Benefits

Competitive Pricing
When used as a stand-alone application, RB1 can be 30–50% more cost-effective per hectare compared to other contact fungicides commonly used in CBS control programmes.

Ease of Use
The unique SL (soluble liquid) formulation ensures quick and easy mixing. RB1 is compatible with most spray oils and insecticides, making it simple to integrate into existing spray schedules.

Environmentally Friendly
RB1 is environmentally responsible and well-suited for Integrated Pest Management (IPM) programmes. It poses minimal risk to humans and does not negatively affect fish, bees, or beneficial insects.

MRL Management
RB1 supports multiple export market requirements, including the USA and South Korea. Its short withholding period enables growers to treat crops and harvest shortly thereafter—providing flexibility for managing CBS across overlapping fruiting cycles and ensuring market compliance.


How Does It Work?
RB1 achieves direct antagonism against fungal pathogens through:
- Suppression of mycelial growth.
- Inhibition of germ tube elongation.
- Malformation and prevention of conidia development.
Efficacy & Trial Data:
Multiple trials have demonstrated RB1’s strong efficacy against CBS, performing comparably to fungicides containing Mancozeb and copper-based formulations.

These results confirm that RB1 provides equivalent CBS control to conventional chemical fungicides—while offering significantly lower environmental impact and improved compatibility with IPM programmes.

RB1 is suitable for IPM programmes.
