The effects of raw material particles size, types of solvents and solvent-to-solid ratio on the yield of rotenone extracted from derris elliptica roots

Currently, bio-pesticide is relatively harmless to human and environment and thus desirable for its use in the control of insect vectors. Bio-pesticide has been increasingly important in both scale commercial agriculture and small plot, subsistence farming. One of the sources for bio-pesticide is ‘t...
