Last Saturday morning while the dew was still on the leaves, I put some sendero in the backpack sprayer and hit the mesquite and huisache on my place. Most of them were smaller bushes less than 4 ft tall. I went back yesterday(Friday) and found that everything I sprayed was brown. Time will tell if they come back, but so far it is looking pretty good. I used 7 ounces sendero, 2 ounces surfacant, and two gallons of water. Sprayed to moisten the leaves, but not enough to drip. Next time I'm definitely using some dye so my dumbass doesn't miss so many.
