Chilli crop is attacked by more than dozen diseases of fungal, bacterial and viral nature leading to great loss to cultivators. Among those diseases, damping off of chilli incited by Pythium spp. is responsible for 90 per cent mortality either as pre or post-emergence damping off in nurseries and field conditions. Results indicated that the pre-emergence damping off was responded with significantly lowest seed rot found in PATH-34 (42.4 %) and this variety was at par with PATH-32 (60.3 %), PATH-24 (60.3%), PATH-9 (61.1%), PATH-7 (60.02%), PATH-6 (65.00 %) and PATH-26 (65.0%). Significantly highest seed mortality was noted in 58 entries where number of rotten seeds ranged from 69.6 to 96.7 per cent. Significantly higher germination in sick soil was PATH-34 (28.63 %), PATH-9 (16.41%), PATH-24 (15.61%), PATH-32 (15.61 %), PATH-6 (11.71 %), PATH-7 (11.71%) and PATH-26 (11.71%). While 58 entries have significantly less germination in sick soil. However, the post-emergence damping off the genotypes PATH-6 (22.86%), PATH-9 (22.86%) and PATH-34 (22.86%) were resistant (R) reaction with seedling mortality and the moderately resistant (MR) reaction of seedling mortality were PATH-24 (40.16%), PATH-32 (40.06%), PATH-30 (36.17%) and PATH-07 (31.46%). The 12 germplasm lines expressed moderately susceptible (MS) reaction having post-emergence mortality from 40.2 to 56.8 (%). The 18 germplasm lines expressed susceptible reaction (S) having 56.9 to 73.4 (%) post emergence mortality. The highly susceptible reaction (HS) was expressed by 28 entries having post-emergence mortality from 73.5 to 90 (%).Keywords

Evaluation of different fungicides and biocontrol agents revealed that all the fungicides as well as bicontrol agents have significantly improved germination (%) over untreated control. Combination of seed treatment (T9) with thiram+ carbendazim + T. viride + Rhizobium and soil application of T. viride was significantly superior and was at par with T8, T7, T6, T5, T4 and T2. All the fungicides alone or incombination with T. viride + Rhizobium seed treatment were significantly superior over control and were at par.Keywords

Background and objective: Invasive fungal infections (IFI) are increasingly diagnosed in the immunocompromised patients due to improved diagnostic modalities. Major risk factors for IFI are diabetes mellitus, HIV infection, neutropenia, prolonged use of corticosteroids; recipients of bone marrow or solid organ transplant, haematological malignancies and inherited immunodeficiency disorders. In systemic fungal infections the outcome of the disease depends more on the host factors rather than the fungal virulence. Zygomycosis (Mucor) is the most lethal opportunistic fungal infection particularly among patients with diabetes mellitus and haematological malignancies. Rhino cerebral zygomycosis most common and fulminant type of zygomycosis leads to fatal consequences within a week of onset. Diagnosis of fungal infection include routine microscopy, cultures and advanced serological methods. Management of fungal infections depending on the type of infection and aetiologic agents. Antifungal agents have varying spectrum of activity, dosing, safety profiles and costs. Common antifungal agents used are polyene (AmphotericinB), Azole (Fluconazole, Itraconazole, and Voriconazole etc), Echinocandins (caspofungin, anidulafungin etc). Along with antifungal drugs treatment of co-morbid disease is important for better outcomes.
Methods: This was a prospective observational study performed in hospitalised patients. Patients hospitalised with suspected fungal infection or the patients hospitalised for any illness and suspected to have fungal illness during course of stay were screened and worked up in detail for fungal aetiology. Radiologicaly suspected fungal infection cases were worked up and specific samples collected for microbiology. Patient who were diagnosed to have definitive invasive fungal disease were included in the study.
Results: In present study 34 patients of conformed IFI were included and observed. 15 patients were diabetic with IFI. Male patients 19(55.9%) in age group12 to 70 years with the average age being 47.15 years were predominantly affected. Most common risk factor in the present study was diabetes mellitus which was noted in 15 out of 34 cases(44.11%). Mucor is commonest fungus in diabetic patients(60%) followed by aspergillus (26.66%).Naso-orbital infection was most common site of affection. Mortality was 46.7% in diabetic patients with fungal infections. Better outcomes observed in patients treated with combined medical and surgical treatment (64.3%) than medical treatment 45% alone.

Celastrus paniculatus Willd., is an important medicinal plant. However, over exploitation of C. paniculatus has posed a serious threat to its existence. Therefore, in-vitro plant regeneration protocol was developed using nodal segment and shoot tip explants in Celastrus paniculatus Willd. Out of different explants nodal segment was found to be the most suitable for callus induction and further shoot regeneration. Highest callusing was obtained on MS medium supplemented with 1.0 mg/l BAP and 0.1 mg/l indole acetic acid (IAA). Earliest shoot initiation (10.6 days), highest per cent shoot multiplication (85.6%) and maximum number of shoots per explant (5) was observed in nodal segment explant on MS medium supplemented with 2.5 mg/l benzylaminopurine(BAP)and 0.5 mg/l thidiazuron (TDZ). Developed shoots were subjected to ischolar_maining on 1/2 MS medium with 1.5mg/l IBA(indole butyricacid)and the ischolar_mained plants were hardened in polycarbonated polyhouse.Keywords
