Advances in the Technology for Controlled-Release Pesticide Formulations
The choice of formulation is influenced by the following factors: the physical properties of the pesticide (melting point, solubility, and volatility), the chemical properties of the pesticide (hydrolytic stability, thermal stability, and irradiation stability), the mode of application of the formulation (soil, foliar), the crop to be treated and the agricultural practices, the biological prope...
متن کاملControlled Release Gel Formulations
Simple gel formulations may be applied to enhance the systemic and local exposure of potential compounds. The aim of this thesis is the development and characterization of controlled release formulations based on thermoreversible poloxamer gels, which are suitable for novel drug delivery applications. In particular co-solvents (DMSO, ethanol), mucoadhesive polymers (chitosan, alginate) and salt...
متن کاملReduction of Pesticide Pollution in Agricutural Soils by Using Controlled Release Formulations: Efficacy and Persistence Studies
The application rates for conventional herbicide formulations are generally greater than the recommended dosage, in order to overcome losses from degradation, leaching, volatilization, and sorption during the time needed for weed control. All these factors have encouraged the development of controlled release formulations (CRFs), which can reduce herbicides levels in the environment since less ...
متن کاملEvaluation of controlled-release mosquito repellent formulations.
Eight polymer and 9 microcapsule formulations of deet were tested on laboratory rabbits against Aedes aegypti and Anopheles albimanus. Several formulations were significantly more effective than simple (unformulated) deet at the same strength for periods up to 24 h. Best results were obtained with a polymer formulation containing a high molecular weight fatty acid and 3 microcapsule formulation...
متن کاملDevelopment of controlled release formulations of thiabendazole
This study aimed to develop controlled release formulation of Thiabendazole for reduced contaminations to soil water and agricultural produces. The idea behind this work was based on changing the ionization status of Thiabendazole molecule throughout pH changes to become a cation then adsorbing it to bentonite clay surfaces. Equilibrium concentrations of Thiabendazole in the adsorption solution...
