STORAGE GODOWN AND THEIR MAINTENANCE
Maintenance of seed in godown following points are to be considered.
- Godown should be clean and dry
- Seed bags should not be stacked directly on floor. Should be stacked on wooden ballets.
- The height of the stack should not be more than 6-8 bags.
- Different seed lot should be kept separately.
- Godown should be sprayed periodically once in a week or fortnightly with Malathion 50 EC
(1 : 300 Chemical : Water) @ 5 lit. sq. m-1 or 0.25% Nuvan @ 1 lit. 100 m3-1.
- Altering the chemicals at weekly intervals will give better control.
- Seed lots can be fumigated with Aluminium phophide @ 3 gm/cu.m in air tight condition for 7 days. This can be done as propylatic measure and on minimum infestation by insects.
- Seed lots should be periodically (once in month) tested for seed quality.
- Based on seed testing result, seeds can be dried under sun for the removal of moisture. It reduces insect and pathogen infestation.
- New seed lots should be kept away from old seed lots to avoid secondary infestation of insects.
- Seeds should be treated with combination of fungicide and insecticide (eg.) Thiram @ 2 g kg-1 + carbaryl @ 200 mg kg-1.
- Frequent supervision of each and every lot is must.
- Seed bag should be restacked once in 3 months for free aeration.
- Instead of gunny bags low cost interwoven polythene bags should be used to prolong the life of seed.
- Pesticides, fungicides, fertilizers, rejects should not be stored with seed.
- Each lot should be labeled accurately and registers for stocks should be maintained.
- Per acre or per hectare packing (small) is preferable for easy handling and effective supervision.
