How hot season only reasonable use of pesticides

Safe use of pesticides has been a concern for farmers, but in the actual production but has not been brought to our attention, blind medication continues to occur, resulting in a serious waste pesticides, injury occur frequently; while for applicators is a poison , especially in the hot season, which is even more prominent. For this reason, to remind farmers rational drug use.

First, improving the utilization of pesticides.

Attention to increase adhesion agents. Outdoor use of pesticides should be selected crops resistant to rain erosion, cream and other more appropriate surface residues of these pesticides on the plants longer, whereas powder, liquid, etc. are relatively poor. Many crops, there blade surface or thick hair wax layer, such as corn, onion, ginger, taro, etc., the liquid in the hair, easy to form droplets on the wax layer, can not fully contact with the surface of plant leaves, can Silicones in pharmaceutical and other additives added to enhance the pharmaceutical effects.

Second, appropriate to reduce the concentration of drug

Most of the efficacy of pesticides as the temperature rises, the efficacy will be enhanced, so the hot season medication should be taken to minimize the amount of liquid, especially pharmaceutical hormones is particularly note the dosage weight can easily lead to injury of happen. Therefore, according to changes in temperature reasonable adjustments pharmaceutical concentrations.

Third, pay attention spray quality

In fact, during the drug crop spraying, the crop can be attached to the blade surface pesticide droplets is limited, when the pressure sprayer spray volume exceeds a certain limit, the leaves on the tiny droplets will agglomerate into large droplets and rolled down, the loss, but the blade attached to the lower amount of pesticides. General requirements for aerosol spray droplet mass distribution, high coverage to wet the surface does not drip appropriate plants, thus requiring the use of spray atomization effect, reduce the liquid waste. Note also that a comprehensive spraying, especially some of the pests prefer spawning in the dorsal damage, especially when spraying agent attention.

Fourth, a reasonable spraying to prevent poisoning

Pharmaceutical, pesticide spraying to prevent corrosion of the skin, the use of volatile pesticides must pay attention to the use of masks, while prohibiting the midday heat in summer time household sprayer spraying pesticides, spraying should be selected in the summer before 9 am or after 4 pm, to avoid injury place. Continuous application time not too long.
