摘要
进行了氮硝基脲类农药对水稻稻瘟病菌、水稻细条病菌室内抑制作用的初步研究。结果表明 :氮硝基脲的间氯代衍生物对水稻细条病菌有明显的抑制作用 ,其最佳抑制浓度为 2 .0 0× 1 0 - 4g/ml,抑制效果在 4 8h内为 1 0 0 % ,72h内为 75.85% ,但此类农药对水稻稻瘟病菌没有抑制作用。
Experiments were conducted to test inhibition of the N nitrophenyl ureas to Pyricularia grisea sacc and Xanthomonas campestris Pv. oryzicola. The results showed that M CL had apparent inhibition to Xanthomonas campestris Pv. oryzicola. 2.00×10 -4 g/ml was the best concentration in the experiments and its inhibition could reach 100% in 48 hours and 78.85% in 72 hours. The N nitrophoyl ureas didn't show inhibition to Pyricularia grisea sacc.
