Embodiment 1

[0044] Embodiment 1 insecticide and its preparation and application

[0045] Mix 70kg of glucose, 20kg of inorganic salt and 7kg of three insect powder, wherein the composition of inorganic salt is: 18kg of ammonium sulfate, 1.54kg of potassium dihydrogen phosphate, 100g of magnesium sulfate, 160g of ferrous sulfate and 200g of zinc sulfate. In addition, 10kg of Bacillus subtilis raw powder with a viable count of not less than 100 billion cfu / g was added to obtain a mixture of microorganisms and nutrients with a viable count of not less than 10 billion cfu / g. At the same time, 10 L of synergistic agents were prepared, including 2.5 L of sapinberry solution, 7.5 L of mixed solution of 3% polyglutamic acid and 1% betaine.

[0046] The specific production method of the insecticide is as follows: take 1kg of the mixed product and put it into 100L water to multiply and ferment in a well-ventilated place, ferment and cultivate at 30°C for 48 hours, use an air compressor to supply ai...

[0047] Embodiment 2 insecticide and its preparation and application

[0048]Mix 60kg of brown sugar, 28.35kg of inorganic salt and 5kg of three worm powder with 1kg of collagen powder, wherein the composition of inorganic salt is: 25kg of ammonium sulfate, 2.5kg of potassium dihydrogen phosphate, 300g of magnesium sulfate, 250g of ferrous sulfate and 300g of zinc sulfate. In addition, 6.65 viable bacteria counts are not less than 100 billion cfu / g Bacillus subtilis powder to obtain a mixture of microorganisms and nutrients with a viable count of not less than 10 billion / cfu. At the same time, 10 L of synergists were prepared, including 2 L of Sapinberry liquid, 8 L of mixed solution of 3% polyglutamic acid and 1% betaine.

[0049] The specific production method of the insecticide is as follows: take 1kg of the mixed product and put it into 100L water for propagation and fermentation, and ferment and cultivate for 48 hours at 25°C. During the fermentation process, use an air co...

Embodiment 3

[0050] Embodiment 3 insecticide and its preparation and application

[0051] Mix 75kg of sucrose, 15kg of inorganic salt, 2kg of collagen and 2kg of crab shell powder. The inorganic salt is composed of 13kg of ammonium sulfate, 1.25kg of potassium dihydrogen phosphate, 100g of magnesium sulfate, 250g of ferrous sulfate and 200g of zinc sulfate. In addition, 6 kg of viable bacteria count is 100 billion cfu / g Bacillus subtilis bacteria powder to obtain a mixture of microorganisms and nutrients with a viable count of not less than 10 billion / cfu. At the same time, 10 L of synergists were prepared, including 3 L of Sapinberry liquid, 7 L of mixed solution of 3% polyglutamic acid and 1% betaine.

[0052] The specific production method of the insecticide is as follows: take 1kg of the mixed product and put it into 100L water for propagation and fermentation, and ferment and cultivate it at 25°C-38°C for 48 hours. During the fermentation process, use an air compressor to supply air o...

Abstract

The invention discloses a spodoptera frugiperda insecticide as well as a preparation method and application thereof. The insecticide comprises at least one microbial agent and at least one synergist,wherein the microbial agent consists of bacillus subtilis and a nutritional agent required by the bacillus subtilis; the synergist comprises at least one plant saponin extract. The preparation methodof the insecticide comprises the steps: mixing and fermenting the microbial agent, the nutritional agent and water, and mixing the obtained fermentation liquor with the synergist according to a certain proportion. In practical application, the insecticide can be sprayed to crops, including foliage spraying, ground spraying, flood irrigation and the like. The method has a good prevention and control effect on field pests (especially spodoptera frugiperda), is free of pesticide addition, does not enable crops to generate drug resistance, and has great significance in preventing and controlling spodoptera frugiperda and protecting grain production safety in China.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to an insecticide against Spodoptera frugiperda and its preparation method and application. Background technique [0002] Spodoptera frugiperda is a species of moth in the family Noctuidae. Native to the tropical regions of America, it has strong migratory ability and is also a pest that seriously threatens agricultural production. The insect has significant biological advantages such as wide suitable habitat area, wide host range, strong proliferation potential, fast diffusion speed, and serious sudden damage, so its prevention and control is very difficult. At present, the worm has been distributed to more than 100 countries around the world. Spodoptera frugiperda can be divided into "maize type" and "rice type" according to host preference, and the maize type mainly prefers corn, sorghum and cotton. Rice type prefers rice type and so on. The ones distributed in our...
