乙蒜素对茶树苔藓地衣防治效果研究OA

In order to explore safe and efficient biological control technologies for tea plants,field experiments were conducted to study the control effects of different concentrations(600 fold diluted solution,700 fold diluted solu-tion,800 fold diluted solution,900 fold diluted solution)of ethylicin(a plant-based biomimetic fungicide)on moss and lichen and their impacts on tea yield.Overall control effects at 10 and 20 days after treatment with 700 fold di-luted solution of ethylicin were above 91%.This concentration of ethylicin effectively reduced the negative impact of moss and lichen and increased tea yield by 16.74%compared to the untreated treatments,with a remarkable eco-nomic benefit.
