Infinito Fungicide — powerful protection against late blight & downy mildews

Introduction of Infinito Fungicide

Late blight and downy mildew can wipe out entire fields in a single season. Bayer’s Infinito® fungicide is a go-to product for many growers because it combines two complementary active ingredients for fast, long-lasting control and resistance management. Below is a clear, farmer-friendly guide to what Infinito contains, how it’s used, recommended doses (including per-litre guidance), and the benefits you can expect.

What is Infinito? (technical name & content)

Infinito is a suspension concentrate (SC) that contains  Fluopicolide 62.5 + Propamocarb Hydrochloride 625 SC (5.56% w/w + 55.6% w/w) as the active ingredients. This dual-AI formulation gives both rapid activity and good residual protection, plus two different modes of action to help manage resistance. 

How Infinito works (short)

Fluopicolide — a fast-acting systemic that targets oomycete pathogens’ mobility and infection structures, providing vigorous curative and antisporulant activity.

Propamocarb HCl — a proven systemic/contact oomyceticide that acts preventively and protects new growth.
Together, they give both immediate disease knock-down and ongoing protection, making Infinito especially effective against late blight (Phytophthora infestans) and several downy mildews.

Recommended dosage (hectare and per-litre guidance)

Label recommendations vary slightly by crop and region, so always follow the local product label. Typical guidelines used widely are:

• General field rate: 1.2–1.6 L/ha (some regional labels and supplier pages show 1.25–1.5 L/ha). Apply on a 7–10 day interval under high disease pressure, or 10–15 days when pressure is lower. 
• Water volume & per-litre dilution: If using ~500 L water/ha (a common ground-sprayer volume), 1.25–1.6 L/ha equates to roughly 2.5–3.2 ml of Infinito per litre of spray (1.25 L ÷ 500 L = 2.5 ml/L; 1.6 L ÷ 500 L = 3.2 ml/L). Some foliar-spray recommendations used by dealers report ~2 ml/L for lighter water volumes or lower pressure situations — but that is a lower rate and growers should adjust by label/crop. Always calculate ml/L from your chosen L/ha and actual spray volume. 

Practical examples:

On potato (late blight): 1.25–1.6 L/ha in 400–600 L water; repeat every 7–10 days when blight risk is high. Pre-harvest interval (PHI) can vary by label — some regional labels list 7–19 days (Bayer India product pages indicate a 19-day PHI for certain uses), so check the label for your market. 

For vegetables (downy mildew) such as cucumber or brassicas, follow crop-specific label rates (often within the 1.2–1.6 L/ha range) and the stated waiting periods.

How to apply (best practice)

• Start applications preventively when conditions favour disease (cool, wet weather) or at the first sign of infection.
• Maintain good spray coverage — Infinito is rainfast and works well in IPM programs, but thorough coverage improves control.
• Rotate modes of action: because Infinito combines two AIs, use it as part of a rotation program and avoid excessive consecutive applications to reduce resistance risk. Label guidance typically limits the number of consecutive applications. 

Uses (which diseases & crops)

Infinito is specifically formulated to control late blight in potato and downy mildews across a range of vegetable and field crops. It’s also labelled for white blister in brassica vegetables in some markets. Its label and product literature highlight its role in blight/mildew programs where both curative and preventive action are needed.

Infinito Fungicide: Key benefits

• High efficacy against late blight and downy mildew — vigorous curative and antisporulant activity. 
• Two active ingredients, two modes of action — improved resistance management compared with single-AI products. 
• Good rainfastness and systemic activity — fits into IPM and irrigation programs; protects new growth. 
• Flexible use in several crops — labelled uses for potatoes, cucurbits, brassicas and other vegetables depending on region. 

Safety, residues & label compliance

Always read and follow the local product label and SDS. The label will state the maximum number of applications, pre-harvest interval (PHI) for each crop, personal protective equipment, and environmental precautions. Residues and PHI vary by market — for example, some regional Bayer labels list a 19-day PHI for potato, while other labels may differ. Use only the formulation sold in your country and follow label limits. 

Final takeaways

Bayer Infinito Fungicide offers a strong, dual-action tool for growers battling late blight and downy mildews. Its combination of fluopicolide + propamocarb HCl delivers rapid knockdown and lasting protection, and label-recommended rates (generally ~1.2–1.6 L/ha, which equals about 2.5–3.2 ml/L in a 500 L/ha spray volume) make it straightforward to dose. As always, use Infinito as part of an integrated disease-management plan — follow the label, rotate chemistries, and optimise spray coverage for best results.
