Abstract

The invention belongs to the field of pesticide compound composite, in particular relates to a compound composite containing penconazole. The invention provides a compound composite containing penconazole, aiming at expanding the control scope, improving the control effect and reducing the dosage of pesticide and the agricultural cost by compounding. The technical scheme is as follows: active ingredients of the compound composite containing penconazole comprise A and B, and the weight ratio of A and B is (40:1)-(1:40), wherein A is penconzole, and B is one or more of difenoconazole, epoxiconazole and hexaconazole. Weight percent of the active ingredients A and B in the compound composite is 1-90%. The invention has the beneficial effects that firstly, products can show extremely good synergism effect on multiple diseases in a certain matching range; and secondly, the sterilization spectrum can be expanded by reasonable compounding, and the disease control range can be widened.

Description

technical field [0001] The invention belongs to the field of pesticide compound compositions, in particular to a compound composition containing penconazole. Background technique [0002] Penconazole, the chemical name is: 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2-methyl]-1-hydrogen-1, 2,4-Triazoles, belonging to the triazine heterocyclic fungicides (triazole fungicides), are sterol demethylation inhibitors, which act during fungal spore germination and invasion, through the roots, stems, and leaves of crops It can be absorbed by other active tissues, and can quickly conduct upwards with body fluids in the plant body. Penconazole has the functions of treatment, protection and eradication. It is mainly used to prevent and control the pathogens of powdery mildew family, black star fungus and other pathogenic sporophytes, basidiomycetes and half-knowledge fungi on a variety of fruit trees, vegetables and ornamental plants, especially pome fruit trees , pumpkins, gra...
