摘　　要：以温室盆栽生物测定法,测定乙嘧酚磺酸酯对黄瓜白粉病菌的毒力。结果表明:乙嘧酚磺酸酯的EC50值为5.61μg/g,嘧菌酯的EC50值为7.16μg/g,乙嘧酚磺酸酯对嘧菌酯的T50值为127.6,说明乙嘧酚磺酸酯对黄瓜白粉病具有显著的抑制活性。The toxicity of bupirimate against to cucumber Sphaeotheca fuliginea were tested in greenhouse.The result showed that EC50 of bupirimate were 5.61μg/g,EC50 of azoxystrobin were 7.16μg/g,T50 of bupirimate to azoxystrobin were 127.6,The inhibition of bupirimate was obvious effective.
