What pesticides are used in the oil drought in the yard?

Oil drought is one of the destructive pests on the earth. About 250 of them are pests that are seriously harmful to agroforestry and horticulture. Oil and drought vary in size, ranging from one to ten millimeters in length. So what kind of pesticides are used in the yard for oil drought?

What kind of pesticides are used in the oil drought in the yard

Oil drought in the yard can use imidacloprid, acetamiprid, thiazine copper, acetamiprid, buprofezin and other pesticides. The natural enemies of oil drought are ladybugs, aphid flies, parasitoids, aphid-eating gall mosquitoes, crab spiders, lacewings and entomopathogenic fungi.

II. Prevention and control methods of oil drought

1. Drug prevention and treatment.

When a large number of aphids are found, spray pesticides in time. Spray the plant twice with 1000 times of 50% marathon emulsion, 1000 times of 50% fenitrothion emulsion, 3000 times of 50% aldicarb wettable powder, 3000 times of 2.5% deltamethrin emulsion, or 3000 times of 2.5% methamphetamine emulsion, or 40% imidacloprid water solvent 1500 × 2000 times, etc. Prepare chili water with the proportion of 1RV 6MUR 1RV 8 (boiled for about half an hour), spray detergent water with the ratio of 1RV 20muri 1RU 30, or spray the mixed solution of detergent, urea and water with the ratio of 1RV 20MUR 400, spray the plants continuously for 2 times. For aphids covered with wax powder, such as peach powder aphids, 1% soapy water or washing powder should be added to increase adhesion and improve control effect.

two。 Artificial prevention and control.

Brush white at the base of the trunk in autumn and winter to prevent aphids from spawning; combined with pruning, cut off the damaged branches and residual flowers, burn them centrally, and reduce the overwintering insect population; scrape or brush off the dense overwintering eggs on the bark in winter, clean up the residual branches and leaves in time, and reduce the overwintering eggs; when a small amount of aphids are found on flowers in spring, you can use a brush dipped in water, or tilt the potted flowers under tap water to rinse.

3. To protect predators.

There are many natural enemies of oil drought, including ladybugs, lacewings, aphid flies and parasitic wasps, which have a strong inhibitory effect on aphids. Try to apply as few broad-spectrum pesticides as possible, avoid applying pesticides during the peak period of natural enemy activities, and artificially raise and release aphids under certain conditions.

Oil drought is widely distributed all over the world, but it is mainly concentrated in temperate regions. In addition, species diversity is much lower in the tropics than in temperate zones.
