Potatoes are one of the most widely consumed vegetables globally, yet they remain highly vulnerable to diseases such as late blight (Phytophthora infestans), black scurf (Rhizoctonia solani), and early blight (Alternaria solani), as well as pests like the Colorado potato beetle (Leptinotarsa decemlineata) and wireworms (larvae of Elateridae beetles). According to the Food and Agriculture Organization (FAO), global potato production losses due to pests and diseases can exceed 30-40% annually, with additional post-harvest losses during storage.
The Science Behind the New Protection System
Researchers at Novgorod State University’s Chemical-Technological Institute have designed a phase-specific integrated protection system that applies the most effective approved treatments at each growth stage.
- Pre-Planting Soil Treatment
- Application of Pecilomycin PM116 targets soil-dwelling pests like wireworms and May beetle larvae.
- Seed treatment with Vibrance Top protects mother tubers and sprouts from fungal and bacterial infections.
- Vegetative Growth Phase
- Phosphonin Flo (a micronutrient fertilizer) reduces nutrient stress and enhances fungicidal action.
- Shirlan SC combats foliar diseases (late blight, early blight) and controls pests like the Colorado potato beetle.
- Flowering & Final Growth Stages
- Azotobacter vinelandii AV 42 (a biostimulant) suppresses powdery mildew and stimulates growth.
- Desiccation with Reglon or Shirlan SC prevents spore accumulation before harvest.
Field Results & Scalability
Trials in Novgorod Oblast demonstrated a 25% yield increase with optimized planting techniques (75 cm row spacing, 28 cm ridge height). Companion planting with lupine also reduced aphid infestations while enriching soil nitrogen.
This integrated protection system offers a sustainable, scalable solution for potato farmers, reducing chemical use while maximizing yields. By tailoring treatments to regional pest pressures, it can be adapted across Russia and beyond.
