[0033] 2. Biological Activity Determination and Drug Efficacy Test Example

[0034] Combining the active ingredients of different pesticides to make pesticides is an effective and fast way to develop and develop new pesticides and prevent and control resistant pests in agriculture. When pesticides of different varieties are mixed, they usually show three types of effects: additive effect, synergistic effect and antagonistic effect. However, the specific effect cannot be pre...

Abstract

The invention discloses an agricultural pesticide. The active components are afidopyropen and pymetrozine at a mass ratio of 1:80-80:1. The composition possesses excellent synergistic effect, the insecticidal activity is better than that of single components, and excellent prevention and controlling effect on a plurality of pests such as rice planthopper, powdery mildew, corn borer, cotton bollworm, wheat rust, cotton aphid, rice sheath blight, rice blast, wheat bran, red spider, and aphid is achieved.

Description

technical field [0001] The present invention relates to an agricultural insecticide. Background technique [0002] Insecticide refers to an agent that kills pests, such as beetles, flies, grubs, noseworms, springtails, and nearly ten thousand other pests. The use of insecticides has gone through several stages: the first discovered are natural neutralizers and inorganic compounds, but they have a single effect, large dosage, and short duration; organic synthesis such as organochlorine, organophosphorus, and carbamate Insecticides are characterized by high efficiency and high residue or low residue, and many of them have high acute toxicity to mammals. [0003] Agricultural pesticides refer to insecticidal chemical preparations used in agriculture. Drugs mainly used to prevent and control agricultural pests and urban sanitation pests have a long history of use, a large amount of use, and many varieties. [0004] Afidopyropen (test code ME5343) is a new type of insecticide ...
