It is a very new spray, I will be trying it this coming year. Spray Rep told me that it is like crossbow except it kills a broader range of broadleaf and has a residual effect of roughly three months (two months in the real world). If it is anything like crossbow we will be using 100's of gallons this coming year. That is the only thing I didn't like about crossbow it didn't have much residual at all. Milestone is supposed to be like crossbow in regard to, abeing able to put animals directly in the field. Just my thoughs for what little they are worth. Russ
