What specific pesticides are effective for controlling red spider mites on eggplant?

Eggplant is one of the main summer vegetables and is cultivated throughout China. During cultivation, it is prone to common pests such as red spider mites, aphids and whiteflies. So, what specific pesticides are there for treating red spider mites on eggplant?

1. Specific pesticides for red spider mites on eggplant

For red spider mites on eggplant, specific pesticides such as 73% propargite EC at 1200 times dilution and 40% dimethoate EC at 1000 times dilution can be sprayed for control.

2. Control of common pests on eggplant

1. Red spider mites: For agricultural control, keep the soil moist regularly, avoid excessive drought, and promptly remove weeds and fallen leaves and branches to reduce pest sources. For chemical control, strengthen pest monitoring, keep them at the spot-and-patch occurrence stage, and spray pesticides such as 73% propargite EC at 1200 times dilution and 40% dimethoate EC at 1000 times dilution for control.

2. Aphids: For control methods, it is advisable to apply pesticides early and keep them at the spot-and-patch occurrence stage. For agricultural control, promptly clean up residual plants and fallen leaves in the field after vegetable harvest and remove weeds. For chemical control, spray pesticides such as 2.5% deltamethrin EC at 2000-3000 times dilution, 50% pirimicarb at 2000 times dilution and 20% Lubaosu at 2500 times dilution for control.

3. Whiteflies: For control methods, add insect-proof nets and cover with silver-grey plastic film and yellow sticky boards. Whiteflies have a negative taxis to silver-grey, so silver-grey 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 exploiting their taxis to yellow. For chemical control, use one tube each of Lubaobao and Shijiening mixed with 15 kg of water and spray for 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.

Eggplant pest control is mainly preventive; if infested, pesticides must be applied promptly for control, otherwise the growth of eggplant will be affected.
