To avoid the incidence of diseases in propagating a good fresh clean seed or cutting and good products are primordial. Be particular about the medium in which the seeds will be germinated or cuttings will be grown. This, together with careful attention and a clean environment should ensure weed seeds, insects, or disease microorganisms are essentially eliminated.

Note: There is no genetic diversity among plants propagated from cuttings. Therefore whereby any desirable traits are luckily preserved, any faults such as susceptibility to disease are faithfully reproduced too. So be sure to take cutting from strong healthy plants to give yourself the best chance of success.
