The Cornell Guides for crop management of various commodities are important resources that outline crop, soil, nutrient and pest management and pesticide recommendations based on NYS regulations. Annual updates to these resources are critical to maintain accuracy and provide the best guidelines for NY farmers. The NYS IPM staff have played integral roles in composing and updating sections of these guides for years. In 2019, the Cornell Guide for Integrated Crop Management was in need of significant updates to the plant disease and weed management sections, and the insect pest sections to a lesser degree. We completely overhauled all fungicide efficacy tables to reflect currently available products, and made updates to the text to reflect current pests and management options for each commodity. We worked with the field crops entomologist and PMEP to update insecticide tables and text, and added a new table of available insecticides for managing pests of stored grain. We also suggested appropriately qualified CCE staff to completely overhaul the weed management sections for each commodity, which had not been updated in many years. The 2020 version has been modernized and is currently available for purchase.
