Soil microorganisms such as Trichoderma asperellum and Gliocladium sp have the potential to become biological control agents in inhibiting the growth of fungi Botryodiplodia theobrome which causes stem rot disease in citrus plants. The purpose of this study was to determine the potential of T.asperellum and Gliocladium sp fungi in inhibiting the growth of B. theobrome fungus causing stem end rot disease in citrus plants. The antagonistic test was carried out using the dual culture method using PDA media; observations were made on the growth of pathogenic fungi and antagonistic fungi to measure their inhibitory power. The results of the observation and calculation of the fungal growth rate were analyzed using the T test with a level of 5%. The pathogen fungal growth rate in the antagonistic test was slower than control and inhibition of B. theobrome by T.asperellum and Gliocladium sp were respectively at 78.67% and 84.56%. The mechanism of the two antagonistic fungi has the nature of competition and parasitism because of the broader inhibition spectrum than the pathogenic fungi. Keywords: Botryodiplodia theobromae, Trichoderma asperellum, Gliocladium sp, antagonistic test.

Background: Clusterbean is an important legume crop in arid and semi-arid regions of Rajasthan. It provides livelihood security to arid zone farmers. Bacterial leaf blight (BLB) and root rot are two important diseases of clusterbean which limits its production and productivity. Although, management of these diseases are possible through fungicides. However, in present study focus on use of bio-agents which are friendly to the environment.Methods: Field experiment was conducted at ARS, SKRAU, Bikaner, Rajasthan during three consecutive kharif seasons of 2017 to 2019. The experiment was conducted on cv. RGC-1033 with six different combination of Trichoderma harzianum and Pseudomonas fluorescens bio- agents viz, seed treatment, soil treatment and their combinations against the root rot disease and compared with an untreated control.Conclusion: Seed treatment with a combination of T. harzianum + P. fluorescens (4+4 g/kg seed) along with soil application of T. harzianum + P. fluorescens (1.25 +1.25 kg in 50 kg FYM for each/ha) was an effective treatment which reduced root rot incidence and increased seed yield under field conditions. It can be recommended to the cultivators of clusterbean for enhancing yield.

Hater resource managers in semi-arid regions are faced with some unique problems. The wide variations in precipitation and stream flows in semi-arid regions increase man's dependence on the ground water resource for an ample and reliable supply of water. Proper management of the ground water resource is absolutely essential to the economic well being of semi-arid regions. Historians have discovered the remains of vanished advanced civilizations based on irrigated agriculture which were ignorant of the importance of proper ground water resource management. In the United States a great deal of effort is presently being expended in the study and control of toxic discharges to the ground water resource. What many public policy makers fail to understand is that the potential loss to society resulting from the mineralization of the ground water resource is potentially much greater than the loss caused by toxic wastes discharges, particularly in developing countries. Appropriations for ground water resource management studies in developed countries such as the United States are presently much less than those for toxic wastes management and should be increased. It is the reponsibility of the water resource professional to emphasize to public policy makers the importance of ground water resource management. Applications of ground water resource management models in the semi-arid Central Valley of California are presented. The results demonstrate the need for proper ground water resource management practices in semi-arid regions and the use of ground water management models as a valuable tool for the water resource manager.
