Advice on Pistol weed killer

Phil, here's the description from product sheet, note comment about no, little lateral creep. We've not noticed any problems, but as mentioned we do take additional steps when we spray.

Hope that helps.

Mode of Action
The 2 active ingredients in PISTOL® herbicide have complementary modes of action. Diflufenican (DFF) is extremely hydrophobic:

Once applied, it adheres to the surface and forms a skin or ‘barrier’ that prevents germination.
Because it’s hydrophobic, it stays in place preventing weed germination.

Glyphosate is a translocated contact herbicide, which is taken up through the foliage, and translocated throughout the whole plant. It has post-emergence activity only, killing seedlings and established weeds.
The two components have a synergistic effect in this formulation, the diflufenican giving the glyphosate faster activity for the initial kill of the weeds.

Tree Safety
The product is completely safe to all mature street trees. It remains near the surface of the soil, and there is little or no lateral movement. The product does not, therefore, come into contact with the trees’ roots

I'd give them a wide berth.... at least a couple of feet........ I found even the faintest drift of the herbicide onto the foliage of adjacent shrubs/roses was enough to make them look very poorly!

Have you got a hood for the sprayer to contain the drift....pistol is perfect.

We have this at a site.

Obviously pick your weather conditons carefully, then:

Simple solution - we bought half a dozen sheets of Cordex (what builders use to protect floors in commercial buildings) and lay along edge so we can spray over. Can then be taken somewhere on site/gravel, washed down and reused.

Thanks guys, I'm more concerned whether you get much lateral 'creep' from the residual part of the weedkiller, rather than coshing the poor old Hebes over the head with glyphosate!

The only damage from pistol 'creep' ( a great name for a rock band ) I found was onto a grass slope adjacent to the gravel path otherwise no problem to plants within 6ins of the path.

Thanks everyone, much appreciated.
