    NEW ENVIRONMENTALLY-FRIENDLY PESTICIDE REAGENT AND PREPARATION PROCEDURE
    TECHNICAL FIELD The present invention belongs to the technical field of pesticide reagents, and in particular relates to a novel environmentally friendly pesticide reagent and a method of preparing the same.
    BACKGROUND Currently, for the most recent prior art: As the climate of the planet changes, the phenomenon of various crops and forests affected by diseases, pests and weeds is becoming more and more serious. Pesticides are the basic production medium and play an important role in the control of diseases, pests and weeds. Pesticides can be used to suppress insects, fungi and other organisms that interfere with crop growth. Frequently used pesticides include trichlorfon, dichlorvos, dimethoate, omethoate, fenitrothion, phoxime, and phosmet. Frequently used fungicides include edible alcohol, thiophanate, carbendazim, tuzet, calcium polysulfide, and zineb. However, these frequently used insecticidal and bacteriostatic pesticides do not prevent disease in all plants, and some are even harmful to the growth and development of plants. Pesticides have good stability, can persist for a long time in the environment, and accumulate continuously in animals, plants and human bodies. As a result, pesticides were banned. Later, organophosphorus pesticides were used instead of the pesticides initially used. However, organophosphorus pesticides contained phosphorus, which easily caused eutrophication of aquatic organisms.
    At the same time, with the prolonged use of pesticides, the expansion of the scope, the increase in the use and abuse of pesticides, serious pollution affects the agro-ecological environment and excessive residues of harmful substances in agricultural products are produced, seriously threatening human health. The pesticide industry is a technology intensive industry. Current pesticide production technology is developing in the direction of high technology, automation and biotechnology. However, Chinese companies in the pesticide sector generally have small-scale production, relatively outdated equipment and technicality, and weak R&D capacities, lacking in competitiveness. Technical processes that are outdated or even prohibited are still used. A large amount of waste gas, waste water and waste slag is generated in all stages of production. The recovery rate of the product is low, the waste of resources is serious, the quality of pesticides is not high, and the surrounding environment is easily polluted.
    Currently, there are many varieties of pesticides, bacteriostatic agents and herbicides on the market. However, general pesticide formulations can only control certain types of diseases, pests and weeds, but long-term use of the same type of pesticide formulations can also lead to diseases, pests and diseases that generate resistance to them. pesticides. As people increasingly demand “green food” and “pollution-free food”, the commercial demand for environmentally friendly, non-polluting and naturally degradable pesticides is gradually increasing. From the perspective of the development of pesticide science, the "return to nature" and "non-polluting nature" of pesticides in the development and use of pesticides is an inevitable trend in the development of society and science. natural. Therefore, new formulations of bio-broad spectrum pesticides offer great prospects in terms of development and application.
    In summary, the problems existing in the prior art are as follows: (1) Existing insecticidal and bacteriostatic pesticides have no disease-preventing effect on all plants, and some are even detrimental to growth and disease. plant development.
    (2) Existing pesticide formulations have good stability, can persist for a long time in the environment, and accumulate continuously in animals, plants and human bodies, posing a serious threat to human health.
    (3) Existing pesticide formulations contain phosphorus, which easily causes eutrophication of aquatic organisms.
    (4) A large amount of waste gas, waste water and waste slag is generated in all stages of production. The recovery rate of the product is low, the waste of resources is serious, the quality of pesticides is not high, and the surrounding environment is easily polluted.
    (5) General pesticide formulations can only control certain types of diseases, pests and weeds, but long-term use of the same type of pesticide formulations can also lead to diseases, pests and resistance-generating diseases. pesticides.
