Will Pin Dee 3.3 T&O Herbicide damage existing plants if they are sprayed?

I plan to spray very close to and may actually spray desert landscape plants such as cactus, agave, ocotillo and others

Answer:

Pin Dee 3.3 T& O Herbicide is for the use of pre-emergence control of most annual grasses and broadleaf weeds as they germinate and does not injure anything growing in general.  According to the product label, cactus, agave and ocotillo are not included on the on the list of established plants that have been tested as safe for this product to be applied around and over the top of.  We would recommend avoiding any contact with desirable plants just to be safe.
