As the largest county in New York State St. Lawrence County is home to a well established agricultural industry. With over 400,000 acres being farmed, 25% of the land mass in St. Lawrence County is dedicated to agriculture. The County ranks #1 in the state hay production in the United Sates for dairying in a February 2000 survey by Dairy Today Magazine.

*Late Blight is worse than ever this year.  One of the most visible early symptoms of the disease are brown spots (lesions) on stems. They begin small and firm, then quickly enlarge, with white fungal growth developing under moist conditions that leads to a soft rot collapsing the stem.

Classic symptoms are large (at least nickel-sized) olive-green to brown spots on leaves with slightly fuzzy white fungal growth on the underside when conditions have been humid (early morning or after rain). Sometimes the border of the spot is yellow or has a water-soaked appearance. Spots begin tiny, irregularly shaped and brown. Firm, brown spots develop on tomato fruit.

Check your plants regularly.

Below are some helpful information sheets.  If you have further questions contact Steve Vandermark at the Extension office.  (315)379-9192 ext. 232.
