Back in Action: Hooded sprayers make a comeback

摘要

Sometimes what's old becomes new again. That's certainly true for hooded sprayer use. The sprayers made a strong comeback as a weed control tool in 2011 as Southern cotton growers sought additional measures to manage resistant weeds. New hood engineering is also adding to the interest. Jason Norsworthy, a University of Arkansas associate professor of weed science, says the practice became particularly important when pre-emer-gence herbicides failed to get activated in cotton and, in some cases, soybeans. He expects to see more hoods put to use this year.
