Tomato producers in the Karacabey district of Bursa are experiencing significant yield losses caused by pesticide residues in irrigation water. The contamination occurs when agricultural runoff from rice fields in the Manyas and Gönen regions mixes with water supplied from Manyas Lake.

Local farmers and the Karacabey Chamber of Agriculture have noted developmental issues in crops, such as leaf curling. Yield discrepancies between areas using contaminated water and those using artesian water are reported to be as high as 5 to 7 tons per decare. To mitigate the crisis, officials and producers are requesting government intervention to separate rice field drainage from irrigation channels or to provide clean water directly from the Manyas Dam.
