What pesticide works well to control pests on eggplants
Eggplant is a vegetable we often eat, but during the growing process, it is prone to pest problems, and if measures are not taken in time, its growth will be affected. So, what pesticide should be sprayed when eggplants have pests?
1. Red spider mite
For agricultural control, keep the soil moist frequently, avoid excessive drought, remove weeds and fallen leaves in time, and reduce pest sources. For chemical control, strengthen pest monitoring, keep it under control at the spot-and-patch occurrence stage, and choose 73% propargite emulsifiable concentrate at 1200 times dilution, 40% dimethoate emulsifiable concentrate at 1000 times dilution and other pesticides for spray control.
2. Aphids
For control methods, it is advisable to apply pesticide early and keep them under control at the spot-and-patch occurrence stage. For agricultural control, after vegetable harvest, clean up the residual plants and fallen leaves in the field in time and remove weeds. For chemical control, choose 2.5% deltamethrin emulsifiable concentrate at 2000-3000 times dilution, 50% pirimicarb at 2000 times dilution, 20% Lübaosu at 2500 times dilution and other sprays for control.
3. Whiteflies
For control methods, add insect-proof nets, and cover with silver-gray plastic film and yellow sticky boards. Whiteflies have a negative taxis to silver-gray, so silver-gray plastic film can effectively repel whiteflies. If whiteflies have already occurred in the greenhouse, yellow sticky boards can be set up to trap and kill them by using the yellow taxis of whiteflies. For chemical control, choose 1 tube each of Lücaibao plus Shijiening mixed with 15 kg of water for spray control. In addition, plant growth regulators such as Fengshou No. 1 and Yunda 120 can also be sprayed to alleviate the adverse effects of pests on functional leaves.
4. Mites
36% kemanying emulsifiable concentrate at 1000-1500 times dilution, 5% flufenoxuron emulsifiable concentrate at 2000 times dilution, 1.5% abamectin emulsifiable concentrate at 3000 times dilution and other pesticides can be used for spray control.
5. Leafminers
When there are 3 larvae on a leaf, before the larvae reach the 2nd instar (when the mines are very small), after the dew dries between 8-11 o'clock, when the larvae begin to move on the leaf surface or when many larvae emerge from the mines, start spraying 25% banqianjing emulsifiable concentrate at 1500 times dilution or 5% yitaibao emulsifiable concentrate at 2000 times dilution. The control time is best kept at 8-12 o'clock, the peak of adult emergence.
Red spider mites, aphids, whiteflies, mites, and leafminers are five common pests of eggplant. We hope the above control methods are helpful to everyone.
