Product Overview

Defendor Herbicide is a specialty post-emergent herbicide that works to provide control over annual and perennial broadleaf weeds during the early season when other herbicides don't work. Defendor can also be applied at the same time as the first fertilizer and pre-emergent herbicides are being applied as well, giving you the most flexibility in how to control the weed population on your property, working great during both cool and warm seasons. Defendor Herbicide can also be directly mixed with liquid fertilizers and other tank sprayable products, to decrease the time required to apply all the chemicals you need to keep your property in good condition. Using a low rate, especially when compared to other post-emergent herbicides, Defendor controls some of the most obnoxious and resilient weeds that can bloom, even before they bloom.

Details

Defendor specialty herbicide gives you early cold season control of unattractive dandelions, clover and other annual and perennial broad-leaf weeds. The herbicide provides lawn care contractors and golf course managers a first crack on weed control and additional time to complete the first applications of the season. Labeled for use on turf during both the cool and warm seasons, the product offers strong post-emergence weed control in a adaptable formulation.

Defendor, with its active ingredient of florasulam, is absorbed via the leaves, shoots and roots of susceptible weeds. It works as an ALS inhibitor, stopping enzyme synthesis and cell division in the weeds. When applied early in the season, development of susceptible weeds will be checked immediately and the weeds will die within two to four weeks. The herbicide provides activity at extremely low use rates (0.013 lb. a.i./A) when compared with other post-emergence herbicides. In addition, when applied in early spring, the product prevents dandelions from growing, greatly reducing callbacks, increasing customer satisfaction, and save time and money.

Q
Can Defendor Herbicide be used in vegetable garden areas?

Is there any residual effect to soil? Can I use this product to control weeds in vegetable gardening. Will it prevent vegetable seeds from germinating?

A

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.

Q
I seeded my lawn a week ago. Now the lawn care company put down Defendor. Will my grass seed come up?
A

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.
