The present invention relates to the promotion of a continuous chemical barrier of a soil-born invertebrate pest control agent in soil in a locus where soil-borne invertebrate pests are suspected or known to exist. In particular the present invention relates to compositions of liquid soil-borne invertebrate pest control agents and selected adjuvants wherein the adjuvant improves the downward and lateral movement in the soil of the soil-born invertebrate pest control agent contained in the liquid soil-borne invertebrate pest control agent. The invention set forth herein finds particular utility with soil-born invertebrate pest control agents with a water solubility of 3 ppm, or less, such as bifenthrin.

Effectiveness of invertebrate pest-control agents

A procedure for the treatment of roots of seedlings whereby the roots are provided a water-rich coating, having a surface sufficiently dry and moisture-stable to permit the seedlings to remain discrete and to preserve the integrity of the coating during ordinary handling and planting operation, but sufficiently moisture-sensitive so that soon after planting, the coating disintegrates and releases the pesticide, thus providing the plant protection against pests over an extended period of time. The method is applicable with insecticides, nematicides and fungicides, whether these pesticides are systemic or non-systemic.
