Optimizing pyroxasulfone efficacy on wild oat

野燕麦是一种对大多数常用除草剂具有抗性的有害农业杂草。 砜吡草唑是一种新的土施除草剂，可用于防治野燕麦。然而，在田间试验中对野燕麦的控制一直是可变的。有效性可能与野燕麦在种子库中的位置有关。野燕麦具有中胚轴伸长，使其能够从土壤剖面深处出现。在直接播种的田地中，种子传播将种子放置在土壤表面，而在耕作的田地中，可以在整个土壤剖面中找到野燕麦。这些试验将在温室、小区和田间试验中检查野燕麦种子位置的影响。本研究的目的是指导砜派罗克草防治野燕麦抗除草剂的研究和应用。

Wild oat is a pernicious agricultural weed that has been selected for resistance to most commonly used herbicide. Pyroxasulfone, a new soil applied herbicide may provide control of wild oat. However, control of wild oat in field trials has been variable. Efficacy may be related to the position of the wild oat in the seed bank. Wild oat has mesocotyl elongation that permits it to emerge from deep within the soil profile. In direct seeded fields, seed dispersal places seed on the soil surface while in tilled fields, wild oat can be found throughout the soil profile. These experiments will examine the effect of wild oat seed position in greenhouse, small plot and field trials. The goal of the research is to direct research and adoption of pyroxasulfone for control of herbicide resistant wild oat.
