Technical Field

The invention relates to the technical field of pesticide application, in particular to a pesticide anti-drift spray auxiliary agent for aerial pesticide application and a using method thereof.

Background

With the improvement of agricultural aviation technology, the aviation pesticide application technology is rapidly developed. Especially, the plant protection unmanned aerial vehicle does not need a special runway, is flexible to control and high in pesticide application efficiency, and is widely applied to land areas where ground machinery such as paddy fields, high-stem crops, hills and mountains is difficult to enter at present. However, compared with the spraying height of the conventional ground machine, the aerial spraying is higher, the spraying amount is lower, and the particle size of droplets is smaller, so that the droplets in aerial application are more distant and more sensitive to crosswind under natural conditions, and the serious drift is generated, so that the pesticide utilization rate is reduced, and even the pesticide damage to other crops at the periphery is caused.

In order to reduce the drift of pesticide, an anti-drift auxiliary agent is required to be added into the liquid medicine when the pesticide is applied. The currently used aviation spraying auxiliary agent directly selects the auxiliary agent used for conventional ground application on one hand, and optimizes the auxiliary agent used for ground application aiming at the characteristics of aviation spraying on the other hand. However, the spraying assistant used in the current market is mainly used for improving the spreading and attaching effects of the liquid medicine droplets on the crop targets during ground pesticide application, and is difficult to play a role in preventing floating in the aerial spraying process.

Therefore, the preparation of the spray auxiliary agent specially used for reducing the aerial spray drift has important significance for improving the effective utilization rate of pesticide, reducing the influence of pesticide application on the surrounding environment and improving the deposition and adhesion effects of fog drops on the crop target.

Disclosure of Invention

Aiming at the problems of serious pesticide droplet drift phenomenon, low liquid medicine utilization rate, poor adsorption effect and the like in the current aviation pesticide application process, the invention provides a pesticide anti-drift spray assistant for aviation pesticide application and a use method thereof. The auxiliary agent can change the fog drop spectrum of the spraying liquid medicine, reduce the drift of the fog drops and increase the deposition rate and the attachment effect of the fog drops, thereby achieving the purposes of improving the effective utilization rate of the pesticide, reducing the environmental pollution and improving the control effect of plant diseases and insect pests.

In order to solve the technical problems, the invention provides the following technical scheme:

on one hand, the invention provides a pesticide drift-prevention spraying auxiliary agent for aerial pesticide application, which consists of the following components in percentage by mass:

further, the pesticide drift-prevention spraying assistant for aerial pesticide application consists of the following components in percentage by mass:

further, the pesticide drift-prevention spraying assistant for aerial pesticide application consists of the following components in percentage by mass:

further, the adhesive is methylated rapeseed oil and/or soybean lecithin.

Further, the emulsifier is one or more of fatty alcohol-polyoxyethylene ether, calcium dodecyl benzene sulfonate and potassium lauryl alcohol ether phosphate.

Preferably, the fatty alcohol-polyoxyethylene ether is one or more of undecyl alcohol polyoxyethylene ether, decyl alcohol polyoxyethylene ether and dodecyl alcohol polyoxyethylene ether.

Further, the wetting and penetrating agent is ethoxylated guerbet alcohol.

Further, the ethoxylated Guerbet alcohol is one or more of polyethoxylated butyl hexanol, polyethoxylated butyl heptanol and polyethoxylated butyl octanol.

Further, the synergist is virgin oleic acid.

The invention can effectively change the fog drop spectrum of the spraying liquid medicine, reduce the drift of the fog drops and increase the deposition rate and the adhesion effect of the fog drops through the synergistic action of the adhesive, the emulsifier, the synergist and the wetting and penetrating agent.

And (3) adding the adhesive, the emulsifier, the wetting agent, the penetrating agent and the synergist into a preparation tank according to the proportion at normal temperature and normal pressure, and fully and uniformly stirring by using a magnetic stirring device to obtain the pesticide drift-prevention spraying aid.

On the other hand, the invention also provides a using method of the pesticide anti-drift spraying assistant for aerial pesticide application, the spraying assistant is added into the prepared liquid medicine and uniformly stirred to prepare the aerial spraying liquid medicine, the prepared aerial spraying liquid medicine is added into the medicine box after being filtered and is sprayed within 2 hours, and the adding amount of the spraying assistant accounts for 0.25-1% of the total volume of the spraying liquid medicine.

Compared with the prior art, the invention has the following beneficial effects:

the auxiliary agent of the invention is mainly formed by mixing an adhesive, an emulsifier, a synergist and a wetting and penetrating agent in a specific ratio, wherein the adhesive is the main component. In the using process, the spraying auxiliary agent can change the fog drop spectrum of the spraying liquid medicine, reduce the drift of the fog drops and increase the deposition rate and the adhesion effect of the fog drops, thereby achieving the purposes of improving the effective utilization rate of the pesticide, reducing the environmental pollution and improving the control effect of plant diseases and insect pests.
