| Abstract | ||||
| Three pesticides in liquid formulation were collected in their commercial packages (high density/polyethylene) (HD/PE) and stored under tropical conditions at (54±1°C) for three days. The effect of these packages on physico-chemical properties of tested pesticides and their spray solution compared with that stored in glass container was studied. The tested pesticides were : benthiocarb EC (Saturn), glyphosate SL (Glialka), and glyphosate SL (Pilarsato). The obtained results clearly shows that, the physico-chemical properties of tested pesticides and their spray solutions influenced with (HD/PE) packages through storage under tropical conditions (54±1°C) for three days compared with glass container. This influencing was recorded as changes in one or more of physico-chemical properties of these pesticides or their spray solutions upwards of that stored in glass container. On the other hand, these changes were between improvement effect and bad effect. The bad effect in case of tested pesticides formulation was noticed only in case of physico-chemical properties that were unstable before storage (foam of glyphosate SL "Pilarsato" 48 % and emulsion stability of benthiocarb EC 50 %. The above indication was not noticed in case of spray solution of these pesticides. Although the stored of benthiocarb (Saturn) and glyphosate (Pilarsato) in (HD/PE) packages showed several improvement effect on physico-chemical properties of this pesticides and their spray solutions upwards of glass container, it did not pass successfully through physico-chemical properties tests. With other view, the effect of (HD/PE) packages depending on component of tested formulations as recorded with glyphosate SL 48 % that produced by two companies in two different formulations. The common name of the first one was Glialka SL 48 % produced with Cardl-Agro Co. and the second was Pilarsato SL 48 % produced with Acta Co. There are no bad effect was noticed from tested packages on the first one, and their spray solutions, while bad effects were noticed with the second one as increase in foam %. | ||||
