Attention to the preparation of the five pesticides water

Avoid using running water running water in the preparation of pesticides because of impurities, with its easy to plug the spray nozzles dispensing the same time, the suspension will damage resulting from liquid precipitation.

Avoid using well water because the well water contains minerals preparation of more pesticides, especially calcium, magnesium and more, these minerals and liquid mixture prone to precipitation and reduce the efficacy.

Avoid any increase too much water because the water will reduce the concentration of pesticides, thus reducing the efficacy or even failure. In addition, pesticides can also cause excessive loss of water, pollute the environment.

Bogey in the rain windy days or when spraying under the hot sun will make the powder or liquid pesticide drift, and rain spraying pesticides pharmaceutical efficacy easily reduced rainfall, spraying in the hot sun, plant metabolism, stomatal opening can easily lead to injury, and easy to make volatile efficacy and reduce the control effect. 8-11 am the best when the application time, 3-6 pm.

Also note that: When mix of several pesticides, not every kind of medicine they all add additional water once, but with a variety of drugs are used to calculate the concentration of water. For example, 500 times the preparation of urea plus 1,000 times the thiophanate methyl, is 2 plus 1 thiophanate-methyl urea were added 1000 parts of water. Should be watered with liquor, that is, first a small amount of warm water the liquid of open, add water to the desired concentration, to fully dissolved, increase the suspension to improve efficacy, prevent the injury.
