PCT No. PCT/HU83/00014 Sec. 371 Date Dec. 2, 1983 Sec. 102(e) Date Dec. 2, 1983 PCT Filed Apr. 6, 1983 PCT Pub. No. WO83/03521 PCT Pub. Date Oct. 27, 1983.The invention relates to a microencapsulated insecticidal composition containing isopropyl (2E,4E)-3,7,11-trimethyl-11-methoxy-2,4-dodecaidenoate which comprises 45-95% by weight of isopropyl (2E,4E)-3,7,11-trimethyl-11-methoxy-2,4-dodecadenoate as active ingredient, 1-15% by weight of butyl hydroxy toluene and 5-40% by weight of activated charcoal, in the form of powdery microcapsules having a grain size of 1-300 mu m and coated with a hydroxypropyl methyl cellulose phthalate or cellulose acetate phthalate polymer. The advantage of the microencapsulated insectidical composition according to the present invention resides in the increased stability.
