Embodiment 1

[0016] Formulation example 1: 15% chlorfenapyr aqueous emulsion

[0017] Piclopyr (active ingredient) 7%

[0018] Chlorfenapyr (active ingredient) 8%

[0019] Trimethylbenzene (solvent) 15%

[0020] Sodium alkylbenzene sulfonate (emulsifier) ​​8%

[0021] Glycerol (stabilizing antifreeze) 5%

[0022] Water make up to 100%

[0023] 2. Preparation of microemulsion

[0024] Dissolve the active ingredient with a solvent and a co-solvent, add an emulsifier and stir until it becomes transparent as the oil phase, and mix the stable antifreeze with water uniformly as the water phase. Slowly add the oil phase into the water phase and stir for 30-60 minutes to form a microemulsion with good dispersibility.

Embodiment 2

[0025] Formulation Example 2: 20% Pichamid·chlorfenapyr microemulsion

[0026] Pichridam (active ingredient) 8%

[0027] Chlorfenapyr (active ingredient) 12%

[0028] Acetone (solvent) 15%

[0029] DMF (solvent) 5%

[0030] Phenylphenol polyoxyethylene ether (emulsifier) ​​10%

[0031] Nongru 500# (emulsifier) ​​5%

[0032] Ethylene glycol (stabilizing antifreeze) 2%

[0033] Water top up to 100%

[0034] 3. Preparation of suspending agent

[0035] The active ingredient, dispersant, wetting agent, thickener and water are uniformly mixed sequentially according to the proportion of the formula, and the suspending agent is obtained after being ground by a sand mill.

Embodiment 3

[0036] Formulation example 3: 30% chlorfenapyr suspension concentrate

[0037] Pichridam (active ingredient) 10%

[0038] Chlorfenapyr (active ingredient) 20%

[0039] Sodium alkylbenzene sulfonate (dispersant) 6%

[0040] Alkylphenol polyoxyethylene ether (wetting agent) 4%

[0041] Xanthan gum (thickener) 0.3%

[0042] Water top up to 100%

[0043] Examples of bioassay and drug efficacy test:

[0044] 1. Indoor toxicity determination of Nilaparvata lugens compounded with chlorfenapyr and chlorfenapyr

[0045] The original drug of the test drug pichamidin was produced by Jiangsu Kesheng Group Co., Ltd., and the original drug of chlorfenapyr was the original drug of Xinyi Yonglong Chemical Co., Ltd. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T 1154.11-2008". After preparing the mother liquor with acetone, an organic solvent for the original drug, use 0.1% Tuwen-80 aqueous solution to prepare 5 series of mass concentrations...

Abstract

The invention discloses a synergistic insecticidal composition containing paichongding and chlorfenapyr. The synergistic insecticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A refers to paichongding, the active ingredient B refers to chlorfenapyr, the weight ratio of the active ingredient A to the active ingredient B is 1:70 to 1:70 and preferably 1:50 to 1:50, and the total weight percentage of the two active ingredients in the composition is 5-50%. The composition can be prepared into one or more dosage forms selected from a suspending agent, a microemulsion and an emulsion in water. The composition disclosed by the invention can be used for preventing and controlling thrips or aphids generating hazards to various crops.

Description

technical field [0001] The invention relates to an agricultural insecticide composition, in particular to a synergistic insecticide composition containing chlorpyrid and chlorfenapyr, which can be used to prevent and control agricultural pests, especially thrips and aphids. Background technique [0002] Pichamid is a new neonicotinoid insecticide with high efficiency, broad spectrum and low toxicity developed by Kesheng Group. It is mainly used to control Homopteran pests. At present, imidacloprid is one of the most widely used insecticides in the world, but due to its large and frequent use, it has caused significant resistance worldwide, and the activity of picloprid against resistant sap-sucking pests is significantly higher than that of imidacloprid. Therefore, Picloprid is one of the ideal species to replace imidacloprid to control thrips and aphids. The chemical name of piperacridin is: 1-((6-chloropyridin-3-yl)methyl)-5-propoxy-7-methyl-8-nitro-1,2,3,5,6, 7-hexahydr...
