View Full Version : Crabgrass and late Dimension post emergent

I treated some crabgrass with Dimension .13 percent on fertilizer very late: July 31. It was in the early stages of seed head production. I applied untreated control, regular strength, and double strength.

I was surprised. The crabgrass began to turn brown to a mild degree, after 2 weeks. The double treatment had a more pronounced effect. No effect on control. Stay tuned.

Last year...the late Dimension treatment in the end did not control the crabgrass--slowed it down slightly.
This year it got darker. I was hopeful until I realized it was from the fertilizer in the Dimension which I applied. Iron at high rates seemed to have a mild burning effect on the crab. Turned it black.
