Silver plastic confuses aphids, blue plastic increases squash yields and red plastic boosts tomatoes.
Agriculture experts are not recommending that farmers turn their fields into a rainbow of colors, but they have observed that placing certain colored plastic on the ground around vegetable and fruit plants results in better production.
The concept was discussed Wednesday at the Western Maryland Ag Field Day, an annual conference that bring farmers, growers and the public up to date on the latest developments in agriculture.
About 600 people from Maryland, Pennsylvania and West Virginia attended the field day.
Dave Martin, the University of Maryland extension agent in Baltimore County, said it is not clear what causes different colors to spur plants on to better growth. The different colored plastics could cause temperature fluctuations that are good for certain plants, said Martin.
