Greenhouse vegetable pesticide application to be especially careful

Application of pesticides talk about science, especially in winter greenhouse vegetable pesticide application especially. Otherwise, not only fail to control effect, but also prone to injury. Therefore, the application of pesticides to pay attention to ten bogey.

A pesticide preparation hanged because running water running water impurities, with its easy to plug the low pressure sprayer dispensing nozzle, while also undermine the liquid suspension to produce precipitation.

Two hanged formulated pesticides because well water well water contains minerals more, especially calcium, magnesium and more. These minerals are mixed with the liquid chemical is easy to produce, reduce the efficacy precipitate formed.

Three bogey any excess water will increase the amount of water to reduce the concentration of pesticides. Sprayed on crops, leaving only a very small amount of pesticides, not enough to kill pests, and some pesticides even completely ineffective. Excess water can also cause loss of pesticides, resulting in environmental pollution. Thus,water sprayer in the preparation of pesticides, their use according to the concentration range, strict control of the amount of water.

Four bogey free to increase the amount of pesticide production and sales of pesticides before being allowed to go through rigorous field trials, and then determine dosage, administration time, frequency of administration, the actual use of the data. Therefore, in accordance with instructions on the required amount of pesticide that can achieve the control effect, and increase the dosage not only increased investment, but also to make crops produce injury, increase the amount of pesticide residues in agricultural products, increasing environmental pollution.

Five Note unreasonable application of pesticides can increase some pesticide mixing control effect, reduce the dosage, or reach Cordyceps rid of pests or effect, and mixed use more labor. However, some pesticides can not be mixed use, such as organophosphorus pesticides in most varieties of pesticides encountered alkaline or alkaline medium will quickly decompose and failure. Mix pesticides in need, we must understand the nature of various pesticides, characteristics, to ascertain whether it can be mixed, the best guide for technicians and then mix.
