Currently I'm a homeowner that's obsessed with his lawn. However, in my previous career I did landscape maint. , irrigation design, etc. for a fairly large commercial landscape company. I have a tall fescue lawn and paid a local turf company to design a plan I could administer. I'm fully irrigated and follow the fert. rates carefully. I'm trying to address the recurring brown patch problem I'm having. The plan calls for a preventive rate of Compass every 21-28 days starting June 1. However this yr. we were hit with a lot of rain and muggy nights. So, I may have let a small outbreak begin. I used the higher rate June 1 (I believe .2 or .25/ 1,000) Compass 18 days later (it rained on days 13, 14, 15, 16) with Banner Maxx at a moderate rate. I realize the infected turf may not recover and it's cheaper to buy seed in the fall. However, want great turf and will spend the time/money to get it right. My question(s) are: 1. I'm alternating with Banner Maxx to prevent resistance to the Compass. Is this the best idea, or should I use something like Heritage to alt. Although it may have the same mode. 2. If Heritage is better, can I buy the Ag.. version (Abound) and save money? Remember, I'm not spraying anywhere other than my lawn. I found Abound at $235/ gal. and each gal. has 2.08 pounds of active ingredient. Heritage is something like $400 per pound and has only .5 pounds of active ingredient. I enough Compass for 2 or 3 more applications, but other than starting earlier in the yr. , what's my best plan. thanks, and sorry for the long post. I didn't want to ask question without giving enough info.
