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

Tenuta points… Read More
The rain has come, and the corn crop is advancing fast. The crop is between tassel and silking stages, and the concern now is how to manage the crop for silage production. Will disease have an impact on the feed quality? Here to answer that is Albert Tenuta, OMAFRA plant pathologist, who joins Bernard Tobin… Read More
While it’s important to stay current on new and emerging diseases of the corn crop, it’s still important to keep tabs on the old standbys, such as northern corn leaf blight. “We know the weather’s been favourable for diseases, and we get lots of calls on that,” says Alberta Tenuta, plant pathologist at OMAFRA. There’s… Read More
Some Ontario edible bean and soybean fields are being hard hit by root rots, causing large patches of dead, dying, or highly stressed plants. The recent hard rains in some areas of the province have favoured root rot infection. Depressions or areas of high compaction or poor drainage tend to show the worst symptoms. Poor… Read More
