Investigation of some alternative methods against pear Penicillium expansum in korkuteli̇ cold storages

In this study, the effectiveness of antagonistic microorganisms (Bacillus subtilis, Trichoderma harzianum) and thyme essential oil for the control of Penicillium expansum disease, which causes significant post-harvest losses in pears in cold storage in Korkuteli district of Antalya, in vitro and in vivo conditions were investigated. Trials were carried out at Korkuteli Cold Storage and ISUBU Faculty of Agriculture Biotechnology Lab. In both trials, all trials significantly decreased (P≤0.05) rot lesions compared to the control. In the experiment conducted at the ISUBU Faculty of Agriculture Biotechnology Laboratory, control (4.76 cm) of rot lesions compared to control, while the test of Thyme oil reduced contact with 500 µl / L (1.29 cm), the test of Thyme oil fumigant was 1%. In the trial conducted in the Korkuteli Cold Storage, the control (3.92 cm) of the rot lesions decreased according to the control, while the test of the Thyme oil contact reduced 500 µl / L (1.30cm), Thyme oil contact 100 µl / L (3.05 cm) trial had the lowest effect. As a result of the studies, it was concluded that it would be beneficial to use thyme essential oil and antagonistic microorganisms (Bacillus subtilitis., Trichoderma harzianum) both are environmentally friendly, againist post-harvest Penicillium expansum disease in pears.
