Control of moths in stored grains

The Angoumois grain moth is the most serious pest injurious to rice, both in the field and storage.

This moth also attacks other cereals like maize, wheat and sorghum.

The infestation may reach serious levels before the grains are transported to the storage godowns resulting in around 25 per cent loss in weight and seed viability.

Internal pest

The larva is an internal borer of the whole grain, fe

Nursery management

 
•  Select well filled high density seed of variety suitable to the location/season by
    treating in salt water solution of specific gravity 1.08 (20 lt per 5 kg seed) prepared by
    dissolving 80 g common salt in one litre of water.
•  Plough the nursery area (1000 m2 per ha. of main field) at optimum moisture to get  
    fine tilth and prepare raised seed beds of 1.0 to 1.5 m w

Direct Seeded Rice

Rice can be directly seeded either through dry or wet (pregerminated) seeding.

Dry seeding of rice can be done by drilling the seed into a fine seedbed at a depth of 2-3 centimeters.

Wet seeding requires leveled fields to be harrowed and then flooded (puddling). The field is left for 12-24 hours after puddling, then germinated seeds (48-72 hours) are sown using a drum seeder.

Seed can be broadcast for either dry or wet seeding, but manual weeding is
