Video: Downy Mildew
Downy mildew is a potentially devastating disease to cucurbits. It usually affects cucumbers and cantaloupes first; later in the season it can be found on summer squash and zucchini. During some seasons, downy mildew can spread to winter squash and watermelons. Growers need to be monitoring their fields. This short video shows the different stages of the disease and possible outcomes if it is not controlled.

Upcoming Events
Niagara Region Vegetable Meeting
August 14, 2024
Clarence Center, NY
We'll start this meeting off at Root Down Farm to hear late season disease management updates in peppers and cole crops, plus current best management practices to limit fungicide resistance. Potato variety recommendations and disease control questions in potatoes will be addressed.
Then we'll head to Kreher's beet field to view and discuss alternative weed control technologies. The beet field is an on-farm demonstration of various flame weeding protocols in comparison with stacked tool cultivation equipment. One or two weeding robots will be on-hand for live demonstrations and discussion of the technology's current abilities and future potential. We'll also cover industry updates and a review of late summer disease management in squash.
2.0 DEC credits will be available in categories 23, 1a, and 10.
