DISEASE & WEED CONTROL
A different tool in fighting
herbicide resistance
RESEARCHERS WANT TO KNOW WHAT CONDITIONS TRIGGER
WEED EMERGENCE
BY CHRIS KOGER
MANAGING EDITOR
U
niversity of Idaho researchers are using newly
acquired equipment to study when temperatures are
ideal to kick off the growing cycle of different weeds.
The goal is to determine the best time to apply
herbicides, and eventually tackle the growing problem of
herbicide resistance.
The study at the University of Idaho (UI) Kimberly
Research and Extension Center in Moscow, Idaho, uses
a new thermogradient table, made possible by a grant
of about $24,000 from the Pacific Northwest Herbicide
Resistance Initiative.
The project began in October. Albert Adjesiwor, a UI
Extension weed specialist, said the current project is
focusing on Italian ryegrass, wild oat and cheatgrass,
which are problematic grassy weeds in small grain
Italian ryegrass seeds are monitored by University of Idaho researchers to
see when they will germinate when subjected to different temperatures by
using a thermogradient table. Photo by Chandra Maki.
