Method for preserving four main pesticide formulations

Proper storage of pesticides pesticides are kept safe and rational use of pesticides is an important part. Different dosage forms of pesticides also have different storage characteristics. Taking appropriate measures for storage and storage is of great significance for avoiding pesticide reduction, failure and accidents.

(1) Liquid pesticides. Including emulsifiable concentrates, water-based pesticides, etc., which are characterized by flammability and explosiveness. The characteristics of storage and storage are heat insulation and sun protection, avoiding high temperature. Store in a dry and ventilated warehouse. Keep away from fire, power supply and direct sunlight to prevent fire. The stacking operation should be carried out gently, without collision, and the box mouth is facing upward to prevent the pesticide from corroding the cap and leakage.

(2) Solid pesticides. Including powders, wettable powders, tablets, etc., which are characterized by prone to deformation and deterioration, affecting the application operation and efficacy, and the focus of storage is moisture and moisture. It should be stored in a dry and ventilated warehouse and bagged with powdered pesticides. The bottom layer of the warehouse should be separated from the ground by wooden boards, reeds, etc., so as to prevent the lower layer of powder from being agglomerated and affecting the quality of the powder. Pay attention to frequent inspections, especially during the mildew rain season. Pay more attention to moisture protection. If you find that the moisture-absorbing pesticides should be moved to the icy air, dry them, repack them, and do not expose to the sun. Solid pesticides are generally not allowed to come into contact with alkaline substances to avoid failure.

(3) Compressed gas pesticides. Such as methyl bromide, etc., generally packed in sealed steel bottles or special cans. The focus of this type of pesticide storage is anti-leakage and explosion prevention. Like methyl bromide itself is not easy to burn and explode, but it will cause explosion under high temperature and external force impact strong vibration, and methyl bromide is highly toxic gas. Keeping such pesticides should be specially filled, always check whether the valve is loose, cylinders, cans Whether there is damage, whether there is any rotation, whether there is any spillage of pesticides, so as not to cause bad consequences.

(Iv) microbial pesticides. Such as Bacillus thuringiensis, Jinggangmycin, Liuyangmycin, Streptomyces, Beauveria bassiana, etc., which are characterized by high temperature resistance, inability to store, and most susceptible to moisture and mildew failure. Therefore, it must be stored in a low temperature, dry environment, the focus of management is to prevent high temperature and humidity. Attention to frequent inspection, found that there is mildew agglomeration, indicating that it has been contaminated by miscellaneous bacteria, can not be used, and the storage time is no more than 2 years, and try to use microbial pesticides, the shorter the production time, the better.
