This product works very well to control difficult to control weeds, both pre and post emergent. However, it can be extremely toxic to desirable plants. Product is quite persistent and if moved near desirable plants by water or dust, it will severely effect them. I have seen damage to grapes over 100 ft. from application site. TVC was applied while grapes were dormant, but apparently carried by dust to remote vines. Vines 10 ft from application were either killed or severely stunted. My guess is that materials needs to be better incorporated deeper into soil where wind erosion sould be less of a problem.
worked after one spraying in some areas. (ditch bank, around shed and a/c unit) ground still dead no sign of weed growth for 4 months now. had to apply second spraying on the parking lot area within a month to kill new growth. weeds are now starting to come back in parking area. the parking area gets only afternoon sun , don't know if this may be reason for weed comeback or not, but better than monthly spraying of round-up.
Product is described just as ordered, only issue was first order was not delivered due to damaged shipping container, I received an open and empty box from USPS, products that contain liquids should be packaged and sealed as to not allow outside sources to open and access the package contents. Aside from the shipping mishap "Do My Own" was very prompt in replacing the product, shipped and received within 3 days. Great service!!!!!!!
dont know if it will work for 1 yr but it did kill stuff. of course I added some gordens big and tough killer to it and it killed everything it touched. kind of pricey but if it woks for a year it will certainly be worth it.
TVC is very effective. It works well with hard-to-kill weeds like morning glory, bindweed, and whiteweed(nightshade). lf broadcast, TVC will sterilize the ground and prevent more weeds for 6 months or more. Also, can be mixed with glyphosate. It is fairly expensive, though.
