| 1. | The sclerotia structure acts as the primary inoculum in affected fields.
|
| 2. | These cells then overwinter and serve as inoculum the following spring.
|
| 3. | Disease inoculum is reduced by long rotations with nonhost crops.
|
| 4. | A plastic spreader is also used to spread the inoculum evenly.
|
| 5. | This results in the decline of the egg inoculum in the soil.
|
| 6. | General sanitation practices have also reduced the spread of inoculum.
|
| 7. | The oospores are the main source of the primary inoculum of this disease.
|
| 8. | Bacteria present in plant debris can serve as a source of secondary inoculum.
|
| 9. | Hence, the presence of these plants may increase the supply of inoculum.
|
| 10. | Conidia produced during spring and summer are the major source for primary inoculum.
