Embodiment 1

[0042]Formula: urea (particle size 1-3mm) 200kg, diflubenzuron (content 98%) 8.4kg, polyethylene glycol 6000 1.1kg.

[0043] Preparation:

[0044] (1) Polyethylene glycol 6000 is heated to 55-58°C in the liquid mixing tank. After the polyethylene glycol 6000 is completely dissolved, add diflubenzuron powder and mix for 10 minutes; the temperature of the above mixture is controlled at 55-58°C;

[0045] (2) Put urea into the fluidized granulator, turn on the fluidized granulator, transport the uniformly mixed drug in step (1) to the top nozzle of the fluidized granulator through the pipeline, open the valve, and spray; the drug meets the surface The urea particles with lower temperature are cooled rapidly to form a drug layer;

[0046] (3) Put the above-mentioned intermediate product after spraying into a horizontal mixer and continue mixing for 5 minutes before discharging; the drug is cooled to normal temperature (15-25° C.).

[0047] (4) Oscillating and screening the granul...

Embodiment 2

[0049] Formula: 200kg of urea (particle size 1-3mm), 8.8kg of diflubenzuron (content 98%), 0.5kg of biopheromone (cis-9-tridecene), 1.2kg of polyethylene glycol 6000.

[0050] Preparation:

[0051] (1) Polyethylene glycol 6000 is heated to 55-58°C in the liquid mixing tank. After the polyethylene glycol 6000 is completely dissolved, add diflubenzuron powder and cis-9-tridecene, and mix for 10 minutes; the above The temperature of the mixture is controlled at 55-58°C;

[0052] (2) Put urea into the fluidized granulator, turn on the fluidized granulator, transport the uniformly mixed drug in step (1) to the top nozzle of the fluidized granulator through the pipeline, open the valve, and spray; the drug meets the surface The urea particles with lower temperature are cooled rapidly to form a drug layer;

[0053] (3) Put the above-mentioned intermediate product after spraying into a horizontal mixer and continue mixing for 5 minutes before discharging; the drug is cooled to norma...

Embodiment 3

[0056] Formula: 800kg of urea (particle size 1-3mm), 35.0kg of diflubenzuron (content 98%), 10kg of polyethylene glycol 6000.

[0057] Preparation:

[0058] (1) First, put urea into a horizontal mixer. A heating pipe is provided in the interlayer of the outer wall of the mixer. Turn on the mixer, mix for 5 minutes, and heat the urea so that the temperature of the urea reaches 80°C;

[0059] (2) Add polyethylene glycol 6000 to the heated urea, keep the temperature at 80°C, and mix for 40 minutes;

[0060] (3) Add the diflubenzuron technical compound to the above-mentioned mixed urea, keep the temperature at 80°C, mix for 5 minutes, discharge, and cool to normal temperature (15-25°C).

[0061] (4) Oscillating and screening the granules, the selected diflubenzuron urea granules have a diameter of 1-4mm.

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...
