Problems solved by technology

[0010] When these insecticides are used alone, the insecticidal spectrum is relatively narrow, and the effect is single, and it is easy to overuse, and repeated use of a single agent in a production season can easily lead to insecticide resistance.
[0011] In addition, most of these agents are processed into emulsifiable concentrates, soluble liquids, and wettable powders. The emulsifiable concentrates and soluble liquids require a large amount of solvents, and wettable powders are prone to dust, which will cause serious pollution to the environment.
[0012] In the current use technology, pyraclofen is used alone or in combination with other insecticides and acaricides. It has not been combined with acetamiprid, imidacloprid, thiamethoxam, thiacloprid, clothianidin, dinotefuran Substantial public reports on the combined use of other pesticides

Embodiment 1

[0031] Example 1: After mixing different varieties of pesticides, there are usually three types of effects: additive effect, synergistic effect and antagonistic effect. However, the specific role cannot be determined without a large number of experiments. In order to prevent and control pests that produce resistance in agriculture, the applicant of the present invention firstly passed the indoor biological activity assay test and found that the mixed use of pyraclofen and neonicotinoid insecticides has obvious synergistic effect on pests. This composition was subjected to a quantitative analysis of synergistic effect.

[0032] The test method refers to the "Agricultural Industry Standard of the People's Republic of China NY / T1154.7-2006" for indoor bioassays, and the third instar larvae of Spodoptera litura are selected as the target pests. According to the different ratios of pyraclofen and neonicotinoid insecticides in Tables 1, 2, and 3, different concentrations were prepa...

Embodiment 2

[0042] Example 2: Dissolve 1 kg of pyraclofen and 9 kg of thiacloprid in 15 kg of cyclohexanone, 10 kg of methyl esterified vegetable oil, 4.5 kg of alkylphenol formaldehyde resin polyoxyethylene ether, 4.5 kg of triphenylethyl Add 100 kg of water to the phenol polyoxyethylene polyoxypropylene ether phosphate and 1.5 kg of calcium dodecylbenzenesulfonate emulsifier, and stir evenly to obtain 10% pyraclofen-thiacloprid microemulsion.

Embodiment 3

[0043] Example 3: Dissolve 5 kg of pyraclofen and 15 kg of thiacloprid in 20 kg of octylpyrrolidone, then add 5 kg of styrylphenol polyoxyethylene polyoxypropylene ether phosphate, 2 kg of fatty alcohol polyoxyethylene ether, make up 100 kg with water, stir at high speed for 30 minutes, then add 0.3 kg of polyvinyl alcohol as a thickener, and stir evenly to obtain 20% thiacloprid thiacloprid emulsion in water.

Abstract

The invention relates to a composite with fenpyroximate which is characterized by being mixed and prepared by fenpyroximate and nicotine compound used as active components, additive and solvent or filler, wherein nicotine compound is selected from any one of scetamiprid, imidacloprid, thiamethoxam, thiacloprid, clothianidin and dinotefuran and the components of the composite are as follows by weight percent: 1-25% of fenpyroximate, 1-50% of nicotine compound, 2-15% of additive and the balance solvent or filler. The composite can be processed into dosage forms such as emulsion in water, microemulsion, water dispersible granules, suspending concentrate and the like to use. When using the composite of the invention to control injurious insects, the readily availability and the persistence canbe increased and the synergy is obvious so as to facilitate to reduce the use of pesticides, reduce the drug cost and delaying the generation of insect resistance to pesticides.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition with pyraclofen and nicotinic pesticides as active ingredients. Background technique [0002] In recent years, the occurrence and development of crop diseases and insect pests has been extraordinary. In order to ensure a good harvest of crops, more and more pesticides are used, and the amount of pesticides is increasing, and the safety of agricultural products is becoming more and more serious. It is an urgent task for pesticide research institutions and production enterprises to develop and use high-efficiency, low-toxicity and low-residue pesticide products. [0003] Fenpyroximate is a new type of pyrazoline ester acaricide, the English common name is fenpyroximate, the chemical name is: E-(1,3-dimethyl-5-phenoxypyrazole-4-methyleneaminooxy) p Tert-butyl toluate, molecular formula: C 24 h 27 N 3 0 4 . The mode of action of fenpyroxen is mainly contact act...
