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.

Fall Pest Management for Diversified Vegetable Farms

Fall Pest Management for Diversified Vegetable Farms

Do you want to get a head start on managing next year’s insect pests? Focus on managing your crop residue. Removing or tilling in crop residue this fall could make a big impact towards pest management. Read for pest-specific strategies on residue management as well as other cultural control options.

Consider pests when planning your vegetable rotations

Consider pests when planning your vegetable rotations

Wisconsin is one of the top states for commercial vegetable production.  With the diversity of crops available in a vegetable rotation, the puzzle pieces of locating each crop within the farm can be difficult to fit together each year. One of the factors to consider when planning your crop year is preventing pest problems.
