Abstract
The present invention relates to agricultural methods and the use of 3-arylquinazolin-4-one derivatives of formula (I) wherein R1, R2, R3, R4, k and n are defined in the description in soil application methods. The compounds of the formula (I) are highly suitable for controlling animal pests such as insects and/or spider mites and/or nematodes by treating the soil/growth substrate by drenching or drip application or dipping or soil injection.
