ACTIVITY : Insecticide; Acaricide; Arachnicide; Nematocide; Antifouling. In a trial against Phaedon cochleariae larvae on cabbage leaves, a composition containing 20 ppm 2-oxo-3-(2,5-dimethylphenyl)-4-ethoxycarbonyloxy-5-(spiro-(4-methoxycyclohexyl))-2,5-dihydropyrrole gave 0% kill after 6 days, and a composition containing 100 ppm 2-oxo-3-(2,4,6-trimethylphenyl)-4-((2,2-dimethylpropylcarbonyloxy)-5-(spiro-cyclopentyl)-2,5-dihydrofuran gave 35% kill. A composition containg the specified amount of both compounds gave 75% kill. MECHANISM OF ACTION : None given.
