Description
Technical Field
The invention relates to a plant protein source film-forming pesticide adjuvant, a preparation method and application thereof, and belongs to the technical field of pesticide adjuvants.
Background
To the knowledge of the applicant, the conventional pesticide spray adjuvant compositions are under question whether they are environmentally safe or ecologically safe, and in addition, have inherent drawbacks such as: (1) although the application of the auxiliary agent can reduce the dosage of the pesticide and the cost of the pesticide, the price of the domestic pesticide preparation is lower, and even if the auxiliary agent is applied to reduce the cost, farmers can hardly buy the auxiliary agent with extra money. (2) The liquid spraying amount of cultivated land per hectare in China is too high, and the economic benefit brought by the aid is weakened. The amount of some of the adjuvants used is proportional to the amount of liquid spray, typically from 0.125% to 1% of the amount of liquid spray, and since such proportions exist, higher amounts of liquid spray naturally increase the cost of application of the adjuvant per hectare. Meanwhile, the high liquid injection amount can reduce the synergistic effect of the auxiliary agent at some times. (3) Few researches on the auxiliary agents are carried out in China, and the auxiliary agents are single in variety. In late eighty and early ninety years, most of the nonionic surfactant herbicide adjuvants popularized in China use ethanol as a solvent, such as YZ-901, AA-921 and the like, and have a synergistic effect on pesticides in a certain humidity range, but the synergistic effect is not obvious under a drought condition.
The applicant of the invention gradually confirms the advantages of the film-forming pesticide adjuvant in practical research, and then carries out a great deal of research on the film-forming pesticide adjuvant. In the investigation, the applicant of the invention considers that the plant protein may have the prospect of being used as a film-forming pesticide auxiliary component, but further research is needed to know whether the plant protein source film-forming pesticide auxiliary can be successfully developed.
According to the characteristics of proteins that can function, their functional properties can be divided into 3 major categories: (1) water and properties, depending on the interaction between the protein and water, including water adsorption and retention, wettability, swellability, adhesion, dispersibility, and solubility, etc.; (2) structural properties, which are properties associated with interactions between protein molecules, such as precipitation, gelation, organization, dough formation, and the like; (3) the surface properties of proteins, which relate to the action of proteins between two phases of different polarity, are mainly the foaming and emulsifying properties of proteins. In addition, some people have classified the functional characteristics of protein into a fourth property, namely, organoleptic properties, which relate to the turbidity, color, flavor combination, chewiness, smoothness and the like of the protein in food according to the functions of the protein in the food organoleptic quality. These functional properties of proteins are not independent and completely different, and there is also a correlation between them, for example, protein gelation involves both the interaction of protein molecules (formation of a spatial three-dimensional network) and the interaction of protein molecules with water molecules (retention of water); viscosity and solubility are related to the interaction between proteins.
