水田除草剂苯噻酰草胺·苄嘧磺隆悬浮剂的应用试验

The Test of Appling Mefenacet o Bensulfuron Methyl SC in Paddy Field

对26.5%苯噻·苄悬浮剂和53%苯噻·苄可湿性粉剂进行了盆栽试验,经对水稻生育性状(株高、分蘖数、有效穗数、产量)和对稗草防除效果调查分析。结果表明,苯噻.苄悬浮剂与苯噻.苄可湿性粉剂相比,在对水稻安全的同时,减少农药用量而不显著降低对稗草防除效果。

The pot experiment was carried out for 26.5% mefenacet o bensulfuron methyl SC and 53% mefenacet o bensulfuron methyl WP. The reproductive traits of rice, i.e., plant height, the number of tiller, the effective number of spike, yield, and the controlling effect to barnyard grass were analyzed. The results showed that compared with mefenacet o bensulfuron methyl WP, mefenacet o bensulfuron methyl SC reduced the amount of pesticides without a significant reduction for the control to barnyard grass and it was safe for rice at the same time.
