BBCH Stages - Apples - Germany by Boris Martin Tangoa Mesia https://padlet.com/ringotangoa/6kwhhko3ejditvz4 en-us 2021-07-11 19:05:05 UTC 2023-02-21 04:09:03 UTC hello@padlet.com https://padlet.net/icons/png/1f34e.png BBCH Stages ringotangoa https://padlet.com/ringotangoa/6kwhhko3ejditvz4/wish/1644677152 This padlet follows the development of Malus domestica tres at University of Hohenheim, Stuttgart. Shown pictures were taken between April 19th – July 5th, 2021.

BBA (2001), Growth stages of mono-and dicotyledonous plants: BBCH Monograph, was used for BBCH stages identification.

Kelderer et al. (2016) evaluated the effect of different methods for the control of woolly apple aphid in organic apple growing.

·       Spray applications of Polithiol, an emulsifiable suspension containing 400 g/L paraffin oil (CAS N.97862-82-3) as active substance and 5-10% w/w sulphur, 1 in late autumn and 1 in early spring significantly reduced E. lanigerum infestation. One application of the product in spring was also effective to control this pest
·       A single application of slaked slime in autumn showed to be ineffective for control.
·       Intensive pruning combined with anti-hail netting increased woolly aphid infestations. Long pruning (as few cuts as possible, weak growth stimulation) showed lower infestation levels but percent infested shoot length values remained high.
·       Reduced infestation levels were found in rootstocks of Geneva G11 and G41, and M9 Pajam 2.
