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.
[0006] At present, the compound composition of pichamid and pyrimicarb has not been reported yet.

Embodiment 1

[0015] Formulation Example 1: 30% Pichamid·Zabicarb Water Emulsion

[0016] Pichridam (active ingredient) 8%

[0017] Pyramid (active ingredient) 22%

[0018] Trimethylbenzene (solvent) 15%

[0019] Sodium alkylbenzene sulfonate (emulsifier) ​​8%

[0020] Glycerol (stabilizing antifreeze) 5%

[0021] Water make up to 100%

[0022] 2. Preparation of microemulsion

[0023] 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.

[0024] Formulation Example 2: 40% Pichamid·Zabicarb Microemulsion

[0025] Pichridam (active ingredient) 10%

[0026] Pyramid (active ingredient) 30%

[0027] Acetone (solvent) 15%

[0028] DMF (solvent) 5%

[0029] Phenylphenol polyoxyethylene ether (emulsifier) ​​10%

Abstract

The invention discloses a synergistic insecticidal composition containing paichongding and triazamate. 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 triazamate, the weight ratio of the active ingredient A to the active ingredient B is 1:90 to 1:90 and preferably 1:55 to 1:55, and the total weight percentage of the two active ingredients in the composition is 5-70%. 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 plant hoppers or aphids generating hazards to various crops.

Description

technical field [0001] The invention relates to an agricultural insecticidal composition, in particular to a synergistic insecticide composition containing pichamid and pyrabicarb, 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, ...
