Embodiment 1

[0018] Example 1: Indoor Toxicity Determination of Indoxacarb, Phyllostachys and their Mixtures on Tea Tree Leafhoppers with False Eyes

[0019] Test object: tea leafhopper (Empoasca flavescens) was collected from Nanjing County, Zhangzhou City, Fujian Province, cultivated on tea trees, and the same 3rd instar nymphs were picked for the test.

[0020] Test agent: 80% indoxacarb parent drug (Shandong Weifang Runfeng Chemical Co., Ltd.), 6% picroderm parent drug (Dongfeng Chemical Factory, Xinxiang City, Henan Province)

[0021] Test method: refer to (Zhuang Jiaxiang et al., 2009, Regional Differences of Insecticide Resistance of Leafhopper in Fujian Province) and Indoor Bioassay Test Guidelines for Pesticides Insecticides NY / T 1154.11-2008), using tip dipping method.

[0022] Sun Yunpei’s co-toxicity coefficient method (CTC) was used to evaluate the synergistic effect of drug mixture. When the co-toxicity coefficient (CTC) ≥ 120, the composition exhibited a synergistic effect; ...

Embodiment 2

[0030] Example 2: 2.5% indoxacarb·picterine suspension concentrate (indoxacarb:picterine=23:2)

[0031] Take by weighing indoxacarb 2.3%, phaetrifolia 0.2%, alkyl aryl polyoxypropylene polyoxyethylene ether 3.5% (dispersant), polynaphthalene sodium sulfonate 5.0% (wetting agent), B Diol 2.5% (antifreezing agent), xanthan gum 0.8%, 0.3% organic silicon defoamer, deionized water to make up to 100%.

[0032] The preparation method of Example 1-2 is as follows: mix each component uniformly according to the ratio of the formula, grind and high-speed shear to obtain an insecticidal composition containing indoxacarb·pictericin, and the dosage form is a suspension concentrate.

Embodiment 3

[0033] Example 3: 2.2% indoxacarb·picterine EC (indoxacarb:picterine=10:1)

[0034] Weigh 2.0% of indoxacarb, 0.2% of picroderm, 3% of sodium dodecylbenzenesulfonate (dispersant), 2.0% of octylphenol polyoxyethylene ether (emulsifier), dimethyl sulfoxide 5% (co-solvent), turpentine oil make up to 100%.

[0035] The preparation method of Example 3 is as follows: add indoxacarb and phatericin original drug, emulsifier and cosolvent, etc. in sequence according to the formula ratio into the mixing kettle, and stir evenly to obtain 2.2% indoxacarb·pictericin Cream.

Abstract

The invention relates to an insecticidal composition containing celastrus angulatus and indoxacarb. The insecticidal composition is prepared from the effective ingredients of indoxacarb and celastrus angulatus according to a weight ratio of (5 to 25):(1 to 2). The insecticidal composition has the advantages that the synergetic effect is achieved; the insecticidal composition is applicable to the prevention and control of empoasca pirisuga matumura; the insect resistance development can be delayed; the application dose of single dosage is reduced; the prevention and control effect is improved; meanwhile, the chemical pesticide residues are favorably reduced.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to an insecticidal composition containing picroderm and indoxacarb. Background technique [0002] Green leafhopper is a major pest that occurs commonly in tea areas and is highly harmful and should be controlled. Among them, green leafhopper with false eyes is the most serious. Indoxacarb is one of the medicaments for preventing and controlling the green leafhopper of tea, but its duration of effect is relatively short, and the cost of use is high. Highly effective insecticidal composition for green leafhoppers. [0003] Indoxacarb (indoxacarb) is a new type of oxadiazine insecticide. Its mechanism of action is to irreversibly block the sodium ion channels in the nerve cells of pests, destroy the nerve impulse transmission of pests, and cause target pests to lose control and stop. Feeds, paralyzes and eventually dies. It has contact and stomach poisoning functions, ...
