Vegetable Pest and Cultural Management Field Meeting - Seneca County
August 12, 2015This course will demonstrate pest management in fresh market vegetables in both field and greenhouse (high tunnel) vegetables; primarily for those growing for wholesale auction. A hands-on demonstration of weed, insect and disease identification in vegetables including management options such as inter-row cover crops, grafting and where appropriate, spray options will be used to educate growers. Judson Reid, Senior Extension Associate with the Cornell Vegetable Program will instruct participants and facilitate peer-based learning.

Late Blight Confirmed in WNY CountiesLate blight has now been confirmed in commercial potato and/or tomato fields in the following counties: Genesee, Livingston, Monroe, Steuben, Wayne, Wyoming, Yates, Tioga, Oneida, and Ulster. The LB strain was determined to be US-23 in these counties, sensitive to Ridomil (mefenoxam fungicides). All tomatoes and potatoes in Western NY and the Finger Lakes Region are at high risk of infection!
Continuing frequent rainfall has been extremely favorable for the development of late blight (LB). LB forecast programs have been indicating extremely high risk of disease development week after week. Scout fields, especially low spots, protected areas, etc. twice a week. Growers and gardeners should destroy all potato culls and volunteers now. All tomato and potato growers should be applying fungicides on a regular basis, at no longer than 7 day intervals. At some locations less than a 5 day spray interval may be needed to protect potatoes and tomatoes (Alternate fungicides; follow label directions!) according to the LB Decision Support System (DSS) forecast. Organic growers should also be applying a fungicide regularly. There are copper formulations approved for organic production. Fungicides differ in how long they will provide protection from infection.
Cucurbit Downy Mildew Confirmed in WNYCharacteristic disease symptoms are angular, pale green areas bounded by the leaf veins. They will turn yellow and later necrotic. Under high humidity conditions sporulation will occur on the lower leaf surface. Apply targeted fungicides tank-mixed with protectant fungicides weekly and alternated among available modes of action (FRAC code), starting when there is risk for a specific crop based on forecasting program. Refer to the Cornell Vegetable Guidelines for a complete list of products available. For more information, contact Robert Hadad or Darcy Telenko.
Herbicide Charts for Vegetable Crops AvailableThe Cornell Vegetable Program has compiled herbicide charts for control of weeds in the following crops in New York in 2015: beans (snap & dry beans), beans (lima), beets, cabbage, carrots, cucurbits, peas, peppers, and sweet corn. While these reference charts are handy, it is critical to read the labels thoroughly.
2015 Cornell Vegetable Guidelines AvailableThe 2015 edition of the Cornell Commercial Vegetable Production Guidelines is now available. This annual publication provides up-to-date vegetable crop production information for New York State. It has been designed as a practical guide for vegetable crop producers, crop consultants, and ag suppliers. In addition to the annually revised pesticide and crop production information, this edition also includes revised soil management guidelines; adding mode of action/group numbers to all pesticide listings; updated Colorado potato beetle resistance management information; totally revised organic vegetable production information; and the addition of western bean cutworm in sweet corn and western flower thrips in tomatoes as pests of concern.
NOTE: Beginning in 2015, Vegetable Guidelines will no longer be offered for free online. Instead, you will have the option to purchase just a print copy ($33 plus shipping), online version ($33), or a bundle of a print copy plus online access ($46 plus shipping).
