Embodiment 1

[0048] 1. This embodiment provides a special spray additive for agricultural plant protection drones. The spray aid is composed of the following components: methyl oleate 75.5%, organic phosphate 2%, fatty alcohol polyoxyethylene ether 3.5%, sorbitan fatty acid ester 8.5%, polyoxyethylene sorbitan fat Ester 3.5%, n-butanol 7%.

[0049] The preparation method of the special auxiliary agent: according to the formula of the spray auxiliary agent, weigh methyl oleate, organic phosphate, fatty alcohol polyoxyethylene ether, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester After mixing n-butanol, use a shear homogenizer to shear at a rate of 2000 rpm for 10 minutes to form a uniform and transparent special additive for anti-flying spray. The mixing ratio of this additive and water is 1:0.667.

Abstract

The invention discloses an air control spray additive as well as a preparation method and an application thereof and belongs to the technical field of pesticide preparations and pesticide application.The air control spray additive comprises 70-94% of plant oil, 5-20% of an emulsifier and 1-10% of a co-emulsifier in percentage by mass; during preparation of a spray liquid, the additive is mixed with a pesticide and water, wherein the oil and water form an emulsion (turbid) liquid in the water-in-oil form under an effect of the emulsifier and the co-emulsifier; active ingredients in the pesticide preparation are uniformly dispersed in oil phase or water phase of oil-based emulsion (turbid) liquid, and is sprayed by using a hydraulic or centrifugal nozzle to form water-in-oil fog drops withmedium particle sizes; therefore, the influence of excessive oil on leaf surfaces of crops is reduced; the fog drops rapidly spread during moving to the surfaces of plants so that the interference ofa wind field generated by rotors of an unmanned aerial vehicle to settlement and adhesion behaviors of the fog drops can be obviously reduced; after water is added, the water-in-oil emulsion liquid isformed to improve the specific weight of the additive, accelerate the settlement of the fog drops and reduce the drifting of the fog drops.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation and pesticide application, in particular to a spray adjuvant for fly control and its preparation method and application. Background technique [0002] At present, my country's agricultural field is facing a serious shortage of labor force, which greatly limits the production and development of agriculture, and the cost of agricultural production is increasing year by year. The use of drones for plant protection flying anti-spraying has greatly improved the work efficiency of crop diseases, insect pests and weeds, and has a wide range of applications. It can also spray pesticides freely in complex terrain and save labor. It can not only effectively alleviate the problem of rural labor shortage. And it has a great role in promoting the development of agricultural mechanization and intelligence. [0003] In recent years, with the development of drone technology, the application of dron...
