Farming expo to address weed-control issues
Indiana farmers will get tips on ways to control wild plants that are contributing to crop losses of $8 billion a year nationwide during an upcoming farming expo.
Experts say many of the weeds are being brought in from southern states in manure used for fertilizer. The weeds have developed a resistance to some herbicides frequently used to kill them.
The Journal Gazette reports the Tri-State Conservation Farming Expo in Auburn on Friday will discuss options for combating the weeds. Those include crop rotation and using different herbicides the plants aren't resistant to.
Ohio State University professor Mark Loux says mare's tail, giant ragweed, water hemp and Palmer amaranth are some of the most common weeds finding their way into fields in northeastern Indiana.
