Description

Spraying auxiliary agent and application thereof

Technical Field

The invention relates to the technical field of agriculture, in particular to a spraying auxiliary agent and application thereof.

Background

At present, crop pest control is mainly chemical control, some large-scale crops such as rice, wheat and the like have the problem that ground walking machines are difficult to land for operation, and conventional spraying such as a manual sprayer and a stretcher-type sprayer is mainly used for control, so that pesticide is wasted, labor intensity is high, and pesticide application personnel and environment are seriously harmed. In recent years, with the development of science and technology, the aviation plant protection industry is rapidly developed, and particularly, the small agricultural unmanned aerial vehicle is applied, so that the operation efficiency is improved, and the prevention and control cost is reduced. The aviation plant protection has the advantages of wide application range, good effect, high efficiency, safety, convenience, medicine and water conservation and the like, but as a new technology, the aviation plant protection has short emergence time, so that the problems of easy volatilization, drift loss, loss on a target and the like of the droplets after the droplets are sprayed are solved. In order to solve the problems of easy volatilization, drift and the like of spray liquid in aviation pesticide application, the problems are mainly solved by adding a spray auxiliary agent at present, and most of aviation plant protection pesticide application selects some conventional spray auxiliary agents at present, but the problems of easy volatilization and easy drift of the spray liquid are still serious although some improvements are made on the original basis.

Crops grow in natural environment, the natural environment is not invariable, the difference of the hydrothermal conditions of the south and the north is great, and even in the same area, the crops have the difference of cold, hot, drought and waterlogging all the year round. The environment harmful to the growth of plants is called stress, the plants can form stress resistance, but the process is extremely long, and the method for enhancing the stress resistance of crops by adding substances outside is simple, quick and efficient.

The existing spraying auxiliary agent generally has a single function, mainly has one or more of functions of anti-drifting, anti-volatilization, facilitated atomization, surface tension reduction and the like, generally focuses on a certain stage of the whole action process of medicament atomization, sinking, absorption or conduction and the like, and has few spraying auxiliary agent products which play a role in the whole action process of the medicament. In particular, under adverse conditions, the function of the spray aid is limited and even phytotoxicity can occur.

CN109699640A discloses an unmanned aerial vehicle spraying smoke spraying auxiliary agent to solve conventional spraying and the problem that unmanned aerial vehicle spraying penetrability, breakdown nature are poor, solve the problem that current pesticide preparation is difficult to directly be applied to unmanned aerial vehicle spraying smoke spraying application, and solve add the problem that the compatibility of spraying smoke spraying auxiliary agent is poor, the stability is poor in the pesticide preparation. However, the problem that the spraying liquid is volatile and easy to drift still exists in the spraying process.

CN109430262A discloses a special adjuvant for flying prevention, which aims to solve the problems of easy evaporation and drift of fog drops, low sedimentation rate and the like in the existing unmanned aerial vehicle flying prevention and obviously enhance the adhesiveness, permeability and medicament absorptivity of the fog drops on the body surface of plants or pests, thereby ensuring the spraying efficiency and prevention and control effect of the plant protection flying prevention and application. But the improvement of the stress resistance of the plants is not very obvious.

CN107494530A discloses a high-efficiency permeability pesticide spray auxiliary agent, which is added with a strong cell activator and a growth promoting substance, and can promote photosynthesis of plants, improve stress resistance of crops, reduce phytotoxicity of methyl esterified soybean oil to the crops, enhance vitality and absorption capacity of the plants, effectively improve permeability of pesticides, promote absorption and utilization of the pesticides and improve application effects of the pesticides. But it is volatile and drifts during spraying.

Therefore, the development of a spraying aid with low volatility and low drift rate and capable of enhancing the stress resistance of crops is urgently needed in the field.
