Popis: Made available in DSpace on 2022-04-28T18:56:34Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-01-01 Gummosis is among the main fungal diseases of the citrus. It is caused by Phytophthora sp. and usually shows up in the lap of the plant, provoking rottenness and gum exudation, and expands causing the plant death for constrictions in the cambium or phloem which interrupts the descending flow of sap. The objective of this work was to evaluate the antagonistic in vitro activity of Trichoderma spp. to the fungi Phytophthora citrophthora. Phytophthora citrophthora was exposed to five environments of antagonism (without antagonist and with four strains of Trichoderma viride, T. virens, T. harzianu and T. stromaticum). The in vitro essay was accomplished through the method of paired cultures. A completely randomized desing was used with five treatments and three replications, and each plot was represented by three petri dishes. The isolates of Trichoderma demonstrated significant effect in the inhibition of the mycelial growth of the fungi Phytophthora citrophthora, and the fungi Trichoderma stromaticum presented larger antagonism to the fungi P. citrophthora while the T. harzianum presented antagonism smaller.
