Squash- Winter

Squash- Winter New York State has a strong industry growing winter and summer squash with over 4,000 acres produced in 2014 with a value of over 31 million dollars. There are many different types of winter squash that are grown including hubbard, buttercup and spaghetti, but butternut and acorn types are the two dominant ones for production. Winter squash is also sold for wholesale and fresh market use. There is also a significant amount of butternut squash that is cut and peeled and repacked and sold through grocery stores. Powdery and Downy Mildew, and Phytopthroa blight are the major diseases we are concerned with.

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

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.

Cold Storage Chart and Reference Guide to Commercial Vegetable Storage

Commercial vegetable growers will find a Cold Storage Chart by crop type with temperature and relative humidity recommendations. The maximum number of weeks that the crop can be held under ideal conditions is provided as well.

Adapted from the USDA Bulletin #66, The Commercial Storage of Fruits, Vegetables, and Florist and Nursery Stock, growers will find information on quality, grading, sizes, and packaging, chilling and storage, and post-harvest pathology of vegetables.

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.

Small-Scale Fresh Mkt Potato Variety Trial Results

This year, the Cornell Vegetable Program planted a potato variety trial focused on commercially available fresh market potato varieties, with the small-scale potato grower in mind. This trial allowed us to test different varieties of potatoes that might be of interest to consumers at farm markets and see how well they perform in a western NY climate. 

We've posted a brief overview of our results on the Potato page.

If you would like the full report (PDF with photos and yield data) emailed to you, email Margie Lund.

New Ag Climate Factsheet Released

The intersection of agricultural production and greenhouse gases is gathering increasing attention. This is an opportune time to consider how vegetable production interacts with carbon sequestration and greenhouse gas emissions, and how using cover crops may alter this picture.

The factsheet, Greenhouse Gases and Soil Organic Carbon in Vegetable Production and the Role of Cover Crops, written by Zach Spangler, Ag Climate Resiliency Specialist with CCE Harvest NY, and Elizabeth Buck, Fresh Market Vegetable Specialist, CCE Cornell Vegetable Program, discusses:
  • Sequestration of atmospheric carbon in agricultural soils as soil organic carbon (SOC). Is vegetable production impacting SOC?
  • Net greenhouse gas emissions of carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4) from the soil.
  • Impact of cover crops on soil organic carbon, nitrous oxide emissions, and other GHG emissions.
