Abstract: | The extensive use of pesticides in agriculture in particular herbicides is a serious environmental threat. There is an urgent need to develop pesticide formulation that combines optimum bioactivity and minimum dosage. In the present article an attempt has been made to design granular formulation of one of the most commonly used herbicide, atrazine (AT). This potent herbicide along with kaolin as the carrier and suitable clay modifiers can be thought as one of the potential way of formulation keeping in view the desired dosage and bioavailability of the same. The process of granule formulation was carried out using the principle of rapid mix granulation. These granule formulations were then compared with the other formulation where the clay was not modified with the help of parameters such as dissolution rate, dispersion stability and wetting time. The study reveals a very positive effect of clay modifications on granules in terms of above mentioned quality parameters. |
