摘要
2001～2002年进行了80%唑嘧磺草胺WG土壤残留12个月对后茬作物影响的田间小区试验。结果表明, 施用推荐量48 g a.i./hm2和2倍量96 g a.i./hm2,可以安全种植马铃薯、西瓜、高粱、西红柿和葱;施用3 倍量144 g a.i./hm2可以安全种植马铃薯和西瓜,高粱、西红柿和葱有一定的药害,不能种植。48 g a.i./hm2 对较敏感作物向日葵和亚麻有轻微药害,最好不种植,对敏感作物甜菜、甘蓝和油菜有较重药害,不能种植;96、144 g a.i./hm2对向日葵、亚麻、甜菜、甘蓝和油菜药害严重,均不能种植。
Small plot field experiments were conducted in 2001 and 2002 to determine the effect of flumetsulam 80% WG soil residues on succeeding crops 12 months after application. With flumetsulam at the recommended rate of 48 g a.i./ha and at a 2X rate of 96 g a.i./ha, potatoes, watermelons, sorghum, tomatoes, and onions were not injured. At a 3X rate of 144 g a.i./ha, potatoes, watermelons, sorghum, tomatoes, and onions showed some injury and should not be planted. Relatively sensitive crops such as sunflowers and flax showed slight injury following application of 48 g a.i./ha, and should probably not be planted. Sensitive crops such as sugarbeets, cabbage, and rapeseed were injured relatively severely, and should not be planted. Serious injury was also observed on sunflowers, flax, sugarbeets, cabbage, and rapeseed following 96 and 144 g a.i./ha, and these planting situations should all be avoided.
