I met with the bayer rep few weeks ago and he gave me some rates I should use for fall pre. I was researching the label and the rates seem a tad high. Has anyone used this product last year and what rates did you go at? whether u used full or split? I know one company around me that used it and yards looked good but cant seem to find out what rate he used. I wanna stay clean but I don't wanna throw money away either. Any ideas?
