I am going to try out Dimension ultra 40WP on a larger property tomorrow. This property is only partially treated and is loaded with crabgrass . My thinking is, use Dimension and see how results are with split apps. on young crabgrass on my second split application. South program two and three are my question. What program are use using in Oklahoma? Program 2 is 2 pouches per acre, or .25#ai per acre. And program 3 is 2.5 pouches per acre or .31#ai per acre. This would be a split application with the same amount on the next application. The owner waits until the crabgrass seeds out to mow and moves the seed all over the property.
