IMPROVED METHODS FOR CONTROL OF SOIL-DWELLING PESTS AND/OR SOIL-BORNE DISEASES

摘要

A method for the control of soil-dwelling pests and/or soil-borne diseases comprising treating a plant propagation material with an effective amount of the pesticidal composition and/or applying an effective amount of a pesticidal composition to a locus where control is desired, provided that the composition comprises, as active ingredient, one or more pesticides (A) having a water solubility of at most 100 µg/litre, at 25 °C at neutral pH, and at least one formulation auxiliary, wherein the size of particles in the composition is in the range 3.60 µm to 0.70 µm at X₉₀. Abamectin has been found to be particularly effective against nematode damage.
