Diflubenzuron urea granule and preparation method thereof

Abstract

The invention provides a diflubenzuron urea granule and a preparation method thereof. The invention is to solve the problems that cyromazine is always used to control and kill fly maggots; no pesticide with same effect can be alternated; pesticide resistance is easily generated; and a conventional diflubenzuron suspension is not applicable to killing the fly maggots in manure of livestock and poultry. The diflubenzuron urea granule provided by the invention uses urea as a carrier and a core, and has the outer layer adhered with a pesticide namely diflubenzuron. The diflubenzuron urea granule is directly subjected to dry spreading into the manure of the livestock and the poultry to control and kill the fly maggots, can slowly sink into the manure and diffuse due to heaviness of the granules, and has better effect to control the fly maggots located at the deep position of the manure; meanwhile, through dry spreading for use, no stress is generated to the livestock and the poultry; no irritation is generated to respiratory tracts of the livestock and the poultry; the content of urea in the manure can be increased; and the fertilizer efficiency of the manure is improved.

Description

technical field [0001] The invention relates to diflubenzuron urea granules and a preparation method thereof, belonging to the field of veterinary medicine and its manufacture. Background technique [0002] The concept that green water and green mountains are golden mountains and silver mountains has penetrated the whole society. People have higher and higher requirements for the livestock and poultry breeding environment, but flies and fly maggots have always been a major problem that plagues farms. At present, the drugs used to control the fly maggots in livestock and poultry manure mainly include traditional insecticides such as organophosphorus, amitraz and pyrethroid insecticides, and the insect growth regulator cyromazine. However, the use of traditional insecticides to control fly maggots in livestock and poultry manure has some disadvantages: for example, organophosphorus insecticides and amitraz are highly toxic and have high drug residues, and there is a risk of p...

AI Technical Summary

Problems solved by technology

However, the suspension is not suitable for the spraying control of fly maggots in livestock and poultry farms, because the spray administration in the livestock and poultry house will cause the stress of the livestock and poultry to cause the production performance to decline, and it will also induce diseases of the respiratory tract of livestock and poultry; septic tank or The effect of using diflubenzuron in the spraying area where the feces gather is not ideal. The light drug will float on the surface of the feces, and it will not be effective on the fly maggots living in the deep part of the feces.
