Cultural of Fusarium verticillioides

Maize ear rot caused by F. verticillioides which is prevalent on maize under Punjab conditions. The symptoms appear as white-pink fungal growth and causes “starburst” pattern of white streaks on the kernels. Thirty Fusarium isolates were isolated from the infected maize plant from different agro-chemical zones of Punjab.

Maize Post flowering stalk rot causing caused by Fusarium verticillioides is major disease and causing yield loss up to 34 per cent. Different liquid media supporting the growth of the different isolates of fungus was observed. Among the eight-liquid media tested for the dry mycelial weight and sporulation of six isolates of Fusarium stalk rot pathogen (F. verticillioides), Isolate FV-3 yielded highest dry mycelial weight of 787.66mg, followed by FV-2 (647.66mg), FV1(581.00mg), FV-5 (451.00mg), FV-6(421.00mg) and FV7(277.66mg) in Takahashii’s broth.

This study aimed to evaluate the fungi toxic effect of palmarosa essential oil (Cymbopogon martinii) on mycelial growth of Fusarium verticillioides in vitro and treatment of corn seeds. For the in vitro experiment the essential oil was added to the culture medium and poured into Petri dishes, using seven different oil concentrations (0.0125, 0.025, 0.05, 0.1 and 0.2%), 0.0% was the negative control, and we used Thiram as a positive control. Discs of culture medium with fungal mycelium were inoculated into the center of the plates and incubated for seven days at 27 ± 2°C.
