In recent days, the weather was dry, resulting in a large amount of aphids in vegetable fields. The locust will suck the vegetable sap, and at the same time it will secrete honeydew to cause coal pollution. More seriously, it will spread the virus and cause virus disease.
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.

In response to the current insect situation, vegetable farmers should actively take countermeasures to control aphid damage in time with imidacloprid, acetamiprid and other highly effective and low-toxic pesticides. Use 10% imidacloprid wettable powder 10 ~ 20 grams per acre, or 3% acetamiprid EC 15 ~ 20 ml, add water 30 kg spray. Vegetable bases can be used yellow traps to kill aphids, conditions can use double net (insect nets and shade nets) cover cultivation, reducing the number of medications. At the same time, it is necessary to promptly remove the old crops that are endangered by the weeds in the fields and by the aphids in the surrounding areas and reduce the sources of invasive insects.
