Zeolite pesticide dusts

Abstract

Researches in order to obtain pesticidal dust (PD), which are employed against different pests in Agriculture,
the human and animal health protection and the environment hygiene, were resumed. The dusts were elaborated using
the usually denominated Polvos de ciclón as diluents, which are considered as residues of grinding industrial plants of
Cuban natural zeolites from the deposits Tasajeras y San Andrés, by means of the classical technology of Impregnation
with mixing–grinding–homogenization. The corresponding physical and chemical analysis, of the international established
parameters for the quality control, were made, first, to the elaborated formulations, and afterwards, these ones were
subject to one year storage at room temperature with the periodical interesting physical chemical controls. The contents
of the bioactive substances, or active ingredients, were determined for the insecticides fundamentally by means of Gas
Chromatography or High Performance Liquid Chromatography procedures, and for the fungicide using the international
procedure CIPAC MT 25. The quality parameters were determined with international standards, CIPAC and WHO
procedures. Satisfactory results using as diluents residues of grinding industrial plants of Cuban natural zeolites
were obtained, from the named deposits, with nominal formulations of Cypermethrin 2.5 DP, Permethrin 0.4 DP and
Propoxur 2.0 DP.
