Marengo is One of the Least Expensive Program Options for Weed Management
One cost-effective way to reduce labor expense is the use of preemergence herbicides. When evaluating different preemergence solutions, it is important to look at the total program cost, which is best measured as cost per acre per month of control. This includes:
- cost of product and labor for the initial application
- cost of product and labor for clean-up
- cost of product and labor for any reapplication treatments.
Products that are less expensive up front, but have a short residual will require more frequent reapplication and/or more clean-up between applications. This drives both labor and product costs. Products offering longer residual control will reduce the frequency for reapplication and clean-up applications because they last longer, reducing labor and product cost. No product lasts longer than Marengo, making it one of the least expensive program options for weed management based on cost per month per acre of control.
A product that lasts up to 4 months will have to be applied twice to achieve similar results to a product that lasts up to 8 months. That means the labor cost will be twice as expensive for the shorter-lived product. Every herbicide application includes labor for:
- site preparation
- application prep (equipment, handling, mixing, etc.)
- clean up (equipment, disposal, etc.)
