IN VITRO TOXICITY OF HNO2 AND NH3 IN PHYTOPHTHORA CAPSICI MYCELIUM GROWTH
In order to determine the toxic effects of HNO2 and NH3 solutions on Phytophthora capsici mycelium growth, experiments were carried out in vitro under differents concentrations (from 0 to 106 μM HNO2 and from 0 to 471 μM NH3) and treatment duration (6, 15 and 24 h). Cumulated growth recorded 3 days after HNO2 treatment showed a lethal effect at 96 μM for 6 h of treatment, at 42 μM for 15 h, and between 21 and 42 μM with 24 h of treatment.
In contrast, NH3 solutions from 0 to 471 μM had no lethal effect on mycelium growth, though concentrations from 235 μM had inhibitory effects on growth.
