Annual UW Extension publication detailing best practices for commercial vegetable production in Wisconsin, including approved insecticides and fungicides for pest management.
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.
Cucurbit downy mildew is a destructive disease of all plants in the gourd family, including cucumber, watermelon, cantaloupe, pumpkin, and squash. This fact sheet covers the disease's life cycle and symptoms and offers effective means of control.

Application timing of reduced-risk (RR) modes of action (MoA) for the control of CPB.
For most CPB chemical management tools, timing application occurs with the appearance of first instar larvae in the field. Early instar larvae are the most susceptible life stage for chemical management, and applications should be timed with the midpoint of egg hatch. The first application should be followed up in 7-10 days later with a second application of the same compound depending on the formulation and label restrictions. Refer to the UW-Extension publication Commercial Vegetable Production in Wisconsin (A3422) for a list of registered insecticides and management recommendations.
Applications of ledprona (Calantha), novaluron (Rimon), tolfenpyrad (Torac), spinetoram (Radiant, Delegate), or abamectin (Agri-Mek) should be applied when nearly 50-75% of egg masses have hatched, and a few 2nd instar larvae are present from the earliest hatched egg masses. These 1st generation larvicides often require 2-3 subsequent re-applications spaced on a 7-10 day interval to achieve sufficient control.
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.
