Problems solved by technology

[0008] Under the condition of long-term single drug use, the resistance of the target to the drug gradually increases, and the effect of a single pesticide on pest control will gradually decrease, which greatly shortens the service life of a good drug
The inventors have found through research that the synergistic compounding of pesticides is an effective measure to expand the control spectrum and improve the control effect and prolong the use time of pesticides, and so far no patents on the insecticidal and fungicidal composition of dinotefuran and kresoxim-methyl have been found.

Embodiment 2

[0052] Weigh 5g of dinotefuran, 50g of kresoxim-methyl, 3g of phenylethylphenol polyoxyethylene ether phosphate, and Nongru 33 # 2g, 1g of alkylphenol polyoxyethylene ether, 13g of mineral spirits, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing water emulsion, and mix at high speed to prepare a water emulsion with a main active ingredient of 55% by weight.

Embodiment 3

[0054] Weigh 2g of dinotefuran, 30g of kresoxim-methyl, 6g of calcium dodecylbenzenesulfonate, 3g of phenylethylphenol polyoxyethylene ether phosphate, and 33 grams of agricultural milk # 2g, 1g of alkylphenol polyoxyethylene ether, 10g of isopropanol, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing microemulsions, and mix them to prepare a dinotefuran-kresoxim-methyl microemulsion with a weight percentage of 32% as the main active ingredient.

Abstract

The invention discloses a compound insecticidal and bactericidal composition containing dinotefuran and kresoxim-methyl, and an application thereof. The insecticidal and bactericidal composition employs dinotefuran and kresoxim-methyl as main effective components, wherein a weight ratio of dinotefuran to kresoxim-methyl is 0.1-85 : 0.5-85. The insecticidal and bactericidal composition can produce a relatively high synergistic interaction effect, is particularly suitable for preventing crop pests and diseases caused by various fungi. Besides, the usage amount of the mixture is significantly reduced than that of a single effective compound. Pesticide dosage is reduced in a real application, and pesticide cost is further reduced. The composition can prevent hemiptera pests, lepidoptera pests, coleoptera pests and fungous diseases which are generated on the crops, is particularly suitable for preventing rice planthopper, leafhopper, aphid, stinkbug, aleyrodid, powdery mildew, rust disease, epidemic disease, rice blast and the like, and has an effect obviously higher than that of a single dosage. Besides, the composition provided by the invention is especially suitable for treating seeds and protecting the seed resistance to diseases after the seeds sprout.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a compound insecticidal and fungicidal composition containing dinotefuran and kresoxim-methyl and its application. Background technique [0002] Dinotefuran is a third-generation neonicotinoid insecticide developed by Mitsui Chemicals. Its chemical structure is very different from that of the existing neonicotinoid insecticides. Its tetrahydrofuryl group replaces the previous chloropyridyl and chlorothiazolyl groups, and it does not contain halogen elements. At the same time, it is also different from nicotine in terms of performance. Therefore, it is currently called "furan nicotine". Dinotefuran chemical name: 1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine, the structural formula is as follows: [0003] [0004] The new-generation neonicotinoid insecticide dinotefuran mainly acts on the neurotransmitter system of insects, paralyzing them to death. The agent ...
