The new 2016 Herbicide Guide for Iowa Corn and Soybean Production publication provides information on product and management updates, the role of preemergence herbicides in glyphosate resistant crops, corn and soybean herbicide effectiveness ratings, and herbicide package mixes.
The publication contains four tables on herbicide sites of action, and information about typical injury symptoms. It also lists the effectiveness of different herbicides for controlling grass, broadleaf, and perennial weeds in corn and soybeans; grazing and haying restrictions for herbicides used in grass pastures; and the active ingredients in herbicide prepackage mixes.
It is now available online at the Extension Store.
