This study carried out to elucidate the synthesis of MCPP-LDH hybrid, release pattern and their properties. MCPP-LDH hybrid was synthesized from MCPP and Mg-Al complex. Release kinetics of MCPP from MCPP-LDH hybrid was slower in distilled water and soil solution but it was slower in distilled water than soil solution. MCPP-LDH hybrid has shown more stable condition than CO32- form of LDH in thermal and acidic condition. Clover (Trifolium pratense) seed germination experiment was tested in soil. After 40 days observation, seeds were partially germinated when they were treated with MCPP but these were totally inhibited when treated with MCPP-LDH. Therefore, MCPP-LDH hybrid would lead as functional and benign pesticide to minimize the harmful effects on soil environment by bulk herbicides.
