Managing clethodim resistant ryegrass in canola with crop competition and pre-emergent herbicides

To demonstrate that crop competition afforded by a hybrid canola in combination with pre-emergent herbicides can reduce ryegrass seed set.本研究旨在证明：杂交油菜（hybrid canola）与苗前除草剂（pre-emergent herbicides）协同产生的作物竞争效应，可降低黑麦草（ryegrass）的结籽量。
