A new unique and novel formulation was developed using microporous and mesoporous zeolites 4A, loaded with methyl eugenol (ME) and in combination with the ME loaded and pH adjusted carbopol 940 aqueous gel. The developed formulation with the entrapped ME in the organo-inorganic matrices resulted in slow and sustained release of ME at constant rate for 56 days when deployed in the agriculture fields. The formulation can be effectively used for monitoring, mass trapping and controlling of fruit fly pest. Molecular sieves in the inorganic matrix of zeolites 4A helps in the sorption of the pheromones and exhibits the synergic sustained release effect, when combined with the pH stabilized ME loaded carbopol 940 gel. By adjusting the pH of the matrix system, an average sustained release of 33.33±0.06 mg of ME per day was achieved continuously for 56 days, by a loading dose 2gms of ME into the zeolite 4A dispersed carbopol 940 gel; angstrom void polymer (AVP) gel matrix formulation (patent applied).
