Insecticidal or nematicidal composition, processes for the preparation thereof, and use in method for controlling insects and/or nematodes.

摘要

An insecticidal or nematicidal composition comprising particles of an inert carrier, oxamyl (methyl 2-(dimethylamino) -N-[[(methylamino)carbonyl]oxy]-2-oxo-ethanimido-thioate) and a barrier material, capable of providing a controlled release of oxamyl in water. Processes for the preparation of the composition and the use of the composition in controlling insects and/or nematodos are described. The composition is especially of use in the prolonged control of root knot nematodes.
