Seven Pseudomonas isolates were isolated from different locations of south Gujarat. Based on the morphological, biochemical and physiological characterization of these isolates, four bacterial isolates were identified as Pseudomonas aeruginosa (PaWP, PaWS, PaRS and PaNS) and three as P. fluorescens (PfWN, PfRB and PfNC). All the isolates were able to grow in 2 to 10% NaCl but, failed to grow at 12% concentration and recorded growth from 10 to 42°C temperature. All the isolates grew in 6 to 8 pH range but failed to grow at 4, 5 and 10 pH. Bio-efficacy of the seven native strains of Pseudomonas spp. Was compared along with local commercial available biopesticides i.e. P. fluorescens (Aumgene, Pramukh and Pantnagar) and Hinosan. Three times spraying of P. aeruginosa Rambhas Strain at 0.6% (2×109 cfu/ml) at 15 days interval, starting at 21 days of transplanting was found significantly effective in the management of the leaf blast of finger millet (Magnaporthe grisea (Cke) Sacc.) by lowering disease intensity and increasing grain yield as well as fodder.Keywords

Total average PDI of Navsari district was recorded 12.96 and 36.85 respectively, at flowering stage and pod formation stage of crop. The average length of conidia was maximum 49.76 μm in the samples collected from KVK, Navsari area, while minimum 38.08 μm was in the samples collected from Pethan village. Maximum breadth of conidia 21.55 μm in KVK, Navsari area and minimum 18.00 μm in Pethan village of Navsari district. The average length and breadth of conidia of all villages 43.73 μm length and breadth 20.24 μm, respectively. While length/breadth index was maximum 2.30 μm in KVK, Navsari area followed by Abrama 2.09 among the collected samples. In case of conidiophore maximum length in KVK, Navsari area 68.43 μm and minimum length in Crafeat area 58.83 μm. While, maximum length of conidiophores was recorded in KVK, Navsari area 6.78 μm and minimum in Cafetra 8.48 μm.

Two variety and thirteen germplasms of fenugreek (Trigonella-foenum graecum L.) were screened against powdery mildew under field condition. One germplasm FGK-94 was found resistant reaction to powdery mildew. While, three gremplasms FGK-97, FGK-98 and FGK-103 found to be moderately resistance. FGK-95, FGK-96, FGK-99, FGK-100, FGK-101 and FGK- 102 showed moderately susceptible reaction. Two variety Hissar sonali, RMT-361 and one germplasm FGK-104 showed susceptible reaction.Keywords

The rhizospheric soil samples were collected from different cultivated agricultural fields from Bharuch and Narmada districts and the mycoflora were isolated by serial dilution plate technique. Total eight isolates of Trichoderma viride, Trichoderma harzianum and Trichoderma longibrachiatum were isolated on Potato Dextrose Agar medium. The green coloured colonies were identified by comparing with taxonomic key. They were purified by single spore isolation method and maintained on PDA slants at 40C in the refrigerator at Department of Pl.Pathology, NMCA, NAU, Navsari. Soil borne Pathogenic fungi viz., Sclerotium rolfsii, Macrophomina phaseolina and Fusarium oxysporum were isolated from the respective diseased plants during field survey in Navsari Agricultural University farm, Navsari. The antagonistic efficacy against test pathogen was evaluated by dual culture plate technique. Among all 8 Trichoderma isolates, The Trichoderma harzianum NCJD8 isolate has showed 24.17 mm mycelial growth with 73.15 per cent inhibition of Sclerotium rolfsii, where in case of Macrophomina phaseolina, Minimum mycelial growth (32.67 mm) of test pathogen was recorded in T. longibracheatum NCJD2 isolate with 63.70 per cent inhibition which was statistically at par with T. viride NCJD6 (34.50 mm) with 61.67 per cent inhibition and when it comes to Fusarium oxysporum, T. harzianum NCJD5 showed minimum mycelial growth and highest per cent growth inhibition (75.56%) with 22.00 mm colony diameter of the pathogen after seven days of incubation which was statistically at par with isolate T. harzianum NCJD1 (72.96%) with 24.33 mm colony diameter.Keywords
