New strains of an organism may develop that will attack resistant varieties or become tolerant to certain pesticides when these practices are used alone. 155-173. A successful disease control program depends on a crop production system, which closely aligns with the goals of pest management. The usefulness of certain measures depends on the specific crop-pathogen combination. 2. Introduction. 1-5. Integrated disease management in organic farming combines the use of various measures. 1. Integration of BCAs with other disease management tools often provides broader crop adaptation and both more efficacious and consistent levels of disease control. In organic disease control, natural materials (things found in nature or that exist in the environment) can be used to inhibit or prevent the activity of plant pathogens. 1974. Introduction. Chemicals used to control bacteria (bactericides), fungi (fungicides), and nematodes (nematicides) may be applied to seeds, foliage, flowers, fruit, or soil. Avoidance—prevent disease by selecting a time of the year or a site where there is no inoculum or where the environment is not favorable for infection. Instead of plant disease control, we need to think in terms of plant disease management. A second shortcoming is that the traditional principles of plant disease control do not take into consideration the dynamics of plant disease, that is, the changes in the incidence and severity of disease in time and space. Best Practices. ii) Exclusion: Quarantine, inspection & certification, seed treatment. A good disinfectant is 10% Clorox or bleach (10 ml household bleach to 90 ml water).
