Abstract

The invention discloses a control method for colletotrichum gloeosporioides penz. The control method comprises the following steps: sterilizing seeds, carrying out soil treatment, carrying out pest control, weeding, pruning and carrying out tree trunk treatment. By adopting a comprehensive control method, quantity of anthrax fungi in anise field pieces can be fundamentally reduced, damage degree can be alleviated, occurrence and transmission routes can be controlled, and finally the aim of comprehensively controlling the colletotrichum gloeosporioides penz is achieved. The control method disclosed by the invention has the advantage that control effect on the colletotrichum gloeosporioides penz can reach more than or equal to 90% and is much higher than the control effect of the conventional drug, so that the control method disclosed by the invention has a broad market popularization prospect.
