ABSTRACT:
Methods for protecting plants from insects are provided. Such methods comprise: applying a formulation comprising partially-desiccated nematodes and a carrier to plant surfaces growing above the surface of the ground (i.e., foliage). Such formulations have a water activity (Aw) of which is less then 0.998 and greater than 0.935. The carrier comprises water and a substance which maintains the water activity of the formulation at levels of from about 0.980 Aw to about 0.940 Aw for a period of 24 hours when the formulation is exposed to air at 70% relative humidity and 25° C. In one embodiment, the carrier is a solution or gel comprising water and a water-retentive polymer. In another embodiment, the carrier is a solution which comprises water and a humectant. In a further embodiment, the formulation comprises both a water-retentive polymer and a humectant. Preferably, the formulation further comprises an ultraviolet (UV) light protectant. In another aspect, the present invention relates to the formulations that are used in such methods.
