Abstract

The invention relates to a Chinese herb control agent for crop powdery mildew and a preparation method thereof, and belongs to the technical field of ecological pesticide. The Chinese herb control agent for crop powdery mildew comprises Baijiu, sheath of sugarcane, sweet wormwood, tea seed cake, lycoris radiata herb, cannabis sativa leaves, Japanese banana, garlic, mint leaves, cassiabarktree branchlets, longhairy antenoron herb, heartleaf houttuynia, spanishneedles, litsea cubeba, radix bupleuri, purple perilla, common lophatherum herb and pelargonium graveolens. The finished product is obtained by the steps of weighing, mixed grinding, first cooking, second cooking, quality inspection and packaging and the like. The control agent takes Chinese herbs as main raw materials, has the efficacy of bacteriostasis and sterilization and is good in dispersibility, even in dissolution and fast in absorption, crops suffering from powdery mildew recover in three days after being applied with the control agent and are high recovery rate in one week after agent application, pests and diseases can be prevented effectively, the problem of pesticide residue of agricultural products is solved, and yield increase of crops can be realized.

Description

technical field [0001] The invention belongs to the technical field of ecological pesticides, and in particular relates to a Chinese herbal medicine control agent for crop powdery mildew and a preparation method thereof. Background technique [0002] Powdery mildew can occur from seedlings to adult plants, mainly damaging leaves, and sometimes stems, flowers, and fruits. At the beginning of the disease, white powdery mildew spots appeared on the leaves, and then gradually expanded. When the conditions are suitable, the white mildew spots can be quickly connected into pieces, and the leaves are covered with white powdery mold layers. Extending upward from the bottom leaves, sometimes many taupe spots appear on the lesions, seriously affecting photosynthesis, disturbing normal metabolism, causing premature aging and loss of yield. [0003] Powdery mildew is caused by the fungus of the subphylum Ascomycetes of melons. The fungus survives the winter on sheds and indoor crops wi...
