Caricidal composition containing bromopropylate and diafenthiuron

Abstract

The invention discloses a miticide composite containing fenisobromolate and diafenthiuron, and relates to a pesticide composite, in particular to the pesticide composite used for killing acarids agriculturally. The active ingredient of the pesticide composite used for killing acarids is the mixture of the fenisobromolate and the diafenthiuron. The weight ratio between the fenisobromolate and the diafenthiuron is 1:10 or 10:1, the weight percentage of the active ingredient is 1-80%, and suspending agent can be prepared by adopting the method of universal preparation according to the actual needs. The fenisobromolate and the diafenthiuron are selected as the active ingredients of the miticide composite, the formulation is reasonable, so that the deficiencies of strong fastness of diafenthiuron, high controlling cost caused by a large quantity of usage and low acaricidalactivity of the fenisobromolate are made up, and the synergy is remarkable. The experiments proves that the miticide composite can quickly kill the acarids, the effects can last for a long time, the yield and quality of the crops are guaranteed while the controlling effect is ensured, and the miticide composite can meet the needs of agricultural industry at present.

Description

technical field

[0001] The invention relates to a pesticide composition, in particular to an acaricidal composition containing bromofen-methyl and diafenthiuron used in agriculture. Background technique

[0002] Mites, commonly known as red spiders, are a serious hazard in agriculture. The conventional pesticides currently used for prevention and control are prone to resistance due to repeated use, and the cost of prevention is also high;

[0003] Bromopropylate, (bromopropylate) chemical name: 4,4'-dibromobenzoic acid isopropyl ester, structural formula is:

[0004]

[0005] The compound is an acaricide with broad acaricidal spectrum, long duration, low toxicity and relatively safe to natural enemies, bees and crops. Strong contact, non-systemic, have a certain killing effect on adults, nymphs and eggs. Temperature changes have little effect on efficacy. The drug is suitable for crops such as cotton, fruit trees, vegetables and tea, and can prevent and control various...
