Abstract

The invention relates to the field of pesticides and in particular relates to a biological preparation for preventing and treating astragalus membranaceus powdery mildew and a preparation method of the biological preparation. The biological preparation for preventing and treating astragalus membranaceus powdery mildew is characterized by providing components A, B and C which are prepared from hot pepper, garlic, pepper, ailanthus altissima swingle, gelsmium elegans, purslane, tobacco, golden cypress, celastrus angulatus, cacumen biotae, melia toosendan and birthwort, sequentially spraying the components A, B and C on the astragalus membranaceus when the powdery mildew occurs in the astragalus membranaceus growth period to remove the astragalus membranaceus powdery mildew germs. The biological preparation for preventing and treating astragalus membranaceus powdery mildew has the advantages that the biological preparation takes Chinese herbal medicines as the raw materials, has the inhibiting and killing functions for fungi through manners of contact poisoning, stomach poisoning and inward absorbing, is free of harm to people and livestock and pollution to the environment, simple in formula, convenient to use and capable of effectively preventing and treating a variety of diseases and insect pests.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a biological bactericidal preparation for preventing and treating astragalus powdery mildew and a preparation method thereof. Background technique [0002] Astragalus perennial herb, 0.5-1.5 meters high, straight and long root, cylindrical, slightly woody, 20-50 cm long, root head diameter 1.5-3 cm, surface light yellow to dark brown. Stem erect, branched, villous, odd pinnate compound leaves alternate, base of petiole cuneate entire, both sides covered with white villous, without petiole. Racemes axillary, slightly longer than leaves, with 10-15 flowers, small flower roots shortly covered with black bristles, bracts narrow; calyx and lobed tube; butterfly-shaped corolla light yellow, about 1.6 cm long, flag petal Triangular-obovate, wing petals and keel petals have handle-shaped long claws. Astragalus has the characteristics of liking the cold climate, strong drought tolerance and fe...
