Effects of seed potato tuber treatment with imidacloprid on some soil and foliar insects in Croatia
The treatment of seed potato tubers by imidacloprid, as well as the standard granular insecticides applied in the furrow, did not, in four years of trials, sufficiently prevent damage from wireworms, noctuid larvae and mole crickets to potato tubers. The main reason for this failure is the spatial and temporal distance between application of insecticides and the moment when their action is needed. On the other hand, the effects of imidacloprid applied as seed tuber treatment on the larvae of the Colorado potato beetle was very good: depending upon conditions , it lasted at least 55, to 70 days at the most. It protected the foliage from any substantial damage from the entire first generation, and ensured high yields. Therefore a decision on seed tuber treatment with imidacloprid in Croatia should primarly depend upon the cost/benefit calculation based on damage expected from the CPB (or aphids), and not from soil insects pest.
