Safety Evaluation and Weed Control Efficacy of Pre-emergence Herbicides in Chrysanthemum Fields
摘要
Abstract
Weeds are one of the main harmful factors affecting chrysanthemum yield.The safety of several pre-emergence herbicides,including S-metolachlor,pyrazosulfuron-ethyl,isoproturon,pyraclonil,flumioxazin,and prodiamine was tested through greenhouse bioactivity tests and field plot trials.The results of safety test on chrysanthemum showed that S-metolachlor exhibited the highest level of safety,without observed significant impact on fresh weight,plant height,or flowering of chrysanthemums plants.Field experiment on weed control efficacy demonstrated that 960 g/L S-metolachlor EC,applied at 648～864 g a.i./ha,effectively controlled weeds in chrysanthemum field,without reducing chrysanthemum yield.In conclusion,S-metolachlor is a suitable pre-emergence herbicide for weed control in chrysanthemum field.关键词
