Waterhemp Management in Missouri
Metadata[+] Show full item record
The pigweed, or Amaranthus, family of weeds is one of the most common groups of weeds in field crops across the Midwest. These weeds can cause significant crop yield losses, interfere with harvest, and some species have shown an ability to develop resistance or tolerance to herbicides. In northern and central Missouri, waterhemp has become the predominant species of pigweed. This publication provides guidelines for waterhemp management in Missouri.
