Compound pesticide of chlorantraniliprole and pyridaphenthion

Abstract

The invention discloses a compound pesticide of chlorantraniliprole and pyridaphenthion, which belongs to the technical field of pesticides. The compound pesticide of the chlorantraniliprole and the pyridaphenthion is characterized by containing 0.2 to 2.5 percent of the chlorantraniliprole and 9.0 to 29.8 percent of the pyridaphenthion. The compound pesticide of the chlorantraniliprole and the pyridaphenthion has the advantages of obvious synergic action, wide insecticidal spectrum, quick response, good lasting effect, low toxicity, small harms to the environment and human bodies, low production cost, and very good control effect on rice cnaphalocrocis medinalis and chilo suppressalis.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, in particular to a compound pesticide of chlorantraniliprole and pyridazinphos. Background technique

[0002] Chlorantraniliprole, whose chemical name is 3-bromo-N-{4-chloro-2-methyl-6-[(methylamino)carbonyl]phenyl}-1-(3-chloro-2 -pyridyl)-1H-pyrazole-5-amide, molecular formula: C 18 h 14 BrC 12 N 6 o 2 . Chlorantraniliprole is the first broad-spectrum insecticide with a new type of o-amidobenzamide chemical structure. The biggest feature of this insecticide is its unique chemical structure, novel mode of action, high-efficiency Biological performance and environmental ecological safety. Chlorantraniliprole can effectively control almost all important Lepidoptera pests and some other pests. It has special effects on rice stem borer, rice stem borer and rice leaf roller, and it has special effects on rice stem borer, rice bract moth and rice thrips. , rice bug beetle are effective, its ...

Examples

Embodiment 1

[0012] Example 1: Chlorantraniliprole uses N.N-dimethylformamide (D.M.F) as solvent, adds emulsifier to configure 10% emulsifiable concentrate; pyridazan also uses D.M.F as solvent, adds emulsifier to configure 30% emulsifiable concentrate According to the ratio of 1.0% chlorantraniliprole and 19.0% pyridazanil, a 20% chlorantraniliprole-pyridazinate mixture was prepared.

Embodiment 2

[0013] Embodiment 2: Chlorantraniliprole uses N.N-dimethylformamide (D.M.F) as solvent, adds emulsifier to configure 10% emulsifiable concentrate; pyridazan also uses D.M.F as solvent, adds emulsifier to configure 30% emulsifiable concentrate According to the ratio of 1.5% chlorantraniliprole and 18.5% pyridazanil, a 20% chlorantraniliprole-pyridazinate mixture was prepared.

[0014] Experiment 1: Determination of the efficacy of different mixture ratios of chlorantraniliprole and pyridazinon against Chilorrhizae.

[0015] The combined toxicity assay method was used, and the experimental ratio and results are shown in Table 1.

[0016] Table 1 The results of the determination of the efficacy of different ratios of chlorantraniliprole-pyridazinate mixture on 4-5 instar larvae of Chilo borer

[0017]

[0018] It can be seen from the preliminary screening of the content of the above-mentioned mixture that the drug effect is more appropriate when the total content is 20%. The...
