CPN June 2021 Newsletter

Jun 11, 2021

Welcome back!

We are pleased to send out our second newsletter for the Crop Protection Network (CPN). We want to highlight some of the critical issues affecting field crops to our audiences. We have a lot of passionate individuals involved, and we’re excited to let you know about protecting crops and keep you up to date on the best methods!

Virtual Crop Scouting School

The 2021 Virtual Crop Scout School is underway, and we’ve put together 22 free webinars from Midwest crop specialists at major universities. Topics are set up in segments, allowing for ease of access depending on your schedule. Crop scouting is an essential step in integrated pest management (IPM) that can result in higher profits and yields.

“The Virtual Crop Scout School is coming on the heels of a web book on crop scouting released by CPN earlier this year,” said Daren Mueller, Extension associate professor at Iowa State University.

Funding for this programming is provided by the USDA National Institute of Food and Agriculture, Crop Protection Program and Pest Management Program through the North Central IPM Center.


CPN has unveiled a new e-book, Fungicide Use in Field Crops, with information on the importance of optimizing fungicide applications, as well as how to reduce environmental concerns and fungicide resistance risk associated with fungicides. The web book aims to provide a survey of fungicide knowledge and the best practices for effective crop management. Updated Fungicide Efficacy Guides are also available for corn, soybean and wheat.

Soybean Cyst Nematode Resource now available

Soybean cyst nematode (SCN; Heterodera glycines) causes approximately 1 billion dollars in soybean revenue losses each year. Sampling and checking for signs and symptoms are some of the best ways to identify nematode presence in the field. The cropping season presents the best time for detection, as microscopic tools are usually not necessary to locate SCN females on roots. More information on SCN management can be found on the Crop Protection Network website.

Severity Training Tool: Leaf Disease and Insect Defoliation

Accurate assessment of disease severity or insect injury is useful for determining pesticide efficacy in research trials or to help make in-season management decisions. Field crop scouts and researchers can overestimate the severity of disease or insect injury on plant leaves. The CPN developed the Disease Severity and Defoliation Training Tool to help improve accuracy when examining these issues in the field. Training is available for corn leaves and ear rots, and soybean leaves.

CPN Trivia

Congrats to Bethany Kroeze for guessing April’s trivia question! The answer—white mold!

This month’s question: Soybean cyst nematode (SCN) has been detected in how many US states as of 2020?

Send us your answer to cropprotectionnetwork@gmail.com by June 20, and you will be put in a drawing for a Crop Protection Network t-shirt. The winner’s name will be announced in the next newsletter.
