Squash - Summer
New York State has a strong industry growing winter and summer squash with over 5,000 acres produced in 2011 with a value of over 43 million dollars. A lot of summer squash is sold on the wholesale market, but nearly all of it is consumed fresh. Zucchini and Summer /Yellow squash are dominant types of summer squash grown in the area. Powdery and Downy Mildew, and Phytopthroa blight are the major diseases we are concerned with. Viruses are of major importance for summer squash growers and have led to plant breeders and seed companies to develop and release many different virus resistant varieties.Relevant Events

Growing for Wholesale: Grading and Packing Guidelines by Crop
Grading and packing guidelines are now available for 18 commonly grown specialty crops in NYS: romaine lettuce, acorn squash, broccoli crowns, Brussels sprouts, sweet corn, green peppers, cucumbers, green cabbage, red cabbage, savoy cabbage, cauliflower, eggplant, green beans, jalapenos, poblanos, Hungarian hot peppers, summer squash, and zucchini.
Video: New York State Produce Auctions
Currently, there are 8 produce auctions in New York State. These auctions are aggregation points that allow local farmers to sell their produce in wholesale lots to buyers from across the region. To document the economic impact of produce auctions on agriculture, local businesses, family farms, and produce buyers, the Cornell Vegetable Program worked with Harvest New York to survey top sellers and buyers.
A new Cornell Vegetable Program video shares general information about produce auctions, how buyers and sellers use the auctions to expand their businesses, and how local communities benefit from them.
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.
2017 Cucurbit Downy Mildew Management Guidelines
From Margaret McGrath, Cornell
Producing a high-quality cucurbit crop necessitates effectively managing downy mildew. This foliar disease is common in the northeast because the pathogen produces a large quantity of asexual spores that are easily dispersed long distances by wind, which enables it to spread widely. There has been no evidence that the pathogen is surviving between growing seasons where winter temperatures kill cucurbit crops (outdoors above the 30th latitude); however, recently both mating types have been found, albeit typically on different cucurbit crop types, thus there is the potential for the pathogen to produce oospores (sexual spores) that could enable the pathogen to survive in northern areas of the USA. The downy mildew forecasting program has documented based on downy mildew occurrence movement of the pathogen throughout the eastern USA each year via its wind-dispersed asexual spores. The pathogen does not affect fruit directly; however, affected leaves die prematurely which results in fewer fruit and/or fruit of low quality (poor flavor, sunscald, poor storability).
The most important component of an effective management program for downy mildew is an effective, properly-timed fungicide program. And the key to that is applying mobile fungicides targeted to the pathogen starting when there is a risk of the pathogen being present. Mobile (or translaminar) fungicides are needed for control on the underside of leaves. Each year there often are changes to the fungicides recommended as the pathogen develops resistance or new products are registered. Because these fungicides have targeted activity, additional fungicides must be added to the program when there is a need to manage other diseases such as powdery mildew. Most targeted fungicides effective for downy mildew are also effective for Phytophthora blight.
Guideline Tools: Weed Management in Cucurbits, 2015
Darcy Telenko, Extension Vegetable Specialist
Cornell Vegetable Program
This reference sheet lists the herbicides that are labeled for cucurbits in New York and which species are controlled, as well as other important considerations and photos of weeds. While this is a handy references, it is critical to read the product labels thoroughly.
Copper Fungicides for Organic Disease Management in Vegetables
There are several different copper fungicides approved for use in organically-produced crops. Copper fungicides are important tools for managing diseases that cannot be effectively managed with cultural practices alone.
Responding to Hailstorms
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
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.
