Benefits of technology

This new type of pesticides has several benefits compared to traditional chemical methods that use harmful substances like chlorsone oil for their purpose. These improvements include improved safety by reducing environmental concerns associated with these compounds while still delivering effective control over weed infestation without causing any negative side effects on crops grown therein. Additionally, this technology allows for easy mixing between different types of fertilizers at once when producing certain products such as tablets containing pills made from calcium carbonate instead of expensive raw materials. Overall, it provides an efficient way to produce high quality agrochemically active ingredients efficiently and safely through various processes.

Problems solved by technology

This patented technical problem addressed in the patents relates to improving the compatibility between different types of pesticidal agents (such as pyridaben) while maintaining their ability for rapid release when applied through various methods such as broadcast or drip irrigation systems without causing environmental harm.

Abstract

The invention discloses herbicide fertilizer granules and a method for preparing the same. The granules mainly comprise the following components in percentage by weight: 0.1 to 0.3 percent of butachlor, 0.01 to 3 percent of bensulfuron, 5 to 20 percent of coating agent, 6 to 15 percent of adhesives and 59 to 88 percent of NPK compound fertilizer, wherein the active ingredients of the NPK compoundfertilizer accounts for 25 to 52.8 percent of total weight of the fertilizer granules, and the coating agent is soft clay or low-grade celatom. The method for preparing the granules comprises the following steps of: mixing the adhesives with the NPK compound fertilizer and granulating the mixtures with a granulator; dissolving the butachlor and the bensulfuron in organic solvents and diluting thesolution; spraying the diluted solution onto the surface of the granules; coating the granules with the coating agent; and screening the granules to prepare the granules with a grain diameter between1.0 and 4.75mm. The granules have the advantages of low production cost, no pollution, harm or smell, strong adsorption capacity, excellent release effect, no environmental pollution, double functions of weeding and improving utilization rate of fertilizer efficiency, and capacity of controlling annual weed growth in seedlings-throwing fields of paddy rice.
