Problems solved by technology

Although water-suspension concentrates are environmentally friendly preparations, they have high requirements for production conditions, and high-content preparations are impossible. The cost of production, packaging and transportation is high, resulting in increased use costs; wettable powders are seriously polluted by dust during processing and use. Harmful to human health

Abstract

The invention relates to an agricultural acaricide, in particular to a spirodiclofen water dispersible granule and a preparation method thereof. The water dispersible granule is a regular or irregularThe invention relates to an agricultural acaricide, in particular to a spirodiclofen water dispersible granule and a preparation method thereof. The water dispersible granule is a regular or irregular granule developed based on wettable powder and a water suspending agent. The water dispersible granule overcomes the defects of emulsifiable solution, the wettable powder and the water suspending agegranule developed based on wettable powder and a water suspending agent. The water dispersible granule overcomes the defects of emulsifiable solution, the wettable powder and the water suspending agent and auxiliary agents with different components are added to the formula. The implementation effect shows that the spirodiclofen water dispersible granule has good dispersibility, indefinitely suspent and auxiliary agents with different components are added to the formula. The implementation effect shows that the spirodiclofen water dispersible granule has good dispersibility, indefinitely suspended working substances, fast disintegration speed with the disintegration time less than 3 min and good hot storage stability.nded working substances, fast disintegration speed with the disintegration time less than 3 min and good hot storage stability.

Description

technical field [0001] The invention relates to a pesticide acaricide, in particular to a spirodiclofen water-dispersible granule and a preparation method thereof. technical background [0002] At present, there are many agricultural acaricides, and spirodiclofen is one of them. It is a miticide with a new mechanism of action developed by Bayer CropScience for many years. It inhibits the fat synthesis in the body of harmful mites and destroys the energy metabolism of mites, thereby killing mites. Its acaricide mechanism is completely different from the existing various acaricides, so there is no cross-resistance problem with other existing acaricides, and it can be used to control a variety of resistant spider mites. In 2003, the product was first launched in Brazil, South America, to prevent and control citrus spider mites. In that year, 45,000 liters of preparations were sold. By 2005, it had rapidly grown into the largest acaricide in the Brazilian citrus market. Spiro...
