3-(5-tetrazolylcarbonyl)-2-quinolones and crop protection agents comprising them

摘要

The invention relates to substituted 3-(5-tetrazolyl carbonyl)-2-quinolones of general formula (I) and to products for protecting useful plants containing the same. In said general formula (I), -A<1>-, -A<2>- and -A<3>- can each mean a direct bond or a divalent carbonyl analogue group, and X<1>, X<2>, X<3> and X<4> mean different organic radicals. The inventive products can be used to reduce the unwanted damage caused to useful plants by herbicides.
