| The post-infection activity of hydrated lime against conidia of Venturia inaequalis was evaluated using an in vitro test system based on isolated apple leaf cuticles. Experiments were conducted at 20°C and treatments were applied 24 or 48 h after inoculation. Experiments were assessed by counting living primary stromata 72 h after inoculation using fluorescence microscopy and fluorescein diacetate (FDA) as a vital stain. At the conditions of the in vitro test system hydrated lime had a post-infection activity. Suspension of 5 g l-1 applied 24 h after inoculation (16 h after infection) killed all primary stromata and stopped their further development. Treatments 48 h after inoculation reduced the number of vital primary stromata to 60% of control.... |

| The post-infection activity of copper hydroxide and copper sulfate against conidia of Venturia inaequalis were evaluated using an in vitro test system based on isolated apple leaf cuticles. Experiments were conducted at 20°C and treatments were applied 24 or 48 h after inoculation. Experiments were assessed by counting living primary stromata 72 h after inoculation using fluorescence microscopy and fluorescein diacetate (FDA) as a vital stain. Copper hydroxide and copper sulfate showed post-infection activity and killed primary stromata, provided the surface of the CM was kept wet. Copper hydroxide was more effective than copper sulfate and was able to kill all primary stromata 24 h after inoculation at concentrations of 116 and 231 mg l-1. Results... |
