摘  要:
研究了不同生物型雨久花对水星和农得时的耐性差异.耐性生物型的GR50比感性生物型高2.42和2.80倍.禾大壮和西草净的配合使用对耐性雨久花的鲜重防效达95%以上,丁草胺和扑草净、西草净、扑草净的鲜重防效达80%以上.

摘  要:
The different tolerances to pyrazosulfuron-ethyl and bensulfuron-methyl of different biotypes of Monochoria Korsakowii Regel et Maacket were researched. The tolerant Monocho-ria Korsakowii Regel et Maacket to pyrazosulfuron-ethyl and bensulfuron-methyl was discovered in Longjing City in Jilin Province. The GR50 of tolerant biotype was 2.42 times and 2. 80 times higher than that of susceptible biotype . The controlling effect on the fresh weight of tolerant biotype of mixture of molinate and simetryne could reach more than 95 % . The controlling effect of the mixture of butachlor and prometryne, simetryne, and prometryne could reach more than 80%.
