Seed treatmentSeed treatment

Seed treatment is a process of application of

chemicals or protectants (with fungicidal, insecticidal,

bactericidal or nematicidal properties) to seeds, thatprevent the carriage of insects or diseases causing

pathogens in/on the seeds.

Seed treatment also enables the seed to overcomeseedling infection by soil borne fungi.

Methods of seed treatment

1. Dust treatment

Bulk of seed is treated by dust formulations whichdo not require very complicated equipments.

Factory made closed barrel type rotating drums areused for seed treatment which reduce the inhalationhazards.

2. Wet treatment

Water soluble chemical are dissolved in water incontainers of convenient size and seeds are droppedfor a certain period of time (short dip/long deep) andthen dried properly before packing and storage.

If the seed is not properly dried, it is likely to bedamaged during storage

Metallic containers should not be used whenmercurial compounds are chosen for seed treatment.

3. Slurry method

This method is most suitable for applying wettable powder

formulation.

The chemicals are mixed with a small quantity of water andthen the mixture is applied to seeds in automatic or semi-

automatic machines for large scale seed treatment.4. Pelleting

It is used mostly as protectant against soil organisms and as

a repellent against birds and rodents.

The method has very limited application hence it is notextensively used.

Rice seed treatment before seeding

Pour seeds in made of clothes or gunny bags and

tie loosely

Mix 3 g of Bavistin/Noine/Evazim/Gilzim/Topcil

plus/Hedazim/Sunfanet with 1 l of water in a pot for1 kg of seed

Dip the seed bag in the treated water for 24 hours.

Treated rice seeds prevents the seed borne fungal

diseases like Bakanae, Leaf scald, Sheath rot, Blast,

Brown spot, False smut.

Land preparationLand preparation

Cross ploughing twice and wait for 7- 8 days

Again ploughing twice followed by laddering

and 3-4 days and then final land preparation

Properly level the land for better water and

weed management

Crop establishment and managementCrop establishment and management

Crop establishment methods1. Dry seeding ( using PTOS, VMP)

a) Zero tillage (relay cropping)

b) Reduced tillage

- Full tillage single pass- Strip tillage

- Bed planting

c) Dibbling (manage drought & salinity)

2. Wet seeding (using drum seeder)- Line sowing

- Broadcasting

3. Transplanting
