Bag la fusion ak konpoze Spiro ki gen atòm hetero yo pa fasil yo pwodwi rezistans akòz mekanis inik yo nan aksyon, epi yo te resevwa anpil atansyon nan devlopman nan pestisid. Pa egzanp: Rudi et al. rapòte 3,9-dichloro-2,4,8,10-tetraoksa-3,9-diphosphaspiro [5.5] undekane-3,9-dioksid ak sulfid Idwojèn te reyaji nan sentèz yon roman spiro konpoze, 3,9-dihydro-3,9-Dithio-2,4,8,10-tetraoksa-3,9-diphospho [5.5] andekane. Dérivés li yo se yon nouvo klas nan ensektisid organofosfat ak èbisid, sa ki ka efektivman retire moutad, ragweed, elatriye soti nan ble, sereyal, koton ak plant soya.

The fused ring and spiro compound containing hetero atom are not easy to produce resistance due to their unique mechanism of action, and have received extensive attention in the development of pesticides. For example: Rudi et al. reported 3,9-dichloro-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane-3,9-dioxide and sulfide Hydrogen was reacted to synthesize a novel spiro compound, 3,9-dihydro-3,9-dithio-2,4,8,10-tetraoxa-3,9-diphospho[5.5]undecane. Its derivatives are a new class of organophosphate insecticides and herbicides, which can effectively remove mustard, ragweed, etc. from wheat, cereals, cotton and soybeans.
