PEAQ Forages Monitor

Predictive Equations for Alfalfa Quality (PEAQ) Stick monitoring is conducted by the UW-Madison Division of Extension Crops & Soils and Dairy Educators of Grant, Green, Iowa, and Lafayette counties. 

PEAQ is a method developed by the University of Wisconsin to provide an estimate of the relative feed value of first cutting alfalfa based on crop height and maturity.  Our goal is that this information will help forage producers and agronomy professionals track the growth and development of alfalfa in their area so they know when to check their own fields to target their preferred quality while maximizing tonnage.

Samples from participating farms will be collected on Mondays and Thursdays with results posted online Tuesdays and Fridays during the month of May.

For more information, contact Jordyn Sattler, Crops and Soils Educator at jordyn.sattler@wisc.edu or the Green County Extension Office at 608-328-9440.

Managing Alfalfa Insect Regional Survey

Alfalfa weevil has become a significant spring pest for alfalfa growers across the Midwest in recent years. Alfalfa weevil feeding on leaves can reduce hay yield and quality, leading to economic losses. There have been reports of a resurgence in alfalfa weevil populations across the Midwest, with damage being more severe and widespread than in previous years.

If you are an alfalfa grower in Wisconsin, we want to hear about your experiences managing alfalfa weevil and what adaptations are needed as the dynamics of this pest change.
