When using Kerb ® SC specialty herbicide, treated areas must receive ¼ to ½ inch irrigation immediately following product application. IPM Statement: Poa annua has evolved resistance to every effective mode of action that has been widely used to control this weed. To limit the spread of resistant Poa, there must be a rotation of products with differing modes of action, or applications of combination treatments with 2 or more modes of action. For further resistance management techniques and guidelines, please refer to Kerb SC specialty herbicide label. Higher amounts of rainfall and/or higher than average temperatures might make it necessary for higher rates or a repeat application to achieve adequate control. Lack of control the previous year/season due to potential resistance should be met with university plant testing or earlier application timing. It is important to contact your local Corteva territory manager to determine the best choice for poa control. A preemergent herbicide application for control of crabgrass and other spring/summer weeds must be applied after February 1, 2027, and prior to March 15, 2027, or prior to target weed germination.
*Guarantee is subject to meeting program requirements.
