For those who have used Trico Pro,  the sheep fat material, to repel deer.  What rate did you use per acre and in how much water?   A sales rep is telling me a quart to the acre in 20 gal of water.  The label is telling me 1.65 gal/acre in 80 to 120 gal of water.  This stuff is $85/2.5 gal in my area, so this will decide whether I try it or stick to the old 308.
