These on examination gave Alternaria tenuissima (Kunze ex Pers.) Wiltshire, a pathogen causing leaf spot disease, not reported earlier on this host from India. The spot were spherical to irregular, not exceeding 0.5 cm square of the leaf on ventral surface. These were light to dark brown. The disease starts as a small pin head sized light brown spot both on the older and younger leaves. Extensions occur with...

Patsan stem sticks, A promising substrate for cultivation of Pleurotus sajor-caju (Fr.) Sing.
Patsan stem sticks were used as the substrate for the cultivation of Pleurotus sajor-caju during beginning of January to middle February in 1990. The sterilization of water soaked of one foot long bare patsan stem stocks was done at 60-70°C for one and half hours and these were spread over the sterilized cemented floor for one hour to drain off excess of adhered water. The sowing was done in polythene bags (60X45 cm) with freshly prepared spawn on the boiled wheat grain in inter-spaces of the stem sticks and in this way one...

Comparison of Growth and Development of Pleurotus florida against Wastes from Animal Origin
The mushroom produces extra cellular enzymes which helps for hydrolysing the complex organic substances into simpler forms that can be utilized and assimilated by them or release in surroundings. Generally they utilized the substrates from plant origin i.e. lignocellulosic materials which comprises of three major groups of polymers i.e. cellulose, hemicelluloses and lignin [1] which represent the most abundant renewable organic matter on the earth. These substrates are used as a growing medium for oyster mushroom. It includes cereal wastes [2], millet wastes [3], Oil crop wastes [4], Cotton wastes [5], palm wastes...
