Abstract: The study was carried out to determine the Effect of Concentrations of Vestaline®(Pendimethalin) herbicide on Growth Performance of Clarias gariepinus juveniles. The toxicity test was carried out using 180 healthy fish of mean weight 27.97±0.03g which were divided into six treatments with each treatment having ten fish and the setup was in triplicate. The fish were exposed to 0mg/l (control), 1.89mg/l, 3.79mg/l, 5.68mg/l, 7.57mg/l and 9.46mg/l) concentrations of Vestaline®(Pendimethalin) herbicide for eight weeks during which the fish were fed at 3% of their body weight twice daily and weights measured weekly. Data obtained were subjected to analysis of variance (ANOVA) at P<0.05using Minitab. The results showed retard growth as compared to the control. Growth parameters such as Specific Growth Rate and Food Conversion Efficiency decreased (P<0.05) with increase in concentrations. Poor Food conversion Ratio and poor percentage weight gain were also recorded. Vestaline®(Pendimethalin) herbicide from the study had negative influence on Clarias gariepinus weights and ability to utilize feed.

Abstract: Agriculture have a significant portion of the economies of world and therefore can contribute toward major continental priorities such as eradicating poverty, hunger, rapid industrialization, economic diversification, sustainable resource utilization, investments, and environmental management. Plant-associated microbiomes have tremendous potential to improve plant resilience and yields in farming systems. There is increasing evidence that biological technologies that use microbes or their metabolites can enhance nutrient uptake and yield, control pests and mitigate plant stress responses. Microbiological achievements of recent years have emerged as powerful tool to improve quality attributes of sustainable agriculture and environmental health. The chemical fertilizers used in the agriculture to increase yields but kill microflora, pests, and weeds, it have a big harmful impact on the ecosystem. Because of current public concerns about the side effects of agrochemicals, there is an increasing interest in improving the understanding of cooperative activities among plants and rhizosphere microbial populations. The review deals with microbes in biotechnology and their diversified applications in agriculture as bio-fertilizers, bio-pesticides, bio-herbicides, bio-insecticides, fungal based bio-insecticides and viral based bio-insecticides. Finally, a brief highlight has been given on the role of microbiology on development of sustainable agriculture and environment friendly approach to increase crop production and environmental health.
