Seed Meals from Allelopathic Crops as a Potential Bio-Based Herbicide on Herbicide-Susceptible and -Resistant Biotypes of Wild Oat (Avena fatua L.)

Wild oat is a nuisance monocot weed mainly in cereal canopies. The increasing problem of herbicide resistance and the implementation integrated pest management includes use seed meals from species with allelopathic potential. This study aimed to assess efficacy as an environmentally friendly alternative for control herbicide-susceptible (S) -resistant (R) wild biotypes. A pot experiment was carried out under greenhouse conditions at Swojczyce Research Training Station Wroc?aw (Poland) determine impact Fagopyrum esculentum, Lupinus luteus, Ornithopus sativus, Phacelia tanacetifolia, Raphanus sativus var. oleiformis Sinapis alba two concentrations—1 3%. lowest percentage seedling emergence recorded after application S. meal. Seed reduced both S R biotypes by approximately 82 61 points, respectively, limited initial growth F. O. R. generally did not decrease number seedlings. Almost all inhibited aboveground parts susceptible biotype greater extent than treatment.
