21. An inoculum of the fungus was developed. 22. Planting infected seed potatoes can also be a source of inoculum to a new field. 23. The amount of asexual reproduction that occurs during the winter affects the spring inoculum levels. 24. Both primary and secondary inoculum are spread by the splashing of rain on to new tissue. 25. This serves as the primary inoculum . 26. During the fermentation process, inoculum is added to the batch to speed the rate of fermentation. 27. As an oomycete, " P . halstedii " releases motile zoospores as secondary inoculum . 28. Sanitation can also be important to reduce the spread of inoculum and clean seed should be planted. 29. As noted earlier, epidemic development heavily depend on successful dispersal of conidia produced from primary inoculum . 30. Conversely, the dispersal of inoculum via rain is considered an effective mechanism in spreading the inoculum.
