Sažetak
Investigation into mating disruption method in the control of codling moth by using Isomate C TT dispensers (SHIN ETSU®) with a dose of 500 dispensers per hectare + 50 dispensers for edge reinforcement was carried out in the apple orchard Nedelišće (Međimurje) in 2017. The mating disruption method was applied on 2 hectares of orchard, 1ha below antihail nets and 1 ha out of the antihail net. An assessment of the effectiveness of mating disruption and the standard program in which protection was carried out by applying 6 insecticides was carried out at harvest time of apple cultivar ‘Idared’. The survey shows the cost f dispensers per hectare and the average price of applied insecticides, as well as the economic losses expressed in terms of yield (kg of fruits) and in the national currency (HRK) per experiment variant per hectare. The highest protection efficacy was achieved with 92.65% in the standard part of the orchard, and the efficacy on mating disruption was 67.65% and 73.53%, which is not economically justified with regard to the costs of protection and firstclass fruit losses. The investigation confirmed that the mating disruption method must be combined with the application of two insecticide treatments to increase the efficacy and profitability of apple production.
