It's easy for growers to get excited in July when the rows close in their soybean crops and lush canopies are intercepting sunlight, generating high photosynthesis rates and building big yield potential. But there could be trouble ahead if sclerotinia — the pathogen that influences white mould — infects flowers and allows the yield-robbing disease... Read More

Tar spot is taking a bite out of yields in some Ontario corn fields but there is hope that growers will have effective tools to manage the leaf disease. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen has been delivering yield hits ranging from 20 to 60 bushels per... Read More
