Description
Technical Field
The application belongs to the technical field of special pesticide fertilizers, and particularly relates to a clothianidin special pesticide fertilizer and a preparation method thereof.
Background
The pesticide fertilizer is a novel special pesticide fertilizer formed by mixing a pesticide and a fertilizer according to a certain proportion formula and stabilizing the fertilizer and the pesticide in a specific composite system through a certain process technology, and the pesticide fertilizer is divided into a chemical pesticide fertilizer and a biological pesticide fertilizer from the effective components; the control objects are divided into insecticide fertilizers, bactericide fertilizers, herbicide fertilizers, plant regulator fertilizers and the like; the preparation form is divided into solid pesticide fertilizer and liquid pesticide fertilizer. The solid pesticide fertilizer is divided into inert brick residue pesticide fertilizer, large fertilizer pesticide fertilizer and biological stimulin special pesticide fertilizer. The mutual promotion and synergism mechanism of the pesticide and the fertilizer is generally as follows: the pesticide can effectively prevent and control crop diseases and insect pests, promotes the crops to absorb and utilize nutrient substances, and in turn, the crops can effectively absorb and utilize the nutrient components of the fertilizer to improve the capability of the crops in resisting the diseases and insect pests, and the pesticide and the fertilizer mutually promote synergism to promote the healthy growth of the crops.
Pesticide granules (granules, GR) have a long history as one of pesticide formulations, but the traditional brick slag pesticide granules have certain disadvantages due to the fact that brick slag carriers are used for loading pesticide components: firstly, the brick slag carrier has no fertilizer effect and is difficult to degrade; and secondly, the excessive application of brick slag pesticide fertilizer can cause the air permeability of the soil to be too strong and reduce the water retention and soil moisture conservation performance of the soil. Particularly, in recent years, China pays high attention to the soil health problem, preparations are urgently needed to solve the problem, and special medical fertilizers serving as GR branches are different from military projections in recent years and become new medical fertilizer markets. The special pesticide fertilizer is characterized by being rich in biostimulant and having a soil conditioning function, well accords with application scenes of broadcasting, furrow application and hole application in the planting of farmers, can effectively improve the soil while preventing and treating plant diseases and insect pests, increase the content of organic matters in the soil, preserve water, fertilizer and moisture, increase the air permeability of the soil, fix nitrogen, dissolve phosphorus and adsorb potassium, improve the absorption and utilization rate of the fertilizer in the soil, improve the quality and the price-overflowing capacity of agricultural products, is remarkable in the foreigners and occupies an important share of the market.
Clothianidin, as a classical second-generation nicotine compound, is a high-efficiency pesticide with contact poisoning, stomach toxicity and systemic uploading conduction activity, has a wide insecticidal spectrum, and is effective on piercing-sucking mouthpart pests, such as aphids, wireworms, grubs, thrips, liriomyza, garlic maggots, flea beetles and the like of various field crops and crops. Because the solubility in water is moderate in a series of nicotine compounds (20 ℃, 0.304g/L), the pesticide is resistant to leaching in soil, is particularly suitable for application scenes of underground pesticide fertilizers, can replace high-toxicity organophosphorus pesticides on the market, and has huge market potential. However, the pesticide effect of the existing pesticide formulation of clothianidin is required to be improved for lasting and slow release.
