Seed Health

Seminis designed the SHIELD program to ensure seed health through meaningful innovation.

Seminis is committed to providing growers with healthy vegetable seeds. To ensure that we offer you the best options available when it comes to seed health, we developed our SHIELD program. SHIELD is a comprehensive care program that unites seed sanitation, seed health testing and field inspection in a way that provides you with optimum seed health. SHIELD stands for:

• SHIELD is committed to providing growers with healthy vegetables through:
• Assurance that our customers are purchasing clean and high-quality seeds.
• Collaboration with national and international industry seed health groups to keep the worldwide seed supply healthy and robust for growers.
• Accessibility to information, technology, and seed health education and training to support growers’ knowledge of seed health standards, testing and field management.
• Plant pathology to ensure seeds are protected from both existing and newly developing diseases.
• Testing and tracking for seed-borne diseases to maintain healthy seeds.
• Technology, which is the foundation for promptly resolving seed health problems and for supplying clean seeds.
• Every Seminis customer can count on the added assurance provided by the SHIELD program with every unit of seed purchased.

Seed Temperature

High temperatures and humidity may reduce seed vigor and germination. Therefore, seed should be stored in a cool, dry place, out of direct sunlight and in closed containers. Seminis packs its seed at industry-recommended moisture percentages. Containers must be kept closed to prevent humidity from damaging the seeds.

We recommend storing untreated seed, and seed treated with fungicide at 15°C (60°F). Seed that is either primed or treated with insecticide should be stored between 1°C-5°C (33.8°F-41°F). Generally, every 5°C decrease of storage temperature doubles the average shelf life of the seed.

Seed Shipping

When seed is shipped, it needs the same temperature conditions it requires when in storage. It should not be stored near a heat source or in direct sun. When on board a ship, seed should be stored below the deck and away from boilers and other sources of heat. While loading and unloading, avoid placing the seed in direct sunlight or in hot or humid places.

Seed Handling

Seed can be damaged by rough handling. Seeds have a hard, but fragile coating protecting the living organism within. Corn, pea and bean seed are especially susceptible to damage from rough handling. 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.

Germination Tests

We recommend that each seed lot have a germination test every six months (every three months for primed seed). The germination test should be conducted by a laboratory test under ISTA or other nationally or internationally recognized rules. Germination results from field tests may vary from laboratory results and should not be used for labeling.

Primed seed

Some seed is primed, a process that brings the seed close to the point of germination. Priming the seed may help the seed grow, especially under stressful conditions. Because the priming process reduces the shelf life of seeds, primed seed should be planted in the same year it is primed.

Seminis recommends primed seed be stored between 1° – 5°C (33.8° – 41°F). It should also have a germination test every three months.

Post Priming Technology

Post Priming Treatment is the latest innovation from Seminis. It’s a seed enhancement technology that extends the life of a farmer’s primed seed for months, not weeks. Not only will it improve seed longevity, Post Priming Technology also increases the potential for the seedlings to emerge faster, more uniformly and better equipped to withstand the stresses of a wider range of environmental conditions.

Seminis Post Priming treatment is available for tomatoes, peppers, onions and cucurbits.

Pelleting

Seminis offers coating applications essential for optimum performance. Seminis pelleting is available on Seminis lettuce, onion, tomato and carrot seeds. The powders used in our pelleting process combined with our advanced genetics, produce optimal performance in both harsh and normal climate conditions.

Germination Tests

Seminis recommends that each seed lot have a germination test every six months (every three months for primed seed). The germination test should be conducted by a laboratory test under ISTA or other nationally or internationally recognized rules. Germination results from field tests may vary from laboratory results and should not be used for labeling.
