The pesticidal effectiveness of metaldehyde, which is difficult to dissolve or disperse, can be improved by mixing it with one or more surface active agents and milling to a fine particle size, preferably less than 30 microns, and subsequent application, optionally with the addition of a suitable film-forming polymer, such as a styrene acrylic latex, to a carrier material such as bran. meal, grain, flour or finely divided silica. Finely milled metaldehyde formulations made this way are highly effective molluscicides.
On peut améliorer l'efficacité comme pesticide du métaldéhyde, lequel est difficile à dissoudre ou à disperser, en le mélangeant avec un ou plusieurs agents tensioactifs et en le moulant jusqu'à l'obtention d'une fine granulométrie, de préférence de moins de 30 microns, et en l'appliquant subséquemment, éventuellement en y ajoutant un polymère filmogène approprié, tel du latex acrylique de styrène, à un matériau-véhicule tel le son, la farine, des graines, ou du silice finement divisé. Des formules de métaldéhyde finement moulues préparées selon ce procédé sont des molluscicides hautement efficaces.
