Do not mix with oil-based formulations or apply to crops previously treated with oil-based formulations as this would hinder the product's penetration. Caution is advised when mixing with products containing carbonate or bicarbonate due to potential carbon dioxide and/or foam formation. It is not recommended to mix with sulfur-based products in vineyards where frequent manual labor is expected after treatments.", "phytotoxicity_constraints": "On Corvina, Corvinone, Garganega, Malvasia, Molinara, Rondinella, Schiava and other local grapevine varieties, conduct preliminary tests on a few plants before extending treatments to the entire vineyard, especially when mixed with other products.", "environmental_restrictions": "Very toxic to aquatic life with long lasting effects. Do not contaminate water with the product or its container. Do not clean application equipment near surface water. Avoid contamination via drainage systems from farms and roads.", "buffer_zone_requirements": "For apple and pear: apply a 25-meter buffer strip from surface water bodies; or a 20-meter buffer strip combined with 30% drift-reducing nozzles; or a 20-meter buffer strip combined with treating the last row from outside to inside with an additional 35% drift reduction. For grapevine: apply a 20-meter untreated vegetated buffer strip from surface water bodies; alternatively, apply a 5-meter untreated vegetated buffer strip combined with devices that reduce drift by 95%.", "resistance_management_summary": "To avoid or delay the onset of resistance, adhere to the label instructions and apply DELAN PRO preventively.", "application_recommendations": "Use spray volumes that ensure complete and uniform coverage, avoiding runoff from vegetation. For control of scab, brown spot, alternaria, anthracnose, and powdery mildew on pome fruit, apply from bud break until the beginning of fruit ripening. For phomopsis control on grapevine, apply from bud burst to unfolded leaves. For downy mildew and black rot control on grapevine, apply from the unfolded leaves stage.", "safety_notes": "Wear protective gloves/clothing and eye/face protection. Avoid breathing aerosols. During mixing and loading, wear work overalls/clothing, suitable gloves, and eye/face protection. Wear work overalls/clothing and suitable gloves during application and re-entry work. Do not re-enter the treated area until the vegetation is completely dry. Allow at least 48 hours for re-entry into the vineyard.", "retrieval_summary": "DELAN PRO is a mixed contact and systemic fungicide containing dithianon (FRAC M09) and potassium phosphonate (FRAC P07). It is registered for use on apple, pear, and grapevine to control a range of diseases including scab, brown spot, alternaria, anthracnose, powdery mildew, downy mildew, phomopsis, and black rot. The product acts preventively, protecting existing foliage by contact and new growth through systemic action, which also stimulates the plant's natural defenses. It is suitable for use under high disease pressure. Key constraints include a 48-hour re-entry interval for grapevine, specific buffer zones for pome fruit (20-25m) and grapevine (5-20m) to protect aquatic organisms, and incompatibility with oil-based products and nitrogenous foliar fertilizers. Phytotoxicity tests are recommended for certain local grapevine varieties.", "situation_fit_summary": "This is a mixed contact and systemic fungicide offering both a protective surface barrier and internal protection. Its systemic component is mobile within the plant, protecting new growth and stimulating natural defenses, making it highly effective during periods of active vegetation expansion. The product is designed for preventive use, establishing protection before infection events. It is well-suited for high-pressure situations with heavy rainfall or rapid growth, where its dual action provides robust protection against both oomycete and ascomycete pathogens. The multi-site contact component contributes to a strong anti-resistance strategy.", "uses": [ { "crop": "apple", "disease": "scab", "setting": "", "dose_min": 2.5, "dose_max": 2.5, "dose_unit": "l/ha", "concentration_min": 0.17, "concentration_max": 