Vegetable Pest & Disease Forecasting with the VDIFN Tool: User Tutorial

Vegetable Pest & Disease Forecasting with the VDIFN Tool: User Tutorial

Managing vegetable pests and diseases can be a challenge, especially when patterns and outbreaks vary from year to year. The Vegetable Disease and Insect Forecasting Network (VDIFN) helps take the guesswork out of management by providing data-driven risk forecasts for your farm. This guide walks you through key concepts behind pest and disease models, VDIFN basics and navigation, step‑by‑step examples for insect pest and disease forecasting, and resources for integrated pest and disease management.

Living Aisles Case Study #1: Sawyer Farm, Worthington, MA & Momentum Ag

Living Aisles Case Study #1: Sawyer Farm, Worthington, MA & Momentum Ag

Most farmers are familiar with the benefits of cover crops: they reduce erosion, improve soil health, and help suppress weeds. Cover crops are often incorporated into fields as part of crop rotations, but they can also be planted in the aisles between cash crop beds, providing cover during a time of year when the soil is typically bare. These “living aisles” add additional advantages, such as reducing mud during rainy periods, allowing farmers to access beds when the ground is wet, and keeping harvest bins cleaner. Depending on the species used, living aisles may also be allowed to grow into beds after harvest to provide winter cover.
