back in May I lost almost a whole yard full of the best looking fescue on my block. I thought it was drought stress but later found out it was BROWN PATCH FUNGUS. left untreated it spread and killed 85% of my lawn... oh well.. lessons learned... back to the drawing board.... i just did a core aeration/overseeding ( lesco transition blend ) yesterday and I'll know about the BROWN PATCH FUNGUS next year and get my fungicides out EARLY around April/May and treat every 30 days or so.. At my local Lowes they're having a CLEARENCE SALE on MAXIDE DUAL ACTION LAWN DISEASE KILLER! 10 LB bags - treat 5000 squ.feet for only $4.25 a bag!!! regular price $18.00. Active ingrediant = Azoxystrobin 0.31% ( the same stuff that is in the way more expensive product Heritage ) I picked up 6 bags thinking I'll be able to treat my lawn ( about 5000 sq.ft ) once a month April,May,June, July,Aug 2011 ...but my question is WOULD I BE ABLE TO USE THE SAME FUNGICIDE EACH MONTH OR SHOULD I SWITCH UP BRANDS THAT CONTAIN DIFFERENT ACTIVE INGREDIANTS? I just couldn't resist that clearance price! what do you think?
