Abstract


Six insecticides at various rates and formulations, applied by three methods over three seasons, were evaluated for controlling the European wireworm. <i>Agriotes obscurus</i> L. in corn planted in silt loam. The insecticides were in granular form, applied as a broadcast, in a band, or in the seed furrow. Most of the materials, rates and methods gave good protection. Insecticide applied in the furrow was placed either in contact with the seed, or just ahead of it and mixed with soil. When it was in contact with the seed the yield was slightly lower, indicating some phytotoxicity. The furrow methods were the most economical in material and labour.
