Integrated plant disease management (IPDM)

Component of IPDM

• Cultural practices
• Regulatory measures ( Quarantine)
• Chemical methods
• Biological methods
• Genetic engineering

Rice disease and IPDM

1. Fungal disease
2. Blast : Foliar disease and pathogen survive on collateral host
3. Brown spot of rice: Seed borne and a foliar disease.
4. Sheath rot, sheath blight, foot rot and stem rot: Soil borne disease
5. False smut: Seed borne disease

Control

• Foliar spray of carbendazim @ 0.1% or tricyclazone @ 0.06% for blast.
• Foliar spray of validamycin for sheath blight and sheath rot.
• Carbofuran granules decrease viral disease.

Sugarcane disease and IPDM

1. Red rot: Sett borne disease and spreads through irrigation water.
2. Whip smut: Sett borne and spreads through wind borne sporidia.
3. Pine apple disease, sett rot: Sett borne disease.
4. Grassy shoot: Vector borne phytoplasmal disease.
5. Ratton stunting: Sett borne ( Clavibactor xyli).
6. Sugarcane mosaic: Survives on weeds and disseminated by insects vectors.

Control

• Hot water treatment of setts ( 52⁰C for 30 min.)
• Hot air treatment of setts ( 54⁰C for 2-3 hrs.)

Green muscadine

• Caused by Nomuraea rileyi and Metarhizium spp.
• At death, larva turns white and within few days gets covered with bright green fungal coating.

White muscadine

• Caused by Beauveria bassiana.
• Larva is mummified and gets covered by white powdery conidia.
• Brown plant hopper is prone to this disease.
