The mixing rate of Defendor Herbicide is 0.09 fl oz per gallon of water. This will cover 1000 square feet.
Defendor Herbicide is not labeled for use around edible plants such as a vegetable garden. There are very few residual herbicides that have such labeling. Defendor is just a post-emergent herbicide, so it would not persist in the soil for very long, however, it should not be sprayed in a way where it would contact desirable plants. Please see the product label for complete restrictions and precautions. We do sell Avenger Herbicide which is an organic post-emergent herbicide that would not affect future plants. Avenger herbicide will kill any plants that you spray, so you would need to be careful to avoid spraying desirable plants. We do sell Monterey Vegetable and Ornamental Weeder which is a pre-emergent herbicide that can be used around certain vegetables. See the product label for complete application instructions.
As long as you keep pets/children out of the area while you treat and until Defendor Herbicide application has had time to completely dry it is safe for pets and people to return and resume normal activity
According to the product label you should apply Defendor to newly seeded or sprigged turfgrass only after the third mowing or after the turfgrass seedlings have tillered and developed an adequate secondary root system. Your grass seed may have been damaged due to this application.
