Experiment of Several Spray Additives on Reducing Pesticides and Improving Their Efficiency in Controlling Wheat Diseases and Pests
Through the experiment of using spray additives to reduce and increase the efficiency of pesticides,verify and evaluate the effect of additives Maifei,Nongjianfei and Qigong on reducing and increasing the effi-ciency of pesticides against wheat diseases and pests,and provide scientific basis for their popularization and application.The results showed that when 80%of the conventional dosage was added to the recommended dos-age of Qigong auxiliary,the electric spray constant spray was used,the efficacy was significantly higher than that of the conventional dosage,and the effect of drug reduction and efficiency increase was significant,but there was no significant difference between the efficacy of Qigong auxiliary added to the recommended dosage and that of the conventional dosage;80%of the conventional dosage is added to the recommended dosage of Maifei and Nongjianfei auxiliaries.The UAV low volume spray is used,and the efficacy is significantly higher than the conventional dosage.The drug reduction and synergism are significant,but there is no significant difference between the efficacy of Maifei and Nongjianfei auxiliaries added to the recommended dosage with the conventional dosage.It can be seen that adding three additives to 80%of the conventional dosage has a rela-tively good control effect on wheat diseases and pests,achieving the goal of reducing drugs and increasing effi-ciency.It can be promoted and applied in practical production.
