Healthy Garden - Weihenstephan Day of Leisure Horticulture

This year's Leisure Horticulture Day, which is aimed at ambitious amateur gardeners and members of horticultural associations, focussed on the topic from various angles.

Benefit insects - protect plants

Patience and a good ability to observe the plant population are a prerequisite for reacting to plant protection problems in good time. The promotion of beneficial insects or their targeted use can help with control. However, certain basic principles must be observed. Which pest is involved so that the right antagonist can be found. What are the optimum conditions for my beneficial insect?

Box tree moth in focus: „Mission impossible“?

Based on the film series with information on the target object, tactical analysis and an action matrix, the serious threat to the box tree from the box tree moth and other diseases (e.g. box tree dieback, box tree spider mite) was highlighted. Without early and consistent measures, the caterpillars will devour entire stands of plants within a few weeks. Examples range from mechanical measures (e.g. rinsing with a pressure washer) to the use of nematodes.

Listen what's coming in from outside? - Introduced pests in fruit growing

Due to globalisation, international trade and private travel, „stowaways“ are increasingly finding their way to us. Climatic changes also contribute to these invasive species gaining a foothold in our country and multiplying unchecked. Examples include the cherry vinegar fly and the marmorated stink bug.

If you choose the right variety, you won't be spoilt for pests

Resistance to certain pests is an important breeding goal for many plants. This topic of „resistance“ and examples of recommended varieties was the tenor of this presentation.

The guided tours in the afternoon complemented the theory. The tour in small groups was divided into the stations „Voles and traps“, „Use and promotion of beneficial insects“, „Monitoring measures in fruit growing“ and „Diagnosis of pathogens“. The drizzle did nothing to dampen the spirits during the guided tours. The thirst for knowledge of all participants could be felt until the end of the event and the extensive information on offer was fully utilised.
