Seed storage godown sanitation

• Storage environment should be free from insects and rodents
  
• Chemicals such as insecticides, fertilizers should not be stored along with seeds.
  
• Storage room should be kept cool and dry
  
• Fumigation may be done whenever needed
  
• Use wooden pallets for arranging the bags in cris-cross manner for effective ventilation on all sides of the bags.
  
• Seed bags should be stacked upto 6-8 tires depending upon density of seeds
  Restocking once in 3 months or less is important for prolonging seed viability
  
• Before storage disinfect the godowns by spraying malthion 50% E.C. @ 5 lit /100 m2 areas.
  
• If old gunnies, cloth bags and containers are to be used these should be fumigated with aluminium phosphide.
  
• Size of the stack should be 30x20 feet facilitate fumigation under gas proof or polythene covers.
  
• Periodical inspections should be carried out and control measures to be taken i.e malthion 50% E.C. @ 5 lit /100 m2 area should be applied in every 3 weeks
  
• It must be borne in mind that fumigation, particularly repeated fumigation, may seriously reduce the vigour and even the germination capacity of seeds. Seeds with m.c. greater than 14% should be dried to below this value before fumigation
