【摘要】 评价6种杀菌剂对番茄溃疡病的田间防治效果,为番茄溃疡病防控提供科学依据。在番茄始花期至挂果期进行田间防治。结果显示,供试浓度下第3次药后9 d防治效果最好的药剂为38%喹啉铜·中生菌素悬浮剂SC (70.32%),相对较好的药剂为33.5%喹啉铜SC (63.43%)、5%中生菌素SC (60.29%)和2%春雷霉素AS (58.17%),建议这4个药剂在番茄溃疡病中后期进行轮换施用;46%氢氧化铜WG、77%硫酸铜钙WP防治效果相对较低,可在该病始发前期施用。更多还原

【Abstract】 The field control effects of six fungicides on tomato canker were evaluated to provide scientific basis for disease prevention and control. The results showed that the best fungicide was 38% quinoline copper ·Zhongsheng mycin SC(70.32%) 9 days after the third application, and the better fungicides were 33.5% oxine-copper SC(63.43%), 5% Zhongsheng mycin SC(60.29%) and 2% Kasugamycin(58.17%). It is suggested that the four fungicides should be applied alternately in the middle and late stage of tomato canker; the control effects of 46% copper hydroxide WG and 77% copper calcium sulfate WP were relatively low, which could be applied in the early stage of the disease.更多还原
