Optimizing pyroxasulfone efficacy on wild oat

野生燕麦是一种有害的农业杂草，它对大多数常用的除草剂具有抗性。吡咯砜是一种新的土壤除草剂，可用于防治野生燕麦。然而，在田间试验中，野生燕麦的控制是可变的。其功效可能与野生燕麦在种子库中的位置有关。野生燕麦具有中胚轴伸长，使其能够从土壤剖面的深处出现。在直接播种的土地上，种子传播将种子放置在土壤表面，而在耕作的土地上，野生燕麦可以在整个土壤剖面上找到。这些试验将在温室试验、小块试验和大田试验中考察野生燕麦种子位置的影响。本研究旨在指导焦唑砜在野生燕麦抗除草剂防治中的研究和应用。

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.
