| When The Ohio State University weed scientists announced they had discovered ALS-resistant smooth pigweed this winter, it was hard to get very excited about the news. |
| Several common weeds, including pigweed, lamb's quarters, and kochia, have been reported to be hosts for the pathogen. |
| Spartan herbicide has provided excellent control of troublesome broadleaf weeds, such as kochia, Russian thistle, and pigweed in no-till sunflower for the past several years. |
| Weed populations were dense and consisted of common lambsquarters, hairy nightshade, redroot pigweed, stinkgrass, and common purslane. |
| Annual grasses and pigweed are most sensitive when young and actively growing. |
| Therefore, a soil applied herbicide program should be used to target group II resistant pigweed. |
