Controle de fitopatógenos do solo com materiais vegetais associados à solariza？？o

the association between previous incorporation of vegetable material and soil solarization is a promising technique for control of several phytopathogens. the objective of this work consisted in the investigation of materials vegetable that are promising to produce fungitoxic volatiles capable of inactivating the resistence structures of soil plant pathogens. three kg/m2 of vegetable materials were incorporated under field conditions, and the survival of four fungal species (fusarium oxysporum f. sp. lycopersici race 2; macrophomina phaseolina, rhizoctonia solani ag-4 hgi and sclerotium rolfsii) was evaluated against four fresh materials vegetables, ground and incorporated into the soil (leaves and branches of broccoli, eucalyptus, castor bean, and wild cassava). control was evaluated through of the analysis of the survival of structures in a specific semi-selective medium, during four periods (7, 14, 21 and 28 days from the beginning of the experiment). temperature values were monitored by a datalogger type cr23x (campbell scientific), and co2 and o2 percentages were monitored with a gas analyzer equipment (testo 325-1). the association between incorporation of vegetable materials with soil solarization inactivated f. oxysporum f. sp. lycopersici race 2, m. phaseolina and r. solani. the fungus s. rolfsii was the only that didn't present 100% of control with solarization more castor bean during the studied period. the incorporation of cassava followed by solarization provided the control of all fungi studied in less than seven days from the installation of the experiment, and was as efficient as broccoli in the eradication of these soil-borne plant pathogens.
