摘要
1989年蔗田果尔药效试验结果表明:果尔在蔗田的最佳使用量是5 g(有效成分)/亩,在此剂量下与常规除草剂阿特拉津100g(有效成分)/亩的除草效果相当,而用药量则少20倍。果尔的最适施用期及施药方法是芽前土壤处理。芽前处理对甘蔗及其间作物花生安全而无药害。果尔对一年生杂草的除草效果在处理后70天达8级以上。果尔所有处理区的蔗及茎花生产量均高于或接近人工除草区。
Result from efficacy trial of GOAL in 1989 indicated that the optimum applicating rate of Goal is 5g(ai)/mu,that is 20-fold lower than the applicating rate of atrazine at 100 g(ai)/mu with equal efficacy of weed control.The best time and method of application of Goal is pre-emergent soil treatment.It is safe on sugarcane and peanuts without phytotoxicity. Coal was effective on annual weeds with grade over 8 in 70 DAT.The yields of sugarcane and peanuts from Goal treated plots were equal or higher than the manual weeding plot.
