I sprayed some johnson grass back in the first of May and now my fescue/bluegrass lawn is dead or suppressed in those spots. Has anyone had these same problems and come up with a cure besides reseeding? Will iron help bring out the suppressed areas. Also on the Fusilade label it doesn't have a temp. rating or restrictions. Has anyone noticed this. The days I sprayed it was in the 70's but several days later we had spikes in temps to 80-90. This is why my lawn is stressed or dead in those areas. What has been some of your guys results with Fusilade II on cool-season turf to treat Johnsongrass, dallisgrass, crabgrass, foxtail and etc. What rate do you use. I mixed at the recommended rate for spot spraying and it worked great except for the stressed and dead spots.
