Late blight in US growing regions

Reports of late blight in the southern US (Louisiana, Florida, Maryland) have the vegetable industry on alert.  In recent days, late blight has also been found on tomato transplants in a greenhouse in Pennsylvania.

Growers in Ontario should scout their tomatoes carefully for signs of late blight.  If inoculum reaches the area, the risk of an outbreak is highest during cool, wet weather.

If late blight symptoms are found, a fungicide program needs to be implemented immediately.  Watch for more information in future updates.

Stop Moving Soil

by Anne Verhallen, Soil Management Specialist, OMAFRA – Ridgetown

The early spring weather and dry soil conditions have tempted a number of people into early tillage with predictable results – wind erosion!  The best way to prevent wind erosion is to keep soil covered; at least for as long as possible.  Weather records tell us that the chance of a wind erosion event drops dramatically as the calendar moves into late May and early June – but April and early May are windy almost guaranteed.
