Soil-active Residual Herbicides: Preventing Early Emergence

1. Soil-active Residual Herbicides: Soil-active Residual Herbicides: Preventing Early Emergence Preventing Early Emergence A pre-plant soil-active residual herbicide application is made for the purpose of controlling weed seeds and weed seedlings before they become a problem. Some advantages of a soil-active residual herbicide application are: Reduction of weed seed banks: Soil active residual herbicides target weeds as they germinate and before they have a chance to set seed, thus helping reduce the overall weed seed bank in the field. 1 Extended protection: 2 In a season when conditions delay the application of pre-seed or in-crop herbicides, residual herbicides can offer protection and help keep populations in a susceptible stage until the next herbicide application. Increased herbicide diversity: 3 Soil active herbicides typically allow growers to incorporate different modes of action at a new or different application time. This is another way to throw weed populations off their game that may have adapted their growth cycle. Fierce EZ herbicide is an excellent soil active herbicide which offers residual control of both broadleaf and grass weeds. It features two modes of action, Group 14 and 15, and uses active ingredients that aren’t typically used for in-crop applications. Herbicide resistance has been presented as a complex issue and an increasing problem. While we can’t stop weeds from developing resistance we can slow down the development by rotating herbicide groups through soil active, pre-seed burndown and in-crop herbicide applications.
