Asorbital formulation technology

AsorbitalTM formulation technology takes the performance of prothioconazole fungicides to the next level: with an inbuilt adjuvant which enhances uptake into the leaf, and a special solvent system which ensures the active ingredient reaches and protects every part of the leaf, ADAMA’s unique formulation consistently outperforms the market leading prothioconazole fungicide.

AsorbitalTM fungicides also boast improved levels of rainfastness, so crops remain protected for longer.

Powered by Asorbital

Comprising a unique combination of two solvents and an adjuvant to help with product uptake and distribution, ADAMA’s novel Asorbital technology was developed at our global R&D facility Neot Hovav in Israel. 

This state-of-the art facility is where ADAMA’s team of more than 100 ‘formulation mastery’ researchers and chemists develop and fine-tune new crop protection products which address the needs and challenges faced by commercial farmers around the globe.

A word from the Asorbital experts

Mel Wardle
"Our mission wasn’t simply to bring yet another generic prothioconazole fungicide to the market, but to develop an all-new formulation of this tried and tested active ingredient that offers real and tangible benefits above and beyond those already available from other prothioconazole based products.”
Mel Wardle, ADAMA’s UK fungicide product manager

Independently proven benefits

Independent laboratory trials carried out by BIOtransfer (France, 2021) have shown that the uptake of ADAMA’s AsorbitalTM formulation is quicker and more effective against septoria compared to the market leading prothioconazole product.

In the trial, a standardised amount of the test products was applied to the basal part of wheat leaves, with the apical part of the leaves left untreated. The apical part was then removed, and the basal part washed to remove any remaining active ingredient on the leaf surface. Both parts were then inoculated with septoria and incubated under saturated, humid conditions. Septoria lesion lengths were then assessed at 21 and 28 days post inoculation, with the results reflecting the quantity of active ingredient present in each part of the leaf: less disease in the basal part indicated better penetration into the leaf; less disease in the apical part indicated better migration from the basal part to the apical part.

Leaf Uptake and Migration Study wheat – Study Design

Septoria lesion lengths were assessed at 21 and 28 days post inoculation, with the results reflecting the quantity of active ingredient present in each part of the leaf:

  • Less disease in the basal part indicated better penetration into the leaf
  • Less disease in the apical part indicated better migration within the leaf

Leaf Uptake over 24 hours Efficacy against Septoria

The ADAMA formulation also offers better protection against septoria in non-treated leaf areas thanks to its superior movement within the leaf. (Source: Independent laboratory trials conducted by BIOtransfer, France)

Migration in the leaf over time Efficacy against Septoria

Longer lasting protection

Laboratory trials have also shown that the AsorbitalTM formulation offers better rainfastness than the market leading prothioconazole product.

In this trial, wheat plants were treated at the 2-3 leaf stage and subjected to 40mm of simulated rainfall at 1 or 3 hours after treatment. The plants were inoculated with septoria 24 hours later, and disease levels assessed after 21 days. In both cases, the AsorbitalTM formulation achieved better control of septoria compared to the market leading product.

Enhanced disease control

Extensive trials in the UK and Europe have shown that the improved uptake and migration of ADAMA’s AsorbitalTM formulation results in significantly better control of all target diseases compared to other prothioconazole products.

Under UK conditions, ADAMA’s AsorbitalTM formulation provides improved control of septoria, yellow rust and fusarium in wheat, with a 13% uplift in control of fusarium compared to the market leading prothioconazole product.

Enhanced disease control

ADAMA’s AsorbitalTM formulation also delivers improved control of rhynchosporium and net blotch in barley.

Safe for crops and easy to use

In addition to providing improved levels of disease control, ADAMA’s prothioconazole fungicides are also safe and easy to use: 

  • Extensive trials conducted throughout Europe have shown that the AsorbitalTM formulation has no phytotoxicity effect and is safe to use in all cereal and oilseed rape crops .
  • Good compatibility with tank mix partners makes AsorbitalTM fungicides easy to incorporate into spring and autumn spray programmes.


ADAMA’s AsorbitalTM formulation provides similar improvements against sclerotinia (+18% control) and alternaria in oilseed rape.
