How to treat eggplant nematode disease? Eggplant has bugs with what method to treat

The control methods of root-knot nematodes are as follows.

1. Reasonable crop rotation.

When planting eggplant, it should be reasonably rotated with non-solanaceae crops such as onion and garlic for 2-3 years. The nutrient soil for seedling cultivation should be sterile soil, and it should be dried 2-3 weeks in advance before use.

2. Soil treatment.

In addition to raising seedlings with disease-free soil, seedbeds can also be treated with chemicals. Avermectin can be used as an emulsified oil, diluted with the right amount of water, sprayed on the seedbed, and then tilled and mulched. Soilless seedling raising is an important measure to control root-knot nematode disease, which can not only prevent eggplant from suffering from root-knot nematode disease in the early stage, but also has better seedling quality than soil seedling.

3. Field management.

Choose high dry land, use deep furrows and high furrows for cultivation, and there is no water in the field. Turn the soil a little deeper to minimise the source of insects, and apply enough mature organic fertilizer not to mix with the residue of the last crop. After sowing, use soil as mulch, and spray insecticide and sterilizer at one time before transplanting.

Cultivate strong seedlings, plant at a reasonable density, water appropriately, remove diseased roots, leaves, and plants in a timely manner, burn out of the field, and apply medicine or quicklime to the diseased holes.

4. Pharmaceutical prevention and control.

Before planting, the thiazolium phosphate granules are mixed with fine dry soil, sprinkled on the soil surface, and then rotated once. Planting should be carried out as soon as possible after use to make the control effect better.

Eggplant is a common home-cooked vegetable that many people love to eat and is easy to grow in their own garden. But in the process of planting eggplant, many people often find that the yield of eggplant they grow is always unsatisfactory, and compared with others, it has been reduced by half

Eggplant is a common home-cooked vegetable that many people love to eat and is easy to grow in their own garden. But in the process of planting eggplant, many people often find that the yield of eggplant they grow is always unsatisfactory, and it has been reduced by half compared with others, in addition to the immature planting technology, most of them are the result of pests and diseases. Today, let's talk about the prevention and control methods of eggplant root-knot nematode disease, let's learn together.

Disease characteristics of root nematode disease.

Eggplant plants infected with the disease are mainly dwarf and weak, and there will be a lot of spherical nodules in the roots, and some serious root epidermis will rot, which will lead to plant death if not prevented and treated in time, seriously affecting the yield.

Root nematode disease is a common pest and disease in the process of eggplant cultivation, disease * and disease fertilizer are the main diseases, overwintering larvae, invade from the roots of the plant, produce root knots or tumors. For example, if the farmhouse fertilizer we commonly use is not completely decomposed, the root-knot nematode eggs will enter the field soil and multiply in large quantities.

Methods for the prevention and control of root nematode disease.

1. Reasonable crop rotation.

When planting eggplant, it should be rotated with non-solanaceae crops such as onion and garlic for 2-3 years. The nutrition of seedlings should be sterile and dried 2-3 weeks in advance before use.

2. * Soil treatment.

In addition to treating disease-free* seedlings, seedbeds can also be treated with chemicals. Avermectin EC can be used, diluted with an appropriate amount of water, sprayed on the seedbed, and mulched. If conditions permit, no * seedlings can be used, which is an important measure to prevent and control root-knot nematodes, which can not only prevent eggplant from being damaged by root-knot nematodes in the early stage, but also seedlings are better than soil seedlings.

3. Field management.

Choose a field with high and dry terrain, use deep furrows and high furrows for cultivation, and there should be no stagnant water in the field. Plough the ground deeply first to minimize the source of insects, and at the same time apply enough decomposed organic fertilizer, which should not be mixed with crop residues. After sowing, use the medicine * to do mulching*, and spray 1 insecticide before transplanting.

Cultivate strong seedlings, reasonable dense planting, reasonable irrigation, timely removal of diseased vines, diseased leaves, diseased plants, and take them out of the field to burn, diseased holes to apply pesticides or quicklime.

4. Pharmaceutical prevention and control.

Before planting, mix with thiazolephos granules and fine dry *, sprinkle it on the * table, and then rotary tillage once, after application, it should be planted as soon as possible, so that the control effect will be better.

The above is all about eggplant root nematode disease, and in addition to root nematode disease, it is also necessary to pay attention to the impact of other pests and diseases in the process of planting eggplant. Only by achieving scientific prevention and control can we effectively help the high yield of eggplant.

Once eggplant is attacked by insects, it will directly affect its quality and nutritional value. Therefore, we must carefully observe and prevent the appearance of insect pests when buying or planting eggplants. Next, let's talk about several methods when eggplants have bugs.

The first method is to use organic pesticides to crack down on bugs. We can use onions, peppers, etc. to make a natural and organic pesticide and use a sprayer to water or spray the eggplant, which can reduce the damage of chemical pesticides to the eggplant, and long-term use can make the soil healthier.

The second method is to drizzle water over the roots of the eggplant. This is a relatively safe control method, which does not harm the plant and can play a role in repelling insects. Just drizzle the roots of the eggplant with water at regular intervals.

The third way is to pick the bugs and choose a more suitable location. Some bugs may hide in the eggplant, we need to pick them out by hand, and change the planting location of the eggplant before the next planting, there may be different bugs in different locations, and changing the location can avoid repeated infestation of the eggplant.

The above three methods can be used in combination with each other, when there are insects in the eggplant, we need to talk about the timely and effective control measures, so as not to affect the quality and health of the eggplant.

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.

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.

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. Select disease-resistant varieties for cotton blight, implement crop rotation, do not apply nitrogen fertilizer, and pay attention to drainage 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 58% methyl stupid number cream, spray 1 time 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 rotting 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.
