Embodiment 1

[0019] A biological insecticide suitable for seasonal vegetables, comprising: weighing the following components by weight: 1 part of Bacillus thuringiensis emulsion, 2 parts of azadirachtin, 1 part of caterpillar fungus, 4 parts of insect repellent, and 3 parts of glucose , 10 parts of high-concentration active liquid, 30 parts of distilled water, and prepare according to the following method:

[0020] S1: Prepare a high-concentration active liquid, and weigh the following components by weight: 1 part of sodium chloride, 1 part of potassium chloride, 0.5 part of vitamin E, 1 part of peptone, and 6 parts of distilled water. Fully dissolve after stirring, and then put it in a high-pressure steam pot for sterilization. The pressure in the high-pressure steam pot is 100kpa, and the sterilization temperature is 120°C for 20 minutes. When the temperature reaches 55°C, add glucose and keep stirring. After the glucose is fully dissolved, continue to cool and set aside;

[0021] S2: C...

Embodiment 2

[0026] A biological insecticide suitable for seasonal vegetables, comprising: weighing the following components by weight: 2 parts of Bacillus thuringiensis emulsion, 3 parts of azadirachtin, 1.5 parts of caterpillar fungus, 6 parts of insect repellent, and 4 parts of glucose , 15 parts of high-concentration active liquid, 40 parts of distilled water, and prepare according to the following method:

[0027] S1: Prepare a high-concentration active liquid, and weigh the following components by weight: 2 parts of sodium chloride, 2 parts of potassium chloride, 0.8 parts of vitamin E, 1.5 parts of peptone, and 7 parts of distilled water. Fully dissolve after stirring, and then put it in a high-pressure steam pot for sterilization. The pressure inside the high-pressure steam pot is 115kpa, and the sterilization temperature is 125°C for 20 minutes. When the temperature reaches 60°C, add glucose and keep stirring. After the glucose is fully dissolved, continue to cool and set aside; ...

[0033] A biological insecticide suitable for seasonal vegetables, comprising: weighing the following components by weight: 3 parts of Bacillus thuringiensis emulsion, 4 parts of azadirachtin, 2 parts of caterpillar bacteria, 7 parts of insect repellent, and 5 parts of glucose , 20 parts of high-concentration active liquid, 50 parts of distilled water, and prepare according to the following method:

[0034] S1: Prepare a high-concentration active liquid, and weigh the following components by weight: 3 parts of sodium chloride, 3 parts of potassium chloride, 1 part of vitamin E, 2 parts of peptone, and 8 parts of distilled water. Fully dissolve after stirring, and then put it in a high-pressure steam pot for sterilization. The pressure in the high-pressure steam pot is 130kpa, and the sterilization temperature is 130°C for 20 minutes. When the temperature reaches 65°C, add glucose and keep stirring. After the glucose is fully dissolved, continue to cool and set aside;

Abstract

The invention discloses a biological pesticide applicable to seasonal vegetables. The biological pesticide comprises the following components in parts by weight: 1-3 parts of a bacillus thuringiensisemulsion, 2-4 parts of azadirachtin, 1-2 parts of entobacterin, 4-7 parts of a pest repellent, 3-5 parts of glucose, 10-20 parts of high-concentration active liquid and 30-50 parts of distilled water.Through collocation of the high-concentration active liquid, increase in the residence time of the entobacterin when being sprayed onto the vegetables is facilitated, prolonging of the duration of the pesticide is facilitated, and reduction in the pesticide spraying frequency is facilitated; through addition of the pest repellent into the pesticide, the purpose of repelling pests can be achieved,so that the pest damage probability of the vegetables can be reduced; the bacillus thuringiensis emulsion and the azadirachtin can kill the pests which cannot be repelled, so that the pest damage range is effectively reduced; the pesticide can protect and control the vegetables at the same time, so that loss of vegetable farmers is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a biological pesticide suitable for seasonal vegetables. Background technique [0002] Biopesticides are mainly divided into three categories: Bacillus thuringiensis, insect virus, and plant extracts. They have the characteristics of convenient material acquisition, low cost, long control period, high efficiency, economy, safety, no pollution, and high compatibility with the environment. It is the best pesticide choice for the current production of pollution-free green vegetables. There are many kinds of microbial pesticides, and more than 2,000 kinds have been found. According to the classification of microorganisms, they can be divided into bacteria, fungi, viruses, protozoa and nematodes. At present, domestic research, development, application and commercialization of products mainly include bacterial insecticides, fungal insecticides, virus insecticides and an...
