Active substance reduction & market pressure over growers
The most widely used active substances for Rhizoctonia solani control in potato cultivation are currently under European Commission scrutiny for per- and polyfluoroalkyl substances (PFAS) as degradation products, and their long-term effects on soil and water quality.
Being prepared means having alternatives that match their efficacy on controlling disease. And if those alternatives also deliver better marketable yield and improve soil health season after season — here is how modern biotechnology makes it possible, backed by scientific evidence and field data.

ROOTED IN SCIENCE
More then 20 years of research in biological control agents for plant protection
More than 25 years ago, Emeritus Professor Dr. María Isabel Trillas at the Universitat de Barcelona identified an exceptional strain of Trichoderma asperellum: highly effective, adaptable to different crops and conditions, active against multiple soil-borne pathogens, and capable of working through different application strategies. That strain, now patented and registered as T. asperellum strain T34, became the scientific foundation of Biocontrol Technologies.
What began as scientific research soon proved to have a much broader value. T34 was not a microorganism to remain confined to the laboratory: over years of trials, crops and field conditions, it continued to demonstrate its potential as a practical biological tool for modern crop protection.
Today, the Chair of Microorganisms in Agriculture — a joint initiative of Biocontrol Technologies and the University of Barcelona maintains this commitment to applied research.
RootDei Biocontrol®
RootDei Biocontrol® is the result of that journey applied to potato production: a specific formulation and use strategy designed for potato growers, focused on Rhizoctonia solani control and developed to integrate easily into standard planting systems — without changing machinery or adding complexity to the grower’s routine.
It brings together what growers need today: reliable disease control, compatibility with sustainable production, support for soil and root health, and a practical way to protect yield and quality in a changing regulatory context.

TECHNICAL SPECIFICATIONS
A highly concentrated formulation with one powerfull strain
RootDei Biocontrol® is applied once to the planting furrow during sowing . The product integrates seamlessly into standard planting processes—without additional steps or machine changes. Colonization of the rhizosphere by T. asperellum T34 protects the plant during the critical phase of tuber development.

Easy integration into existing cultivation processes
RootDei Biocontrol® is designed to integrate naturally into standard potato farming practices. The primary application method requires no additional machinery or steps.
In-furrow application
A single application at sowing – directly into the planting line, at the same time as planting the tubers.
No additional treatments are required during the entire harvest cycle. Protects roots and stolons from the very beginning of tuber development.

In Process of Registration
Roller Table
Apply evenly to the tuber surface before planting. A proven method with excellent results in field trials.
Note on alternative application methods:
Roller table and irrigation application methods go beyond the scope of the officially approved label in Germany (BVL 00A933-00). Application is the sole responsibility of the user. Please observe the valid authorization and national plant protection regulations. Alternative application methods have been tested and are currently undergoing the approval process.
Multiple Mechanisms of Action.
Trichoderma asperellum strain T34 works through a network of mechanisms that not only combat pathogens but also promote plant health. The FRAC classifies T34 under group BM02 — a multi-mode microbial control product that prevents the development of resistance.
FRAC BM02
Trichoderma asperellum strain T34 is classified under FRAC group BM02 — microbial agents with multiple simultaneous modes of action.
Resistance development in Rhizoctonia solani or among other diseases would require simultaneous mutations against all — evolutionarily near-impossible. Efficacy remains stable across multiple growing seasons.

Stem Canker and Black Scurf
Black scab and stem canker in potatoes — the most important soil-borne disease in potato cultivation in temperate climates.
Economic impacts are both quantitative (yield loss) and qualitative (tuber quality, marketability).
Active trials in Germany and across Europe
The efficacy and safety of RootDei Biocontrol® has been confirmed in official trials according to Good Experimental Practice (GEP) — the strictest standard for the approval of plant protection products in the EU.
