摘要
对不同浓度70%甲基硫菌灵可湿性粉剂进行番茄叶霉病防治田间试验研究。结果表明：在番茄叶霉病发病初期,1hm2用70%甲基硫菌灵可湿性粉剂的577.5~787.5g,对水900 kg,对番茄叶霉病有较好的防治效果。喷药间隔期为7d,共喷3次。药后7 d各处理防效在77.35%~83.12%之间,且对番茄生长安全。
With different concentration of 70% thiophanate- methyl WP to control tomato leaf mold in the field,the result show that it was the high control efficiency to tomato leaf mold as it was early stage with70% thiophanate- methyl WP 577. 5 ~ 787. 5g / hm2 added water 900 kg. thiophanate- methyl WP were sprayed three times,the interval was 7 days. The control efficiency was 77. 35% ~ 83. 12% after 7days,and it was safe to tomato.
