Efficacy tests on fungicides of Phyllosticta negundinis in laboratory.
Abstract
In recent years, sugar maples leaf blight becomes more serious in Harbin, and its pathogen is Phyllosticta negundinis. Sixteen fungicides were tested for efficacy against the leaf spot disease of sugar maples. The results showed that all the sixteen fungicides could significantly inhibit mycelial growth, while prochloraz, carbendazim.mancozeb, mancozeb and mancozeb.dimethomorph proved to be the most effective fungicides, with their inhibitory rates up to 100%, which followed by flusiazole.carbendazim and difenoconazole.
