| Abstract: | Abstract A protocol for biological control of weeds is described. It consists of preintroductory studies on the distribution and ecology of the weed, the discovery of organisms adapted to it, the estimation of their effectiveness, the selection of the most damaging strain and the examination of their safety as biological control agents and post-introductory studies to obtain establishment of non-infected stocks and to observe their effect on the weed populations. Recent biological control studies on weeds are shown to support the proposals and the biological basis underlying the proposals is discussed. It is shown that where these have been ignored biological control has not been successful whereas when the protocol has been fully applied the weed has been successfully controlled. |
