Premier Fungicide Portfolio and Active Chemistries
Corteva's fungicide portfolio features research-driven active molecules covering diverse chemical families, including strobilurins, cyanoacetamide oximes, oxazolidinediones, and inorganic copper formulations.
Each formulation is engineered for specific disease targets, delivering protective coverage, acropetal vascular mobility, or vapor-phase redistribution across dense crop canopies.
- Galileo: Picoxystrobin 22.5% SC (Strobilurin / QoI class for sheath blight, rusts, and leaf spots)
- Equation Pro: Famoxadone 16.6% + Cymoxanil 22.1% SC (Dual-action synergy for late blight and downy mildew)
- Curzate M8: Cymoxanil 8% + Mancozeb 64% WP (Systemic and multi-site contact combination for blights)
- Kocide 3000: Copper Hydroxide 46.1% DF (Bio-active bio-protective copper bactericide and fungicide)
Target Disease Spectrum Across Crops
Corteva fungicides are approved by CIBRC across staple cereals, commercial cash crops, and high-value fruit and vegetable crops.
Applied preventively or upon early infection onset, these chemistries halt spore germination, disrupt fungal cellular respiration, and stop secondary spread throughout the field.
- Paddy (Rice): Sheath blight (*Rhizoctonia solani*) and blast (*Magnaporthe oryzae*) control with Galileo
- Potato & Tomato: Late blight (*Phytophthora infestans*) curative control with Equation Pro and Curzate M8
- Grapes: Downy mildew and anthracnose management using copper and oxime formulations
- Chilli & Spices: Anthracnose fruit rot, powdery mildew, and bacterial leaf spot suppression
Anti-Resistance Management and Application Best Practices
To prevent pathogen strains from evolving resistance against single-site strobilurins or oximes, Corteva emphasizes disciplined FRAC resistance management.
Growers should alternate single-site systemic fungicides with multi-site contact protectants like Mancozeb or Kocide copper hydroxide, limiting single-class applications to recommended seasonal thresholds.
- FRAC rotation: Alternate FRAC Group 11 (Strobilurins) with Group 27 (Cymoxanil) and Group M (Multi-site)
- Preventive application: Spray before disease lesions reach epidemic levels for maximum curative efficacy
- Water volume: Calibrate sprayers to deliver 500 liters per hectare for thorough foliage coverage
- Personal protection: Wear nitrile rubber gloves, face shield, and protective apron during tank mixing

Common questions
What makes Equation Pro effective against potato late blight?
Equation Pro combines Famoxadone (protects leaf surfaces and prevents spore germination) with Cymoxanil (penetrates tissue rapidly to provide curative kickback activity).
Why is Kocide 3000 preferred over traditional copper oxychloride?
Kocide 3000 features fine bio-active copper hydroxide dry flowable (DF) granules that release bio-available cupric ions efficiently at lower metallic copper load per hectare.
Can Galileo fungicide be sprayed in standing rice crops during flowering?
Yes, Galileo (Picoxystrobin 22.5% SC) is registered for rice sheath blight; apply during tillering to panicle initiation following label pre-harvest intervals.
