Test results: The IDTA in facts and figures.

Field tests

Deposition in winter wheat (Syngenta)

Trial was conducted in winter wheat, growth stage 37 (BBCH). The tracer was Helios 500 SC. Whole plants were taken after spraying and cut into 3 sections:

  • Upper third (upper leafs)
  • Middle part
  • Lower third


Nozzle comparison in winter wheat, BBCH 37 with different speeds and application rates


Deposition of IDTA 120-025C/05C compared with ID 120-025/05

Deposition of IDTA 120-025C/05C compared with ID 120-025/05

IDTA achieves up to 17 % better overall deposition compared with ID3.

IDTA achieves up to 50 % higher deposition in  the upper third compared with ID3.

Field test with vertical target surfaces

Field test was conducted with an Amazone sprayer UF 1201 equipped with a 15 m boom to investigate deposition on vertical target surfaces. Deposition on the front and back sides was analyzed for different nozzle types and forward speeds. Evaluation of the water-sensitive paper was performed with “DepositScan”.

Meteorological conditions:

  • Rel. humidity 50 %
  • Temperature 23 °C
  • No wind

IDTA air injector double flat fan nozzles achieve significant better deposition on vertical target surfaces compared with an standard air-injector flat spray nozzle (ID3). The nozzles provide up to 3 times better coverage in travel direction.

IDTA in combination with other nozzles

Combinations (JKI approvals pending)

Comparison with air-injector flat spray nozzle (ID3) on vertical target surface

Mixed setting in the center of the boom with IDTA and ID3 to avoid spraying onto frame and other parts of the sprayer.

Double total coverage

Border spraying of IDTA with IS 80 possible thanks to same effective spray width of the two patterns of IDTA.

Significantly higher deposition on target to the front and back


More uniform coverage to the front and back
