2018 New York and Pennsylvania Pest Management Guidelines for Grapes Now Available

The Pesticide Management Education Program (PMEP) at Cornell University is pleased to announce the availability of the 2018 New York and Pennsylvania Pest Management Guidelines for Grapes.

Written by Cornell and Penn State University specialists, this publication is designed to offer producers, seed and chemical dealers, and crop consultants practical information on growing and managing grapes in New York State and Pennsylvania. Topics include an overview of pesticide use and pest management in grapes; managing common grape disease, insect, and weed concerns; and sprayer technology. A preview of the Grape Guidelines can be seen online at

Highlighted changes in the 2018 Grape Guidelines include:

  • Updated pesticide options for economically important grape pests.
  • Information on how to use the Network for Environment and Weather Applications (NEWA) in grape integrated pest management.
  • Addition of grapevine leafroll disease to diseases of concern.

Cornell Crop and Pest Management Guidelines are available as a print copy, online-only access, or a package combining print and online access. The print edition of the 2018 Grape Guideline costs $31 plus shipping. Online-only access is $31. A combination of print and online access costs $43.50 plus shipping costs for the printed book.

The Grape Guidelines can be obtained through your local Cornell or Penn State Cooperative Extension office or from the Cornell Store at Cornell University. To order from the Cornell Store, call (844) 688-7620 or order online at

Lime Sulfur and Anthracnose

March 30, 2017

Anthracnose is a disease that I have seen mostly in new plantings of Cold-hardy cultivars in New York.  I happen to think that the conditions for it to spread and take hold (warm, humid springs) are more common farther south than here in NY, but it has appeared in several vineyards here in NY.

The fact is that in vineyards with a history of Anthracnose,  dormant lime-sulfur sprays are one of the principal ways of controlling it.

So I want to share with you Mike White’s article on Anthracnose.  Here is the link:  Wine Grower News #356 3-30-17-2e3o64u.

Lime-Sulfur is a very corrosive material (for painted surfaces), but very effective on dormant vines with existing Anthracnose.  Note that if you do not have a history of Anthracnose, you probably don’t need to do this.

Ohio State has a nice Anthracnose Factsheet.  We don’t have one in our Cornell IPM factsheets, because it has been very rare in commercial vineyards here in NY.
