Creator:: Bratsch, Anthony D.
Abstract:: Field experiments were conducted with cauliflower (Brassica oleracea var. botrytis cv. Snowball Y ) to determine crop development, yield, quality and maturity response to various seasonal water levels, and to specific water stress timing in relation to curd initiation. The effects of nitrogen rate, timing, and source and the application...

Abstract:: A series of experiments were conducted from 1983 to 1985 to determine the effects of dinoseb [2-(1-methylpropyl)-4,6-dinitrophenol] on winter wheat (Triticum aestivum L. em Thell) yields. Field trials on dinoseb timing and dinoseb plus supplemental pesticides were established in an effort to elucidate the possible factors involved in the yield...

Creator:: Amerasinghe, A. A. L.
Abstract:: Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the most troublesome perennial weeds of agricultural lands in tropical and some temperate regions. This research sought to determine the effects of timing of herbicides, shading, and soil moisture on plant population growth and tuber production of purple nutsedge...

Abstract:: Mayweed chamomile (Anthemis cotula L.) is an annual weed in the Asteraceae family that is commonly found in fields of the Pacific Northwest. Acetolactate synthase (ALS)-inhibiting herbicides are frequently used to control a broad spectrum of weed species including mayweed chamomile. Seeds of four biotypes of mayweed chamomile (KJ, KL1,...

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...
