Small broomrape (Orobanche minor) management using wheat (Triticum aestivum) as a false host

Creator:: Al-thahabi, Salam A.
Abstract:: Small broomrape (Orobanche minor) is an obligate, chlorophyll-lacking parasite that parasitizes red clover (Trifolium pratense) roots. This study was conducted to develop and implement an integrated, biologically based control program for small broomrape by using wheat as a false host to reduce the soil seed bank. The relationship between temperature...

Nodulation problems with alfalfa and subterranean clover on selected Oregon soils

Creator:: Attavirojana, Pitsanu
Abstract:: Two separate investigations were carried out. The first experiment on subterranean clover (Mr. Barker) was conducted in the field and greenhouse on the Steiwer soil. The second experiment on alfalfa (DuPuits) was conducted in the greenhouse on selected eastern Oregon soils. The purposes of the first experiment were to determine...

Isolation and Pathogenicity of Naturally Occurring Entomopathogenic Fungi to Clover Root Borer (Coleoptera: Curculionidae: Scolytinae), a Pest of Red Clover Seed Crops

Creator:: Lestari, Anis S.
Abstract:: Entomopathogenic fungi are cosmopolitan microbial pathogens that cause fungous diseases in a wide range of insects via spore infection. Due to their natural enemy status, they have tremendous potential for use as microbial control agents against insect pests, especially subterranean pests for which few management options are available. The clover...

Integrated small broomrape (Orobanche minor Sm.) management in red clover (Trifolium pratense L.)

Creator:: Ross, Kyle C.
Abstract:: Small broomrape, a holoparasitic weed, is a relatively new weed introduction in the Pacific Northwest that has contaminated a limited number of red clover fields in Oregon. Greenhouse and field studies were conducted to evaluate small broomrape response to common crop and weed species in the Pacific Northwest. Host species...

Seasonal abundance, distribution, and migration of the clover aphid, Nearctaphis bakeri (Cowen) in red clover

Creator:: Dreves, Amy J.
Abstract:: Four sampling techniques were evaluated to estimate clover aphid, Nearctaphis bakeri (Cowen), abundance in red clover fields in the Willamette Valley. The Berlese funnel method detected one to four times more aphids than other sampling techniques. Visual assessment often underestimated the high aphid densities during the flowering and seeding of...

Lodging control and yield enhancement in Morex spring barley with paclobutrazol treatment

Creator:: Morrison, Laura A.
Abstract:: Lodging in cereals can cause significant decreases in yield. It is both a problem in susceptible cereal cultivars with a tall-stemmed, weak-strawed growing habit and in lodging-resistant cereal cultivars when they are grown under high-nitrogen, high-moisture regimes. Plant growth regulators (PGR's) are chemical growth retardants that offer a method of...
