Intensity of Anthracnose in resistant varieties (PIWI) in the high altitude regions of southern Brazil
The objective of this study was to evaluate the different degrees of tolerance to Anthracnose infection in three PIWI varieties (Cabernet Cortis, Regent and Bronner) compared to the Cabenert Sauvignon variety. The experiment was conducted at EPAGRI Experimental Station, located in the city of São Jo...
