Abstract

The invention discloses a botanical bactericide for preventing sweet potato wilt and a preparation method thereof. The botanical bactericide is prepared from, by weight, 20-30 parts of pyrethrum extracts, 10-20 parts of fennel extracts, 5-20 parts of cortex pseudolaricis extracts, 10-20 parts of fructus cnidii extracts, 10-15 parts of herba artemisiae scopariae extracts and 10-15 parts of fortune eupatorium herb extracts. The botanical bactericide is good in sweet potato wilt prevention and treatment effect and free of toxic and harmful effects on human beings and livestock.

Description

technical field [0001] The invention relates to a fungicide, in particular to a botanical fungicide for preventing and treating sweet potato wilt and a preparation method thereof. Background technique [0002] Sweet potato wilt aliases: wilt disease, vine cut disease, vine blight, stem rot, etc. Its pathogen is called Fusarium oxysporum sweet potato type, which belongs to the fungus of the subphylum Deuteromycota. Mainly damage stems and tubers. The leaves at the base of the infected main stem at the seedling stage turn yellow first, the base of the stem expands and cracks longitudinally, exposing the pith, and the vascular bundles can be seen to turn dark brown in cross section, and the cracks are fibrous. The pedicle of the infected potato is rotten, the upper part of the diseased potato is cut crosswise, and the vascular bundles are brown spots. The leaves of the diseased plant gradually turn yellow from bottom to top and then fall off. Finally, the whole vine withers an...
