Control Of Trialeurodes Vaporariorum (Westwood) Adults On Glasshouse-Grown Cucumbers In Four Different Growth Substrates: An Efficacy Comparison Of Foliar Application Of Steinernema Feltiae (Filipjev) And Spraying With Thiamethoxamn, Ziga Laznik, Dragan Znidarcic, Stanislav Trdan

Turkish Journal of Agriculture and Forestry

In a glasshouse experiment, the effectiveness of the entomopathogenic nematode (EPN) Steinernema feltiae (Filipjev) (Rhabditida: Steinernematidae) was compared with thiamethoxam for the control of adults of the greenhouse whitefly (GWF), Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae), on slicer cucumbers. In a period from mid June to the end of August (2007 and 2008), cucumbers were grown in 4 different growth substrates: expanded perlite, expanded vermiculite, light expanded clay, and peat. A suspension of the nematode (2500 infective juveniles mL^{-1}) was applied to cucumbers 5 times in 2007 and twice in 2008, whilst an insecticide thiametoxam at the recommended dose (0.7 g …

Biological Control Of Chestnut Canker, Caused By Cryphonectria Parasitica, By Antagonistic Organisms And Hypovirulent Isolates, Seçi̇l Akilli, Yakup Zekai̇ Katircioğlu, Sali̇h Maden

Turkish Journal of Agriculture and Forestry

Biological control of chestnut blight was investigated by using 3 hypovirulent isolates of Cryphonectria parasitica, 5 Trichoderma sp., 4 Penicillium sp., and 4 Bacillus sp. isolates. Hypovirulent isolates and antagonistic organisms were obtained from samples collected from the Black Sea region of Turkey, in 2008 and 2009. Effectiveness of the hypovirulent isolates and antagonistic microorganisms was tested on 3-year-old chestnut saplings. In the tests, bark disks of 6 mm were removed from the stem bases and culture disks of the virulent isolate of C. parasitica were first placed into the hole and then the hypovirulent isolate or the antagonistic fungi. …
