The invention discloses a green and environment-friendly plant fungicide and a preparation method thereof. In parts by weight, it comprises the following components: 3-8 parts of astragalus polysaccharide, 2-6 parts of lily polysaccharide, 3-7 parts of golden cherry polysaccharide, 2-5 parts of tea polyphenols, 3-5 parts of menthol, 1-4 parts of cinnamaldehyde, 1-4 parts of citronellal, 3-6 parts of linalool, 1-3 parts of plumbagin, 4-4 parts of vanillic acid 6 parts, 4-6 parts of rosmarinic acid, 1-3 parts of antioxidant, 3-5 parts of bactericidal activator, and 30-60 parts by weight of water. Compared with the prior art, the plant fungicide can not only effectively kill most of the harmful fungi in the soil, but also kill insects, especially the root-knot nematodes of crops have a certain control effect; Crops develop drug resistance; the introduced bactericidal activator can enhance its bactericidal effect, and at the same time can reduce the phytotoxic effect of the bactericide on the plant itself, which is beneficial to improve the resistance of the plant itself. |
