Abstract
2008–2009 in Jiangsu,Hunan,Heilongjiang,the residual experiment of pymetrozine 25% WP was studied for understanding the security of pymetrozine in Paddy Rice. The results showed when pymetrozine 75 g/hm2 was applied 3 times,detectable residues in rice 7 d after the last application was0.02 mg/kg.
