Problems solved by technology

[0005] Generally, with the frequent use of a single agent, pests tend to develop resistance to it, and chlorfenapyr is no exception.
Compounding pesticides with different mechanisms of action is a fast and simple way to delay the resistance of pests and diseases. At present, there are no reports and applications on the compounding of chlorfenapyr and picroderm for the control of tea leafhoppers.

Embodiment 1

[0018] Example 1: Indoor Toxicity Determination of Chlorfenapyr, 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 2nd instar nymphs were picked for the test.

[0020] Test agent: 97% chlorfenapyr original drug (Shandong Weifang Runfeng Chemical Co., Ltd.); 6% picroderm parent drug (produced by 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 sy...

Embodiment 2

[0030] Example 2: 3% chlorfenapyr·picterine suspension concentrate (chlorfenapyr:picterine=2.5:0.5)

[0031] Weigh 2.5% of chlorfenapyr, 0.5% of pectin, 2.0% of alkylaryl polyoxypropylene polyoxyethylene ether (dispersant), 3.5% of sodium polynaphthaldehyde sulfonate (wetting agent), and 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 chlorfenapyr·pichoridin, and the dosage form is a suspension concentrate.

Embodiment 3

[0033] Example 3: 4.2% chlorfenapyr·pichoridin water emulsion (chlorfenapyr:pichoraphanin=20:1)

[0034] Weigh 4.0% of chlorfenapyr, 0.2% of picrodine, 3.5% of biphenol polyoxyethylene ether, 10% of xylene, 5.0% of calcium dodecylbenzenesulfonate, 0.8% of organic silicon, and make up to 100%.

Abstract

The invention relates to an insecticidal composition containing chlorfenapyr and celastrus angulatus. The insecticidal composition is prepared from the following effective ingredients of chlorfenapyr and celastrus angulatus according to a weight ratio of (5 to 20):1. The insecticidal composition has the advantages that a synergetic effect is achieved; the pesticide application quantity can be effectively reduced; the pesticide cost and the pesticide residues are reduced; meanwhile, the resistance development of empoasca pirisuga matumura is favorably delayed.

Description

technical field [0001] The invention relates to the field of pesticide compounding, in particular to an insecticidal composition containing chlorfenapyr and picroderm. Background technique [0002] The green leafhopper is a common and harmful pest in tea areas, among which the green leafhopper with false eyes is the most serious. Bifenthrin is a common agent used to control tea leafhoppers in tea areas. However, due to long-term single and frequent use, the resistance of tea leafhoppers to it increases, resulting in a decline in the control effect and efficacy. [0003] Chlorfenapyr (chlorfenapyr) is a new type of pyrrole compound, which acts on the mitochondria of cells in insects, acts through the multifunctional oxidase in insects, and mainly inhibits the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). Adenosine triphosphate stores the energy necessary for cells to maintain their vital functions. The drug has stomach poisoning, contact killing...
