Pigweed Needed!

This is from OSU Extension.  If you have a pigweed problem help them out!

We are trying to get an assessment of herbicide resistance in Ohio pigweed populations, including

 smooth and redroot pigweed,

waterhemp,

and Palmer amaranth.

One mechanism for this is to sample small pigweed plants from fields in May and June, bring them back to our greenhouse, and treat them with the herbicides of interest.  We obviously need help finding the pigweed populations. As you see pigweed emerge over the next month, it would be extremely helpful to us if you would give us a call or email, and we will make arrangements to collect plants.

We need to collect plants that are ideally no more than an inch or two tall, and they can be from field margins where herbicides were not applied as well as within the field. Fields with a history of pigweed control problems are obviously especially good candidates for this research.
