随着农村种植结构改变 ,产量高、经济效益好的甜玉米发展很快。但甜玉米易受玉米螟为害 ,早造甜玉米的被害株达 1 8.1 8% ,中、晚两造被害更为严重。为了解决日趋严重的化学农药污染问题 ,我们采用广东省昆虫研究所产业化生产的昆虫病原线虫 ,进行了玉米螟大田防治试验。斯氏线
With the change of planting structure in rural areas, sweet corn with high yield and good economic efficiency has developed rapidly. However, the sweet corn is susceptible to the corn borer. The number of victims of the early sweet corn production reached 8.181%, and the damage was more serious in the middle and late nights. In order to solve the problem of increasingly serious chemical pesticide contamination, we used the industrialized production of insect pathogenic nematodes by the Institute of Entomology of Guangdong Province to conduct the field control experiment on corn borer.
