Effects of azadirachtin granules and standard insecticides in preventing root damage caused by Diabrotica v. virgifera in three potted -maize plant trials under greenhouse conditions in Hungary in 2020. is the current standard dose of the granular azadirachtin test product for soil applications (Neem Azaal 0.15G). General root damage assessed through 1.0 to 6.0 traditional IOWA scale (Hills and Peters 1971) and heavy root damage through 0.00 to 3.00 node-injury scale (Oleson et al. 2005). Experiment 1 and 3 with 5 plants per each of 3 blocks totalling 15 plants per treatment, experiments 2 with 4 such blocks totalling 20 plants per treatment. Plant roots artificially infested with 50 to 100 eggs and data standardised to 100 eggs. Games-Howell post hoc multiple comparison test at p < 0.05
