    Abstract: Coal mill reject can be considered as of the waste materials which can be used in construction industry as the substitute of coarse aggregates. Everyday thermal production many thousand tonnes of coal mill reject are generated. This reject is currently not used widely and used only in land filling, rail road ballast material etc, which are not very high value added application. These applications utilize only about 5% to 10% of coal reject generated and remaining material is dumped as a waste. In order to reduce the accumulation of coal mill reject and also to provide an alternative material for coarse aggregate in concrete , an approach has been done to investigate the properties of coal mill reject for replacing coarse aggregate in concrete. This invention was performed to generate specific experimental data on the potential use of coal mill reject as coarse aggregate replacement in concrete. This research work mainly consists of eight main tests on the proposed aggregate and concrete made of this material. The various tests are conducted for showing the behavior of coal mill reject as compared to normal aggregate. i) Sieve Analysis ii) Fineness Test iii) Bulk Density Test iv) Flakiness and Elongation Test v) Water Absorption Test vi) Crushing Strength Test vii) Abrasion Test viii) Compressive Strength Test

    Abstract: The present invention deals with a mycoherbicidal isolate of Setosphaeria monoceras sp. or extracts obtained therefrom, useful for the control of Water hyacinth. The present invention also discloses biological control compositions comprising fungal isolate extract formulated in a growth medium for maintaining the viability of extract when the biological control composition is applied to weed. The present invention also discloses methods of screening fungal isolate to determine if they exhibit biocontrol activity. The present invention also discloses use of Setosphaeria monoceras strain. In yet a further aspect the invention relates to use of an Setosphaeria strain for producing a herbicidal agent effective for controlling growth of water hyacinth plants. The strain used preferably is a strain having the characterizing features of Setosphaeria strain AGWH#1 1 as deposited at IMTECH under accession number MTCC 5974. The present invention to provide the 18s rRNA sequence analysis showed 96% nucleotide similarity of the Fungi to Setosphaeria monoceras. (AGBIO designated AGWH#1 1/NCIM1370/MTCC 5974) but also indicated nucleotide variation of this fungus from other known genus of Bipolaris, Pleosporaceae, Cochiliobolus, Alternaria including an environmentally acceptable alternative to synthetic chemical herbicides for the control of weeds, such as Water hyacinth. The present invention also discloses methods of whole genome study of strain.

    Abstract: The invention relates to describe host-specific extracellular phytotoxins produced by Fusarium sp. That has a phytotoxic to Lantana camara. A novel method using phytotoxin has been developed for controlling Lantana camara, these phytotoxin can be used partially pure, as a cell- and spore-free filtrate, a crude filtrate, or a crude suspension of the culture and optionally along with other additives. 18s rRNAsequence analysis showed 93% nucleotide similarity of the Fungi to Fusarium sp. But also indicated nucleotide variation of this fungus from other known genus of Nectaria, Mariannaea, Volutella, Myrothecium. This analysis suggested that the novel fungus is closest to Fusarium sp. It is proposed that this is a new species of Fusarium sp.
