[0030] Example 2: Powdered composition and its preparation and use.

[0031] A powdery composition, its powder particle size is 1000nm, it comprises 15g pyrethrum, 5g capsicum, 5g garlic extract, 5g cinnamon, 15g camphor tree seed, 15g banana stem, 8g tea seed dregs, 30g diatomaceous earth, 8g aloe extract and 15g of tea fruit, which was prepared by mixing pyrethrum, capsicum, garlic extract, cinnamon, camphor tree seed, banana stalk, tea seed meal, diatomaceous earth, aloe vera extract and tea fruit and crushing until powder particle size at 1000 nm, a powdery composition was obtained.

[0032] The above-mentioned powdery composition is applied on the paddy rice that suffers from rice caterpillar (scientific name rice borer, Naranga aenescensMoore) pest (such as figure 2 A), the specific process is as follows:

[0033] 1) Mix 10g of the powdery composition with 6000g of water and stir evenly to obtain a dilution of the powdery composition;

[0034] 2) According to the dos...

Embodiment 3

[0036] Example 3: Powdered composition and its preparation and use.

[0037] A powdery composition, its powder particle size is 800nm, it comprises 12g pyrethrum, 3g capsicum, 3g garlic extract, 3g cinnamon, 12g camphor tree seed, 12g banana stem, 6g tea seed dregs, 25g diatomaceous earth, 6g aloe extract and 12 g of Sapindus, which was prepared by mixing and pulverizing pyrethrum, chili, garlic extract, cinnamon, camphor seeds, banana stems, tea seed meal, diatomaceous earth, aloe extract, and Sapind until The particle size of the powder was 800 nm, resulting in a powdery composition.

[0038] Above-mentioned powdery composition is applied on the dragon fruit tree that suffers from caterpillar infestation (as image 3 A), the specific process is as follows:

[0039] 1) Mix 10g of the powdery composition with 5000g of water and stir evenly to obtain a dilution of the powdery composition;

[0040]2) According to the dose of 50kg / mu, spray the powdered composition dilution on...

Abstract

The invention discloses a powder-like composition and a preparation method and application thereof .Specifically, the powder size of the powder-like composition ranges from 500 nm to 1,000 nm, and the powder-like composition is prepared from, by weight, 10-15 parts of pyrethrum, 2-5 parts of peppers, 2-5 parts of garlic extract, 2-5 parts of cortex cinnamomi, 10-15 parts of camphor tree seeds, 10-15 parts of banana stalk, 5-8 parts of a tea seed cake, 20-30 parts of kieselguhr, 5-8 parts of aloe extract and 10-15 parts of fruits of soapberry trees or tea trees .The powder-like composition can effectively kill injurious insects with the size larger than aphids by stimulating and expanding the respiratory tracts of the injurious insects; the powder-like composition can not pollute the environment and is beneficial to ecological environment protection; the powder-like composition is safe and free of toxin, reaches the food level, can be used for organic planting of crops and can ensure the product quality of planted crops .

Description

technical field [0001] The invention belongs to the technical field of biopesticides, and relates to a powder composition, a preparation method thereof, and an application thereof in preparing biopesticides for preventing and controlling insect pests. Background technique [0002] China is a large agricultural country, and agriculture occupies an important basic position in our national economy. As the most populous country in the world, my country produces about 25% of the world's food with less than 10% of the world's arable land, and feeds more than 22% of the world's population. However, the crop diseases and insect pests in agricultural production are one of the main disasters in our country. They have the characteristics of various types, great influence and frequent outbreaks, and often cause great losses to our national economy (especially agricultural production). [0003] Common crop diseases and insect pests in my country include powdery mildew (mainly harming wh...
