Influence of wireworm control on yield and forage quality in silage maize production.

摘要

Without effective control of wireworms [Elateridae] in the field in Germany, the dry matter yield of maize and starch content decreased significantly by 31 and 8%, respectively (based on data from 1999). The application of carbosulfan and imidacloprid in particular resulted in lower losses of maize plants. The higher the yield losses caused by elaterids, the higher the costs per unit of silage dry matter and feed energy. At a maize yield level of 45 t fresh matter/ha, the cost of production increased by about 25%, if heavy losses by elaterids occurred. At a yield loss rate of 10%, the costs for seed treatment against elaterids were already lower than the costs for the replacement of the maize silage losses.
