摘　　要：通过脱落宝50%可湿性粉剂在天津、南京两地棉花上消解动态模拟试验,测定出脱落宝在棉花叶片、土壤中半衰期分别为4.6～5.0d,6.6～9.6d;设定剂量范围内,棉籽中最终残留量未检出,土壤中21d为未检出～0.090m gk/g。50%脱落宝W P在棉花上合理、安全的用量为40g/667m 2,70%棉桃干裂时喷雾1次,7d后采收。We determined the half-lives of 50% thidiazuron WP in cotton and soil respectively ,the residue of cotton seeds ,which based on these experiments including degradation dynamics,defferent spray dose, spray times and interval trail. Finally,the reasonable,safty application method of 50% thidiazuron WP in Cotton was made certain.
