"No, but we can control the microclimate of the field," Elias said, a spark of his old academic fervor returning. "Look here, page 415. Spore germination requires a specific leaf wetness duration and temperature range. If we disrupt the humidity at the canopy level, we stop the spores from firing their infection pegs."
"Professor, English please," Maya said, not taking her eyes off the treeline. "We need to know how to kill it before it kills our dinner." Plant Pathology, Fifth Edition
"We need to understand the infection court," Elias muttered to his apprentice, a quick-witted young woman named Maya who was currently scanning the perimeter for rival scavenger bands. "No, but we can control the microclimate of
Elias walked out into the center of the field and knelt down. He pulled a magnifying loupe from his pocket and examined a leaf blade. There were spores on the surface, visible as tiny specks of dust, but they were dormant. Desiccated. The chain of infection had been broken. The microclimate manipulation had worked. If we disrupt the humidity at the canopy
Elias formulated a desperate plan based on the principles of integrated pest management detailed in the textbook. They couldn't spray chemicals they didn't have. Instead, they would use physics and traditional cultural practices to manipulate the disease triangle.
The "Super-Blast" had swept through the Midwest three months prior. It ignored conventional fungicides, bypassed genetic resistance, and turned amber waves of grain into gray, fuzzy mush within forty-eight hours. Elias, a former professor reduced to a scavenger of the soil, knew they were running out of time. The settlement at Ironwood depended on this valley’s emergency crop. If the blight took the wheat, the winter would take the people.
