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.

September 26 - September 27, 2017
9:30 AM - 4:00 PM
Salamanca, NY

This event has been cancelled due to low registration numbers. Farm food safety is common-sense practices organized to assist farmers to improve their skill set to continue to grow safe and healthy food.

Day One of this training will be an educational training on farm food safety principles and practices to provide the background and information for farmers to understand how to minimize the risk of food born disease contamination. Day Two will be for those who want help with writing a farm food safety plan.

Season Extension - Stretching Tomato Season and Winter Greens

October 4, 2017
4:00 PM - 7:00 PM
Allegany, NY

What do you need to do to stretch out your high tunnel tomato season or establish a profitable crop of winter greens? Meeting the full season's nutritional demands of tomatoes under organic management is challenging. Juggling diverse succession crops and keeping the tunnel profitable year round adds an extra level of difficulty.
