高粱田苗后除草剂安全性初步评估

Preliminary Evaluation of Herbicide Safety in Sorghum Field after Emergence

为筛选出高效、安全的高粱苗后除草剂,本研究对用于高粱田的12种苗后除草剂在田间进行安全性评估,结果表明:硝磺草酮、炔草酸等7种除草剂对高粱药害较大,莠去津、二氯喹啉酸等5种除草剂对高粱生长没有影响或影响较小,初步明确这5种除草剂在高粱田的安全施药剂量。

In order to screen out efficient and safe herbicides for sorghum after emergence,this study evaluated the safety of 12 herbicides used in sorghum field.The results showed that 7 herbicides,such as mesotrione and Clodinafop acid,were harmful to sorghum,while 5 herbicides,such as atrazine and quinclorac,had little effect on the growth of sorghum.The safe dosage of these 5 herbicides in sorghum field was determined.
