Abstract
- The objective of this study was to assess the toxicity of two pesticides (Prosaro<superscript>®</superscript> XRT and Decis<superscript>®</superscript> EC 25) widely used in the agricultural region of El-Tarf located in northeastern Algeria, as well as their combinations on a variety of durum wheat “Triticum durum Desf”. The toxicity of these products was evaluated using physiological (chlorophyll) and biochemical parameters (proteins, glutathione, catalase activity and glutathione S-transferase, acetylcholine esterase, lipoxygenase). The recommended dose and its double were tested individually and in combination for this. It should be noted that the protocol used and the initial concentrations selected are the same as those used in the field. After D7 and D14 of exposure, all dosages were administered. The results obtained revealed a decrease in chlorophyll contents and Glutathione levels as well as an induction of total proteins and the differents enzymatic activity (catalase, glutathione S-transferase, lipooxygenase) and this for the two root and leaf compartments. Thus, it turns out that the concentrations used in open fields are not harmful to the plant but generate free radicals which are taken care of by the latter’s defense system, thus allowing it to tolerate these stress conditions.
