The last cultural control method would be to maintain clean fields once infected. Keep the field well managed, do not allow overgrowth of weeds or plants near the grapes. Once the plants have been infected “Remove all mummies from the canopy during the dormant pruning process. Mummies produce spores next to the susceptible grapevine tissues throughout the season; even relatively few can cause significant damage.” Another technique to rid of infection can be to “cultivate the vineyard before bud-break to bury the mummified berries. Diseased berries covered with soil do not produce spores that will reach the developing vines”.
