With the rapid development of agriculture , the amount of pesticides has also increased significantly. The specialization of the spraying of pesticides has been increasingly valued by farmers. It is very important to strengthen farmers' control of pests and diseases and correct spraying of pesticides.
The scallions are waxy vegetables with a layer of white powdery wax on the surface of the leaves. In the prevention and control of pests and diseases, because the surface of the leaves has a layer of wax, the sprayed liquid is in the form of water droplets, which cannot be infiltrated into the interior of the plant and is lost, which does not achieve the desired control effect. So how do we spray it? Today, Xiaobian will give you a summary.
First, take the washing powder or soap with a weight of 0.1%, dissolve it thoroughly with warm water, and use it as an additive for the liquid. When the liquid is poured into the sprayer 1/3, add the additive, and then add a sufficient amount of water to spray.
However, it should be noted that some pesticides will reduce and lose control effects when mixed with washing powder, such as stone sulphur, zinc, thiophanate, and thiophene. The pesticides that must be used immediately after mixing are dimethoate, malathion, and the like.
