Embodiment 1

[0014] The fresh sisal leaves are chopped and extracted by alcohol extraction to obtain the alcohol extract of sisal leaves; the dried Artemisia annua is crushed and extracted by water extraction to obtain the water extract of Artemisia annua.

[0015] Take 7 parts of matrine, 12 parts of sisal leaf ethanol extract, 3 parts of Bupleurine, 3 parts of arecoline, and 15 parts of water extract of Artemisia annua, and mix them evenly. (It should be understood that this botanical fungicide can be further processed into various water-soluble pesticide formulations.)

Embodiment 2

[0017] The fresh sisal leaves are chopped and extracted by alcohol extraction to obtain the alcohol extract of sisal leaves; the dried Artemisia annua is crushed and extracted by water extraction to obtain the water extract of Artemisia annua.

[0018] Take 8 parts of matrine, 13 parts of sisal leaf ethanol extract, 2 parts of Bupleurine, 2 parts of arecoline, and 16 parts of water extract of Artemisia annua, and mix them evenly. (It should be understood that this botanical fungicide can be further processed into various water-soluble pesticide formulations.)

Embodiment 3

[0020] The fresh sisal leaves are chopped and extracted by alcohol extraction to obtain the alcohol extract of sisal leaves; the dried Artemisia annua is crushed and extracted by water extraction to obtain the water extract of Artemisia annua.

Abstract

A botanical fungicide and a preparing method thereof are disclosed. The fungicide includes 5-10 parts of matrine, 8-15 parts of an alcohol extract of sisal hemp leaves, 1-5 parts of a material named as Chinese characters 'Xiaochaihujian' by the inventor, 1-5 parts of arecoline and 10-20 parts of a water extract of artemisia annua. The matrine, the alcohol extract of sisal hemp leaves, the 'Xiaochaihujian', the arecoline, and the water extract of artemisia annua are composited into the efficient wide-spectrum nontoxic fungicide. The fungicide has good antagonistic effects on a plurality of germs, and has advantages of a high efficiency, a low cost, capability of being environmentally friendly, difficult generation of drug resistance, and no harm to humans and livestock.

Description

technical field [0001] The invention relates to a pesticide, in particular to a botanical fungicide and a preparation method thereof. Background technique [0002] According to statistics, the perennial area of ​​pests and weeds in my country is about 400 million hectares. Due to the use of pesticides, my country's annual direct economic loss is reduced by about 50 billion yuan. Chemical pesticides are widely used due to their high efficiency and speed. In my country, the annual demand is more than 1 million tons of preparations, and the annual spraying of chemical solutions is more than 100 million tons. The area of ​​chemical control has exceeded 2.8 billion hectares per year, and it is increasing year by year. . Due to factors such as high toxicity, high residue and irrational use of some chemical pesticides, while bringing people high agricultural yields, they also bring environmental pollution, excessive pesticide residues in agricultural products, ecological damage, th...
