Abstract

The purpose of this research is to find the effectiveness of bandotan’s (Ageratum conyzoides L.) leaf extract towards mortality of Boophilus microplus in vitro and also to identify of lethal concentration and lethal time. This research used 125 Boophilus microplus. This research used five treatments. The observation of mortality was done every six hours. Boophilus microplus dies when there is no movement. The data were analyzed using one way ANOVA and followed by Duncan's Multiple Distance Test. The result are said to be significant if p<0.05. Probit analysis of LC50 is 1.63% at the first hour, 0.85% at the second hour, 0.54% at the third hour, 0.34% at the fourth hour, 0.04% at the fifth hour and 0.04% at the sixth hour, LC90 reached by using 5.6%, 2.9%, 1.8%, 1.2%, 0.16 and 0.16% concentration in 1, 2, 3, 4, 5 and 6 hours. The LT50 of ethanol 1% (K-) is at 10.142 hours, neguvon suspensionon (K+) is at 0.747 hours, 1% concentration (P1) is at 2.184 hours, 2% concentration (P2) is at 1.579 hours, 3% concentration (P3) is at 0.923 hours and LT90 is at 23.734, 1.749, 5.110, 3.695 and 2.159 hours. The conclusion of this study was bandotan’s (Ageratum conyzoides L.) leaf extract was effective as an acaricide based on the mortality of Boophilus microplus.
