Organic

CVP Organic

According 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.

Grafting Tomatoes Video: The Motivation and Benefits of Grafting

As soil based production of tomatoes continues in tunnels and greenhouses, risk of root-zone diseases, insects and nutrient imbalances increase. Grafting, the combination of two separate cultivars into one plant, is one management approach to these challenges. Learn more about the motivations and benefits of grafting tomatoes in this video of Judson Reid, Extension Vegetable Specialist for the Cornell Vegetable Program.

How Copper Sprays Work and Avoiding Phytotoxicity

Copper has been widely used in both conventional and organic production for some time. Copper was one of the first elements used as a plant fungicide (the other was Sulfur). Its discovery can be traced back to the famous origin of Bordeaux mixture, containing a mixture of copper sulfate (CuSO4) and slaked lime, and used for downy mildew control in French vineyards.

Leek Moth Control and Information

Leek Moth Control and Information

Leek Moth was detected in four home gardens in Plattsburg, NY in 2009. It was first detected in Ontario, Canada in 1997 where it has become problematic especially to small-scale, organic growers in eastern Ontario and to commercial producers in western Quebec, who have limited insecticides available to them.

Leek Moth continues its spread to more farms and gardens across the U.S., a new comprehensive website is available to aid in the identification and management of this pest. This Cornell website features maps of the distribution of leek moth, protocols on insect monitoring and identification, best management practices for farms and home gardens, a photo gallery of damage symptoms and a comprehensive resource section.

Resource Guide for Organic Insect and Disease Management

Organic farmers rely primarily on preventive, cultural and integrated methods of pest and disease management. However, there are a number of materials available for use that can complement and support organic management. This guide was developed to provide a useful and scientifically accurate reference for organic farmers and agricultural professionals searching for information on best practices, available materials and perhaps most importantly, the efficacy of materials that are permitted for use in organic systems.

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.
