ABSTRACT
The antimicrobial activity of nitropropane compound 791224 against several phytopachogenic fungi and Fusarium was studied in vitro. Its inhibitory effect on mycelial growth of Fusarium oxysporum f. sp. vasinfectum (Atk.) Snyder et Hansen and Fusarium graminearum Schwabe showed a much stronger than that on the other phytopathogenic fungi tested. The inhibition of 791224 on all tested Fusarium showed excellent. Its inhibitory effect values ranged from 54.2 to 100% at 5 ppm for 12 tested Fusarium whereas the respective values of carbendazim ranged from 0 to 27.3%. The inhibitory effect of 791224 at 5 ppm on Fusarium lateritium Nees reached to 100% whereas for carbendazim it was 0, i.e.100 times lower than that of 791224. In green house, the control efficiency of 791224 on Fusarium solani sothora japonico H. has been tested and showed a promising result.
