I love Endure, but mostly Pyrana! Works better then Endure, and anything I've ever tried. Its expensive, but I buy like four or five huge five-gallons every Tractor Supply and Southern States trip I take. Works best for me!
I've tried a ton of different ones. The best I've found is called Trigger it lasts longer than others- up to 14 days. I've found as long as it hasn't rained it lasts at least 7 days. Around here it's $18 but well worth every penny! Posted via Mobile Device
I LOVE Absorbine Ultrashield. It's the only thing I've found that works for my horses for longer than about 12 hrs. :) They claim it lasts for up to 14 days, but I've found it works for up to 5 days in good weather. It is strong stuff though, so I wouldn't recommend spraying every single day.
