(Family: Solanaceae) were studied. The fungicide was applied to tomatoes grown in greenhouse conditions at the dosage (400 ml/100 l water) recommended by the manufacturing company and double the recommended dosage (800 ml/100 l water). All dosages of the fungicide Agri Fos 400 caused various abnormalities in meiosis when compared with the control. This situation could lead to a decrease in the productivity of fruits.

Bu fungisit, sera koşullarında yetiştirilen domates bitkilerine üretici firmaca önerilen dozda (400 ml/100 l suya) ve önerilenin iki katı (800 ml/100 l suya) dozunda uygulanmıştır. Agri Fos 400 fungisitinin uygulanan tüm dozları kontrole göre polen mayozunda çeşitli anomalilere neden olmuştur. Bu durum meyve veriminde bir azalmaya yol açabilir.
