                        1. soil fungus attacks stem base

                                1. increases level of inoculum
                          3. Pests
                            1. Slugs

                                1. GOOD
                                  1. cannot differentiate between soil and crop in autumn hence reduces summer infection
                                    1. A straw cover can also lower infection
