Abstract
The experiment was carried out to study the efficacy of various organic
compound viz., Neem leaf extract 5 %, cow urine 10%, Datura
leaf powder, Lantana leaf extract 5%, Ipomoea leaf extract 5%,
eucalyptus leaf powder and cow dung ash against aphid infesting groundnut. All
treatments were found significantly superior over control. The neem leaf
extract 5% was ranked on top having mean population of aphids i.e. 1.74 and
suppressing the maximum insect population. The trend of efficacy of different
treatments against tested insect pests in descending order are neem leaf
extract 5% > cow urine 10% > Datura leaf powder> Lantana
leaf extract 5% > Ipomoea leaf extract 5% > eucalyptus leaf powder
> cow dung ash. Treatment eucalyptus leaf powder in which 4.17 aphids was
observed and that was also at par with cow dung ash having 4.39 population of
aphids. All the treatments proved statistically superior over control in which
highest aphids population i.e. 7.88 were recorded. The highest net profit (₹
50377.00 and 49216.00/ha) was obtained from the neem leaf extract 5% for
both the years i.e. 2018 and 2019, respectively, while the lowest net profit
(₹16406.00 and 16405.00/ha for both the years, respectively) was estimated from
the treatment of cow dung ash. By working out the BC Ratio it was found that
the neem leaf extract 5% ranked 1st with highest BC i.e.
1:20.35 and 1:19.88 for both the years, respectively, and minimum in cow dung
ash i.e. 1:6.98 which was quite similar for both the years.
