Efficacy of T34 Biocontrol® in Cucurbit Crops
The official trials of T34 Biocontrol® in cucurbits,
compared against reference chemical treatments.
See the evidence for yourself.
- 25 official GEP trials in Spain, Italy, and France
- Always benchmarked against the reference chemical treatment
- Experimental design, dosage rates, varieties, and statistical significance
Being sustainable isn’t enough. It has to be effective.
A professional grower cannot afford to lose productivity in exchange for adopting a more sustainable solution. If a product doesn’t control the disease, nothing else matters.
That’s why T34 Biocontrol® doesn’t rely on its biological origin as an argument. It demonstrates that it performs under real production conditions and holds up against what growers are already applying.
Preserving soil biological activity, reducing residue-related constraints, and moving toward safer protocols only make sense if yield is maintained.
We’re not asking you to simply trust that a biological can work. We show you the trials — their design and their results.

Authorized crops and pathogens, as well as the maximum number of applications, vary by country. Always check the current registration status and the approved label before applying.
What kind of evidence you'll find in the dossier
Trials conducted under GEP protocol, evaluated by accredited independent companies, and submitted to the competent authorities. These are not in-house tests.

-
Six outdoor GEP trials were conducted in melon, with a prior nursery application and three dosage rates evaluated against a reference chemical treatment and an untreated control. The dossier presents the reduction in incidence for each dosage rate, along with the marketable yield obtained with each treatment.
-
The Didymella spp. trials in cucumber evaluated all three plant organs separately. The dossier includes an independent chart for leaf, stem, and fruit, showing the three dosage rates tested and the results obtained on each organ compared with the reference chemical treatment.
-
Each trial reports the incidence recorded in the untreated control, allowing the percentage reductions to be interpreted in the context of actual disease pressure. Both the Pythium spp. trials in cucumber and the Didymella spp. fruit trials were conducted under high disease pressure, not under low-incidence conditions.
-
Each chart includes the statistical grouping letters for every treatment, allowing you to identify which treatments show statistically significant differences and to compare each dosage rate with the reference chemical treatment.
-
Each trial includes a full experimental design sheet: variety, location, number of blocks and replicates, plot size, trial duration, planting density, and application volume. This information lets you assess how comparable the trial conditions are to those on your own operation.
-
The dossier closes with a study conducted in organic greenhouse zucchini in El Ejido (Almería), comparing two greenhouses on the same operation. It documents plant losses during establishment, replacement costs, and the weekly harvest progression in both greenhouses through the end of the cycle.
All the answers are in the dossier. With the trial, evaluating center, and conditions for each one, so you can compare them against your own growing conditions.
A dossier for every crop
Each crop has its own technical dossier, with the official trials, scientific publications, and application protocol that apply to it. This is the complete series.
