Aims: Collar rot is a fast spreading and destructive disease and is becoming more serious at seedling stage causing rot at collar region especially in area where paddy based cropping system is followed. Lack of sources of resistant in present cultivar against Sclerotium rolfsii cause serious threat to chickpea production. Therefore, the present study was carried out to evaluate the chickpea genotypes against S. rolfsii to the identification of resistant sources for further breeding program. Study Design: Randomized Block Design (RBD) with two replications were used. Place and Duration of Study: Regional Rice Research Station, Navsari Agricultural University, Vyara, between October 2019 to April 2020. Methodology: Pathogen was isolated from infected collar region of chickpea plant by directly transfer of sclerotia and infected bits on potato dextrose agar (PDA) medium. After purification, pathogen was identified by observed the colony character and sclerotia formation. The morphological characters viz., mycelial growth and mycelial characteristic were studied under high power magnification (40X) and sclerotia formation, shape and colour were studied under low power magnification (10X) from 10 days old culture. 39 chickpea genotypes were used for the studies. A field experiment was conducted during Rabi -2019-20 season. The inoculum was thoroughly broadcasted in soil @ 10g/ row. Germination per cent and disease incidence were observed. Results: Chickpea (Cicer arietinum L.) collar rot disease caused by Sclerotium rolfsii Sacc. was exhibited initial white fluffy mycelium appearance on potato dextrose agar medium. Microscopic view of mycelium was hyaline, branching, compact with septate and had a clamp connection. White sclerotia were formed after 4th days of incubation and later within 10 days after incubation it became mature and colour changed from brown to dark brown. Sclerotia appeared shiny due to presence of gummy material. Out of 39 chickpea genotypes only five viz., GJG-1713, GG-6, GJG-1509, Phule Vikram and JGK-1 were identified as moderate resistant against collar rot disease caused by S. rolfsii under inoculums inoculated rice fellow cropping system. Conclusion: Chickpea genotypes viz., GJG-1713, GG-6, GJG-1509, Phule Vikram and JGK-1 were showed moderate resistant reaction against collar rot disease caused by S. rolfsii.

“…Mehmood et al (2014) also found that aqueous root, shoot and flower extracts of T. erectus suppressed the growth of Alternaria alternata by 90, 44 and 57%, respectively. Wavare et al (2017) similarly reported that aqueous extract of T. erecta completely inhibited the growth of Sclerotium rolfsii at 1 ml/50 ml liquid medium, while treated filter paper disks by 100 mg/ml gave 19.7 mm inhibition zone. The antagonistic effect of T erecta may be due to presence of suppressive bioactive materials as distinguished by Devika and Justin (2014) who found 19 and 31 bioactive compounds in leaves and flowers of Tagetes, respectively, including Tetrad ecannoic acid, Hexadecanoic acid, 9,12 and15 Octadecatrienoic acid, Stigmasterol, Phytol and Celidoniol.…”

“…For this purpose, plant extracts and essential oils are ecological, protective, curative and antagonistic to many diseases. Therefore, plant extracts and biological agents can be used as an alternative source to control soil-borne diseases as they are a rich source of bioactive substances [ 35 ].…”

The chemical composition of essential oils (EOs) from dried and fresh flowers of Lavandula angustifolia L. (lavender), named LA 2019 and LA 2020, respectively, grown in central Italy was analyzed and compared by GC and GC-MS. For both samples, 61 compounds were identified, corresponding to 97.9% and 98.1% of the total essential oils. Explorative data analysis, performed to compare the statistical composition of the samples, resulted in a high level of global similarity (around 93%). The compositions of both samples were characterized by 10 major compounds, with a predominance of Linalool (35.3–36.0%), Borneol (15.6–19.4%) and 1,8-Cineole (11.0–9.0%). The in vitro antibacterial activity assay by disk diffusion tests against Bacillus subtilis PY79 and Escherichia coli DH5α showed inhibition of growth in both indicator strains. In addition, plate counts revealed a bactericidal effect on E. coli, which was particularly noticeable when using oil from the fresh lavender flowers at the highest concentrations. An in vitro antifungal assay showed that the EOs inhibited the growth of Sclerotium rolfsii, a phytopathogenic fungus that causes post-harvest diseases in many fruits and vegetables. The antioxidant activity was also assessed using the ABTS free radical scavenging assay, which showed a different antioxidant activity in both EOs. In addition, the potential application of EOs as a green method to control biodeterioration phenomena on an artistic wood painting (XIX century) was evaluated.
