Spray additive and application thereof

Abstract

The invention relates to a spray additive and application thereof. The spray additive comprises the following components: plant essential oil, ketone compounds and a solvent. The spray additive provided by the invention has synergistic and yield-increasing effects, is suitable for unmanned aerial vehicle spraying or large mechanical spraying, is low in volatilization rate, good in spreadability, good in permeability, low in drift rate and high in settling rate, has the effect of enhancing the stress resistance of crops, and is good in insecticidal and bactericidal effects.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a spray auxiliary and its application. Background technique [0002] At present, the control of crop diseases and insect pests is mainly based on chemical control. Some large-scale planted crops such as rice and wheat have the problem that ground walking equipment is difficult to work in the field. Conventional sprayers such as manual sprayers and stretcher sprayers are mainly used for prevention and control. , not only waste pesticides, labor intensity is also very large, but also cause serious harm to pesticide applicators and the environment. In recent years, with the development of science and technology, the aviation plant protection industry has developed rapidly, especially the application of small agricultural drones, which not only improves the operation efficiency, but also reduces the cost of prevention and control. Aviation plant protection has the advantages of ...

Problems solved by technology

[0004] Existing spray auxiliaries usually have a single function, mainly have one or several functions in anti-drift, anti-volatility, atomization, and surface tension reduction, and usually focus on agent atomization, sinking, absorption or conduction Waiting for a certain stage of the whole action process, there are very few spray adjuvant products that play a role in the entire action process of the medicament

Especially under adversity conditions, the function of spray auxiliaries is limited, and even cause phytotoxicity

[0005] CN109699640A discloses an adjuvant for unmanned aerial vehicle smoke spraying, to solve the problems of conventional spray and unmanned aerial vehicle spraying penetration and poor penetration, and to solve the problem that existing pesticide preparations are difficult to be directly applied to unmanned aerial vehicle spraying spraying problems, and to solve the problems of poor compatibility and poor stability of adding fume spray auxiliaries to pesticide preparations

However, during the spraying process, there are still problems that the spray liquid is volatile and easy to drift

[0006] CN109430262A discloses a special auxiliary agent for flying defense, to solve the problems of easy evaporation, drifting and low sedimentation rate of fog droplets in the flying defense of existing drones, and significantly enhance the adhesion of fog droplets on the surface of plants or pests, Penetration and chemical absorption rate, so as to ensure the spray efficiency and control effect of plant protection aerial control pesticide application

However, it is volatile and drifts in the process of spraying
