Global wheat production is threatened by the escalating selection of herbicide resistant weed populations. The continuing evolution of herbicide resistance in major crop weeds is a driving force to develop new weed control strategies in field crops and to preserve the utility of herbicides.

This project will concentrate on the potential benefits of the use of chaff carts and bale direct systems to reduce weed infestations in wheat-production systems in the Pacific Northwest (PNW). Their efficacy to control weeds is unknown because the proportion of weed seed per species collected by the combine and ejected with the chaff or straw has not been investigated.

The intern will assist in field and laboratory work to address the following objectives: 1) Evaluate chaff collection and chaff plus straw collection at harvest to reduce weed infestations, 2) Evaluate seed production, seed height, and seed retention of important weed species at harvest.



For this project, the intern will be expected to spend 15-20 hours per week outdoors and 20-25 hours per week in an indoor lab.

Among the different tasks where the student intern is expected to help are:

1) Collect weed plants from crop fields near CBARC once per week before harvest,

2) Evaluate seed production and seed retention of the collected plants,

3) Help to sample weeds in the field.

An interest in agronomy and/or in weed science is desirable.

The intern, as a member of a team, will be expected to help and learn from other activities/projects that the Weed Science Program is developing at CBARC.
