Seed handling & storage recommendations

 

Seeds are living organisms; careful handling and good storage can contribute to their high performance. Vegetables by Bayer recommends using vegetable seed in two years or less from purchase (depending on the crop). The following information can help achieve a good shelf life.

Storage temperature & humidity

 

High temperatures and humidity can affect seed by reducing its vigor and ability to germinate. Therefore, seed should be stored in a cool, dry area, out of the sun, and in unopened packages. Vegetables by Bayer packs its seed at industry-recommended moisture percentages, and packages must be kept unopened to prevent humidity from damaging the seeds. Cans, foils, and pouches are air and watertight.

 

Seed transport

 

When seed is shipped, it is advised to maintain the temperature and humidity conditions mentioned above. Avoid exposure to high temperatures or fluctuation in temperature during transport. Transporting seeds in temperature-conditioned containers is recommended. It should not be stored near a heat source or in direct sun.

Seed handling

 

It’s important to handle seed carefully to avoid damaging it. Seeds have a hard but fragile coating that protects the living organism within. Bean, pea, sweet corn, and pelleted seeds are especially susceptible to damage from rough handling (skin cracks or broken pellets). Bags of these seeds should not be thrown or dropped because the seed coats and embryos can crack, resulting in a seed that won’t develop properly.

 

Carry-over seed inventory

 

Vegetables by Bayer recommends that all seed be used in two years or less from purchase. A germination test update by an ISTA-accredited lab is advised on carry-over inventory, with a minimum of once per year before the sowing period.

Carry-over inventory is not advised for certain seeds:

  • Insecticide-treated seeds
  • Primed lettuce
  • Beans, onions

 

Seed storage recommendations

 

  • Store seed in the original package in an air-conditioned room with a storage temperature of 15°C (59°F)
    • Avoid temp above 20°C (68°F)
    • Avoid temp below 1°C (41°F)
  • Store seeds packed in paper bags at a relative humidity of 40-60%
  • Certain seeds are more sensitive and are labeled specifically with:
    • Store at 8°C
    • Store at 8°C and use within 12 months
  • Consider reduced shelf life once the package is opened.

 

Tip: use a household refrigerator for small quantities.
