Among the evaluated different doses and combinations of cow urine and botanicals, cow urine 100% + neem oil 2% was found highly effective against blackfly and psylla in acid lime. Cow urine 70% + neem oil 2% was the second best effective. However, cow urine 100%, cow urine 50% + neem oil 2% and cow urine 70% were also found equally effective followed by cow urine 50%, cow urine 30% + neem oil 2% and cow urine 30% found least effective in reducing insect pests population during present investigation.
