The results for 2010 are summarised in Table 3.
The height of corn plants was generally significantly
reduced (in the range of 25–125 cm) by the application
of CCC (305 g/l) + ethephon (155 g/l) and
ethephon (480 g/l) depending on the preparation
used and time of application. Ethephon 576 g a.i./ha
in BBCH 18–19 reached a height reduction of about
46 cm, CCC 458 + ethephon 233 g a.i./ha in BBCH
18–19 height reduction of about 25 cm, ethephon
2 × 576 g a.i./ha in BBCH 18–19 and 34–36 height
reduction of about 125 cm, CCC 2 × 458 + ethephon
2 × 233 g a.i./ha in BBCH 18–19 and 34–36 height
reduction of about 89 cm, ethephon 576 g a.i./ha in
BBCH 34–36 height reduction of about 96 cm, CCC
458 + ethephon 233 g a.i./ha in BBCH 34–36 height
reduction of about 67 cm compared to control.
