Tenet®

Bio-fungicide granule for Onion White Rot and Fusarium basal rot

What is it and how does it work?

Tenet is abio-fungicide granule, developed in partnership with Lincoln University to mitigate against Onion White Rot.

Tenet utilises an internationally recognised strain(LU132)of endophytic Trichoderma. This strain of Trichoderma atroviride was isolated from a Pukekohe onion paddock in the 1980s and is active against a wide range of fungal pathogens.

This granular formulation proved the most effective application method through extensive testing through Australia and New Zealand and led Tenet to become the first registered biocontrol agent for onion white rot in New Zealand.

Tenet is best used as part of an integrated approach dependent on the likely infection levels in the paddock.

The strain of Trichoderma is applied with the seed at planting. As the seed germinates, the Trichoderma aggressively colnises the root zone, protecting the plant’s roots from fungal pathogens including Sclerotium cepivorum and Fusarium oxysporum.

By reducing the effect of disease, the Trichoderma also helps to improve germination and establishment.

Key Benefits

Trial Results

Onion White Rot Control

Field trials conducted on spring onions showed that Tenet granule used at planting reduced onion white rot disease by 50% compared to an untreated control and Tenet + 1 fungicide application reduced disease by 75% compared to the untreated control.

Improved Emergence

Tenet trials have repeatedly demonstrated improved seedling emergence. Optimum early plant growth affords the opportunity for increased crop yields of up to 10% with Tenet use.

Increased bulb weights
