Hello and welcome to the BarthHaas HopUpdate July 2023!
Weather conditions and Plant Development Germany
Since the last HopUpdate in June and July, consistently summery temperatures with up to 36°C in all German growing regions. Only individual, locally limited precipitation. The precipitation amounts for June and July are significantly below the long-term average. The soil conditions are correspondingly dry. The lack of water is clearly visible in the hops, and sides shoots building is severely restricted. The bines are very slender and pointed. Accordingly, all varieties are currently rated as below average to severely below average.
The stage of development is now up to one week ahead of the long-term average. The hop fields currently have a BBCH stage of 51 to 55, according to which the inflorescence buds are visible to enlarged. In addition, BBCH stage 61 to 65 can be found across all varieties, which indicates the beginning of blooming or full blooming.
The primary infection with downy milldew was successfully controlled. Currently, there is no risk of infection by downy mildew. Powdery mildew is increasingly found especially in susceptible varieties such as Herkules. Infestation with aphid and red spider mite is under control.
