Spraying The Mesquite

We spent several hours spraying the mesquite trees this weekend.  It is a pest we are slowly trying to eliminate or at least manage.  The biggest problem that directly affects us are the giant thorns which can penetrate tires and my hiking boots.  Some thorns are 2 inches long and extremely sharp (see pictures of thorns in previous postings).  Even a small tree has big thorns.

This is our first year spraying.  The fellow who leases our land has done it previously.  Most of the large trees have been killed and we are now going after the smaller ones.  Cows and birds eat the seeds because they are very sweet.  The seeds are then redeposited resulting in new trees.

We sprayed these trees yesterday.   They look like they're dying...  The red you see is spray paint we used to mark those trees we've sprayed.  It is a step we dropped today as we were a little more organized.
