Chocolate spot (CS) is one of the most destructive diseases affecting faba beans worldwide, leading to yield reductions of up to 90% in susceptible cultivars under conducive environmental conditions. Traditionally, the disease has been attributed to the fungal pathogens Botrytis fabae and Botrytis cinerea, however recent studies have identified three additional Botrytis species capable of causing the disease. Fungicide applications during flowering are commonly used to control the disease and limit damage to pod set, but this approach is not always effective. The reasons for this lack of control are not fully understood. To increase our understanding of the CS species complex in Norway, we used species-specific PCR to identify different Botrytis species in symptomatic leaves collected at various locations and years. Some Botrytis species are known to be high-risk pathogens for fungicide resistance development, but resistance in Norwegian Botrytis populations in faba bean have not previously been studied. Therefore, we obtained Botrytis isolates from diseased leaves and used a mycelial growth assay to assess their response to the active ingredients (boscalid and pyraclostrobin) in the fungicide commonly used for CS control in Norway. Resistance to both boscalid and pyraclostrobin was detected among B. cinerea isolates, while only resistance to boscalid was detected among B. fabae isolates. To elucidate resistance mechanisms, we analyzed target gene sequences for the presence of mutations known to confer resistance to the two active ingredients. Field experiments were conducted to test the efficacy of various spray timings and fungicides in early and late faba bean varieties. Additionally, we are developing a disease risk model for CS to better understand the conditions that lead to disease and to improve the timing of fungicide applications.

Over the past decades, significant efforts have been made to promote the cultivation of legumes. Cultivation of legumes, particularly grain legumes, can reduce the use of mineral nitrogen fertilizers, enhance biodiversity, reduce dependence on imported feed proteins, and improve soil biological properties and humus content. Despite these efforts, grain legumes are still not widely grown. One major obstacle to legume cultivation is "legume fatigue". Legume fatigue limits the expansion of legume cultivation in many European regions. The exact causes of legume fatigue are not fully understood, but soil-borne diseases interacting with abiotic factors are believed to play a key role. Recent findings suggest that the balance between pathogen load and soil suppressiveness is critical. Some farms and regions do not report legume fatigue as a problem, while others experience severe limitations in legume production. Identifying the causes of this variation is urgent and requires a collaborative effort that covers different environments and includes comprehensive assessments of both biotic and abiotic factors. In a recently launched project, LeFaSus, a network of farms and long-term experiments has been established to identify the primary factors contributing to legume fatigue. This network spans a transect from southern to northern Europe, including Italy, Germany, Luxembourg, and Norway. The project aims to deliver a reliable set of indicators for both legume fatigue and disease-suppressive soils, linking these indicators to the management practices that likely influenced them. The background and plans for the project will be presented.

Abstract
Sweet cherry fruit in Norway is sold to the domestic market for fresh consumption. Gradually the self-fertile and high yielding cultivar ‘Lapins’ has become dominant and in the 2024 season, cv. Lapins made up 60% of the total sweet cherry volume. The production of sweet cherry in Norway is located around three main packinghouses with minor to no differences in ripening time dependent on the weather conditions of the year. Situations with too much fruit on the market at the same time have been experienced, and fruit with a longer possible distribution time have been demanded from the packinghouses. In postharvest experiments, deliveries to the same packinghouse the same day exposed to exactly the same treatments were compared and differed in fungal decay from less than 5% to 60% after simulated shelf life. The dominating fungal decay was Mucor rot and grey mold. The risk of fungal decay pre- and postharvest on fruit grown in a humid climate (500 to 1700 mm annual precipitation) increases with high humidity under the plastic cover, with fruit-to-fruit contact in clusters, with incidence of non-developing or damaged fruit, and with minimal effect of the plant protection program. In order to improve the market situation in Norway, postharvest treatments alone are probably not enough. A holistic approach is needed through introduction of new cultivars with high yield potential that ripen over a longer period of time and are thoroughly tested in real scale experiments simulating distribution. A major challenge will be how to motivate growers to plant cultivars with potentially less income than possible with the self-fertile, high yielding cv. ‘Lapins’.
