摘要
[Objective] The paper was to study the effects of Anngro adjuvant under the condition of pesticide reduction.[Method] With rice as the research object,a novel botanical adjuvant Anngro was mixed with 75% trifloxystrobin tebuconazole WDG and 35% chlorantraniliprole WDG at half dosage,and sprayed to control striped rice borer(Chilo suppressalis),rice sheath blight(Rhizoctonia solani) and false smut(Ustilaginoidea oryzae).The rice yield of pesticide reduction was compared with that of conventional application,to explore the cost-saving,effect-increasing,green and environment-friendly diseases and insect pests control technology of rice in Honghu area.[Result] The combined application of Anngro and three dosage forms of pesticides at half dosage had synergistic effect on the control of striped rice borer compared with conventional application at normal dosage,and the effect was improved by 2.67%.The control effects of the two application methods on rice sheath blight and false smut were equiva-lent.There were no significant differences in rice yield and other economic traits.[Conclusion] Anngro can be used as an effective adjuvant in Honghu area,which increases the prevention and control effect of rice diseases and insect pests,reduces agricultural non-point source pollution,and improves ecological environment.It can be used as a pesticide synergistic adjuvant for further demonstration and promotion.
