As selected wavelengths of light are reflected from the silver surface, flying insects, for example aphids and whiteflies, are repelled from landing on the plants. Therefore the insects do not feed on the plants and spread deadly crop viruses.

Springtime soil temperature under SRM-Silver mulch is generally 1 to 3 degrees lower than under black mulch; therefore, in northernstates early crop production might be slightly delayed. Particularly in more southerly states where fall crops are normally planted, SRM-Silver mulch is very beneficial in thwarting flying insects and ultimately resulting in higher yields because of the reduced incidence of plant viruses.

Advantages of SRM-Silver:

• Repels flying insects.
• Reduces virus diseases.
• Improves yields.
• Conserves moisture and nutrients.
• Weed control

1. Prepare soil well. It should be smooth and pliable.
2. Do not lay plastic on dry soil.
3. Carefully adjust plastic laying machine.
4. Plastic should be in close contact with the soil for maximum heat transfer into the soil.
5. Be sure the edges of the plastic are well secured with soil.

• Vegetables -- warm season crops that are subject to infection with viruses such as tomatoes, pepper, and summer squash.
• Cut flowers where viruses are known to be a problem
