Embodiment 1

[0019] Embodiment one: 0.3% (mass %) azadirachtin general-purpose oil agent:

[0020] (1) adding 0.3% (mass %) azadirachtin;

[0021] (2) Add 79.3% (mass %) neem oil, so that the concentration of azadirachtin in the general oil agent is 0.3% (mass %);

[0022] (3) Add 0.1% (mass %) ethylene glycol as antifreeze;

[0023] (4) adding 20% ​​(mass %) nonylphenol polyoxyethylene ether as an emulsifier;

[0024] (5) Add 0.3% (mass %) acetic acid to adjust the pH of the solution so that the pH of the general-purpose oil is 6.0. First, heat nonylphenol polyoxyethylene ether and neem oil to 20-80 ° C, keep warm for 2 hours, and then cool To room temperature, add azadirachtin and ethylene glycol, and finally add acetic acid to make the pH of the solution 6.0. The prepared solution is sampled for analysis, testing and stability evaluation, and if it is qualified, it can be packaged and put into storage.

[0025] Field test: After diluting 0.3% neem oil agent 600 times, the diamondbac...

Embodiment 2

[0026] Embodiment two: 0.9% azadirachtin universal oil:

[0027] 1. Add 0.9% (mass %) azadirachtin;

[0028] 2. Add 78% (mass %) neem oil, so that the concentration of azadirachtin in the general oil agent is 0.9% (mass %);

[0029] 3. Add 1% (mass %) propylene glycol as antifreeze;

[0030] 4. Add 20% (mass%) alkylbenzenesulfonate sodium salt as emulsifier;

[0031] 5. Add 0.1% (mass %) acetic acid to adjust the pH of the solution so that the pH of the general-purpose oil is 6.5.

[0032] First, heat alkylbenzenesulfonic acid sodium salt and neem oil to 20-80°C, keep warm for 5 hours, then cool to room temperature, add azadirachtin and propylene glycol, and finally add acetic acid to keep the pH value of the solution at 6.5. The prepared solution is sampled for analysis, testing and stability evaluation, and if it is qualified, it can be packaged and put into storage.

[0033] Field test: after diluting 0.9% neem oil agent 1500 times, the diamondback moth larvae in the ca...

Embodiment 3

[0034] Embodiment three: 1.2% azadirachtin universal oil:

[0035] 1. Add 1.2% (mass %) azadirachtin;

[0036] 2. Add 70.3% (mass %) neem oil, so that the concentration of azadirachtin in the general oil agent is 1.2% (weight %);

[0037] 3. Add 3% (mass %) polyethylene glycol as antifreeze;

[0038] 4. Add 25% (mass %) triethanolamine salt as emulsifier;

[0039] 5. Add 0.5% (mass %) acetic acid to adjust the pH of the solution so that the pH of the general-purpose oil is 5.5.

[0040] First, heat triethanolamine salt and neem oil to 20-80°C, keep warm for 8 hours, then cool to room temperature, add azadirachtin and polyethylene glycol, and finally add acetic acid to keep the pH value of the solution at 5.5. The prepared solution is sampled for analysis, testing and stability evaluation, and if it is qualified, it can be packaged and put into storage.

[0041] Field test: After diluting 1.2% neem oil agent 2000 times, the diamondback moth larvae in the cabbage field are s...

Abstract

The invention relates to nimbin general oil solution insecticide. The insecticide is nimbin general oil solution which is prepared by taking nimbin and nim oil as active components and adding a proper quantity of an emulsifying agent, an antifreezing agent and an acidity regulator into the active components. Because the nim oil can protect the nimbin, the problem that the nimbin is easy to decompose is solved, the problems of pesticide residues and the environmental pollution caused by an organic solvent in components of a nim emulsifiable solution are also solved, and simultaneously the dosage form types of nimbin biological pesticides are also enriched.

Description

technical field [0001] The invention relates to an oil insecticide, in particular to a universal oil containing azadirachtin insecticidal activity. Background technique [0002] Neem (Azadirachta indica A.Juss.) is a tree of the family Meliaceae, native to the Indian subcontinent, and has various biological activities such as insecticidal, bactericidal and nematicidal. More than 80 kinds of insecticidal active substances, mainly azadirachtin, have been found in neem, which have biological activity on more than 400 kinds of agricultural, forestry, grain storage and health pests of more than 10 orders, and have little effect on natural enemies, without obvious Phytotoxicity and vertebrate toxicity, rapid degradation in the environment, abundant resources and renewable utilization, is a relatively perfect insecticide. In addition, azadirachtin also has a wide range of medicinal value, such as anti-malarial, antipyretic, deworming, and inhibiting the growth of fungi in animals ...
