| Sumario: | <span>One option to lessen the <span>problems arising from the use of synthetic insecticides is to exploit plants <span>that have insecticidal activities, such as species of <em>Calophyllum</em><br /><span>(Clusiaceae). The study has been conducted to prepare insecticidal <span>formulation from <em>C. soulattri</em> bark extract and to evaluate their residual <span>activity against<em> C. pavonana</em>. Formulation prepared by using emulsifier, <span>solvent, and sticking agent. Colour, acidity and emulsion stability were <span>recorded as physic-chemical character of formulation. The result showed <span>that the formulation of <em>C. soulattri</em> bark extract was stable, and their pH was <span>normal. Bioassay of residual activity was done using leaf-residual method. <span>Formulation of bark extract of 66 EC sprayed in suspension concentration of <span>1% on potted broccoli plant had residual activity around 70.7%-72% with <span>range of half-lives of 9.4-9.6 days.</span></span></span></span></span></span></span></span></span></span></span></span><br /></span> |
