EFFECT OF DIFFERENT CONCENTRATIONS OF BENOMYL AND PCNB ON THE RADIAL GROWTH OF Fusarium solani AND Pythium sp. IN VITRO
Keywords:
Fusarium, Pythium, benomyl, PCNBAbstract
The experiments were carried out at Laboratory of Phytopathology of the Escola de Agronomia of the Universidade Federal de Goiás, in the year of 1997. The fungi Fusarium moniliforme and Pythium sp. were treated in cultural medium with benomyl and PCNB in the concentrations of 10, 25, 50 e 100ppm. The radial growth of the fungi demonstrated that benomyl was efficient against Fusarium, but not against Pythium sp. The same was also observed with PCNB. Although less efficient than benomyl, this product reduced radial growth of Fusarium in more than 50%. The increase of PCNB concentration reduced Fusarium growth progressively.
KEY-WORDS: Fusarium; Pythium; benomyl; PCNB.
