Cucumbers
In 2011 there were approximately 3,000 acres of cucumbers grown in New York worth $19 million (2011 Vegetable Summary). The majority of this production is for fresh consumption, including small scale retail operations, as well as wholesale production to serve larger markets throughout the Northeast U.S. In addition to open field production cucumbers are increasingly grown inside greenhouses and high tunnels. The crop, when unhindered by pests and diseases, can provide high yields within a short harvest window. Cucumber production in New York is increasingly under threat from the foliar disease Downy Mildew (Pseudoperonospora cubensis). Thus the Cornell Vegetable Program is collaborating with partners to conduct advanced on-farm research to enhance production and marketing of cucumbers, including the development of improved varieties suited for organic agriculture. Stay tuned for more information on this project. In the meantime check out results from our variety trials and grafting work with cucumbers below.Relevant Event

Cucurbit Weed Update
Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
As many of you know, we don't have a whole lot of post-emergent herbicides at our disposal for cu-curbits, and those that we do have are more grass herbicides then broadleaf materials. However, halosulfuron (Sandea or Profine), which is also one of our main broadleaf pre-emergent, is labeled and can be quite effective if used properly. If you used either Sandea or Profine pre-emergent even with another pre-emergent, we again would expect to see a few weeds such as Common Lambquar-ters and Ragweed start to breakthrough our pre-emergent herbicide barrier.

Thrips damage to High Tunnel Cucumbers
Amy Ivy, Vegetable Specialist

Thrips populations can explode, especially under the protective conditions in a high tunnel. Bio-controls can only help at the early stages, but there are a couple of other options for organic and conventional growers to try to bring this pest under control.
A Spring Tale of Springtails

The springtail is a flea beetle lookalike that typically feeds on decaying plant material, but under certain conditions may attack crops such as cucurbits. These tiny insects have been seen in several locations this past week feeding on cucumbers and garlic.

Cucumbers in High Tunnels
Amy Ivy, Vegetable Specialist
Eastern New York Commercial Horticulture
Cucumbers are an excellent high tunnel crop for spring, summer and fall production in New York State. Grown vertically, cucumbers take advantage of the space and light offered by a high tunnel. Cucumbers grown in this environment are of higher quality with higher yields. Very fast growing and yielding, they fit into crop plans that include winter greens easier than tomatoes, peppers or eggplants.
Responding to Hailstorms

While no one wants to think about the possibility of hail hitting their beautiful crops just as they start to respond to the heat and take off, the likelihood that we will see more hail seems pretty high. So let's talk about it.
Phytophthora Webinar 3: Management practices to reduce P-Cap on the farm
This recorded webinar features Dr. Meg McGrath for a discussion of fungicides for P-Cap, crop rotation strategies, and the use of biofumigants to control P-Cap in infected fields.
Webinar: How do I know if I have P-Cap in my Fields?
Laura McDermott, Team Leader, Small Fruit and Vegetable Specialist
Eastern New York Commercial Horticulture
The first in a 3-part series, this pre-recorded webinaris presented by Dr. Chris Smart, Cornell University.
Flooding in 2011 spread Phytophthora capsici into fields with no history of the disease. Growers who have not managed P. capsici previously could inadvertently and permanently spread the disease to additional fields and could experience high rates of crop loss due to improper management of the disease. Understanding of P. cap will reduce the probability of these negative outcomes on eastern NY farms.

Greenhouse Cucumber Variety Trial (2011)
Judson Reid, Extension Vegetable Specialist
Cornell Vegetable Program
The unheated greenhouse, or high tunnel, offers a vertical production environment suitable for crops such as indeterminate tomatoes and cucumbers. As it is a soil based system however, and passively heated, greenhouse cucumbers must be transplanted later in the spring than tomatoes, due to their intolerance for low root zone temperatures. However, cucumbers can provide good returns when grown in a high tunnel, given consistent pest control and matching variety performance with market demand. A variety trial of four greenhouse cucumbers was established in a cooperating high tunnel in the spring of 2011.

Grafting Cucumbers in High Tunnels
Judson Reid, Extension Vegetable Specialist
Cornell Vegetable Program
Soil based greenhouse and high tunnel production of vegetables has risen dramatically in New York recently. This season extension technology offers farmers an opportunity to target market price peaks and capitalize on rising demand for locally grown produce. Considerable attention has been given, justifiably, to tomatoes in these settings. Trials by the Cornell Vegetable Program confirm that cucumbers can also be grown at a profit in tunnels.
As production continues in the same soil beds, risk of root-zone diseases and soil nutrient deficiencies increase. Grafting, the combination of two separate cultivars into one plant, could be a solution to these challenges. Evaluations of grafted tomato by the Cornell Vegetable Program revealed several advantages. This project endeavored to graft cucumbers onto a fig leaf gourd (Cucurbita ficifolia) for increased yields and cold hardiness.
