The sweet spot for fungicide use

Variety resistance and the level of disease pressure impacts fungicide effectiveness

By Lisa Guenther October 13, 2015

Early fungicide applications reduce blackleg severity when disease pressure is high and the varieties lack resistance, a researcher told delegates at the International Rapeseed Conference in Saskatoon. But fungicide has little effect when varieties are resistant or moderately resistant, he said. “We need to find kind of a sweet spot with fungicide use,” said Dr. […] Read more
