Description

Many fanners are reevaluating their weed management practices to see if their use of herbicides can be modified. Since 1989, we have done work on reduced herbicide rates in com. A total of 11 trials with preemergence herbicides and one with preplant incorporated products have been done. A trial in soybeans with preemergence and postemergence products was done in 1991. We achieved a reduced use of chemicals by either lowering the rate of a broadcast, preemergence or postemergence spray or by applying a preemergence herbicide in bands over the crop row.
