Ghaderi F (2019) Incidence of root and crown rot disease of black cumin in the southwest of Iran. Plant Pathology Science 8(2):1-8. DOI: 10.2982/PPS.8.2.1    Introduction: Black cumin, an annual flowering plant in the family Ranunculaceae, is a medicinal herb with many pharmacological properties. Crown and root rot disease of this plant has been reported in most countries worldwide. This stud...

Interaction of Pratylenchus penetrans and Rhizoctonia fragariae in Strawberry Black Root Rot.

A split-root technique was used to examine the interaction between Pratylenchus penetrans and the cortical root-rotting pathogen Rhizoctonia fragariae in strawberry black root rot. Plants inoculated with both pathogens on the same half of a split-root crown had greater levels of root rot than plants inoculated separately or with either pathogen alone. Isolation of R. fragariae from field-grown ...

Brown Root Rot Disease in American Samoa

Phellinus noxius causes root and lower stem rot of woody plants throughout the South Pacific region. Its hosts include rubber, mahogany, cacao, and many timber, fruit and landscape trees. Though endemic to the tropics, we found no reports describing brown root rot disease in native forests, exclusively. Incidence, distribution and host range of P. noxius were measured in primary and secondary r...

Comparison of Pratylenchus penetrans Infection and Maladera castanea Feeding on Strawberry Root Rot.

The interaction of lesion nematodes, black root rot disease caused by Rhizoctonia fragariae, and root damage caused by feeding of the scarab larva, Maladera castanea, was determined in greenhouse studies. Averaged over all experiments after 12 weeks, root weight was reduced 13% by R. fragariae and 20% by M. castanea. The percentage of the root system affected by root rot was increased by inocul...
