The potential for herbicide carryover varies widely based on the product used, when and where it was applied, and what the weather has been like since the time of application. Herbicide soil persistence or residual life is the length of time a herbicide remains active in a soil. Residual activity: An herbicide is described as having low residual activity if it is neutralized within a short time of application (within a few weeks or months) – typically this is due to rainfall, or by reactions in the soil. Long-lasting residual herbicides like this normally don’t have the burndown activity that these products do. If rain does not occur within 21 days, sprinkle irrigate with 0.5 to 2 inches of water.
