Disease-suppressive crops work in multiple ways: by not being a crop host to the disease, by actively lowering pathogen levels, and by boosting soil health so the overall growing environment is more resilient to disease. Robert Larkin, USDA-ARS research plant pathologist, joins us to discuss the different ways crops can lower disease pressure, what farmers in Maine are doing, and all about soil health more broadly.
