I got this little note with a renewal form and prepayment check. "Paul- I would like you to use "Bayer Grub-Ex" for the grub control. One application is supposed to last all summer. It's available at Bomgard's in Columbus 24.95 for bag that covers 5000 Square feet xxx" This customer hasn't wanted grub control until late last summer when he thought he was seeing some problems. I think the prob was more from lack of watter but he asked for a treatment then even though I told him it wouldn't be very effective that late in the season. I have no problem with doing grub control this season at the right time but I usually use Mach II with fert from Lesco and have good results. plus a 14000 sq ft bag is about the same price as his 5000 sqft bag. do I just tell him that I use what I want, or do I try to explain to him why I use what I do and hope he accepts that, (he might, he's pretty reasonable most of the time) or do I just go buy the homeowner stuff he wants and say nothing. One other thing is that this costumer lives out of town and this is just a cabin on a small lake.
