Carrots are a slow growing crop which means they are highly susceptible to weed competition. The use of herbicides to eradicate weed competition is critical to maximizing yields. The Bayer herbicide, Sencor, is a highly effective post emergence product for providing knockdown and residual weed control in carrot crops.
