He scanned up the row, looking for more infected spinach plants. His grandfather's method of defense against vCaMV was to change up the varieties throughout the rows, planting no two plants of the same variety within ten feet of each other, which made for jagged, uneven growth and shaggy rows. Had the method broken down here? Stark could see the Bloomsdale spinaches, the Olympia, the Sailorman, de Wilde Savoy, and the Oklahoma Green, alternating through the rows.
