| Abstract:
During three seasons in years 1999-2001, experiments on control of the twospotted spider mite (Tetranychus urticae Koch) on black currant plantations were conducted in Skierniewice, Poland. Envidor 240 SC (spirodiclofen) at the rates of 0.3 and 0.4 l per ha was used just after blooming, and at the rate of 0.4 l per ha - just after fruit harvest. Envidor 240 SC at rates 0.3 and 0.4 l/ha was applied as a single spray treatment just after blossom of black currant and provided satisfactory control of the twospotted spider mite, with long lasting effect, up to 2-6 weeks, depending on plantation. These results were nearly as good as or equivalent to the standard acaricides, Magus 200 SC (fenazaquin), Omite 30 WP (propargite) and Ortus 05 SC (fenpyroximate). Envidor 240 SC at the rate of 0.4 l per ha was applied as a single spray treatment just after harvest and gave satisfactory control of the twospotted spider mite for at least 4 weeks, up to the end of the growing season. Envidor 240 SC, after being registered, could be used to control the twospotted spider mite on black currant just after blossom or after harvest. It would be also suitable to protect currant plantations in the Integrated Fruit Production (IFP) programme. | |
