Fethiye-Turkey

Taumetopoea pityocampa (Den. and Schiff.) is the most important coniferous pest in Turkey. Although several methods have been used in attempting to control this major forest pest up to now, the problem still remains largely unsolved in Turkey. In order to control this pest, we planned and applied field treatments for experiment. Foray 76B and VBC 60074 bioinsecticides including Bacillus thuringiensis subsp. kurstaki were sprayed on Pinus brutia trees. The experiment was two-factor randomised complete block design within three blocks having a size of 1.5 ha. Each block was subdivided into three plots having a size of 0.5 ha. The buffer zones were then established to avoid cross contamination from treatments between the blocks and plots. Foray 76B was applied at the rate of 2.5 l 50 BIUha-1 and VBC 60074 at the rate of 0.6625 kg + 2.5 l water 50 BIUh
