Generate a spray log recording precise foliar fungicide application for late blight stage in fresh-market russet potato fields during 2024 growing season

Spray Application Records *

Field Identification Details *

Variety Specific Information * Select potato variety... Russet Burbank - moderate resistance, requires intensive program Ranger Russet - good foliage resistance, tuber susceptible Umatilla Russet - partial resistance, late-season risk Alturas - processing variety with limited resistance Norkotah - fresh market highly susceptible, maximum protection needed Silverton - newer variety with improved resistance profile Chipeta - early variety requiring tight schedules Other specialty russet hybrid with unknown resistance

Disease Pressure Index * Select pressure level... High risk - optimal conditions (>70°F, >90% RH), spore detection confirmed Moderate-high - conducive weather, nearby infections reported Moderate - periodic favorable conditions, active monitoring Low-moderate - marginal conditions, preventative strategy Low risk - dry conditions, minimal pressure, standard program Post-infection salvage - active lesions present, curative rescue needed Forecast variable - weather pattern transitioning, flexible schedule

Fungicide Program Details * Choose fungicide program... Mandipropamid-based (FRAC 40) limited to 3 applications max Oxathiapiprolin (FRAC 49) high potency program Cyazofamid (FRAC 21) tank-mixed with protectant Ametoctradin + Dimethomorph (FRAC 45+40) combination therapy Fluopicolide (FRAC 43) resistance rotation sequence Traditional copper hydroxide protective schedule Mancozeb + cymoxanil limited use pattern Phosphonite salts systemic program Bio-based Bacillus subtilis preventive approach

Application Parameters *

Weather Compliance Windows * Choose weather parameters... Maximum 10mph sustained winds, 4-hour rain-free window required Calm conditions essential, inverted temperature profile detected Variable winds 5-15mph acceptable, 6-hour protection needed Early morning stable air mass, drift mitigation required Post-frontal passage - 3-hour drying time sufficient High humidity window - special label restrictions apply Heat stress conditions - temperature limitations triggered

Harvest Timing Constraints * Select PHI scenario... 3-day PHI acceptable for immediate processing 7-day PHI standard for fresh market delivery 14-day PHI - delays retail shipment schedule 30-day PHI impact on long-term storage program Storage potato timeline - PHI coordinated with binning schedule Premium early harvest - PHI blocks by price opportunity Contract delivery deadline forces alternative chemistry

Stakeholder Communication Requirements * Select communication requirement... Grocery retailer compliance - detailed residue database access required Food processor technical specification - application log sheets Crop insurance adjuster documentation - treatment verification Organic certification maintainers - National Organic Program record Export documentation - maximum residue level compliance certificates Sustainability reporting - environmental impact metrics Co-op spray operator confirmation schedules Regulatory inspector daily report format
