Corn Diseases in Southwest NY
Joshua Putman, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program
The 2019 growing season was favorable to diseases in our corn and soybean production systems. In southwest NY, Northern Corn Leaf Blight (NCLB) and Grey Leaf Spot (GLS) showed up and spread throughout our corn fields. Northern corn leaf blight fungus survives the winter on infected corn residue and remains on the soil surface. As temperatures increase in the spring, the fungus produces spores which then splash or are wind-blown onto the lower canopy of the corn plants. Last year, the cool, wet summer allowed for early appearance in our corn fields. Grey leaf spot is a destructive disease that can significantly reduce yields. Just like NCLB, the disease survives on corn residue on the soil surface and splash from the soil surface onto the lower leaves of a corn plant. The wind can carry the spores to a neighboring field if the disease is present in the crop residue. These two diseases can result in 10-50% yield reductions if the timing and conditions are favorable. Weather is the primary influence on the development of these diseases, but proper management with hybrid selection and use of an in-season fungicide will help limit the exposure to these diseases. Contact your local extension specialist for correct identification and management of these pests!

Hazard Analysis Critical Control Point (HACCP) Training Program for Meat & Poultry Processing
April 17 - April 18, 2024
Ithaca, NY
The Cornell Agricultural Marketing Research Program (CAMRP) will offer a Hazard Analysis Critical Control Point (HACCP) Training Program for Meat and Poultry Processors at the Cornell University campus in Ithaca, NY. The course is taught by Penn State University instructors Martin Bucknavage, Senior Extension Program Specialist, and Jonathan Campbell, Associate Professor and Extension Meat Specialist. The training course covers the fundamentals of HACCP for meat and poultry processing operations. It provides participants with hands-on experience in developing a HACCP plan.
The course is recommended for plant management, HACCP coordinators, quality assurance/control personnel, sanitation management, line supervisors, and line operators employed by meat and poultry processing plants. The course is certified by the International HACCP Alliance and meets USDA requirements for HACCP training.
Cover Crop Breeding Field Walk
April 23, 2024
Freeville, NY
You're invited to join us for a Cover Crop Breeding Field Walk!
The Cover Crop Breeding Network breeds fall-sown cover crops for traits like fall emergence, winter survival, spring vigor, high biomass, hard seed, and non-shattering pods
Join us to walk the trial fields, talk about what we're seeing (and not seeing), hear about past years' results, and learn about CCB lines approaching commercialization.
Advanced line trials - Crimson clover, hairy vetch, winter pea, and winter canola
Planting date trials - Cereal rye and winter pea
Breeding nurseries - Cereal rye and winter pea (across the road & optional!)
