Description

Insecticidal composition containing cyflumetofen and dinotefuran and application thereof

Technical Field

The invention relates to the technical field of pesticide preparation, and particularly relates to an insecticidal composition containing cyflumetofen and dinotefuran and application thereof.

Background

Cyflumetofen with molecular formula C ₂₈ H ₁₇ BrF ₁₂ N ₂ O ₂ It is a new generation bisamide insecticide, mainly used for preventing and controlling lepidoptera and coleopteran pests of vegetables, perennial crops and grains, and sanitary pests of termites, flies, cockroaches and the like.

Dinotefuran, molecular formula C ₇ H ₁₄ N ₄ O ₃ It is the third generation of nicotine pesticide. The insecticidal composition has a wide insecticidal spectrum, can control various pests such as hemiptera, lepidoptera, hymenoptera and the like, has an obvious systemic osmosis effect, and shows insecticidal activity at a very low dose. The pesticide is very safe to mammals, birds and aquatic organisms, has no phytotoxicity to crops, and can be used for preventing and controlling pests of a plurality of crops such as rice, fruit trees, vegetables and the like. However, like many chemical insecticides, dinotefuran is resistant to long-term, continuous, single use. And because of long-term use of high-content original drug compound, the drug effect is not good, the cost is high, and the risk of drug injury is also caused.

In the actual agricultural production process, the application of chemical pesticide preparations is the most effective means for preventing and controlling plant diseases, pests and weeds, but the pests are easily subjected to drug resistance by the chemical pesticide preparations, and a series of environmental problems such as residue and pollution of the pesticide preparations are easily caused by long-time continuous high-dose application of single chemical pesticide preparations. The reasonable pesticide mixing has the advantages of expanding the insecticidal spectrum, improving the control effect, prolonging the pesticide application period, reducing the pesticide dosage, reducing the risk of pesticide damage, reducing environmental residues, delaying the generation and development of drug resistance and drug resistance of pests and the like.

Therefore, the problem to be solved by the technical personnel in the art is how to provide a pesticide composition with good insecticidal effect, small dosage and low chemical residue to solve the problems that in the prior art, a single chemical insecticide is easy to cause residue and pollution of pesticide preparations and has poor using effect.

The test site was Zhaoqing, Guangdong. The eggplant variety is Qingfeng purple eggplant, eggplant thrips occurs in a small amount, and the insect finger is low; the administration is started at the beginning of the onset of disease. Four cell replicates per agent treatment. Area of 20m per cell ² 15 g of the preparation is added into 5g of the preparation according to the insect conditionDiluting with 3000 times of water, uniformly spraying with industrial and agricultural-16 type backpack electric sprayer once, and investigating field control effect and insect population reduction rate 7 days after pesticide application. The test method and the pesticide effect statistical analysis method refer to pesticide field pesticide effect test criteria.

Results and analysis

As can be seen from table 1: the control effects of the single pesticides of the cyflumetofen and the dinotefuran on the eggplant thrips are respectively 81.0% and 73.3%, but the control effects of the insecticidal composition provided by the embodiment of the invention are remarkably improved, the minimum control effect is 87.3%, and the maximum control effect is 95.6%.
