This year I've picked up quite a bit of pre-emergent business for homeowners' garden and shrub areas. I've been using Treflan 5G granular so far. I don't really like the granular because I have to use my shoulder harness broadcast spreader to get the accuracy and even then, quite a bit overflows into the turf. No big deal but a waste of product. What I'm wondering is how a Lesco tank sprayer with liquid Pendimethalin or something similar would work? It seems once the initial cost is over, I'd save money, get better and more even coverage, and might even get better results. This is a fairly new thing I've been working at this year and although it's growing, I've got plenty to learn. Ya'll tell me what I'm missing if anything. Also, would liquid Pendimethalin turn brown-dyed mulch yellow? Wouldn't a homeowner be impressed with that?
