TMTD 98% SATEC®
Active ingredient: thiram
Contact fungicide against damping off diseases
Current situation 2024
Thiram/tetramethylthiuram disulphide/TMTD, a substance with an active past, but possibly without a future? (2022)
You will still find information in our documentation about our thiram-based coatings, but they are currently not approved for use. An EU decision led to the current stop for our approvals. In February this year, the action by the active substance manufacturer against this decision was decided against at the European Court of Justice in Luxembourg. There will therefore be no come-back for this substance or plant-protection products containing thiram unless a new action leads to a positive decision. Neither the restriction of content per hectare when treating seeds (max. 20G/ha!!) nor the latest studies on groundwater contamination were accepted as a compromise. Additional studies presented at a later point during the evaluation process to evidence safe use for seed treatment were not taken into account by the commission.
The loss of thiram/TMTD now shows how important this active substance is for the seed sector.
- Thiram is an extraordinarily and widely effective fungicide against earth and seed-borne pathogens.
- As a non-systemic fungicide, thiram protects the effects of system fungicides when in combination, preventing the formation of resistances.
- It maintains and promotes seed germination, particularly if seeds need to be stored.
- Thiram is also a repellent as proven in numerous approval tests.. Thiram not only protects seeds against being eaten, it also protects birds and mammals from eating seeds treated with other substances.
To understand the value of this multi-talent, it helps to take a look at the history of thiram outside of plant protection. It has been used:
- As an excellent UV blocker in sunscreens.
- Against scabies as it has an effect on ectoparasites. This, together with the bactericide effect, means it has also been used in soaps.
- In therapy for alcoholics, but then replaced by the similar substance TETD (tetraethylthiuram disulphide). Latest studies on the latter now show an effect against certain types of cancer.
- As a vulcanisation accelerator in the rubber industry.
Back in hospitals??
Thiram/tetramethylthiuram disulphide/TMTD and Disulfiram/tetraethylthiuram disulhphide/TETD are classified in various studies as antibacterial products against multi-resistant hospital germs such as Staphylococcus aureus strains. Work is currently under way to introduce a combination therapy with disulfiram.
Why are radical decisions so short-sighted?
After seeing the effects of the Russian war on the Ukraine regarding agriculture in Europe, and globally, it is hoped that well-known substances will again be considered and evaluated to see if their benefits under specific conditions are still greater than any eventual damage, particularly when they are used as seed coatings – if applied precisely using extremely low quantities.
