几种杀菌剂防治番茄溃疡病田间药效评价
Field Control Effect of Several Fungicides on Tomato Canker
【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。
【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.
