18.6%拌·福·乙悬浮种衣剂不同拌种时间对棉蓟马的防治效果

The Different Seedvax Time of 18.6% Amicarthiazol Thiram·Acephate Suspended Seed-coating Preparation Against Cotton Thrips Effect

采用田间小区和温室试验,研究了18.6%拌·福·乙悬浮种衣剂对棉蓟马的防效及在棉株体内的消解动态。结果表明:18.6%拌·福·乙悬浮种衣剂可以提高棉花出苗率,增幅为18～23个百分点,乙酰甲胺磷在棉苗体内的残留时间为32d左右,18.6%拌·福·乙悬浮种衣剂提前拌种对棉花出苗和对棉蓟马的防效没有太大影响。

In order to appraise the insectproof effect of 18.6% amicarthiazol·thiram·acephate suspended seed-coating preparation and in the cotton adult plant in vivo degeneration time,we use the field plot and the greenhouse experiments,have studied this kind of seed-coating preparation against effect to the cotton thrips and the resolution tendency in the cotton plant.The result indicates： 18.6% amicarthiazol·thiram·acephate suspended seed-coating preparation can raise the cotton rate of seedlings emergence,the increased range is 18 percentage point-23 percentage points,the residual time of acephate in the young cotton plants is about 32 days,this seed-coating preparation to use ahead of time which has not affected too greatly to the cotton and cotton thrips against effect.
