Embodiment Construction

[0041] Non-limiting examples are described as follows:

[0042] A. Kasugamycin water dispersible granules (WDG)

[0043] 1. Take 3.6kg of 65% kasugamycin original drug, 5kg of wetting agent SOPA, 0.8kg of disintegrating agent NNO, 2kg of disintegrating agent ammonium sulfate, 1kg of binder carboxymethyl cellulose, 2kg of stabilizer BHT, and 76.4kg of filler Taogui , after mixing, jet milling, adding 20kg of water, mixing, kneading, granulating, drying, and sieving to obtain fenoxystrobin water-dispersible granules. Or go through wet sanding, drying, granulation, drying and sieving to get kasugamycin WDG.

[0044] 2. Take 9.2kg of 65% kasugamycin technical, 3kg of wetting agent teaku, 2kg of opening powder, 10kg of disintegrating agent sodium lignosulfonate, 4kg of disintegrating agent calcium chloride, 1.5kg of binder starch, stable Agent tributyl phosphate 1kg, filler white carbon black 15kg, kaolin 48.7kg, obtain kasugamycin WDG by the example 1 preparation method.

Abstract

The invention discloses a kasugamycin water dispersible granule, which is a granular obtained by mixing processing of kasugamycin, an auxiliary agent and a filler, and can be quickly disintegrated and dispersed in water to form a high-suspension and steady dispersion system. The kasugamycin water dispersible granule has no powder drift during production, use and packaging processes, is safe to operators, and does not pollute the environment; and compared with wettable powder, the kasugamycin water dispersible granule has large density and small volume, can greatly reduce the cost for packaging and storage, and is also convenient to recover packaging materials. The kasugamycin water dispersible granule particularly has remarkable drug effect on cucumber wilt and rice blast. The preparation has good dispersivity and high suspension rate in the water, and can improve control effect.

Description

technical field [0001] The invention relates to a new formulation of an agricultural fungicide, in particular to a preparation of the fungicide kasugamycin, that is, a kasugamycin water-dispersible granule (WDG). Background technique [0002] Traditional pesticide formulations such as emulsifiable concentrates, powders and wettable powders account for about 80% of the total formulations in my country. With the development of processed formulations, the shortcomings of traditional formulations have become more prominent. The emulsifiable concentrate contains a large amount of organic solvents such as xylene and toluene, which not only causes serious pollution to the environment, but also wastes petrochemical resources. Due to its very fine particle size, wettable powder often produces flying dust during production and use, which not only endangers people's health, but also causes environmental pollution. A small amount of flying dust can easily cause phytotoxicity to crops. ...
