Preemergence herbicides can aid in the control of troublesome weeds such as waterhemp and giant ragweed.

When No-Till Farmer (NTF) got its start in 1972, its pages were filled with tips on how to make herbicides like paraquat, atrazine, 2,4-D, Princep and Banvel (an early dicamba formulation) work in no-till systems. In Part 1 of this series, we’ll look at the most important early herbicides for no-tillers. The No-Till History series is made possible by Calmer Corn Heads.
