Morphological and cultural characterization of Phyllosticta zingiberi (Ramkr.) causing leaf spot disease of ginger
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 3
Abstract
Isolation of ginger (Zingiber officinale) leaf spot pathogen form the UBKV farm field was done in the laboratory. The isolated pathogen was identified as Phyllosticta zingiberi on the basis of morphological characters as documented in taxonomic keys. The microscopic observation revealed that the pycnidia were globose to subglobose with dark brown colour measuring 124.16 μm × 2.35 μm in average. The pycnidio spores were hyaline, oval to bullet shaped, monoguttulate measuring 4.02 μm × 2.35 μm in average. Among the different media tested for growth highest growth was recorded in Oat meal agar (26.44 cm2) followed by malt extract agar (24.04 cm2) which was statistically at par. The temperature of 25˚C favoured maximum growth (24.20 cm2). However, higher sporulation was observed in 30˚C. Among the different carbon source tested, mannitol supported the highest growth of the pathogen (27.67 cm2).

Effect of nitrogen and potash on Early shoot borer (Chilo infuscatellus Snellen) incidence in differently maturing varieties of sugarcane
It has been argued that fertilization may influence the susceptibility of insect pests, and thus, can increase the crop production by lowering the incidence of insect-pest. Here, the present investigation was carried out...
Influence of soil surface manipulation on soil temperature in relation to peanut production
Soil temperature is recognised as one of the most important factors in crop production. Some degree of manual control of soil temperature is possible through regulation of soil surface cover. The effect of eight mulch tr...

Increase in wheat production through management of abiotic stresses : A review
About 9% of area on earth is under crops out of which 91% is under various stresses. On an average, about 50% yield losses are due to abiotic stresses mostly due to high temperature (20%), low temperature (7%), salinity...
