CONTROL DE Botrytis cinerea Pers. (Telomorfo: Botryotinia fuckeliana De Bary) EN ROSA CON EXTRACTOS DE VID SILVESTRE

Abstract

In Mexico, the floriculture industry has grown in the last decade in surface, in new species and in its intensive management in area highlighting the rose bush, as the main species that is exported, its cultivation is damaged by a disease called blight by B. cinerea. Its control depends only on the use of fungicides of the benzimidazole type, highlighting the benomyl and little has been tried with the use of fungicides of botanical origin, a possible alternative are the extracts of wild vine that contains high amount of phenols. Therefore, the present work was established with the objective of evaluating the wild vine extract to control B. cinerea in rose. Three doses of the phenolic extract obtained from the accession of wild vitis obtained by the percolation method from the macerated material with ethanol, as well as a control of synthetic origin were evaluated. The established inoculum was provided by the ICAMEX laboratory. Four repetitions were established for each treatment under a randomized block design. The results indicated that the 80% dose reduced the severity of Botrytis spp. in the cultivar of rosa Santa fe variety, as well as the smaller area under the curve of the progress of the disease. The doses at 40 and 100% showed no control effect behaving the same as the control.