0.17, "concentration_unit": "l/hl", "treatment_interval_min_days": 5, "treatment_interval_max_days": 10, "max_treatments_per_season": 6, "pre_harvest_interval_days": 35, "spray_volume_min": 200.0, "spray_volume_max": 1500.0, "growth_stage_start": "bud break", "growth_stage_end": "beginning of fruit ripening" }, { "crop": "apple", "disease": "alternaria", "setting": "", "dose_min": 2.5, "dose_max": 2.5, "dose_unit": "l/ha", "concentration_min": 0.17, "concentration_max": 0.17, "concentration_unit": "l/hl", "treatment_interval_min_days": 5, "treatment_interval_max_days": 10, "max_treatments_per_season": 6, "pre_harvest_interval_days": 35, "spray_volume_min": 200.0, "spray_volume_max": 1500.0, "growth_stage_start": "bud break", "growth_stage_end": "beginning of fruit ripening" }, { "crop": "apple", "disease": "anthracnose", "setting": "", "dose_min": 2.5, "dose_max": 2.5, "dose_unit": "l/ha", "concentration_min": 0.17, "concentration_max": 0.17, "concentration_unit": "l/hl", "treatment_interval_min_days": 5, "treatment_interval_max_days": 10, "max_treatments_per_season": 6, "pre_harvest_interval_days": 35, "spray_volume_min": 200.0, "spray_volume_max": 1500.0, "growth_stage_start": "bud break", "growth_stage_end": "beginning of fruit ripening" }, { "crop": "apple", "disease": "powdery mildew", "setting": "", "dose_min": 2.5, "dose_max": 2.5, "dose_unit": "l/ha", "concentration_min": 0.17, "concentration_max": 0.17, "concentration_unit": "l/hl", "treatment_interval_min_days": 5, "treatment_interval_max_days": 10, "max_treatments_per_season": 6, "pre_harvest_interval_days": 35, "spray_volume_min": 200.0, "spray_volume_max": 1500.0, "growth_stage_start": "bud break", "growth_stage_end": "beginning of fruit ripening" }, { "crop": "pear", "disease": "scab", "setting": "", "dose_min": 2.5, "dose_max": 2.5, "dose_unit": "l/ha", "concentration_min": 0.17, "concentration_max": 0.17, "concentration_unit": "l/hl", "treatment_interval_min_days": 5, "treatment_interval_max_days": 10, "max_treatments_per_season": 6, "pre_harvest_interval_days": 35, "spray_volume_min": 200.0, "spray_volume_max": 1500.0, "growth_stage_start": "bud break", "growth_stage_end": "beginning of fruit ripening" }, { "crop": "pear", "disease": "brown spot", "setting": "", "dose_min": 2.5, "dose_max": 2.5, "dose_unit": "l/ha", "concentration_min": 0.17, "concentration_max": 0.17, "concentration_unit": "l/hl", "treatment_interval_min_days": 5, "treatment_interval_max_days": 10, "max_treatments_per_season": 6, "pre_harvest_interval_days": 35, "spray_volume_min": 200.0, "spray_volume_max": 1500.0, "growth_stage_start": "bud break", "growth_stage_end": "beginning of fruit ripening" }, { "crop": "grapevine", "disease": "phomopsis (dead-arm)", "setting": "", "dose_min": 3.0, "dose_max": 3.0, "dose_unit": "l/ha", "concentration_min": 1.0, "concentration_max": 1.0, "concentration_unit": "l/hl", "treatment_interval_min_days": 7, "treatment_interval_max_days": 7, "max_treatments_per_season": 2, "pre_harvest_interval_days": 42, "spray_volume_min": 150.0, "spray_volume_max": 300.0, "growth_stage_start": "bud burst", "growth_stage_end": "unfolded leaves" }, { "crop": "grapevine", "disease": "downy mildew", "setting": "", "dose_min": 3.0, "dose_max": 4.0, "dose_unit": "l/ha", "concentration_min": 0.3, "concentration_max": 0.4, "concentration_unit": "l/hl", "treatment_interval_min_days": 10, "treatment_interval_max_days": 14, "max_treatments_per_season": 4, "pre_harvest_interval_days": 42, "spray_volume_min": 200.0, "spray_volume_max": 1000.0, "growth_stage_start": "unfolded leaves", "growth_stage_end": "" }, { "crop": "grapevine", "disease": "black rot", "setting": "", "dose_min": 3.0, "dose_max": 4.0, "dose_unit": "l/ha", "concentration_min": 0.3, "concentration_max": 0.4, "concentration_unit": "l/hl", "treatment_interval_min_days": 10, "treatment_interval_max_days": 14, "max_treatments_per_season": 4, "pre_harvest_interval_days": 42, "spray_volume_min": 200.0, "spray_volume_max": 1000.0, "growth_stage_start": "unfolded leaves", "growth_stage_end": "" } ], "low_confidence_fields": [], "extraction_notes": "", "reviewed": false, "source_label_version": "20.04.2026", "source_file": "DELAN-PRO.pdf", "last_update": "17/08/2026" }
