Abstract
A lack of information regarding weed control, relative to conventional
systems, has left organic growers largely on their own when devising weed
management systems for organic crops. As interest in organic weed management
increases, researchers need more information regarding the type and number
of weed control practices undertaken on organic farms. A survey of certified
organic growers was conducted in five states in the northwest United States
to identify organic weed management programs and what grower and
farm-operation characteristics were factors in weed management program
design. Three types of weed management programs, with varying diversity in
weed control practices, were identified. Stepwise binary logistic regression
indicated that the likelihood of an organic grower using a more-diverse weed
management program increased if the grower engaged in grain production and
as the number of crops produced on an organic farm operation in 1 yr
increased. The probability of operating a more-diverse weed management
program also increased as a grower's education level increased. Organic
hectarage operated was positively correlated with weed management program
diversity, and with the adoption of cultural controls. Additionally,
awareness of weeds as a factor causing yield loss was correlated with
increased weed management program diversity. An increased awareness among
researchers of the differing needs and abilities of organic growers in
managing weeds on their farms will improve communication and outreach
efforts when assisting growers with designing organic weed management
programs.
