Seeding by mid-August is preferable to seedings in late August or September, because this gives plants more time to develop some natural resistance. Of course, spray seedings have very little risk of the disease. I don't recommend plowing as a disease control practice, since soil conservation is important to us and future generations. History of adjacent fields . Even if SCSR has not been observed in the field being sown, the field may still be at risk if the disease has been detected in adjacent fields.
Adjacent fields can be a source of airborne spores for the newly seeded fields.
Also, the detection of SCSR in adjacent fields suggest that local conditions have allowed SCSR outbreaks in the past and may allow them in the future. Let's assume, for example, you are going to seed a 2-acre field surrounded by pasture. The field has been planted to tobacco for the past 10 years, and was plowed and disked to create a good seedbed. Keep in mind that this is an airborne fungus. The pasture surrounding the field could easily provide enough inoculum to cause a serious outbreak.
