Problems solved by technology

The medicinal fertilizer granule is a one-time insecticide for vegetables, wheat, rice, etc. Since polyvinyl alcohol or gum arabic is used as a sustained-release agent, the disadvantages are: 1. Polyvinyl alcohol is highly toxic; gum arabic is weakly alkaline, high market price
2. Polyvinyl alcohol and gum arabic are not easy to decompose in the soil, causing soil compaction and polluting the soil

Abstract

The invention relates to a pesticide and fertilizer mixing particle agent for controlling soil insects, which has the advantages of low cost, no pollution, no peculiar smell, strong absorption capability, good release effect, prevention of water and soil loss, control of underground insects, and enhancement of utilization rate of fertilizer efficiency, and is suitable for leek, corn, peanut and soybean. The mixing particle agent contains the following raw materials based on the total weight: 0.1%-10% of chlorpyrifos, 5%-20% of coating agent, 6%-15% of adhesive, 6%-10% of dispersant, and 45%-80% of NPK compound fertilizer, wherein the NPK compound fertilizer accounts for 25%-60% of the total weight of the medicine and fertilizer mixing particle agent; the coating agent is light-weight clay or low-grade diatomite; the dispersant is calcium dodecyl benzene sulfonate; and the adhesive is clay, dextrin or the mixture of the clay and the dextrin. The production method is characterized in that the adhesive, the dispersant and the NPK compound fertilizer are mixed and granulated by a granulator; the chlorpyrifos is dissolved in vegetable oil or organic solvent, diluted, uniformly sprayed to the surface of the prepared particle, coated by the coating agent, and sieved, and then the particle agent with the diameter of 1.0-4.75mm is prepared.

Description

technical field [0001] The invention relates to a medicine-fertilizer mixed granule for controlling underground pests. Background technique [0002] Chlorpyrifos is a cholinesterase inhibitor, which has contact killing, stomach poisoning and fumigation effects, and can effectively kill cutworms, grubs, mole crickets, needleworms, flea beetle eggs and other parasitic pests in the soil. Because its residual period on the leaves is not long, but its residual period in the soil is longer, so it has a better control effect on underground pests. However, in actual use, chlorpyrifos is often added to soil or mixed with sand, and then mixed with compound fertilizer (or urea), which is very troublesome in operation and wastes labor. [0003] In CN101318866, "a medicine fertilizer granule" is mentioned, and its raw material composition and content are: based on the total weight of the medicine fertilizer granule, the content of chlorpyrifos is 0.1% to 30%; , P content 1% to 15%, K c...
