Problems solved by technology

Existing head blight generally adopts cyanene tebuconazole suspending agent mixed with water to make liquid medicine, and electric sprayer is used for spraying control. The main problems of existing wheat head blight prevention and control methods are as follows: one is that the liquid permeability is not good. strong, not easy to enter the inside of the wheat; second, the adhesion of the liquid medicine is not strong, the coverage rate of the liquid medicine is low, and the use efficiency is low; the third is to use an electric sprayer for spraying and control, which has low operating efficiency, high labor intensity, and low safety factor

Abstract

The invention discloses a wheat scab synergistic prevention and treatment method combining a plant protection unmanned aerial vehicle with a plant additive. The method comprises the following steps: 1) preparing a liquid medicine by adding water according to the dosage of a nonionic surfactant 75ml. hm<-2>, 48% cyanogen alkene. tebuconazole suspending agent 4050g. hm<-2> and the water consumptionof 22.5-30kg. hm<-2>, and fully and uniformly mixing, and (2) spraying the pesticide liquid prepared in the step (1) to wheat at the early stage of flowering by using a plant protection unmanned aerial vehicle under a windless or breeze sunny weather condition. According to the invention, the non-ionic surfactant is added into the prepared liquid medicine as a combined plant auxiliary agent, so that the coverage of the liquid medicine is greatly improved, the use efficiency of the liquid medicine is improved to the maximum extent, medicine drops efficiently enter wheat, and the prevention andtreatment effect of wheat scab is remarkably improved, the plant protection unmanned aerial vehicle is adopted for spraying, the prevention and control operation efficiency is high, the safety coefficient is high, the labor intensity is low, and the good prevention and control effect and high economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of wheat disease prevention and control, and in particular relates to a method for synergistic prevention and treatment of wheat scab. Background technique [0002] Scab is an important disease in wheat growth, which is caused by the infection of Fusarium graminearum as the main pathogen. Deoxynivalenol (DON) is produced after the pathogen infiltrates wheat, which has toxic effects on humans and other animals and seriously endangers the health of humans and animals. Existing head blight generally adopts cyanene tebuconazole suspending agent mixed with water to make liquid medicine, and electric sprayer is used for spraying control. The main problems of existing wheat head blight prevention and control methods are as follows: one is that the liquid permeability is not good. Strong, not easy to enter the inside of the wheat; second, the adhesion of the liquid medicine is not strong, the coverage rate of the liquid medi...
