Biobased mulch spray curbs weeds in vegetable crops

Biobased sprayable mulch (BSM) films are a potential alternative to herbicides, polyethylene plastic mulch film, and hand weeding for specialty crops. Researchers at the American Society for Horticultural Science have developed a series of BSM films using locally available biomaterials and tested their effects on weeds and crop yield during a total of seven greenhouse or field trials between 2017 and 2019 in Nebraska, U.S..
