I use the blue dye marking agent for spot treatments;this is the best way to control your application and coverage. I used it with Quinclorac as a post emerge spot treatment for crabgrass and Triclopyr 4E for spot treatment on brush, poison ivy, and thistles.

Best products and service, as always!

very slow working many applications were needed

Keystone was great to work with-fast shipping and very helpful, was trying to save money but should have spent the money and gotten roundup.We even X4 the mix ratio very slow kill and some not at all. I am giving 3 stars -5 stars for the service and 0 stars for the product

Kocide 3000 performs as well or better than other soluble copper fungicides that I have used. Kocide 3000 remains in solution with little agitation. Like other wettable powders Kocide 3000 needs to be pre-mixed in a concentrate. I find that using a Spreader-Sticker is a must but that goes without stating.

Pinene II works well as a Sticker Extender but is not as effective as most surfactants I have used. Mixing should be started in a wetted smaller container before diluting into the spray batch Pinene II adheres to un-wetted surfaces and leaves a residual film. Pinene II mixes well after agitation and so far has proved to perform well as a Stick-Extender but tends to bead up on crop leaves. Pinene II works well as a Sticker Extender but is not as effective as most surfactants I have used. Pinene II has a low concentration ratio thus, it is about as ecinomical to use as a Surfactant.
