2017 Cucurbit Downy Mildew Management Guidelines

Last Modified: July 5, 2017

2017 Cucurbit Downy Mildew Management Guidelines
From Margaret McGrath, Plant-Microbe Biology Section, SIPS, Cornell University
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.

The links below contain more information on resistant varieties, developing a diversified fungicide program and timing your sprays, and recommended targeted and protectant fungicides.

Additionally, you will find information for organic management of cucurbit diseases 
through biopesticides and fungicides for vegetable crops and herbs.

Eastern Broccoli Market Opportunity Assessment

Is there an opportunity for New York growers and marketers to invest in broccoli production and distribution as a way to diversify and strengthen their businesses, while adding jobs, dollars, and resilience to the economy and rural communities?

The Eastern Broccoli Market Opportunity Assessment for New York State sought to answer this very question. The study was made possible by the initiative of three partner organizations: Hudson Valley AgriBusiness Development Corporation, Red Tomato, and the Eastern Broccoli Project, with funding provided by Empire State Development.


Essentials of Farm Food Safety for Farmworkers

Call to Schedule a Tailored Training for Your Farm Workers
This is a training is brought to you by the CCE Cornell Vegetable Program. Workers will learn the importance of farm food safety and the ins and outs of how it works on the farm and field.

This training aims to cover many of the required worker training topics set forth by GAPs (Good Agricultural Practices and FSMA (the Food Safety Modernization Act), or other 3rd party auditing programs. This training series primarily focuses on training farmworkers in the produce industry. Because Food Safety is a company-wide responsibility, we invite all farm employees to participate in this training. Each farm has unique operating practices but the basics of food safety are critical skill set needed for workers to have if a smoothly operating food safety program is going to work on your farm. Topics covered include:
  • Understand the role of worker training in ensuring food safety on your farm
  • Cover all the important points required for training
  • Identify challenges to consider when training workers and discuss solutions
  • Cover required records for training
  • Introduce resources available to managers to assist in training
  • Why is farm food safety important?
  • How does produce become contaminated?
  • What are the signs that you or a coworker are ill?
  • How can you minimize food safety risks on the farm?
  • What should you do if you see a risk you cannot reduce or eliminate?
  • And much more
We can provide a tailored training for your workers through an online program before the season starts or combine workers with another farm to do a larger training. Contact Robert Hadad for more information.
