Rivers, MB | Have had mixed results last few years killing vol. sunflowers in hard red spring wheat. What do you guys use?

east central south dakota | Wolpack advanced is the cheapest at 20 oz
Huskie seems to work also. |

NWMN | I've had good control with 2-4D. Also Affinity works very well, just don't skimp on the rate. |

Rivers, MB | Not familiar with those trade names. Don't have them in Canada. What's the chemical name in those? thanks

Rivers, MB | I have used Buctril M (bromoxinyl + MCPA) and Infinity (pyrafentrazone???). Both seemed to slow the vol. sunflower down but it seemed to grow through it for a while. They never ended up growing taller than the wheat which I guess should be good enough. However, I would have thought that the sunflower should wither and die soon after taking in chemical. Sunflowers (when growing a whole field of them) seem to be highly susceptable to any small amount of chemical drift or even the smell of chemical in the air so I am surprised that not any herbicide that kills broadleaf weeds in wheat does not totally eliminate vol. sunflowers.

Southeast Colorado | amazing that it takes something better than 2-4-D to kill a volunteer when it will sure mess up the ones a guy tries to grow. |
