3
Larger Grain Borer (LGB) – (Prostephanus truncatus- Scania)

Adults bore into rice husks, producing large quantities of grain dust as they tunnel.

4
Pre-and Postharvest Management of Mycotoxins in Rice

Mycotoxins are poisonous substances produced by some molds, which grow on foods such as cereals, oil crops, fruits under moist and humid conditions.

5
Pre-harvest Rice Management

Time from planting to harvesting varies from 4 to 6 months. Rice is ready for harvesting when:

7
Rice Milling

De-hulling is removing of husks to get brown rice, Milling is the process of removing bran and polishing is the process of getting white grains.

8
Rice Postharvest Handling

The postharvest system consists of a set of operations from harvest to consumption

9
Rice Storage

Safe storage of rice for longer period is possible if three conditions are met:
- Grain is maintained at moisture content of ≤14%.

10
Rice Value Addition

Value addition enhances profitability of rice production.

11
