Abstract

The invention discloses a Pyrifluquinazon and bistrifluron compound composition, the effective ingredients of the compound composition are Pyrifluquinazon and bistrifluron, and the weight percentage of the Pyrifluquinazon and the bistrifluron in the compound composition is (5-50):(50-5), preferably (5-20):(40-5). The dosage forms which can be prepared by the composition are emulsion in water, water dispersible granules, microemulsion, a suspending agent, wet powder and missible oil, and the total weight of the Pyrifluquinazon and the bistrifluron in the dosage forms rakes up 5%-80% of the total weight of the whole preparation, preferably 10%-60%. According to the composition, the mechanisms of action are different, the synergistic effect is remarkable after compounding, the pest resistance to insecticide is delayed, the insecticidal spectrum is widened, particularly importantly the effective drug dose per unit area is significantly reduced, the pesticide residue is reduced, and the pesticide pollution is alleviated.

Description

technical field [0001] The invention relates to the compounding of pesticides, in particular to a compounding composition of Pyrifluquinazon and bistrififluben. Background technique [0002] Pyrifluquinazon is an insecticide with bisamide structure invented by Japan Pesticide Company and jointly developed by Japan Combination Chemical Company. It applied for a patent in 2000. The agent is effective against pests of the family Curlyidae, and is more effective against aphids, whiteflies, clams, leafhoppers and thrips. It is registered for greenhouse ornamental crops to prevent and control sucking pests such as aphids, forage insects, and whiteflies. etc.; given the high activity of this agent against pests known to be less susceptible to insecticides, it can be used in insecticide resistance management by causing the pests to stop feeding and starve; the product prevents Plant tissue suffers more damage while limiting the spread of some important diseases. The structural for...
