Özet:

 The Bacterial Speck Disease, caused by Pseudomonas syringae pv. tomato Pst, represents a significant bacterial ailment with a notable impact on tomato plants. This study aimed to ascertain the susceptibility levels of Pst isolates obtained from various fields in the Karataş district of Adana province, Turkey, when exposed to copper-containing pesticides under both in vitro and in vivo conditions. The results from in vitro efficacy experiments revealed that all isolates exhibited growth on nutrient media supplemented with 30, 60, and 90 μgml doses of copper sulphate. However, they failed to grow on media containing 120 and 150 μgml doses of copper sulphate, indicating the absence of resistance in the Karataş Pst isolates towards copper-based preparations. Furthermore, greenhouse-based in vivo pot trials revealed that the application of specific copper-based formulations CopperMancozeb, Copper hydroxide, Copper sulfate, Copper oxychloride, as well as a commercial preparation containing 1 Harpin protein, resulted in varied degrees of inhibition in the incidence of Bacterial Speck Disease, with inhibition percentages ranging from 53.3 to 86.9. The combined results of both in vitro and in vivo studies suggest that the pathogen did not develop resistance to the pesticides tested in the examined fields. The occurrence of the disease appears to be related to challenges faced by farmers in adhering to the recommended chemical dosage and application timing.

 Pseudomonas syringae pv. tomato domates bitkisinde Bakteriyel Benek Hastalığına neden olan önemli bir bakteriyel etmendir. Bu çalışma kapsamında Adana ili, Karataş ilçesinde farklı tarladan izole edilen Pseudomonas syringae pv. tomato izolatlarının bakırlı prepapatlara duyarlılık düzeyi incelenmiştir. İzolatların 30, 60 ve 90 μgml dozlarında Bakır sülfat eklenen besi yerlerinde, gelişim gösterdiği, 120 ve 150 μgml doz içeren besi yerlerinde ise gelişemediği saptanmıştır. Bu durum Karataş izolatlarının bakıra direnç geliştirmediğini göstermektedir. Ayrıca cam serada yapılan saksı denemelerinde, bazı ticari bakırlı pestisit Bakır sülfat, Bakır oksiklorür, BakırMancozeb, Bakır hidroksit ve Harpin proteini uygulamalarının Bakteriyel Benek Hastalığını 53.3-86.9 arasında değişen oranlarda baskıladığı belirlenmiştir. Her yıl bu tarlalarda hastalık görülme nedeni olarak üreticinin doğru zamanda ilaçlama yapamadığı fikri oluşmuştur.
