Abstract: The present research work is arrived to nullify pathogenicity of V. harveyi on P. monodon through medicinal plants, a healthy, eco-friendly traditional method. The pathogenicity of V. harveyi causes entirely loss in the shrimp culture farms and the use of commercial anti-biotics for disease control causes are highly toxic, side effects to the environment and consumers. Hence the herbal extracts of Neem leaf and Turmeric rhizome were tested to nullify the effect of pathogen, along with the commercial antibiotics like ciprofloxacin, Amoxicillin, Tetracycline and Ampicillin to compare the effect on V. harveyi. The methanolic extracts of plants and antibiotics were examined through well diffusion method and MIC also studied. Curcuma and ciprofloxacin exhibited high anti vibrio activity. The study revealed that the rhizome extract of curcuma is the best herbal product for reducing the effect of opportunistic pathogen V. harveyi which is abundant in gastro-intestinal tract of shrimp and causing a great loss to the aqua farms.
