Just wanted some ideas on what you guys do, or use for big yards. We have quite a few yards that we do that are 1-6 acres with a pro-lawn shielded sprayer on a woods (grasshopper) ztr mower. The majority of the yards don't have water sprinklers, so we try to time pre-emergent apps. when rain is forcasted within 24-48 hrs. I also put down merrit 75 with some of them for grub control. I usually use pendulum 3.3 for pre-emergent because it works well for sandburs (stickers), but it supposedly degrades quickly with UV light. We are doing 2nd apps. now and not any rain forcasted for the week. Should we try another pre-emergent or just explain to them like we always do that if it doesn't get watered in then expect problems with stickers and grubs. We generally have success with this combo, but weather sometimes doesn't cooperate.
