Keywords: DNA probes, Diagnostics, Monoclonal antibodies
Abstract: Though monoclonal antibodies are more commonly used than DNA probes for detecting a variety of molecules, still the DNA probes have some advantages over monoclonal antibodies. The advantages being their sensitivity nature, requirement of less quantity of sample for analysis and the results are more easily computerized. This paper discusses the different target sites of probes and probe labels with the major emphasis on the probe synthesis. Further the chemical basis for the probe reaction and various diagnostic probe assays used in the clinical laboratory have been briefly discussed.

Keywords: Trichoderma viride, Fungicides, Herbicide, Compatibility
Abstract: An attempt made in the laboratory to understand the compatibility of Trichoderma viride with commonly used formulated fungicides based on Mancozeb 75% WP, Copper Oxy Chloride 88% WP (COC), Carbendazim 50% WP, Hexaconazole 5% EC, Propiconazole 25% EC and a herbicide, Metolachlor 50% EC, has revealed a significant variation in the effect of these chemicals on radial growth and inhibition of T.viride. The Mancozeb and Copper Oxy Chloride (COC) at the concentrations of 100 and 500 ppm do not inhibit growth of T.viride to any statistically significant level; however, at 1000 ppm Mancozeb and Copper Oxy Chloride (COC) did have an effect on growth of T.viride.Fungicides like Carbendazim, propiconazole, Hexaconazole and Metolachlor, irrespective of the concentrations, had a very significant effect on growth of T.viride, so as to exhibit a complete noticeable inhibition. The results indicate that the Mancozeb and Copper Oxy Chloride (COC) preparations are compatible to T.viride and hence, can be used together in the Integrated Disease Management towards the control of commonly occuring economically important plant root rot and wilt diseases.

Abstract: The application of micronutrients and Rhizobium japonicum inoculation showed significant response to seed germination (93%) grain yield (25g) and increase in biomass of soybean. Similarly, R. japonicum seed inoculation has also recorded grain yield. A combined treatment of micronutrients and R. japonicum inoculation proved to be better in increasing the grain yield and other agronomic and biochemical parameters. The result revealed the positive influence of micronutrients and Rhizobium inoculation both independently and in combination with increasing the seed germination and grain yield of soybean. Amongst all the treatments, combined treatment of micronutrients and Rhizobium inoculant proved to be the best to give the higher yield.

Abstract: The life cycle pattern of pink bollworm, Pectinophora gossypiella in relation to five different cultivars (TCHB, SUVIN, MCU7, LRA & MCU11) and five different age groups of squares and bolls (viz.10-20 day old squares, 6-15, 16-25, 26-35 & 36-45 day bolls) were also studied. Variations observed both in the immature and adult life stages did not differ significantly in all cases when comparisons were made between the cultivars within each age group, but differences were significant in most of the developmental parameters when observations were compared between the age groups within each cultivar. Similarly, the larval growth index (LGI) and total growth index (TGI) reveal very low value in the larvae and adult moths reared on cv. MCU7 compared to other cultivars, especially from V-age group bolls (36-45 days bolls). Significant influence of food regimes viz. effect of the cultivars of cotton and age of the squares and bolls, on larval, pupal and adult weight gain and fecundity rate were also observed in this study.

Keywords: Toxic pollutants, Contamination, Ground water
Abstract: Ground water, being an essential natural resource, has been assumed to be pristine in quality and must not be violated by contamination. Few of the ground water aquifers that supply drinking water are of ancient origin. Most of them are dynamic in nature and recharged repeatedly by water moving slowly or rapidly downward from the surface of the earth through the soil profile to a level that accumulates the water. In the process, Dissolved chemicals including pesticides can also be carried downward into the soil profile and eventually reach the ground water. The natural environment from where contamination extends can be viewed as consisting of several environmental zones extending form the atmosphere and the above - ground crop zone into the soil from the surface down, through the root zone, the unsaturated soil, eventually down to the saturated zone where ground water is situated. The contaminants from the above zones passes through different zones get transformed into various degraded products and enter the ground water and create pollution. Therefore, it is essential to have a detailed knowledge on the sources of ground water pollution namely sewage and other wastes, industrial eflluents, agricultural discharges and industrial wastes, their influence on soil properties and measures to be taken for the abatement of toxic pollutants, these details are discussed in this paper.

Abstract: Phosphate-solubilizing microorganisms and Rhizobium sp. were isolated from the rhizosphere of leguminous plants. Aspergillus sp. and Bacillus sp. were more prevalent, contributing the most common and widely distributed microbes in the rhizosphere soil. In a plate assay the solubilization efficiency (E) was more in Bacillus sp. GYM 4 (77%), COP 1 (75%) and TEP1 (70%). In the in vitro phosphate solubilization activity Bacillus sp. ARH 3 was the best solubilizer of RP (66.0 ?g/ml). A decrease in pH of the liquid medium was accompanied by phosphate solubilization. All the physical parameters of the cowpea plant on 30th day were significantly higher in triple inoculation treatment (T7 ).

Abstract: Field investigations were carried out to study the efficiency of phophorus and iron (0, 50, 75 & 100% of recommendation ) enriched composts (sugarcane waste compost, sugarcane waste & sewage sludge (2:1) compost) on sugarcane. The results showed that though 100 percent phophorus and iron enriched compost @ 750 kg ha-1 registered the highest cane yield (116.7 t ha-1), as well as sugar yield (14.55 t ha-1) and it could not surpass the yield obtained at 75 percent recommended phosphorus and iron enrichment level (114.4 t ha-1 & 14.14 t ha-1). The quality parameters of sugarcane viz., brix, sucrose, commercial cane sugar (CCS) percent and reducing sugar content have also recorded on par values with that of 100 percent phophorus and iron enrichment level. Hence, it is obvious that 25% of recommended phosphorus and iron may safely be curtailed from the fertilizer schedule of sugarcane if the above nutrients are supplied as enriched compost.
