Thanks to all who have replied to my past post. You all have been very helpfull! Details of lawn. Zone 10 Palm Bay, Fl 8 year old lawn Atrizine application every spring ( when it was available) Image applications for spot treatment in the summer for onion, nutsedge etc. MY problem Crepping Beggarweed!!!!!!!!! I cannot kill this crap. Heres my houes from the curb. 85% of the yard looks good A close up of the good stuff The bad stuff.... Beggarweed!!!!! I would say 15% of my yard has patches of this stuff. I have treated with Image herbicide which turns the weed yellow but seems to come back stronger! I have mannually pulled large patches but the roots just break off, the root system runs under and between the St. Augustine grass roots. I applied a second spot treatment to the worst areas of the lawn and this is what itr looks like. It damaged the lawn far worse that the weed. (im glad I did a spot treatment!!" What will kill this stuff?!?!?!?
