Tricyclazole water suspending agent composition

Abstract

The invention relates to tricyclazole water suspending agent composition. The tricyclazole water suspending agent composition is prepared from, by mass percent, 40-70 parts of tricyclazole active compound, 2-10% of wetting dispersant, 0.3-1.0% of crystallization inhibitor, and allowance of deionized water. The tricyclazole water suspending agent composition can effectively solve the technical difficulty of ostwald ripening existed in the high-content suspending agent proceed by tricyclazole active compound, and a problem of poor storage stability of the water suspending agent product with high content of tricyclazole. Meanwhile, the formula also can solve the problems of big viscosity, poor mobility, low processing efficiency, and others caused by high solid content of the product when the high-content suspending agent product is processed.

Description

technical field [0001] The invention relates to a tricyclazole water suspension composition and belongs to the technical field of pesticides. Background technique [0002] Tricyclazole, also known as clemenazole, clemenazole, biyan, and rice blastazole, is a protective triazole fungicide with strong systemic properties. It has special effects in preventing and treating rice blast. The roots, stems, and leaves of rice can absorb it and transport it in the plant. Spraying it once or twice during the entire growth period of rice can effectively prevent the occurrence of rice blast. Tricyclazole has strong anti-scouring ability, and it does not need to be re-sprayed in case of rain after 1 hour of spraying. It mainly inhibits spore germination and episporium formation, thereby effectively preventing the invasion of pathogens and reducing the production of spores of Magnaporthe grisea. Tricyclazole has strong systemic and transport properties, and it decomposes slowly in the pl...

Problems solved by technology

However, since the solubility of tricyclazole in water has reached 1.6g / L, it is a species with relatively high solubility in water. The processed suspension product will undergo Ostwald aging during storage, resulting in the crystallization of the product. The small particles aggregate and grow, and the particle size becomes larger, resulting in a decrease in drug efficacy. Products with high content of suspending agent may even be unusable due to the hardening of the material due to Austenitic ripening.

Therefore, the suspending agent products in the current market are mostly products with low content of 20~30%, and its content determines its large dosage and high packaging and transportation costs, which also reduces its advantages over wettable powder and granule products.
