Phosethyl-aluminum water dispersible granules and preparation method thereof

Abstract

The invention discloses 80 percent phosethyl-aluminum water dispersible granules. The granules consist of the following components in percentage by weight: 85 to 87 percent of 95 percent phosethyl-aluminum raw drug, 2 to 5 percent of 50 percent alkyl glycoside, 2 to 5 percent of dodecyl dimethyl betaine, 1 to 5 percent of binder gum Arabic, and 5 to 10 percent of filler ammonium sulfate or urea. The preparation method comprises the following steps: uniformly mixing the raw materials, crushing, mixing with water, granulating, and drying to obtain the 80 percent phosethyl-aluminum water dispersible granules. The 80 percent phosethyl-aluminum water dispersible granules have long pesticide effect time and few application times to crops, a fertilizer is applied to the crops while insects and diseases of crops are prevented and controlled, and the crops can absorb nutrition to facilitate growth.

Description

technical field [0001] The invention relates to a water-dispersible granule (WGD) of aluminum triethylphosphonate and a preparation method thereof. Background technique [0002] Aluminum triethylphosphonate, common name: aluminum ethylphosphonate, chemical name: aluminum tris(O-ethylphosphonate), molecular weight: 354, the technical name of aluminum triethylphosphonate is white powder, colorless and odorless. Aluminum triethylphosphonate is an excellent new organophosphorus fungicide with high efficiency, broad spectrum and safety. It mainly prevents diseases caused by downy mildew and Phytophthora in fruit trees, vegetables and other economic crops. Aluminum triethylphosphonate fungicide was first developed by Rhône-Planck in France. It has a long production history in my country. Many manufacturers produce aluminum triethylphosphonate. The current annual production capacity of the original medicine has reached more than 10,000 tons. More than 80% are processed into prepara...

AI Technical Summary

Problems solved by technology

However, the preparation products have a single dosage form, mainly 80% aluminum triethylphosphonate wettable powder (WP) and 90% aluminum triethylphosphonate soluble powder (SP)

Due to the characteristics of easy moisture absorption and low density of aluminum triethylphosphonate, it brings certain pollution to personnel and the environment in the process of production, processing, packaging and transportation, and application of pesticides. Long-term storage of products will cause caking and deterioration, resulting in quality problem arises
