“…These results are similar to those reported by Subbiah et al, (1996), Voltiolina, (2001 and Zaki and Waleed (2008). In this respect, R. solani is considered as important and dangerous soilborne fungal pathogen affecting different medicinal and aromatic plants (Minuto et al, 1997, Hilal et al, 1990, Hilal et al, 1994, Hilal et al,1998, Hilal et al, 2009, Conway et al, 1992and Conway et al , 1997, Machowicz-Stefaniak et al, 2002, Kalra et al, 2004, Yadav and Anamika, 2005and Nada, 2014and Nada, 2015.…”

Isolation trials from infected sage seedlings and plants, growing in Ismailia, North Sinai and Qalubyia governorates, showing symptoms of damping-off and root rot diseases yielded Fusarium oxysporum, F. solani, Macrophomina phaseolina, Pythium ultimum and Rhizoctonia solani. However, R. solani recorded the highest frequency in isolation (52.6%), followed by Fusarium solani (24.6%), while M. phaseolina was the least (3.5%). These fungi were found to be pathogenic to sage seedlings. Rhizoctonia solani followed by F. solani were the most virulent fungi, causing the highest damping-off incidence. Three silicon (si) sources, i.e. calcium silicate, potassium silicate and sodium silicate with four concentrations (25, 50, 100 and 200 ppm) significantly inhibited the in vitro growths of R. solani in different degrees. Potassium silicate was more effective than the other silicon sources tested, and completely inhibited mycelial growth at 200 ppm. Soaking seeds (30 min.) and /or dipping treatment for seedlings (30 min.) in each of these silicon sources (400 ppm) or the fungicide Vitavax /Thiram (3 g/l water) gave sufficient control to R. solani diseases, i.e. damping-off in greenhouse and nursery as well as root rot in the field .Also, they recorded significant increases in growth parameters of seedlings (height & root length) and mature plants (height & no. of branches /plant). Potassium silicate, however, was significantly the most effective treatment among other silicon sources. Using calcium silicate and potassium silicate as dipping treatment for seedlings, gave significant increases in yields of fresh herb and essential oil content. Vitavax /Thiram treatment in the nursery and field experiments was more effective than silicon treatments, except with potassium silicate in the field, which increased fresh herb weight per plant and essential oil content than the fungicide.

“…Rhizoctonia web blight is documented in the literature as a destructive, yield-reducing disease on several com- mercially important plant species, such as common bean ( 12), soy bean (39), rosemary (7), verbana (17), and container-grown azalea (8). The disease also was reported on mint in Florida (3), India (22), and China (11); however, these reports presented limited information about the extent of damage or etiology on mint. To tbe best of our knowledge, this is the first report of R. solani causing web blight on any crop in Israel, and specifically on mint, and the first comprehensive description of the disease etiology on this particular crop.…”

Nitzan, N., Chaimovitsh, D., Davidovitch-Rekanati, R., Sharon, M., and Dudai, N. 2012. Rhizoctonia web blight-A new disease on mint in Israel Plant Dis. 96:370-378.Mentha longifolia is produced in and exported from Israel with annual revenue of US$16 million. In 2010, a severe epidemic of unknown etiology reduced growers' retums up to 50%. Disease symptoms included water-soaked lesions, necrosis, and web-like myeelia on plants. Two isolates (JV-1 and BS-1) from randomly selected symptomatic plants were identified as members of Rhizoctonia solani anastomosis groups 1-lB and 4HG-I, respectively. The fitness of JV-1 and BS-I interacted with temperatures between 17 and 35°C; JV-1 grew faster and was more aggressive (P < 0.05) at lower temperatures (<24°C), BS-I grew faster and was more aggressive at higher temperatures (>30°C), and the two isolates performed similarly at intermediate temperatures. Disease developed fastest at 24 to 28°C. Yield was reduced between 46 and 100%. In all, 71.5% fewer plants recovered from disease developing at 24 to 28°C than at 17 to 23 or 30 to 35°C. The relationship of disease to relative humidity (RH) fit a quadratic model (P < 0.0015, R-= 0.98). Disease was most severe at 100% RH, decreasing by 1.3-, 1.9-, 3-, 4.5-, and 10.5-fold with the reduction of RH from 100% to 88, 76, 69, 55, or 49%, respectively. This is the first report of Rhizoctonia web blight in mint in Israel.

Mints are perennial aromatic herbs used both for medicinal and aromatic purposes. Flora of Pakistan has reported six species of genus Mentha. Taxonomy of genus Mentha is more complex and confusing due to inter specific hybridization. The present research is the first documented report from Pakistan for the purpose to dissect Mentha specimens using molecular tools. A total of 17 SCoT and SSR markers used to dissect genetic diversity among 41 Mentha specimens. The results revealed substantial variation among Mentha specimens. The molecular data analyzed through NTSYS and Power marker software's. Dendrogram constructed on the base of similarity coefficients generated using weighted pair group method of arithmetic means (UPGMA) recorded high level of polymorphism. Polymorphic Information Content (PIC) for molecular markers recorded in the range of 5-8. Mean genetic distance (GD) was estimated in the range from 0.35% to 100%. The minimum and maximum GD recorded in one combination each as P2-P4 and M41-P10. The present study was explored the efficiency of SCoT and SSR markers for evaluating the genetic diversity of medicinal plants. The present research was concluded that both morphological and molecular dendrogram determined considerable level of diversity among Mentha species.Furthermore, specific primers and DNA chloroplast technology could be needed for further molecular analysis to refine the data more up to varietal level.
