Definition
Integrated disease management is the practice of using a range of measures to prevent and manage diseases in crops.
Principles of Plant Disease Control
1. Exclusion
Exclusion means preventing the entrance and establishment of pathogens in uninfested crops in a particular area
2. Eradication
Eradication involves the elimination of a pathogen once it has become established on a plant or in a field
3. Protection
Protection is the use of some protective barrier between the susceptible part of the suspect or host and the pathogen
4. Resistance
Disease-resistant and tolerant varieties are the cheapest, easiest, and most efficient way to reduce disease losses
5. Therapy
Therapy is used on individual plants and can't be used on a large scale
6. Avoidance
Control of insect vectors and weed hosts: certain insects, especially aphids, beetles and leafhoppers, are known to transmit viruses and mycoplasmas from infected plants to healthy plants
