Abstract
The research work carried out the period 1999-2002 in Viticulture Research Station Murfatlar and the results obtained revealed a good efficiency of using biological and biotechnical methods in integrated control of grape moth. Work was done using Romanian pheromone traps “atraBOT”, in order to establish the flight curves, supervise the populations according to the economic threshold (100 males butterflies/trap/week) and control the moth by a mass capture of males with 3, 6 and 9 traps/ha. The biopreparations Dipel ES at a rate of 1.0 L/ha, Ecotech-extra at 1.5 L/ha and Foray (Biobit) at 1.5 L/ha, based on Bacillus thuringiensis was applied especially for third generation of grape moth with good results. A good efficiency in chemical control of the pest Lobesia botrana was obtained with Larvin 375 at a rate of 1.0 L/ha; Bulldock 25 EC at 0.3 l/ha; Enduro 258 EC at 0.3 L/ha; Reldan 40 EC at 1.25 L/ha; Polytin 200 EC at 0.1 L/ha; Karate Zeon at 0.25 L/ha; Decis 25 EC at 0.3 L/ha and Total 60 EC at 1.5 L/ha. The best results in controlling this pest were obtained with new cloronicotiniles like Actara 25 WG at a rate of 100 g/ha and Calypso 480 EC at a rate of 100 ml/ha and also with mixture between Dipel ES 0.5 L/ha and Actara 25 WG at 50 g/ha or Calypso 480 EC 50 ml/ha, both at half of its usual rate.
