Unfortunately, chameleon or Saururaceae, h. cordata, is an invasive species that is very aggressive and difficult to control. Because this plant spreads from underground rhizomes, you will not be able to control it by pulling or mowing. I have not been able to find any products that specifically list this plant on the label, and there is very little information from US sources on management of this plant. We would recommend trying RoundUp QuikPro, a non-selective herbicide with two active ingredients, or Southern Ag Brush Killer. These are excellent active ingredients that will damage most plants. You would want to give either product 10-14 days to see results. Be sure to give the plants enough time to die completely before tilling or disturbing the soil where they were growing.
Crossbow should not harm established trees but may damage younger trees if applied directly to them. To avoid injury, do not apply directly on or within the drip line of smaller trees and avoid the foliage and any exposed roots of mature trees. It is best to carefully spot treat the target plants to avoid injury to your desirable trees.
Crossbow Herbicide can be used now, if necessary, as long as temperatures are above 45 degrees. Crossbow Herbicide will be effective in 45 to 85 degrees Fahrenheit.

Pigweed can be difficult to treat around edible crops. Products that contain glyphosate such as RoundUp can be used to spot treat actively growing weeds. For more products that can be applied as an over spray or those resistant pigweed varieties, we recommend contacting your local Master Gardener for additional recommendations. Please let us know if they suggest a product that you cannot locate on our website and we will make an effort to locate the product for you.
We apologize, but we are not aware of any studies that have been done to determine what the effects of Crossbow might be on a wild turkey population.
