Organic

OrganicAccording to the Northeast Organic Farming Association of NY (NOFA-NY), organic farming "seeks to maintain and improve the productivity of the land by encouraging and enhancing natural biological processes. Organic farmers nurture healthy plants by working to create a foundation of healthy soil. Great attention is paid to nurturing the soil with composts, cover crops, rock minerals and natural fertilizers. Plant disease and pests are controlled through the use of crop rotations, resistant varieties, cultivation, biological pest controls and botanical controls. The use of synthetic chemical fertilizers and pesticides are prohibited in certified organic production."

The number of organic farmers in NYS continues to increase, driven in part by the increasing demand from consumers for produce that is free of synthetic fertilizers and pesticides. The Cornell Vegetable Program has been working with organic farmers to determine their needs and offer alternatives to conventional production methods.

2017 Cucurbit Downy Mildew Management Guidelines

Last Modified: July 5, 2017
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.

Nitrogen Fertility Options for Organic High Tunnels

Nitrogen Fertility Options for Organic High Tunnels

Several years of foliar sampling in high tunnel tomatoes throughout NYS has shown that organic high tunnel tomatoes generally start out with sufficient or even excess nitrogen, but go into a mid-season dive in foliar nitrogen levels. Given the longer season and higher yields of tunnel tomatoes, a nitrogen fertilizer to inject or side-dress will help prevent mid-season deficiencies.

Frewsburg, NY

This course will demonstrate pest management in fresh market vegetables in both field and greenhouse (high tunnel) vegetables; primarily for those growing for wholesale auction. A hands-on demonstration of weed, insect and disease identification in vegetables including management options such as inter-row cover crops, grafting and where appropriate, spray options will be used to educate growers. CVP Specialists Judson Reid, DarcyTelenko, and Robert Hadad will instruct participants and facilitate peer-based learning. Details on each topic will focus on field observations at the farm.

Announcements

Late Blight Spreading Across WNY Counties

7/19/17 - Late blight (LB) was confirmed in Livingston County on potato this week (the genotype is still being determined). The sample from Erie County from last week was determined to be US-23 which is sensitive to metalaxyl. All of Western NY is at risk for Late Blight infection. Severity values continue build at all stations. The frequent and continuing rainfall has been extremely favorable for the development of LB. Scout fields twice a week. All tomato and potato growers, conventional and organic, should be applying a protectant fungicides and monitoring the DSS to determine spray intervals. Remember to rotate fungicide FRAC groups and use contact fungicides in your program to minimize the chances of fungicides resistance.

If late blight is suspected act immediately! Under favorable environmental conditions late blight develops very rapidly and can spread many miles in a short period. Please take a sample for isolate identification. It is very important to track disease movement. Contact CCE Cornell Vegetable Program Specialists for assistance.

Cucurbit Downy Mildew Confirmed in WNY

Cucurbit downy mildew has been confirmed in Erie County. There have also been confirmed reports from OH, PA and Ontario Canada. If you're planning on spraying cucumbers to control downy mildew, now is the time to do it!

Characteristic disease symptoms are angular, pale green areas bounded by the leaf veins. They will turn yellow and later necrotic. Under high humidity conditions sporulation will occur on the lower leaf surface. Apply targeted fungicides tank-mixed with protectant fungicides weekly and alternated among available modes of action (FRAC code), starting when there is risk for a specific crop based on forecasting program. Refer to the Cornell Vegetable Guidelines for a complete list of products available.

For more information about the disease, watch our new video Better Know a Pest: Downy Mildew or contact Robert Hadad or Darcy Telenko.

Better Know a Pest Video Series

The CCE Cornell Vegetable Program has created 3 new, short videos about common vegetable pests: flea beetlesswede midge, and downy mildew. The videos are part of a series called Better Know a Pest. Watch for more videos as the season progresses.
