Bayer Nativo Fungicide

Bayer Nativo Fungicide: Dual-Chemistry Protection for Rice, Tomato, Mango and Wheat

Fungal disease pressure rarely gives farmers advance warning — a sudden spell of humidity, and sheath blight in paddy or early blight in tomato can spread across a field within days. Bayer Nativo was built to respond to exactly this kind of situation. It brings together Tebuconazole 50% and Trifloxystrobin 25% in a single Water Dispersible Granule (WG), pairing a triazole fungicide known for its curative strength with a strobilurin known for long protectant activity.

What makes this combination practical in the field is timing flexibility. Because Tebuconazole works even after infection has begun, while Trifloxystrobin builds a protective layer for whatever comes next, Nativo doesn't demand a perfectly timed preventive spray to be effective — it still performs well when applied slightly after disease symptoms first appear, as per label recommendation.

What's Inside Nativo

How the Two Actives Divide the Work

Tebuconazole belongs to the DMI (demethylation inhibitor) group. It interferes with how fungal cells build their cell wall, which stops the pathogen from reproducing or spreading further — this is what gives Nativo its curative edge on infections already underway. Trifloxystrobin, on the other hand, works by disrupting the fungus's respiration process before infection takes hold, giving longer-lasting surface protection. Together, the product moves both systemically and mesosystemically within the leaf, so coverage isn't limited to just the sprayed surface.

Crops and Diseases It's Registered For

Application Rates by Crop

Dosage isn't uniform across diseases even within the same crop — rice, for instance, needs a different rate depending on which disease is being targeted:

A conventional knapsack or power sprayer works fine for Nativo. It's generally most effective when the spray goes on at the first visible sign of disease rather than waiting for symptoms to spread — once infection is well established across a large canopy, even a curative fungicide has more ground to cover. Waiting periods differ meaningfully by target disease, so it's worth checking the specific figure for what's being treated rather than assuming a single number applies across the board.

Where This Product Tends to Fit Well

• Paddy fields where sheath blight has historically shown up during tillering to booting stage
• Tomato crops entering a humid stretch where early blight risk is elevated
• Mango orchards managing both powdery mildew and anthracnose in the same season
• Wheat fields with a history of yellow rust pressure
• Situations calling for a fungicide with two distinct modes of action, useful where resistance management is a concern

Common Questions From Growers

Does Nativo only work as a preventive spray, or can it act after infection starts?
It does both — Tebuconazole's curative property means it can act on infections already present, while Trifloxystrobin adds protective cover against what comes next.

Why does the rice dosage change depending on the disease?
Sheath blight and blast respond well at the lower rate, while false smut and brown leaf spot are generally addressed at a higher rate with a longer pre-harvest interval — this is reflected directly on the product label.

Is one spray usually enough?
That depends on disease pressure and weather conditions during the season; repeat applications should follow label spacing guidance rather than a fixed calendar.

Can Nativo be used across more than one crop in a mixed-cropping situation?
Yes, it's registered across rice, tomato, mango, and wheat, though the dose and waiting period differ by crop and target disease.
