The herbal based acaricide used as biocontrol agent for protecting environment particularly hilly area. As per indigenous technical knowledge records, the Nicotiana tabacum was a traditional control remedy for control of ectoparasites in India. In vitro acaricidal efficacy of crude aqueous leaf extract of Nicotiana tabacum along with neem and turmeric followed by Annona leaves on immature and adult stages of Rhipicephalus sp. was carried out at different concentrations of with different time interval. These extract combo had a significant effect on the mortality of nymphal and adult stages of ticks. The 70%, 80% and 90% mortality of Nymphal and adult stages of ticks at 24-36 hours post treatment with 40%, 50% 70% concentration of herbal extract in invitro assay. The mortality rates of ticks increased with the increasing the extract concentrations both in vivo and in vitro. Nicotiana tabacum causes paralysis of ticks and leads to detachment from the body of animal and concluded that Nicotiana tabacum along with turmeric and annona extract is effective biocontrol agent for controlling ectoparasites without any environmental pollution and harmful side effect in animal health.
