Problems solved by technology

However, the long-term use of a single type of pesticide is likely to promote the resistance of pests to a certain extent. For this reason, farmers often use more pesticides to achieve the purpose of eliminating pests.
However, there are problems in using this method, which will cause greater pollution to the environment and pesticide residues, and at the same time indirectly increase the cost of pesticides for farmers.
[0007] The compound composition of Pichamid and Daofengsan has not been reported yet

Embodiment Construction

[0013] Below in conjunction with example the present invention will be further described. However, the present invention is by no means limited to these examples. The percentages or proportioning in all formulas are percentages by weight or ratios by weight. Processes and equipment for processing various formulations of the compositions of the present invention are known to the public.

[0014] 1. Preparation of water emulsion

[0015] Dissolve the active ingredient in a solvent, add an emulsifier and stir until it becomes transparent as the oil phase, and mix the stable antifreeze agent and water uniformly as the water phase. Under the high-shear condition of 3000-6000 rpm, slowly add the oil phase to the water phase and stir for 20-50 minutes to form a water emulsion with good dispersibility.

[0016] Preparation Example 1: 40% Pichamid·Daofeng San Water Emulsion

[0017] Picloprid (active ingredient) 8%

[0018] Daofengsan (active ingredient) 32%

[0019] Trimethylben...

Abstract

The invention provides a synergistic insecticidal composition containing chloropyridine and phenthoate. The composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is chloropyridine; the active ingredient B is phenthoate; the weight ratio of the active ingredient A to the active ingredient B is (1 to 95)-(1 to 95), preferably (1 to 65)-(1 to 65); the total weight percentage of the two active ingredients in the composition is 5-80%. The dosage forms of the composition are one or more of suspending agents, microemulsion and emulsion in water. The composition can be used for controlling plant hoppers or aphids harming various crops.

Description

technical field [0001] The invention relates to an agricultural insecticide composition, in particular to a synergistic insecticide composition containing pichridam and daofengsan, which can be used to prevent and control agricultural pests, especially planthoppers 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 varieties to replace imidacloprid to control planthoppers 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, ...
