Abstract:Foot rot of rice caused
by Fusarium moniliforme
(Fusarium verticillioides)
has become a major problem on certain cultivars of rice under Punjab
conditions. The pathogen produces different types of symptoms (elongation,
stunting or both and death of plants) in nursery as well as in field. The
influence of the cultural media on morphological, cultural characteristics and
growth rate of F. moniliforme on four
different media: Potato dextrose agar (PDA), Soil Extract Agar (SEA), Spezieller Nahrstoffarmer (SNA)
and Water Agar (WA) were studied and macro-conidial features were observed on
carnation leaf Agar (CLA) medium. The pathogen was isolated from the foot rot
infected Basmati plants, collected from different agro-ecological zones of
Punjab. The colony color in PDA and SEA was varied between whitish to pinkish
whereas in SNA and WA media it was observed to be white. The maximum colony
diameter of Fusarium moniliforme
was observed on PDA with 82.33 mm diameter and growth rate of 25.72 mm/
48hrs, followed by SEA with colony diameter of 79.67 mm and growth rate of
19.65 mm/48hrs. Poor growth rate was observed on SNA with 16.55mm/ 48hrs
growth rate and 47.98mm colony diameter. Lowest was observed on Water Agar
(WA) with 35 mm colony diameter and 6.5mm/ 48hrs growth rate. Mycelial growth was dense and fluffy on both PDA and SEA.
Moderate and sparse to thin growth on SNA medium was observed. No chlamydospores were observed on all the media under
study. Sporulation was highest in SNA (6 x105 spores/
ml), followed by SEA (5.7 x105 spores/ ml) and PDA (4 x105 spores/
ml). But the culture show poor sporulation in WA. Key words: Foot rot, Media,

Abstract: Brucellosis is a
highly contagious and important zoonotic disease
worldwide and is endemic in India. Antibiotics are currently used in
treatment of Brucellosis. However, little information is available on the
antibiotic sensitivity of field isolates of Brucella
in different parts of India. We analyzed clinical samples (foetal stomach contents, foetal
membranes, uterine fluid, vaginal mucous and milk) from cattle and buffaloes
from Ludhiana for Brucella abortus organisms. Out of the total 104 samples
analyzed, 12 were positive for Brucella abortus by isolation. The isolates were confirmed to
be Brucella organisms by PCR. Morphological characterstics like smooth, glistening, translucent and
pinpoint colonies appearing after 3-5 days of incubation in microaerophilic environment were indicative of Brucella. The organisms were found to be positive
for catalase, oxidase and
urease. H2S was produced by 7 isolates.
All the 12 isolates were positive for nitrate reduction and were negative for
indole test. All the 12 isolates of Brucella abortus were
found to be positive by PCR using Brucella
specific primers B4/B5 and F4/R2 which revealed the desired amplicons of 223 bp and 905 bp, respectively. Isolated organisms were sensitive to chloramphenicol, oxytetracyclin,
ampicillin, streptomycin, gatifloxacin
and ceftaxime but resistant to penicillin, cotrimazole, cephalothin and
erythromycin. Keywords: Brucella

received higher crop attributes, yields, returns and quality of Indian
mustard but per cent of soil moisture, oil content, protein content and NPK
content had not affected by using of different antitranspirants.
The higher dose of nitrogen @ 80kg/ha at paired row spacing of 30 + 60 x 10cm
with application of combined spray of PMA+kaoline
at 45 and 90 days after sowing increased grain and stover
yields maximum economic returns and higher content and uptake of protein and
NPK in Indian mustard. Key words: Plant geometry,
nitrogen level, antitranspirants, oil content,
yield attributes water-use-efficiency, yield and economics. |
