The OSU Plant Clinic can help you diagnose the problem while the PNW Plant Disease Management Handbook can help with solutions. disease management? This review focusses on how biocontrol microbes modulate plant defense mechanisms, deploy biocontrol actions in plants and offer new strategies to control plant pathogens. 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. Good Agricultural Practice, or GAP, is a term used to define the conditions under which a plant protection product should be used. New strains of an organism may develop that will attack resistant varieties or become tolerant to certain pesticides when these practices are used alone. By focusing on natural processes, growers use pest control methods beginning with the least toxic and amplifying the pest control needs gradually if problems persist.

Postharvest Disease Management Any postharvest decay management program needs to begin with preharvest practices that promote a healthy crop, reduce conducive environments for pathogen infection and disease development, and minimize the amount of the pathogen that may infect or contaminate the crop before harvest. Plant quarantine and its role in pest control. BACKGROUND. Mechanical Control - A Case Study Rotation - nonhost plants and resistant varieties; reduce soilborne pathogen populations Trap plants & antagonistic plants - e.g. Grow plants under optimum conditions and there will be fewer disease problems. Apart from simply applying individual biocontrol microbes, there are now efforts to improve, facilitate and maintain long-term plant colonization. 1. The disease can cause a complete loss of gladiolus crops in the absence of fungicides and is considered a quarantine pest; early detection and destruction of the pathogen are important in management of gladiolus rust. This review focusses on how biocontrol microbes modulate plant defense mechanisms, deploy biocontrol actions in plants and offer new strategies to control plant pathogens. Bio. Crop plants can be pests (weeds) if present where they are not wanted, for example, volunteer alfalfa in corn, corn in soybeans, or rye in wheat. Verma, B.R. Avoid working fields when plants are wet. • Exclusion of pathogens. 5.2. A successful disease control program depends on a crop production system, which closely aligns with the goals of pest management. Naturally occurring plants possess several antimicrobial metabolites having less human adversities and environmental impact. Oral diseases are major health problems with dental caries and periodontal diseases among the most prevalent, preventable global infectious diseases. Remove infected plants or plant parts. Achieving sustainable plant disease management through evolutionary principles. winter), could also be stressful to the plant, and the plant is less likely to mount defensive reactions to fend off infection.

Since then various bio- control products have been found to be very effective in controlling the plant disease. Reduce the level of disease by selecting a season or a site where the amount of inoculum is low or where the environment is unfavorable for infection.
