为了进行春雷霉素WP和常规化学农药在防治粳稻主要病害的比较研究,在水稻不同生育期分别施用春雷霉素WP和常规化学农药,进而研究春雷霉素WP和常规化学农药防治粳稻主要病害的效果。结果表明,2%春雷霉素WP在稻瘟病和稻曲病的防效均高于其他药剂,在纹枯病的防效低于拿敌稳75%WG和300g/L爱苗EC。施用药剂小区的产量比较中,2%春雷霉素WP略低于拿敌稳75%WG和300g/L爱苗EC。春雷霉素WP在粳稻各病害的防效上不亚于常规化学农药,由于春雷霉素WP对环境及人畜危害较低,具有很高的利用价值。
In order to comparatively study on the control of the main diseases of japonica rice with kasugamycin WP and conventional chemical pesticides, kasugamycin WP and conventional chemical pesticides were applied at different growth stages of rice to study the effects of kasugamycin WP and conventional chemical pesticides on the main diseases of japonica rice effect. The results showed that the control effect of 2% kasugamycin WP on rice blast and rice false smut was higher than that of other pesticides, and the control effect on sheath blight was lower than that of 75% WG and 300 g / L acacia EC. The yield of 2% kasugamycin WP was slightly lower than that of 75% of WG and 300g / L of acacia EC. As a result, kasugamycin WP is as good as conventional chemical pesticides in the prevention and treatment of various diseases in japonica rice. Since kasugamycin WP is less harmful to the environment and people and animals, it has high utilization value.
