A large amount of agro-waste is produced annually world over. Agricultural straw consists mainly of cellulose, hemicellulose and lignin, the most abundant renewable biopolymer. Much of this material is disposed of by burning, which results in environmental pollution; only a little is used as a feed for ruminants. The use of fungi for conversion of lignocellulosic waste into food and feed rich in protein have gained importance as an alternative for developing unconventional source of proteins. Species of Pleurotus (oyster mushroom) represents the second largest variety of the mushroom in the...

Parthenium hysterophorus has become a major weed of various areas of the country in a relatively short time. In the present study the detailed survey of district Sialkot with total 53 sites was conducted to evaluate the extent of infestation of Parthenium hysterophorus. Along with P. hysterophorus a great number of other weeds were also observed during the survey. Among the waste lands of Sialkot infestation of P. hysterophorus was more than 50%, along the road side was 60%, the waterways 46% and along the crop fields was 56% and at the banks of rice fields and Trifolium sp. and in fallow...

In this study the role of epicuticular wax in transmission of CLCuV has been studied. Epicuticular waxes plays very important role in hindering the attachment of insects to the leaves. In this study the wax deficient mutant plants GaWM3 were used as experimental plants while Gossypium arboreum (786) were used as negatively controlled plants as it is reported that whitefly can not transmit virus in it and G. hirsutum (MNH-93) were taken as negative and positive control plants because it has severe viral attack in past. It is important to mention here that GaWM3 were produced in our laboratory...
