INTEGRATED DISEASE MANAGEMENT (IDM) Lecture 11 INTEGRATED DISEASE MANAGEMENT (IDM)

What is IDM? Integrated disease management is the practice of using a range of measures to prevent and manage diseases in crops. Hazard analysis is used to identify the potential for infection so that preventative or curative measures can be put in place to minimise the risk of disease infection and spread.

IDM & IPM Familiar with IDM? No you are familiar with IPM. IPM: Integrated Pest management is a common practice used in many farms all over the world. Refers to the integration of best available practices that can minimize or eradicated the population of pests in any farm.

Examples of IPM Biological Control Physical Control Mechanical Control Cultural Control Chemical Control Quarantine measures

Components of IDM Exclusion — Eradication — Protection – Resistance — Therapy – Avoidance –

Exclusion Keep pathogens (things that cause disease), vectors (things that spread disease) and infected plants out of disease-free areas. For example:Reduce the introduction of inoculum from external sources during the course of the epidemic or delay the introduction of inoculum from external sources by means of plant quarantine

Eradication Destroy a disease organism after it has become established. You can do this by destruction of infected plants, disinfection of storage bins, containers and equipment, and/or soil disinfection by fumigation, pasteurization, solarization or drenching.

Protection Use a physical barrier such as a row cover. You can also use chemical applications available to prevent a disease from becoming established.

Resistance The planting of resistant varieties. Plant breeding is an important component which can be used to obtain more resistant varieties.

The use of chemicals that are systemic in the plant. Therapy The use of chemicals that are systemic in the plant.

Avoidance Use good cultural practices such as planting date selection, seedbed preparation and water management to avoid disease. Poorly drained soils, shade and other factors can increase the susceptibility of plants to disease.  Provide adequate irrigation, fertilization and space for each plant. Handle plants carefully to prevent injury, as the injury may later be the access point for a disease.
