Pesticides: biopesticides. Biocides are divided into: Bacillus thuringiensis, insect viruses, plant extract three categories Xinxiang efficiency and low toxicity pesticides, with easily obtained, low-cost, long controlled, efficient, economical, safe, pollution-free and efficient Zhejiang low toxicity pesticides, highly compatible with the environment and other characteristics, is the best choice of the current production of pesticide pollution-free green vegetable production. Pesticides development direction: Typically, a lot of cold weather will kill overwintering pests Zhoukou efficiency and low toxicity pesticides, and warm winter will make large-scale outbreaks of pests and diseases in the coming year. According to the latest monitoring results released by the World Meteorological Organization efficiency and low toxicity pesticides, 2000-2009 1880 systems worldwide since meteorological records for the warmest 10 years, global warming will lead to pest activity increased, resulting in killing dosage continued to grow.
