摘要
选用甲霜灵(Metalaxyl)为主要成份开发出ND98-1种衣剂,用量在3%以内对大豆生长安全,种子包衣用药量为3%时,防效为95.2%,持效期可达30~40 d(即至开花期),持效期比用58%雷多米尔(WP)拌种多15~20 d。大田示范试验中,平均增产率为32.7%。
Metalaxyl was selected as fungicide to make into the seed dressing agent ND98-1.The results of plot trail showed that the seed dressing agent was safe for soybean seed in 3%, and the control effective was 95.2%. The time of keeping control effective of seed dressing agent treatment was 30~40 days, and was longer 15~20 days than 58% Metalaxyl-mancozeb WP. The results of large field trail showed 32.7% of average yield was added under using the seed coating ND98-1 comparing to 35% Duokefu seed dressing agent.
