① global warming causes pests and diseases, which leads to the increase of pesticide dosage in agricultural production, the occurrence of pests and diseases is closely linked to climate change, if climatic conditions on the growth of pests will greatly reduce the degree of pest occurrence, thus reducing the use of pesticides. Usually, the low-temperature weather will kill the overwintering pests in large quantities, while the warm winter will cause pests and diseases to explode in the coming year. According to the latest monitoring results released by the World Meteorological Organization, 2000-2009 was the warmest 10 since 1880, when climate warming will lead to increased pest and insect activity, resulting in a sustained increase in pesticide usage.
② insecticides still maintain the main position of the international pesticide market, and pesticides, fungicides and herbicides are the main body of the international pesticide market. The proportion of pesticides, fungicides and herbicides in the global pesticide market in 2004 was 25:24:48. In 2009, pesticides still accounted for 25% of the global pesticide market, of which North America and western Europe remained the largest market share, accounting for about 70% of the market (data source: Phillips McDougall).
③ The safety requirements of pesticides are increasing and the global pesticide industry is facing a series of new requirements, that is, over the years, the use of pesticides on the environment and livestock and humans have caused different degrees of pollution, therefore, the international community on pesticides, high efficiency, low toxicity, low residue, pollution-free, and more demanding, Especially in the pesticide industry.
