Worked for me wrote

Best to use when a little shady. Can't see very well in bright sunlight. Rinses of skin and clothing easily (didn't turn my laundry blue).

Great for knowing where you have sprayed wrote

Glad AM Leonard is carrying this - and seems to be safe with Roundup, some marker dyes seem to neutralize Roundup, similar products. The Turf Mark dye is great for knowing where you have sprayed especially when doing spot weed control with a drift cup. And how much product you have applied - a touch for sensitive weeds, more of a soaking for tough weeds. The blue color fades after a couple of days so aren't painting your yard blue. The mix rate is 1 oz per gallon for hand sprayers but I found that after the initial 1 oz/gal I now use 1/2 oz/gal. I also pour right from the bottle into a measuring cup with product. The squeeze to measure bottle is a nice idea but I was always getting dye spilling. Unlike heavier 2 cycle engine oil.
