Tuber oatgrass (Arrhenatherum elatius (L.) Presl. var.
bulbosum (Willd.) Spenn.) is a perennial grass that often
becomes a weed problem in Western Oregon. Control efforts
using glyphosate often give unsatisfactory results. The
effects of several factors on development of tuber oatgrass
were investigated. Long days and cool temperatures (16/8h,
20/10C...
Lateral diffusion of S-ethyl N-ethylthiocyclohexanecarbamate
(cycloate)¹ is essential for satisfactory weed control with injection
type incorporation in sugar beet (Beta vulgaris Linn.) production.
Previous field experience with injection incorporation has indicated
that sufficient lateral diffusion for satisfactory weed control has not
occurred under all field conditions. Researchers who have been...
Napropamide [2-(alpha-naphthoxyl)-N,N-diethylpropionamide], a
preemergence herbicide, is widely used in the United States on a
variety of tree fruits, nut crops, vegetables, and mint for annual
grass and broadleaf weed control. When napropamide has been left on
the soil surface without incorporation through irrigation or mechanical means, inconsistent results have been...
