Problems solved by technology

[0007] 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 azoxystrobin have been found.

Embodiment 2

[0050] Weigh 5g dinotefuran, 50g azoxystrobin, 3g phenethylphenol polyoxyethylene ether phosphate, agricultural milk 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 emulsion in water and mix at high speed to prepare a water emulsion with a main active ingredient of 55% by weight of dinotefuran-azoxystrobin.

Embodiment 3

[0052] Weigh 2g of dinotefuran, 30g of azoxystrobin, 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-azoxystrobin microemulsion with a weight percentage of 32% as the main active ingredient.

Abstract

The invention discloses an insecticide/bactericide composition containing dinotefuran and azoxystrobin and application thereof. The insecticide/bactericide composition takes dinotefuran and azoxystrobin as main active ingredients, wherein the weight ratio of dinotefuran to azoxystrobin is (0.1-85):(0.5-75). The insecticide/bactericide composition has the beneficial effects that the insecticide/bactericide composition can have higher synergy and is especially suitable for controlling diseases caused by crop pests and various fungi; the dosage of the mixture is greatly reduced compared with that of the independent active compound; the drug dosage is reduced in practical application and then the drug cost is reduced; the insecticide/bactericide composition can control the diseases caused by hemiptera, lepidoptera and coleoptera pests on the crops and fungi; and besides, the composition is also especially suitable for treating seeds and protecting the seeds from the diseases after germination.

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 azoxystrobin 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. [0003] The new-generation neonicotinoid insecticide dinotefuran mainly acts on the neurotransmitter system of insects, paralyzing them to death. The agent has a wide insecticidal spectrum, excellent systemic ...
