Response of downy brome (Bromus tectorum) and Kentucky bluegrass (Pao pratensis) to primisulfuron

Creator:

Hendrickson, Paul E.

Abstract:

Glasshouse and growth-chamber experiments were conducted to evaluate primisulfuron phytotoxicity and the influence of adjuvants on downy brome and Kentucky bluegrass. GR₅₀ (50% growth reduction) values were 0.97 ± 0.57 and 8.07 ± 1.85 g/ha for downy brome and Kentucky bluegrass, respectively. Primisulfuron was applied to downy brome and Kentucky...

Response of Striga-susceptible and Striga-resistant sorghum genotypes to soil phosphorus and colonization by an arbuscular mycorrhizal fungus

Creator:

Leytem, Alicia B.

Abstract:

Striga, a genus of obligate parasitic weeds in the family Orobanchaceae, has been identified as the most important biological factor limiting agricultural productivity in sub-Saharan Africa. Germination of Striga seeds is triggered by strigolactone root exudates from host plants. Strigolactones also induce hyphal branching in arbuscular mycorrhizal (AM) fungi, which...

Annual bluegrass (Poa annua L.) emergence under different residue management practices in perennial ryegrass and determination of resistant and susceptible annual bluegrass germination under controlled temperature and moisture

Creator:

Schuster, Matthew D.

Abstract:

With the loss of field burning the amount of crop residue that remains in perennial ryegrass fields has increased. As the amount of crop residue remaining in the field increases so does annual bluegrass. This has resulted in the increased use of herbicides to control annual bluegrass. However, this increased...

Testing the effectiveness of barley stripe rust resistance QTL detected in Mexico and the USA against a possible new race in Peru and mapping of genes conferring resistance to leaf rust and mildew in the same population

Creator:

Rossi, Carlos

Abstract:

Barley is the fourth most important cereal crop in the world because of its broad adaptation, its utility as a feedstock and for human food, and the superior properties of barley malt for brewing. Three of the most important foliar diseases of barley, on a worldwide level are: barley leaf...

Genetic factors that provide adult plant resistance against Puccinia striiformis f. sp. tritici to wheat cultivar 'Stephens' in a multilocation analysis.

Creator:

Vazquez, Maria Dolores

Abstract:

Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving increased attention in the USA since the appearance of more virulent races detected in the past decade. These races caused yield losses even in areas where the disease previously was rarely detected. Host plant resistance is the most cost effective...

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...

Phenotypic response and quantitative trait loci for resistance to Cephalosporium gramineum in winter wheat

Creator:

Quincke, Martin C.

Abstract:

Cephalosporium stripe (Cephalosporium gramineum) is an important disease limiting adoption of conservation tillage practices in the Pacific Northwest. The disease can cause severe loss of grain yield and quality in winter wheat (Triticum aestivum L.). Modified cultural practices can reduce disease incidence, but are not always dependable because of variation...

Cultural controls for suppressing Phytophthora cinnamomi root rot of blueberry

Creator:

Yeo, John R.

Abstract:

Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...

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...
