Bio-control of root rot disease in vanilla
… var. vanillae (Tucker) Gondon is known to cause root rot in Vanilla planifolia Andrews in most regions where it is grown, including the major plantations in Xishuangbanna, Yunnan Province of China. This is of serious economic concern to the Province since the vanilla flavouring extractable from …

Inheritance of virulence in the root rot pathogen Phytophthora sojae
The oomycete Phytophthora sojae causes stem and root rot of soybean plants. The interaction of pathogen avirulence (Avr) and host resistance (R)-genes determine the disease outcome. The Avr3a mRNA transcript level is variable among P. sojae strains and determines virulence towards the R-gene Rps3a. …

Aspects relating to the spread and survival of Phellinus root rot
Active and inactive edges of a Phellinus weirii root rot center were compared to see if the reason for the inactivation of part of the center could be explained. The inactivation could not be shown to be the result of differences in root contacts or soil factors. Hypovirulence caused by a dsRNA …

QTL mapping of Phytophthora root rot resistance and aphid resistance in soybean
… as soybean cyst nematode (SCN), Phytophthora root rot (PRR), sudden death syndromes (SDS) and soybean aphids are threatening soybean production and plant health. Three independent projects were performed to identify genetic resistance against PRR, caused by Phytophthora sojae; to identify …

Interactions of post emergence herbicides, strobilurin fungicides and Rhizoctonia root rot of soybean
Rhizoctonia root rot, caused by Rhizoctonia solani, is a major disease of soybeans in the north-central United States. The emergence of glyphosate resistant weeds and the payment premium for growing non-GMO soybeans has increased the use of non-glyphosate herbicides. However, some of these …

Biological control studies of Phytophthora Parasitica root rot of boxwood using multiple antagonists
Phytophthora parasitica is an important root rot pathogen of American and English boxwood, Buxus sempervirens and B. sempervirens var. suffruticosa, respectively, shrubs used extensively in the landscape in Virginia and North Carolina. Studies were undertaken to screen microorganisms for antagonism …

Evaluation of Soil Compaction, Plant Density, and Resistance to Phytophthora Root Rot in Soybeans
Phytophthora root rot, caused by Phytophthora megasperma f. sp. glycinea Kuan and Erwin, is a soil-borne fungal disease of soybean Glycine max (L.) Merr. . Studies were conducted to determine the effects of soil compaction on phytophthora incidence, to determine if reduced soybean stand due to …

Survival and chemical control of Cylindrocladium spp. inciting root rot of black walnut seedlings
… resulted in no recovery of Cylindrocladium crotalariae microsclerotia, but rewetting soils to near field capacity for 1 to 4 wk before assay resulted in partial recovery from the air drying-induced decreased germinability. Numbers of germinable C. crotalariae microsclerotia (assayed at 26 C) …

The etiology of root rot and decline of English boxwood (Buxus sempervirens cv. suffruticosa L.)
… in most cases, at the point where lateral roots emerge from main roots while F. oxysporum was isolated mainly from root tips. Phoma sp. was isolated in the spring months but was not recovered at any other time. Foliar infection did not have a significant role in the decline syndrome as the …
