As a result of increasingly strict legislation on the use of pesticides, especially glyphosate, and pressure from society, alternative methods of weed control in permanent crops such as orchards and vineyards are gaining in importance. In a transnational cooperation, alternatives in weed management are therefore to be developed. In Bavaria, the project "Alternative weed management in fruit and wine growing with ecologically harmless substances and an alternative mulching method based on renewable raw materials - ABOW", submitted by the Technology and Promotion Centre in the Competence Centre for Renewable Resources (TFZ) Straubing together with the State Institute for Viticulture and Horticulture Veitshöchheim, was launched in January 2019. An Austrian project focusing on the development of an autonomous device and alternative substances in weed management was launched in summer 2019. In this project, the Institute of Plant Protection is investigating whether alternative natural substances and the sprayable mulch films developed in Bavaria have sufficient weed suppression.

In the years 2017 to 2019 an outbreak of the sugar beet weevil Bothynoderes punctiventris Germar (Coleoptera: Curculionidae) caused enormous damage to sugar beet crops in eastern Austria. The search for efficient pest control strategies raised question on the ecology of the sugar beet weevil that need to be researched under controlled conditions in the laboratory. Knowledge on the host plant selection behaviour of this pest is of particular importance for the development of novel control measures. To date the olfactory cues – or any other stimuli - used by the beetles to localize young sugar beet plants have not been investigated. The attractiveness of the odour bouquets of potential host plants other than the sugar beet to the weevil has not been researched either, and odour components present in the plant odours of secondary hosts have not been analysed, although olfactory attractive odour compounds could enhance the efficiency of the currently used attractant Grandlure III-V. Moreover, the potential of secondary host plants – crops, weeds or miscellaneous plants – to sustain the B. punctiventris population needs to be clarified. Finally, feeding deterrent plant extracts and minerals applied to young sugar beet plants may disrupt the host selection process of this pest. Research on the behaviour of the sugar beet weevil is a sine qua non for the development of future environmentally friendly and sustainable control strategies.

The project aims to detect the potential harmful organisms on garlic in the field and to assess their impact on Austrian garlic cultivation. Reliable laboratory detection procedures will be developed for the most important garlic pathogens. The development of soil and plant-derived diseases under changing climatic conditions will be analyzed across the entire production chain. Concepts for a reduction of infestation will be developed. Harvesting methods and harvest after-treatment as a possible cause of infection are analyzed. The project has the following objectives: 1) Biological data for the diagnosis and assessment of soil-borne fungi, focusing on Fusarium diseases. These data will provide the baseline or all further surveys, analyzes and recommendations. 2) Knowledge of the primary inoculum source for the further development of new garlic producing strategies: The focus is on two potential sources of inoculum for phytopathogenic fungi, in particular seedlings and soil contamination. 3) Knowledge of the potential sources of infection and contamination as well as disease-promoting operational measures, from cultivation to harvesting and storage. 4) Instructions for minimizing the occurrence of diseases. 5) Dissemination of knowledge 6) High-quality garlic from organic and integrated production for consumers.
