Problems solved by technology

[0005] (1) In the prior art, there is no oil-suspension agent for the prevention and treatment of the flea beetle, so it is necessary to develop an oil-suspension agent for the prevention and treatment of the flea beetle
[0006] (2) The above-mentioned patents use chemical organic substances as the active ingredients of the medicine. These organic substances will cause serious pollution and damage the environment, which does not conform to the principle of green production
[0007] (3) The dispersibility of the above-mentioned oil suspension concentrate is not good, thus affecting the insecticidal effect of the oil suspension concentrate product

Abstract

The invention discloses an oil suspending agent for preventing and treating phyllotreta vittata. The oil suspending agent for preventing and treating phyllotreta vittata comprises the following raw materials in parts by weight: 30-50 parts of folium digitalis, 22-36 parts of gelsmium elegans, 15-37 parts of Atropa belladonna, 10-18 parts of purslane, 5-15 parts of an emulsifier, 4-8 parts of a dispersing agent, 3-9 parts of a wetting agent, 2-6 parts of a thickening agent, 3-7 parts of an antifreezing agent, and 50-70 parts of a disperse medium. The oil suspending agent takes Chinese herbal medicines of folium digitalis, gelsmium elegans, Atropa belladonna and purslane as an effective component after being processed, the oil suspending agent can be obtained by adding the auxiliary materials of the emulsifier, the dispersing agent, the wetting agent and the thickening agent, through dilution, the oil suspending agent can be applied in the field of cruciferous vegetables, and especially aims at prevention and treatment of phyllotreta vittata. The oil suspending agent has the advantages of good dispersion performance, strong stickiness, rainwash resistance, and high active ingredient utilization rate, and the oil suspending agent has excellent prevention and treatment effects for phyllotreta vittata.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to an oil suspension for preventing and treating flea beetle and a preparation method thereof. Background technique [0002] The yellow striped flea beetle belongs to the order Coleoptera and Chloroptera. It mainly harms cabbage, cabbage and radish of the Brassicaceae, and can also harm solanaceous fruits, melons and legume vegetables. Oil suspension, referred to as oil suspension, refers to the formation of a highly dispersed and stable suspension system of one or more active ingredients of pesticides in the oil dispersion medium. [0003] The Chinese patent with the application number 2014100386191 discloses a pesticide oil suspension concentrate, which is composed of the following raw materials in weight percentage: 5-15% of cyflumetate; 5-15% of diafenthiuron; 7-9% of surfactant; Ethyl nonanoate 2-4%; polyvinylpyrrolidone 1-3%; stearyl alcohol 0.1-0.3%...
