Agricultural chemical able to be diffused along water surface in molecular mode

Abstract

A pesticide capable of evenly and stably distributed on the surface of water in its molecular state is disclosed. It can retain very high concentration and can reach the top of plant along stem. It is convenient to apply the pesticide by dripping instead of spraying. Meanwhile it has the characteristics of shooting pesticide to the insect on the leaves and inside the stem.

Description

technical field [0001] The invention relates to a pesticide for eliminating pests in agricultural production, in particular to a new pesticide dosage form which can make the active ingredients of the pesticide with a specific molecular structure diffuse and uniformly distribute along the water surface at high speed and climb along the stem of the plant. Background technique [0002] The water surface extensible pesticide formulation can float freely on the surface of the water body, and the active ingredients of the pesticide can effectively prevent and control harmful organisms living on the water surface or on the plants above the water surface through transpiration, penetration and conduction of the plants. Because it has special effects on harmful organisms living on or near the water surface compared with conventional preparations and application methods, many patents and papers on water surface floating agents have been published in Europe, America and Japan in recent y...

Problems solved by technology

If the active ingredient is water-soluble, it will gradually dissolve and disperse in the entire water body due to the concentration difference diffusion. However, in order to ensure the control effect on pests, the entire water body must reach a certain effective concentration, which causes waste. At the same time, it is extremely harmful to aquatic organisms, people, and animals and constitutes a hazard to the environment and ecology (pesticides have varying degrees of toxicity); if the active ingredients of the pesticide are insoluble or insoluble in water, the effective ingredients carried on the solid carrier It is extremely difficult for the ingredients to maintain an effective concentration and be evenly distributed in the water

4. It belongs to the film spreading oils of pesticides, in which the active ingredients are dissolved in solvent oil (which is also the carrier), and are generally insoluble in water. Its dispersion on the water surface depends entirely on the spreading of the carrier oil. To make it molecularly dispersed on the water surface, the only way to ensure the long-term stability of the carrier oil on the water surface is to consume a large amount of solvent oil, and it will also affect the reoxygenation of the water body and harm aquatic organisms; if the solvent oil is volatilized or cannot If it is stable for a long time, the active ingredients will crystallize and aggregate into solid particles due to their poor water solubility (or insolubility), and it is difficult to disperse evenly in molecular form, and it is also difficult to maintain the effective concentration in water

[0008] According to relevant information, there are no reports about pesticide preparations that can make the active ingredients of pesticides diffuse along the water surface at high speed in the form of molecules.
