First Report of a Bacterial Disease on Creeping Bentgrass (Agrostis stolonifera) Caused by Acidovorax spp. in the United States

Establishment of transgenic herbicide-resistant creeping bentgrass (Agrostis stolonifera L.) in nonagronomic habitats.

Concerns about genetically modified (GM) crops include transgene flow to compatible wild species and unintended ecological consequences of potential transgene introgression. However, there has been little empirical documentation of establishment and distribution of transgenic plants in wild populations. We present herein the first evidence for escape of transgenes into wild plant populations wi...

Expression of a Novel Antimicrobial Peptide Penaeidin4-1 in Creeping Bentgrass (Agrostis stolonifera L.) Enhances Plant Fungal Disease Resistance

BACKGROUND Turfgrass species are agriculturally and economically important perennial crops. Turfgrass species are highly susceptible to a wide range of fungal pathogens. Dollar spot and brown patch, two important diseases caused by fungal pathogens Sclerotinia homoecarpa and Rhizoctonia solani, respectively, are among the most severe turfgrass diseases. Currently, turf fungal disease control ma...

Cytochrome P450 Inhibitors Reduce Creeping Bentgrass (Agrostis stolonifera) Tolerance to Topramezone

Creeping bentgrass (Agrostis stolonifera L.) is moderately tolerant to the p-hydroxyphenylpyruvate dioxygenase-inhibiting herbicide topramezone. However, the contribution of plant metabolism of topramezone to this tolerance is unknown. Experiments were conducted to determine if known cytochrome P450 monooxygenase inhibitors 1-aminobenzotriazole (ABT) and malathion alone or in combination with t...

Effect of Azoxystrobin on Dollar Spot Disease Development in Creeping Bentgrass (agrostis Stolonifera) and Kentucky Bluegrass (poa Pratensis)

Dollar spot disease, caused by the fungus Sclerotinia homoeocarpa F.T. Bennett is common on intensively managed creeping bentgrass (Agrostis stolonifera L.) and annual bluegrass (Poa annua L.), and other turfgrasses. Frequent chemical applications during the growing season are made to control this disease. Previous observations state that application of fungicides such as azoxystrobin can incre...
