There are many online tools available to growers to aid in decision-making when it comes to weather-based risks. See our curated list of tools we have developed or recommend.

Documents

title page of the guide

This guide offers the latest recommendations for disease, insect, and weed management in Wisconsin’s most common commercial vegetable crops. Also included are lime and fertilizer recommendations as well as insect identification information and keys.

Crops covered include asparagus, bean, carrot, celery, cole crops, cucumber, eggplant, hops, horseradish, leafy greens, melon, mint, onion, pea, pepper, potato, pumpkin & squash, sweet corn, table beet, and tomato.

This document contains a list of fungicides registered for control of potato late blight in Wisconsin. In-furrow and seed treatment registrations are omitted. Not a comprehensive list. Most fungicides listed are for use in conventional systems. Where generic fungicide trade names are listed, there may be numerous.

Instructional Videos

Instructional videos that can be used as a primer to learn about the basics of potato production, initially focusing on Integrated Pest Management (IPM) basics. Key aspects of insect, disease, and weed IPM programs are highlighted.

In under 20 minutes, Ari Abbrescia, Organic & Sustainable Agriculture Outreach Specialist with UW-Madison Extension provides an informative tutorial on why and how the insect and disease models work to improve our understanding of when pest and pathogens may be active and managed for to proactively prevent vegetable crop damage.

Seed Certification

Healthy seed potatoes are the key to success for potato growers and seed potato certification helps growers raise a profitable crop. Since 1913, the Wisconsin Seed Potato Certification Program (WSPCP) has inspected and certified Wisconsin seed potatoes.

Grower Education Conference

Proceedings of the WPVGA and UW Division of Extension Grower Education Conference can be browsed online at https://wpvga.conferencespot.org/. This conference takes place the first week of February each year and brings together growers, researchers, and industry representatives from across the Midwest. Event details will be listed in the Events page of this website. More information is also available from the WPVGA website.

Major Projects

Potato Soil Health Project: The Potato Soil Health Project was established to identify reliable indicators of soil health and effective methods for increasing soil health in potato cropping systems, to learn what determines whether growers adopt good soil health management practices, and, ultimately, to improve soil health in potato cropping systems across the United States.

Management of Potato Tuber Necrotic Viruses: This 5-year NIFA-funded collaborative research program was designed to improve diagnostic methods and management strategies for viruses of concern for potato production including Potato virus Y (PVY), Potato mop-top virus (PMTV), and Tobacco rattle virus (TRV). Now concluded, many resources have been posted on this website for future reference.

Potato Virus Initiative: Information and resources related to management of PVY and potato breeding programs aimed at developing PVY resistant lines.

Diploid Potato 2.0: To address potato breeding constraints, our long-term goal is to convert potato into a diploid (2x) inbred-hybrid crop. New germplasm resources, coupled with improved methodologies in genomics and quantitative genetics, will allow us to reconstruct potato as a 2x crop amenable to breeding strategies analogous to those used to produce elite maize F1 hybrids. This change will accelerate breeding timelines, dramatically increasing the rate of cultivar improvement and the ability of potato breeders to meet the needs of consumers and the industry.

Wisconsin Clean Hops Program: The Wisconsin Clean Hops Program at the University of Wisconsin-Madison maintains a collection of pathogen-free hop varieties as a resource for hop growers and gardeners. Stock plants are maintained in greenhouse facilities on the UW-Madison campus, and are tested for pathogens on an annual basis.
