Fungicide Information for 2021 – Vegetable Crops Hotline

Fungicide Information for 2021

As vegetable growers get ready for the 2021 season, one question might be to find up-to-date information about fungicides and how to apply them. Some possible resources are listed below.

  • The Midwest Vegetable Production Guide for Commercial Growers offers recommendations for fungicides and other pesticides and practices that have been updated for the 2021 season. The guide, which is searchable online, can be accessed at mwveguide.org. Although official hard copies of the guide are not being sold through Purdue University this year, if you have questions about how to get a hard copy of the guide contact Dan Egel.
  • Fungicide schedules for cucurbit growers can be found at the links below. This information has been updated for the 2021 season. Melon and watermelon information can be found here. Pumpkin information can be found here.  If you have trouble accessing these sites or you would like a hard copy, contact Dan Egel.
  • Purdue has a weather-based disease-forecasting system, known as MELCAST, developed by Rick Latin and run by Dan Egel. MELCAST lets growers schedule fungicide applications for cucurbits based on the weather. A table of what areas of Indiana are covered by MELCAST is located at info. An extension bulletin about how to use MELCAST can be found here. A record sheet to keep track of MELCAST information can be found here. If you need hard copies of any of this information, contact Dan Egel.
  • A presentation given by Anthony Keinath of Clemson University at 2021 Southwest Indiana Melon and Vegetable Growers Spring Meeting describes fungicides used to manage gummy stem blight and anthracnose of watermelon.
