<p>The present invention relates to a phosphine-producing pesticide based on alkaline earth metal phosphides or earth metal phosphides and, if appropriate, additives, which pesticide is coated to delay fumigation, the coating is moisture-permeable in a controlled fashion and consists of a solid organic material which completely surrounds the phosphine-producing substance or the phosphine-producing composition. The invention furthermore relates to a process for controlling the fumigation time of phosphine-producing pesticides based on alkaline earth metal phosphides or earth metal phosphides and, if appropriate, additives and with a coating to delay the fumigation, in which process the pesticide which exists in the form of shaped articles, preferably of regular shape with rounded edges, in the form of granules or powders, is completely surrounded with a coating made of a solid organic material and whose moisture permeability can be regulated, and which is subjected in a known manner to fumigation conditions, the pesticide preferably not containing any specific disintegrants.</p> |
