氟唑菌酰胺对水稻纹枯病的防治效果研究

Study on Fluorine Pyraoxystrobin Amide Control Effect on Rice Sheath Blight

[目的]筛选防治水稻纹枯病的最佳药剂、剂量及方案。[方法]通过田间药效试验测定了氟唑菌酰胺单剂系列产品和广谱治疗性杀菌剂对水稻纹枯病的田间防治效果。[结果]氟唑菌酰胺单剂BAS70004F、BAS70001F、欧博防治水稻纹枯病效果较好,药后15 d的防治效果达到70%以上。[结论]氟唑菌酰胺单剂系列产品BAS70004F、BAS70001F和欧博防治水稻纹枯病的最佳使用剂量分别为165、795、795 m L/hm2。

[Objective] The present study was carried out to screen the best medicament, dose and regimen for prevention and control rice sheath blight.[Methods] The effect of fluoride myclobutanil amide single agent series products and fungicides with broad spectrum was determined in the field experiments.[Result] The results showed that fluoride myclobutaniI amide single agent BAS70004F, BAS70001F, Oubo had better control effect for rice sheath blight than the other treatments,with control efficacy above 70% after 15 days of pesticide application.[Conelusion] The optimum dosage of fluorine myclobutanil amide single agent series products BAS70004F, BAS70001F and Oubo for controlling of rice sheath blight was 165 mL/hm^2,795 mL/hm^2 and 795 mL/hm^2, resoectivelv.
