Look to Aprovia Top for: Two modes of action to protect against apple scab and powdery mildew Protective and early curative activity against apple scab The translaminar activity of difenoconazole protects against disease by inhibiting the growth of mycelia. Difenoconazole is absorbed rapidly by the leaf and moves quickly from one side of the leaf to the other, protecting both leaf surfaces and providing excellent rainfastness. Solatenol moves quickly into the waxy layer of leaves. It slowly moves from the waxy layer into leaf tissue over time providing a constant level of disease control between sprays. Together, Solatenol and difenoconazole interact to provide broad-spectrum control in apples. Active ingredients: Solatenol (Group 7) Potent SDHI Difenoconaxole (Group 3) Another line of defense Metabolizes slowly for residual protection No known resistance to apple scab or powdery mildew Application rate: Aprovia Top is registered at very low use rates, ranging from 156 ml/ac to 260 ml/ac
Long-lasting activity against leaf and fruit scab Even under heavy scab pressure, Aprovia Top provides excellent preventive protection. Aprovia Top is a translaminar fungicide; it penetrates the leaf to provide protection on both sides. In addition, Aprovia Top sticks very well to the leaf surface, making it very rainfast. Preventive activity against disease Aprovia Top acts quickly, targeting disease spores before they can germinate on leaves. Untreated Treated with Aprovia Top Day 1 Healthy spore on apple leaf surface Day 5 Spore has germinated, hyphae grows Day 1 Dead spore on leaf surface treated with Aprovia Top Day 5 Spore is dead on leaf treated with Aprovia Top Early curative activity When applied preventively, Aprovia Top protects against spore germination and direct infection. Once the leaves or fruit become infected, Aprovia Top can stop mycelial growth but not control lesions that are already present.

Application information Disease Rate Application timing Additional information Scab (Venturia inaequalis and V. pyrina) 386 643 ml/ha (156 260 ml /ac) Protective spray schedule: Apply every 7 10 days starting at ¼ ½" green tip or when environmental conditions become conducive for scab. Continue through petal fall until the threat of primary scab is complete. Forecasting spray schedule: Use a forecasting system beginning at green tip. Apply within 48 hours of the onset of an infection period. Apply a follow-up spray after seven days. If disease pressure is high, use the highest rate. For improved scab control, tank-mix Aprovia Top with a protectant fungicide registered for the disease.
