What kind of pesticide does aphid use?

Aphids, also known as cloying insects and honey insects, are a class of herbivorous insects that are widely distributed worldwide, but mainly concentrated in temperate regions and are one of the most destructive pests on earth. So, what kind of pesticides do aphids use?

1. What pesticides do aphids use?

The plants can be sprayed with 50% Marathon emulsion 1000 times, 50% Fenitrothion emulsion 1000 times, 50% Pirimicarb WP 3000 times, 2.5% Deltamethrin emulsion 3000 times, 2.5% Methomyl emulsion 3000 times or 40% Imidacloprid aqueous solvent 1500~2000 times for 1~2 times.

II. Control methods of aphids

1. Drug Control

When large numbers of aphids are found, timely pesticide spraying (see above). It can also be used to prepare chili water (boiled for about half an hour) in the ratio of 1:6-1:8, or spray detergent water in the ratio of 1:20-1:30, or spray detergent, urea and water mixed solution in the ratio of 1:20:400, and spray the plants continuously for 2~3 times; for aphids such as peach powder aphids, which are covered with wax powder, when applying any chemicals, 1% soap water or detergent should be added to increase adhesion and improve control effect.

2. Artificial control

In autumn and winter, whitewash the base of the trunk to prevent aphids from laying eggs; combine pruning, cut off the injured branches and residual flowers, burn them in a centralized manner, and reduce the number of overwintering insects; scrape or brush off the dense overwintering egg mass on the bark in winter, clean up the residual branches and leaves in time, and reduce the number of overwintering eggs; when a small number of aphids are found on flowers in spring, they can be washed with a brush dipped in water, or the potted flowers can be tilted under tap water to rotate and wash.

3. Protection of natural enemies

Aphids have many natural enemies, ladybugs, laceflies, aphids and parasitic wasps, etc., which have a strong inhibitory effect on aphids. Apply broad-spectrum pesticides as little as possible, avoid applying pesticides at the peak of natural enemy activity, and artificially raise and release aphid natural enemies if conditions permit.

Because aphids do great harm to plants, when planting crops, aphids are mainly treated according to the principle of "prevention first, timely elimination".
