 7 days, which can have a good prevention and control effect. 3. Verticillium wilt is a medium and low temperature disease, the fungus mainly invades from the root wound, if it lasts for a long time from planting to flowering, the onset is early and severe. Prevention and control methods:

In order to improve the disease resistance of seeds, it is necessary to disinfect the seeds, and the pesticide seed dressing can be carried out with 50% Ketodan wettable powder or 50% Fumei double wettable powder, and then sprinkle 50% carbendazim wettable powder into the seedling * to disinfect the soil, and the seedling stage to the onset of planting can be used to irrigate the roots with 300 times of more than 30% Fukexin wettable powder or 500 times of 500 times of carbendazim wettable powder, and pay attention to uniform medication, which can play a good prevention and control effect.

Hello dear, happy to answer for you. Eggplant disease and pest control methods: 1. Early blight:

1) It is necessary to carry out crop rotation for more than 3 years, apply fully decomposed organic fertilizer, increase potassium and phosphorus fertilizer, and enhance tree potential. Remove diseased leaves and branches in time, plant reasonably densely, drain water in time after rain, maintain ventilation and light transmission, and reduce humidity. (2) Before planting, the seeds can be soaked in warm water at 52 °C for 30 minutes, or mixed with fludioxonil suspension seed coating agent to dry, and then germination and sowing, and the shed can be disinfected with sulfur fumigation for 1 night.

2. Cotton blight: (1) First of all, we should select disease-resistant varieties, rotate crops for more than 2 years, apply enough fully decomposed organic fertilizer, increase phosphorus and potassium fertilizer, and enhance tree potential. Remove diseased fruits and leaves in time, plough the soil to reduce the source of disease, plant reasonably densely, remove stagnant water in time after rain, and maintain ventilation.

2) Seed dressing was carried out with fludioxonil suspension seed coating agent and 35% refined methyl cream emulsified seed coating agent. 3. Verticillium wilt: (1) First, select disease-resistant varieties, apply fully decomposed organic fertilizer, increase potassium and phosphorus fertilizer, enhance tree potential, remove diseased plants in time, and reduce the source of disease.

2) At the seedling stage, 50% carbendazim 500 times solution and 96% copper sulfate 1000 times solution can be used for root irrigation, and then transplanted with medicine. 4. Brown streak: (1) Implement crop rotation for crops, increase organic fertilizer, potassium fertilizer and phosphate fertilizer, increase tree potential, drain water in time, and maintain ventilation.

2) After the results, you can spray 10% hexaconazole 1500 times, or 10% difenoconazole 1500 times, or 25% prochloraz EC 800 times, use 1 time every 5 days, 2-3 times in a row. 5. Fusarium wilt: 500 times of 50% carbendazim wettable powder or 1000 times of 15% dichlorfen water solution can be used for root irrigation, and 200ml can be used for each plant.

6. Botrytis cinerea: (1) Choose eggplant varieties that are resistant to low temperature and low light, control temperature and humidity, plant high ridges, plant reasonably densely, pay attention to ventilation, and drain water in time after rain. Apply organic fertilizer, potassium fertilizer and phosphate fertilizer to eggplant, increase tree potential, remove residual branches and diseased fruits in time, and bury or burn them in a concentrated manner.

2) The following agents can be used for prevention and treatment in the early stage of the disease: 800 times of 50% iprodione wettable powder, or 1500 times of 25% azoxystrobin suspension, or 1200 times of 40% pyrimetrychlor suspension. Common diseases of eggplant include early blight, cotton blight, Verticillium wilt, brown streak, wilt, gray mold, etc.

1. Early blight: In the early stage of leaf disease, there will be round or nearly circular lesions, with brown edges, gray-white in the middle, and concentric wheel patterns. 2. Cotton blight:

The disease occurs at the adult stage, and the initial stage is water-immersed, round, sunken, yellow-brown lesions, with ring lines. 3. Verticillium wilt: it can be infected at the seedling stage, and it mostly shows symptoms after fruit set, and generally develops from bottom to top or from one side to the whole plant.

If my answer is helpful to you, please click on the praise and kiss. Your efforts are important to me, and your support is what drives my progress. Finally, I wish you good health and a happy life!

Verticillium wilt is selected from disease-free seeds, or the seeds are soaked in 50% carbendazim 500 times solution for 7 hours for disinfection; Implement crop rotation, clean the farm, uproot the diseased plants in time and burn them in a centralized manner, and sprinkle lime for disinfection. At the beginning of the disease, the roots were irrigated with 50% carbendazim 500 times, 250 ml per plant, and 1 time in 7 10 days. 2. Cotton blight is selected from disease-resistant varieties, crop rotation is implemented, nitrogen fertilizer is not applied partially, and drainage is paid attention to after rain.

At the beginning of the disease, spray once every 6 7 days with 500 times of 90% Phytophthofen 500 times, and spray 3 4 times in a row. 3. Brown streak disease selects disease-resistant varieties, disinfects seeds and seedbeds, and implements crop rotation. At the beginning of the disease, spray 600 times of 40% synergistic Rui poison mold, or 400 times of 58% manganese zinc of methyl stupid number cream, spray once every 7 days, and spray 2 3 times in a row.

4. For cataplexy, select high-dryness plots as seedbeds, disinfect the bed soil, and apply rotten fertilizer. At the beginning of the onset of the disease, seedlings can be sprayed with 50% carbendazim 500 600 times solution, or 75% chlorothalonil 600 times solution. Diseased plants are immediately removed.

The pests of eggplant include red spiders, cotton bollworms, tobacco worms, and potato tuber moths. The prevention and control measures are timely weeding, cleaning the countryside, deep turning before winter, and controlling the source of blind insects. When insect pests are found, 50% phoxanthion EC can be sprayed.
