Abstract

The invention relates to an insecticidal emulsion in water containing natural celastrus angulatus and natural vitex negundo. The emulsion in water consists of 1wt%-12wt% of an active component and the balance of assistants. The active component is an insecticidal composition containing natural celastrus angulatus and natural vitex negundo by the weight ratio of (1-12): (1-12). The natural celastrus angulatus and natural vitex negundo in the composition are natural active products extracted from plants. The natural celastrus angulatus and natural vitex negundo, namely two insecticidal substances from plant sources, are mixed to obtain the biopesticide with high efficiency, low toxicity and slight environmental pollution. The production cost of the emulsion in water is low and the raw materials are easily available. The insecticidal emulsion is good in insecticidal effect and low in medical cost, has a remarkable synergistic effect, and can delay generation of pest resistance to insecticide. The insecticidal emulsion in water provided by the invention has a better control effect on aphid injurious insects.

Description

technical field [0001] The invention relates to a pesticide and insecticide composition, in particular to a compound pesticide and insecticide composition containing natural picroderm, which belongs to the technical field of pesticides and insecticides. Background technique [0002] Discovering compounds with pesticide activity from natural products is one of the effective ways to develop new insecticides and overcome or delay the development of pesticide resistance in pests. Plants are a treasure house of natural active compounds. A wide variety of secondary metabolites are formed by plants to resist adversity in the long-term competition for survival. Most of them have certain biological regulation effects on harmful organisms such as diseases, insects, and weeds. Researches at home and abroad have shown that the active substances of botanical pesticides have a novel mode of action on harmful organisms, a unique mechanism of action, and it is easy to discover new molecular...
