Abstract
ZJ 0712 is a kind of synthesized strobilurins type novel fungicide, which chemical name is 2- -3-methoxy acrylic acid methyl ester.The patent for ZJ 0712 was applied in China.The efficacy of 10% ZJ 0712 SC was evaluated in laboratory and field against Sphaerotheca fuliginea and Pseudoperonospora cubensis of cucumber.The results showed that the value of EC50 and EC90 was 1.79 and 5.47 μg/mL to S.fuliginea,0.34 and 45.15 μg/mL to P.cubensis.The effect of 10% ZJ 0712 SC was 85.79%~91.33% against S.fuliginea at 10~20 g/hm2, and was 86.70%~90.18% against P.cubensis at 37.5~150 g/hm2,respectively.It is safe to crops at the dosage of the test.
