谷物防护剂在六十年代国外已广泛应用于储粮害虫防治,由于使用安全、杀虫效果好、残效期长,对防治仓虫的感染和为害起了良好的作用。但多年来,我国储粮害虫的防治,多依赖熏蒸剂,对防护剂的使用目前正处于试验和推广阶段。防护剂能否在我省推广应用,我们选用了六种防护剂(其中二种为国外提供的),进行防虫保粮药效试验,从中筛选适合我省高温高湿的农药,以便在南方推广应用。
Grain protectant in foreign countries in the 1960s has been widely used in the prevention and control of stored grain pests, due to the use of safety, insecticidal effect, long residual period, the prevention and control of insects and insects infection and damage played a good role. However, over the years, the prevention and control of stored grain pests in our country depend more on fumigants, and the use of protective agents is currently undergoing trials and promotion. Whether the protective agent can be popularized and applied in our province, we choose six kinds of protective agents (two of which are provided abroad) to conduct pest-and-disease food-preserving efficacy test to screen pesticides suitable for high temperature and high humidity in our province for promotion in the south application.
