Sažetak

In the production of ornamental plants, it is often necessary to combine plant protection products (PPPs) for simultaneous pest control. The use of a combination of PPPs often leads to phytotoxicity. The aim of this study was to determine the phytotoxicity of the combination of fungicides (azoxystrobin and cyprodinil + fludioxonil) and insecticides based on abamectin and thiomethoxam on the ornamental plant Petunia sp. The PPPs are used at recommended and double doses. Based on the damage, phytotoxicity indices were calculated. Petunia plants are sensitive even when PPPs are used in recommended doses. Combinations of the both insecticides with the combined fungicide based on cyprodinil and fludioxinil can be advised to protect petunias only if one applies the recommended doses. All combinations of insecticides with a fungicide based on azoxystrobin should not be applied because there is a serious risk of phytotoxicity.
