About Lesson
Management:
- It conveys a concept of continuous process which is based not only on the principle of eradication of the pathogen but mainly on the principle of minimizing the damage or loss below economic injury level.
Importance:
- Measures taken to prevent the incidence of the disease, reduce the amount of inoculum that initiates and spreads the disease and finally minimize the loss caused by the disease are called as management practices.
Essential considerations in plant disease Management:
- Benefit-cost ratio
- Procedures for disease control should fit into general schedule of operations of crop production
- Control measures should be adopted on a co-operative basis over large adjoining areas. This reduces frequency of applications, cost of control and increases chances of success of control measures
- Knowledge aspects of disease development is essential for effective economical control. Information is needed on the following aspects
- Cause of a disease
- Mode of survival and dissemination of the pathogen
- Host parasite relationship.
- Effect of environment on pathogenesis in the plant or spread in plant population.
- Prevention of disease depends on management of primary inoculum.
- Integration of different approaches of disease management is always recommended.
