摘要

Use of amino-substituted nitrogen heterocycles (I) for treatment of seeds. Use of amino-substituted nitrogen heterocycles of formula (I) for treatment of seeds. R 1>optionally substituted 5- or 6-membered aromatic heterocycle containing N; X : optionally substituted alkylene or alkylidene; R 2>hydrogen, (cyclo)alkyl, (cyclo)alkenyl or aryl (all optionally substituted) or YR 3>; Y : O, S(O) l, CO or COO; l : 0-2; R 3>hydrogen, (cyclo)alkyl, (cyclo)alkenyl, alkynyl or aryl; A, B and D : optionally substituted C, a heteroatom or a single bond; E : CO or CS; Q : hydrogen, alkyl, alkenyl, alkynyl or aryl (all optionally substituted), nitro, halo or ZR 4>; Z : CO, COO or S(O) m; m : 0-2; R 4>(cyclo)alkyl, (cyclo)alkenyl, alkynyl or aryl (all optionally substituted). An independent claim is also included for a method for controlling animal pests on plants that comprises application of (I) to the soil. [Image] ACTIVITY : Insecticide; Arthropodicide; Arachnicide; Nematocide; Antifouling; Acaricide. A composition containing 3-(N-methyl-N-(2-chloropyridin-5-ylmethyl)amino-2-oxo-1,4-dihydrofuran (Ia), at 4 g/kg, was applied to seeds of cotton, then these planted and 2 weeks later the cotton plants were infested with Aphis gossypii. After 7 days the control of aphids was 100%. (Ia) was also active, from a seed dressing, against A. fabae on beans and Rhopalosiphon padi on barley. MECHANISM OF ACTION : None given.
