Embodiment 1

[0021] (1) First wash Polygonum rubrascens and Pteridocarpus with clean water, dry and crush them, and pass through a 100-mesh sieve;

[0022] (2) Mix 5 kg of Polygonum rubrum powder with 5 kg of Polygonum rubrum powder after sieving, add 50 L of ethanol, and extract under reflux at 40°C for 4 hours to obtain the extractant of the mixture of Polygonum rubrum and Rhizoma rubrum;

[0023] (3) concentrating the extractant of the mixture of Polygonum rubrum and Ligium fern at 60°C under reduced pressure to remove the ethanol solvent to obtain the extract extract of the mixture of Polygonum rubrum and Ligium fern;

[0024] (4) Polygonum rubrum-Pteris emulsifiable cream Pesticide configuration: Raw material ratio: 1 kg of extract extract from the mixture of Polygonum rubrum and Fern fern, 0.1 kg of ethanol, 0.05 kg of Tween-800.05 kg, 8.85 kg of hard water. Dissolve the extract extract with ethanol first, then add the rest of the ingredients and mix.

Embodiment 2

[0026] (1) First wash Polygonum rubrascens and Pteridocarpus with clean water, dry and crush them, and pass through a 100-mesh sieve;

[0027] (2) After mixing 9 kg of Polygonum rubrum powder and 1 kg of Rhizoma Polygonum powder through the sieve, add 300L of ethanol, and extract under reflux at 98°C for 12 hours to obtain the extractant of the mixture of Polygonum rubrum and Rhizoma rubrum;

[0028] (3) Concentrating the extractant of the mixture of Polygonum rubrum and Ligium fern at 60° C. under reduced pressure to remove the ethanol solvent to obtain the extract of the mixture of Polygonum rubrum and Ligium fern.

[0029] (4) Pesticide configuration of Polygonum Polygonum-Pteris chinensis EC: Raw material ratio: 3 kg of extract extract from the mixture of Polygonum Polygonum and Pteridophyllum, 0.3 kg of ethanol, 0.2 kg of Tween-800.2 kg, and 6.5 kg of hard water. Dissolve the extract extract with ethanol first, then add the rest of the ingredients and mix.

Embodiment 3

[0031] (1) First wash Polygonum rubrascens and Pteridocarpus with clean water, dry and crush them, and pass through a 100-mesh sieve;

[0032] (2) After mixing 8 kg of Polygonum rubrum powder and 2 kg of Polygonum rubrum powder through the sieve, add 200 L of ethanol, and extract under reflux at 80°C for 10 hours to obtain the extractant of the mixture of Polygonum rubrum and Rhizoma rubra;

[0033] (3) Concentrating the extractant of the mixture of Polygonum rubrum and Ligium fern at 60° C. under reduced pressure to remove the ethanol solvent to obtain the extract of the mixture of Polygonum rubrum and Ligium fern.

[0034] (4) Pesticide configuration of Polygonum Polygonum-Pteris chinensis EC: Raw material ratio: 1.8 kg of extract extract from the mixture of Polygonum sylvestris and P.

Abstract

The invention provides a botanical pesticide for preventing and treating potato ring rot and a preparation method of the botanical pesticide. The botanical pesticide takes an extract of a mixture of smartweed and athyrium niponicum as a main raw material; a solvent ethanol, an emulsifying agent Tween-80 and hard water are used; and then a mixture is packaged to obtain a smartweed-athyrium niponicum missible oil pesticide product. Potato seeds or potato blocks are immersed by the smartweed-athyrium niponicum missible oil pesticide to achieve the better prevention and treatment effect. The smartweed-athyrium niponicum missible oil pesticide disclosed by the invention not only has good effect in preventing and treating the potato ring rot, but also is harmless to potatoes and does not pollute soil, an underground water source and agricultural products; and the botanical pesticide is safe to human beings, has the effect of green manures and can improve soil physical and chemical properties, so that the botanical pesticide is an ideal botanical pesticide.

Description

technical field [0001] The invention relates to a botanical pesticide, in particular to a natural botanical pesticide for preventing and treating potato ring rot, which uses a mixture of Polygonum rubra powder and Pteridocarpus powder as main raw materials and a preparation method thereof. Background technique [0002] Potato ring rot, also known as ring rot, commonly known as ring rot and yellow eye circle, is a worldwide vascular disease caused by bacteria. In my country, the disease was first discovered in Heilongjiang in the 1950s. Later, due to the transportation of seed potatoes, it was successively spread to Jilin, Liaoning, Inner Mongolia, Gansu, Qinghai, Ningxia, Hebei, Beijing, Shanxi, Shaanxi, Shandong, Zhejiang, Shanghai, Guangxi and other places. At present, it has spread all over the country's potato-producing areas. After potatoes are damaged by ring rot, the plants often cause severe wilting or even death, which has a great impact on yield, and the land wit...
