Economic-yield efficiency of insecticides used for control of aphids Aphididae in case of field beans cultivation

摘要

The paper presents an attempt at defining economic-yield efficiency of two methods for control of aphids on field beans: dressing of seeds with insecticides and traditional spraying. Economic efficiency of aphids control was high, higher in case of spraying than in case of seeds dressing. The high costs of seeds dressing were determined mainly by high costs of dressing media. The costs of protection in the experiment were equivalent to the value of 7,90 dt of field beans seeds in case of dressing and 0,60 dt in case of spraying.
