| 摘 要： | 研究了粉剂除草剂(14%乙·苄可湿性粉剂)颗粒表面活性改良后除草剂对稻田杂草的除草效果.结果表明,两试验点每公顷用改良后除草剂600 g 15 d后的防效达到88.2%、79.7%,与常规除草剂750 g的防效相当;30 d后,其防效仍为89.1%、88.0%,但常规除草剂750 g/hm2的防效明显下降,仅为64.6%和73.7%.因此,除草剂改良后能显著减少使用量、提高防除效果和延长除草有效期.

| Abstract: | The weed control efficacy was studied by using the particle surface activity improved herbicide that improved on base of the normal herbicide(14% mixture of bensulfuron-methyl and acetolchor).The results showed that the improved herbicide with the treatment at dosage of 600 g/hm2 after 15 days could get the effective weed control of 88.2% and 79.7% respectively in two tested sites.Their weed control effects were equal to that of normal herbicide with treatment at dosage of 750 g/hm2.The improved herbicide could maintain a high level of effective weed control of 89.1% and 88.0% after 30 days treatment. But the normal herbicide would reduce the weed control after 30 day treatment,only being 64.6% and 73.7%,suggesting that the improved herbicide had a very long effective weed control period. |
