I think thunder herbicide would work but is very expensive.
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.
