Why is plant disease management important?
Many plant diseases cause less dramatic losses annually throughout the world but collectively constitute sizable losses to farmers and can reduce the aesthetic values of landscape plants and home gardens. The goal of plant disease management is to reduce the economic and aesthetic damage caused by plant diseases.
What is integrated disease management in plants?
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.
What is Principles of IDM?
The six fundamental principles of disease management are exclusion, eradication, protection, resistance, therapy, and avoidance of insect vectors and weed hosts.
What is most important in disease management in plants?
Practices such as planting date selection, seedbed preparation and water management are cultural practices that help avoid disease. Poorly drained soils, shade and other factors can increase the susceptibility of plants to disease. Place plants properly or remove and replace problem plants with better-adapted species.
What is the importance of plant disease diagnosis in pest management?
Therefore, diagnosis is one of the most important aspects of a plant pathologist’s training. Without proper identification of the disease and the disease-causing agent, disease control measures can be a waste of time and money and can lead to further plant losses. Proper disease diagnosis is therefore vital.
What is Integrated Crop disease Control?
Rather than relying on a single method of pest control, IPM combines pest-resistant cultivars, fertilizer management, agronomic practices that conserve and increase the effects of predators and other naturally occurring biological control agents, and, when needed, prudent use of pesticides based on need rather than …
What is the best principle and method of plant disease control?
Traditional Principles of Plant Disease Control. 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. Exclusion—prevent the introduction of inoculum. Eradication—eliminate, destroy, or inactivate the inoculum.
Why integrated disease management IDM is considered most useful for control of plant diseases?
Promotes sound structures and healthy plants. Promotes sustainable bio-based disease management alternatives. Reduces the environmental risk associated with management by encouraging the adoption of more ecologically benign control tactics. Reduces the potential for air and ground water contamination.
What is the importance of plant disease diagnosis?
What is the best method of controlling plant diseases?
Use Resistant Varieties Using resistant varieties is the most efficient way of controlling vegetable diseases. Make an effort to buy resistant varieties when they are available. Seed catalogs generally list resistant traits of the various vegetable varieties.
What are the main goals of Integrated Disease Management?
Integrated disease management (IDM) systems are being developed with their main goals to: 1 (1) Eliminate or reduce the initial inoculum, 2 (2) Reduce the effectiveness of initial inoculum, 3 (3) Increase the resistance of the host, 4 (4) Delay the onset of disease, and 5 (5) Slow the secondary cycles of the disease.
What do you need to know about integrated pest management?
What is Integrated Pest Management (IPM)? Integrated Pest Management (IPM) is an ecosystem-based strategy that focuses on long-term prevention of pests or their damage through a combination of techniques such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties.
What does IDM stand for in disease management?
Integrated disease management (IDM) is a disease control approach that uses all available management strategies to maintain disease pressures below an economic injury threshold.
Why is host resistance important in integrated disease management?
In the integrated disease management program, concentration on development of host resistance, apart from other management practices directed at containing diseases, forms an important component of the overall disease-management approach.
