Technical Field

The invention relates to an insecticidal composition, in particular to an insecticidal composition containing flubendiamide and trifluorophenylpyrimidine, belonging to the technical field of pesticide compounding.

Background

Crop diseases and insect pests are one of the main agricultural disasters in China, and the crop diseases and insect pests have the characteristics of multiple varieties, great influence and frequent outbreak of disasters, and the occurrence range and the severity of the crop diseases and insect pests cause great loss to national economy, particularly agricultural production in China. The following types of plant diseases and insect pests are common in crops in China: the pesticide composition is characterized by comprising the following components of rice leaf roller, chilo suppressalis, asparagus caterpillar, diamond back moth, rice planthopper, powdery mildew, corn borer, cotton bollworm, wheat rust disease, cotton aphid, rice sheath blight, rice blast, wheat aphid, wheat red spider, locust, wheat scab and the like, and has become a major pest and disease damage which seriously affects the agricultural production in China.

The chemical structure of the flubendiamide is as follows:

chemical name: 3-bromo-1- (3-chloropyridin-2-yl) -N- [4, 6-dichloro-3-fluoro-2- (methylaminocarboxamide) phenyl]-1H-pyrazole-5-carboxamide; experimental formula (II): c₁₇H₁₀BrC_l3FN₅O₂(ii) a Relative molecular mass (in 2009 international relative atomic mass): 521.56, respectively; and (3) biological activity: killing insects; melting Point (. degree. C.): 238-240.

The flubendiamide is a new compound independently innovated and developed by our company, belongs to benzamide insecticides, and can efficiently activate insect ryanodine (muscle) receptors to excessively release calcium ions in intracellular calcium stores, so that insects die by paralysis. High activity to lepidoptera pest larva, broad spectrum and high durability. The active ingredients show extremely obvious selectivity difference to mammals and pests, namely the ryanodine receptor, and greatly improve the safety to the mammals and other vertebrates.

Trifluoropyrimidine is a novel mesoionic or zwitterionic pesticide developed by DuPont, and is also a novel pyrimidinone compound. The composition has high efficiency, lasting effect, low dosage and environmental protection, and is mainly used for preventing and treating rice planthoppers, leafhoppers and the like. It has different action mechanism with neonicotinoid insecticide and has no adverse effect on pollinating insects.

The applicant finds that the compound of the florfenicol bisamide and the trifluoro-benzene pyrimidine with different action mechanisms has the following advantages and beneficial effects by compounding the florfenicol bisamide and the trifluoro-benzene pyrimidine according to experiments: 1. by using a compound scheme, the insecticidal composition has obvious synergy on hemiptera, thysanoptera, lepidoptera and homoptera pests such as tea lesser leafhoppers, aphids, thrips, diamond back moths, plant hoppers and the like, and obviously improves the control effect; 2. the dosage and the frequency of medication are reduced, and the prevention and treatment cost is reduced; 3. overcomes the defect of easy generation of resistance after long-term single use, and prolongs the service life of the medicament.
