Abstract
To improve the existing pesticide control effects of Nilaparvata lugens, reduce the risk of Nilaparvata lugens resistance,the field experiment was carried out to study the control effects of 60% pymetrozine and acetamipride WG 1#(5∶1), 2#(1∶10), 5%acetamipride EC, 50% pymetrozine WG. The results showed that under the equal effective conmponents, the controlling effect of 2#(60 g/hm2)10 days after spraying was 78.95% than 5% acetamipride EC(720 g/hm2), and it could reduce 100% organic solvent usage.Contrast 50% pymetrozine WG(150 g/hm2), the control effect was no significant differences, but 40% of the dosage of active ingredients could be reduced. Such as 2 # can be enhanced by adding assistant for prevention and control of Nilaparvata lugens, the recipe can be used in production practice.
