Embodiment 1

[0025] A dispersible granule for agricultural water containing flufenoxuron, which is composed of the following components by weight percentage: flufenoxuron 25%, pyraclostrobin 1%, dispersant 2.5%, wetting agent 10%, disintegrant 3%, polymer Ethylene glycol 2%, ammonium sulfate 15%, and fillers to 100%.

[0026] A preparation method of agricultural water dispersible granules containing flufenoxuron includes the following steps:

[0027] (1) Weigh according to the above weight ratio;

[0028] (2) Airflow pulverization of flufenoxuron and pyripin, together with dispersant, wetting agent and disintegrant, to obtain the required particle size;

[0029] (3) Add polyethylene glycol and other additives to obtain granulation materials;

[0030] (4) The granulation material is quantitatively fed into the fluidized bed granulation dryer, after granulation and drying, water dispersible granules are obtained.

Abstract

The invention relates to an insecticide and particularly relates to agricultural water dispersible granules containing flufenoxuron and a preparation method of the agricultural water dispersible granules. The agricultural water dispersible granules are prepared from components in percentage by weight as follows: 2%-60% of flufenoxuron, 1%-5% of fenitrothion, 1%-10% of a dispersant, 2%-10% of a wetting agent, 1%-5% of a disintegrating agent, 0.1%-5% of polyethylene glycol, 10%-20% of ammonium sulfate and the balance of filler. The agricultural water dispersible granules have stable quality, aregood in dispersity, have a very good control effect on mites such as red spider mite and the like, have high insecticidal speed and long lasting period and can control multiple mites after being applied once, the pesticide use cost is reduced, and the toxicity of the pesticide is also relieved.

Description

Technical field [0001] The invention relates to pesticides, in particular to a dispersible granule for agricultural water containing flufenoxuron and a preparation method thereof. Background technique [0002] Fipronil inhibits the formation of chitin, so that pests cannot molting and metamorphoses and die, especially to control the normal molting and development of larvae to achieve the purpose of killing insects. With foliar retention, it can be used to control mites and insects in the immature stage of citrus, cotton, vegetables, soybeans, fruit trees, corn and other crops. It is safe to predatory mites and insects. At present, flufenoxuron is the only acylurea insecticide that can cure both insects and mites, has good efficacy, and has a long residual effect. In the present invention, the pyridoxine is added to prepare agricultural water dispersible granules, which has stable quality and good dispersibility, and has better control of red spiders and other mites. Summary of ...
