Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Preplant soil treatments were implemented to determine effects on populations of potentiallypathogenic Fusarium and potentially disease-suppressive Trichoderma spp. as well as root colonization by these and other selected fungi on healthy-appearing, bare root 2-0 western white pine seedlings at the USDA Forest Service Nursery, Coeur d'Alene, Idaho. Soil treatments included...

Creator:: Freitag, Michael
Abstract:: The biocontrol potential of Trichoderma harzianum Rifai, Trichoderma polysporum (Link.:Pers.) Rifai, Scytalidium aurantiacum Klingstr. et Beyer or a Penicillium sp. against Trametes versicolor (L. :Fr.) Pilat, Neolentinus lepideus (Fr.) Redh. et Ginns, Postia placenta (Fr.) M.Lars. et Lomb. and Irpex lacteus Fr. was evaluated using agar plate, soil bottle and...

Creator:: Xiao, Ying
Abstract:: While microbial colonization of wood is presumed to be characterized by a myriad of interactions between numerous organisms, studying these processes is often difficult owing to the opaque nature of the wood and the inability to readily distinguish among the many species colonizing the material. One method for enhancing the...

Creator:: Nelson, Mark E.
Abstract:: Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...

Creator:: Liu, Jiajian
Abstract:: The biocontrol potential of Trichoderma harzianum strains B-2A, B-8A, B-4B, B-15B, and B-41 and Serratia plymuthica was evaluated using agar plates and wood wafers of unseasoned ponderosa pine (Pinus ponderosa laws). All five isolates of Trichoderma harzianum and Serratia plymuthica could inhibit stain fungi growth in agar plates and exhibited...

Creator:: Canessa, Edwin
Abstract:: Small size wood assays were utilized to study the effect of added nutrients to the wood on the interactions of Trichoderma harzianum Rifai and two wood decay fungi, Trametes versicolor (white rot) and Gloeophyllum trabeum (brown rot). Weight losses related to time of exposure were monitored as a measure of...

Creator:: Funahashi, Fumiaki
Abstract:: In horticultural nurseries for container-grown plants, production and sales have been threatened by the presence of a quarantined plant pathogen, Phytophthora ramorum (causal agent of sudden oak death). Infested nursery beds are an important source of P. ramorum, which can initiate disease through movement with surface water to infect roots...
