| Abstract | ||
| The present study aimed to prepare certain formulations that contain an acaricide (abamectin) and one of plant growth regulators (b-Naphthoxy acetic acid [NAA] or 6-benzylaminopurine [6-BAP]). The study also investigated the effect of pH and total soluble salts of certain types of diluted water on the physical and chemical properties of those formulations. The purpose of combining the two active ingredients (acaricide and a plant growth regulator) is to save time and money of the application. Water analysis revealed that different types of collected water from different sources had an alkaloid level where pH values were more than 7.0. It can also be seen that underground water the highest value of pH was (8). The results indicated that Beta 410® and Cyto G 5%®reduced the pH value of the all tested water sources to be in the acid range (5.5). Both Beta 410® and Cyto G 5%® acted as plant growth regulators and they were useful for lowering the pH of the ground water that has been used for dilution. Therefore, they can act as buffering agents where the ground water is still being used for dilution of pesticides. The study also investigated the effect of salinity of different tested types of water on the stability of the prepared emulsifiable concentrate formulations. The results of testing each component alone (Beta410®, Cyto G® and Abalone®) showed that these tested ingredients were stable in all tested water samples, exception underground water with the formulation (Abalone + Cyto G). | ||
