I have found some Trimec PLUS for sale. I am in need of killing off grassy weeds and have read mixed reviews on Q4 and some others. Some saying it takes multiple treatments and others sayingit's not worth the money. I know for a fact the Trimec plus is a killer since it has MSMA. Only downside is it huting or frying desirables in temps over 90. This week around here not supposed to be above mid 80's. Would you go ahead and buy and spray this if you were me?
