Let's take a look at the prevention and control methods of peach aphids.

Medicament drying

Mix 40% omethoate with 1 part of omethoate, 1 part of multifunctional botanical synergist and 2 parts of water, and apply a 10 cm wide ring on the trunk with a brush. If the bark is rough, scrape off the old bark before applying medicine. After application, wrap it with newspaper or plastic film.

Trunk injection

Peach trunk injection, that is, the peach trunk with an iron cone oblique puncture hole from top to bottom, deep to the xylem, and then use No. 8 syringe to inject 40% dimethoate, close the orifice, and kill more than 95% of the aphids after 2 or 3 days.

Spray medicament

There are many medicaments to choose from, including 35% endosulfan EC 1500 times, 50% aphid mist 3000 times, 50% phoxim EC 1500 times, 40% omethoate 1500 times, 50% marathon EC 1000 times, 10% imidacloprid (aphid aphid) 5000 times, and so on. In order to improve the control effect, a certain amount of developing agent can be added to the solution, several agents should be used alternately, and the use of a single agent should be avoided as far as possible.

Protect natural enemies

There are many natural enemies of aphids, such as ladybugs, aphid flies, dragonflies, parasitoids, etc., so it is necessary to spray broad-spectrum insecticides as little as possible and avoid spraying in the period when there are many natural enemies, so as to protect natural enemies and use natural enemies to eliminate aphids. It is of great significance to protect the ecological environment of orchards and produce pollution-free green fruits.
