Produce Pages is a monthly newsletter of the Eastern New York Commercial Horticulture program, and is published October through March. It provides readers with information on upcoming meetings, pesticide updates, pest management strategies, cultural practices, marketing ideas and research results from Cornell University and Cornell Cooperative Extension.

Produce Pages
is only available to enrollees in the Eastern New York Commercial Horticulture program.

Additionally, the Eastern New York Commercial Horticulture program produces multiple Weekly Updates, seasonal weekly newsletter that are commodity specific. It is more focused on local conditions, crop development, pest activity and control strategies. It is available through enrollment in our program.

Cucurbit Downy Mildew (CDM) Indentified

Please be aware that Cucurbit Downy Mildew (CDM) has been identified today (Tuesday, July 18 2017) in the Mid- Hudson Valley, specifically Dutchess County. This is a fast moving and very destructive disease as windblown spores from this infection site are a primary source of infection for other cucurbit plantings in the area. Spores are easily dispersed long distances. All cucurbit types may be affected, with cucumbers being the most sensitive followed by melons. According to the CDM forecasting program, southern NY was included in the areas with a "high risk" of spore deposition and infection back on July 7th , 11th and 13th, so with the weather conditions we've had symptom development is pretty much on target (7-10 days). CDM Forecasting model can be accessed at: http://cdm.ipmpipe.org/ Please note that we had a moderate risk yesterday with a low risk for spread today (Tuesday).

If you are in the Hudson Valley or another high risk area, now is the time to apply mobile (systemic, translaminar) fungicides with an active ingredient that specifically targets DM. For conventional growers I have seen where a tank mix of Curzate plus Ranman or Zampro plus a protectant like chlorothalonil (Bravo, Initiate etc.) has done a very good job. Curzate provides some kickback or burnout activity but does not have much residual which is why it needs to be tank mixed with a second mobile fungicide or another application needs to be made 3-4 days later. Mobile fungicides are needed to control the disease from developing on the UNDERSIDE of the leaf. Fungicides should be re-applied according to disease severity and label instructions (keep pre harvest intervals in mind, maximum use rates and please rotate chemical classes using the FRAC codes found on all the labels. More information including risks forecasts and fungicide recommendations can also be found in the CCE ENYCHP Weekly Vegetable Updates

According to Cornell Pathologists Margaret McGrath, one of the better organic products evaluated is Timorex Gold (Tea Tree oil) and is labeled in NYS (click the name to see a copy of the label). See label for the rates and note that there is a 48-hour re-entry interval and do not apply within 48 hours of harvesting. Do not spray during the warm hours of the day and in hot seasons with temperatures above 95F (35C) and Do not apply this product through any type of irrigation system. Alternate with copper every 5-7 days.

If you suspect CDM please contact your local CCE ENYCHP educator for confirmation and help in establishing a treatment plan.

More information can be found on Cornell Pathologists Margaret McGrath's bulletin on "Effectively Managing Cucurbit Downy Mildew in NY in 2017 "for details. http://vegetablemdonline.ppath.cornell.edu/NewsArticles/Cucurbit%20Downy%20Mildew%20MGT-NY-2017-McGrath.pdf

Growers looking for information on OMRI/ organic approved products for downy mildew please see: "Biopesticides for Managing Cucurbit Crop Diseases Organically" also complied by Margaret McGrath.

Welcome Jim Meyers: New Viticulture Specialist!

Jim has been working with wine grapes for 10 years, first as a Viticulture Ph.D. student at Cornell then as a Research Associate. Prior to coming to Cornell, Jim studied Chemistry and Biology (B.S. West Chester University of Pennsylvania), Computer Science (M.S. Brown University), and had a successful career as software technology entrepreneur. This background is reflected in his viticultural research which has focused on computational tools for mapping canopy and vineyard variability, quantifying relationships between variability and fruit chemistry, and optimizing efficiency of vineyard operations. As an Extension Associate, Jim will continue some of these research activities while also looking for new projects that provide targeted benefits to appellations in Eastern New York. Jim will kick off his new appointment by visiting growers at their vineyards to gather first hand knowledge of the sites and to discuss vineyard operations, goals, and challenges. Building a complete catalog of vineyards in a territory that runs 300 miles along the Route 9 corridor may take a little while, but Jim feels that the effort will lay a solid foundation for future program activities while also clearly differentiating the needs of each appellation.

New Resources for Berry Crops

Berry Crop Diagnostics Tool - Much information exists on controlling plant pests and problems, but one must first identify the cause before intervention can occur. This diagnostic tool was developed to assist the student, grower, and extension educator in identifying potential causes of plant problems in berry crops

White Rot Update

NOW AVAILABLE: White Rot Fact Sheet: Click Here

Earlier in June I sent a garlic sample to the diagnostic lab hoping that I was wrong. The sample was covered in small black sclerotia, the size of poppy seeds, and white fungal hyphae crept up the stem. The results, unfortunately, matched the field diagnosis: White Rot. Within a couple days additional calls came from up and down the Hudson Valley as well as one in Western NY with similar suspicions. These samples have also gone to the lab for verification, but it looks like the latest pest to move back into the state is this nasty fungus. 

White Rot, Sclerotinia cepivorum, decimated the onion industry in New York in the 1930's before being eradicated through careful management. More recently, in 2003, it infected 10,000 acres of garlic in California, leading to the abandonment of some garlic fields and adoption of strict containment rules. White rot has been confirmed in Northeastern states over the last decade as well, with New York being one of the last to discover the disease.

The primary reason that White Rot is such a concern is because the sclerotia, or reproductive structures, can remain dormant in the soil for up to 40 years, attacking any allium crop planted into the soil under favorable conditions. This spring was ideal for infection due to the period of cool, moist weather we had. Optimal temperature for infection is 60-65 degrees F, but infection can occur anywhere from 50-75 degrees F.
Once garlic has white rot, it generally declines rapidly. Leaves will yellow and the plant will wilt, not unlike a severe fusarium infection. However, unlike with fusarium, white rot infected bulbs are covered in black sclerotia and white fungus. To add to the confusion, another disease CAN look similar. Botrytis also causes black sclerotia and white fungal growth. However, Botrytis sclerotia are quite large, often larger than a pencil eraser.

So, what do we do now? We're still working on long-term management strategies, but the most important steps to take now are vigilance when culling (look at the plants you are pulling for symptoms like you see in this article, and if they are present, call us to take a sample and have the disease verified) and, if you see anything suspicious, reduction of movement of inoculum. The main ways diseases get moved around are by dumping culls (compost, field edges, etc) and my moving soil on equipment. Throw away your culls, and wash equipment that may have come in contact with suspicious garlic or the soil it is growing in. Everything from cultivation equipment to harvest bins should be cleaned. 

We will keep learning about this disease and will keep sending out information, particularly to help you make decisions about what to sell and buy. For now, remember that the west coast has learned to manage the disease, and we will too. -Crystal Stewart, ENYCHP
