C&EN Senior Business Editor Melody Voith describes a boom in developing and producing chemical coatings that act as built-in pesticides to protect seeds from destructive insects, fungi, and other pests. Seed treatments for protecting cereal, corn, and beet crops already are common in agriculture and are growing in popularity in an effort to safeguard genetically modified seeds, which are expensive. The worldwide seed treatment market now generates $1.5 billion yearly and is growing at 10 to 12 percent annually, according to the article.
Voith notes that scientists are also developing a new generation of seed treatments that use microorganisms to protect plants from pests and promote earlier, more vigorous growth. One company, for instance, produces a bacterial coating that kills disease-causing fungi while secreting a substance that promotes plant growth. Unlike chemical treatments, which last for weeks, these biologic seed defenders last for months.
