| Several products were tested for their efficacy in control of the apple seed moth (Grapholita lobarzewskii Ragonot). None of them had a good efficacy. With several treatments with Bacillus thuringiensis an efficacy about 50 % could be achieved. An early treatment before egg-laying seem to improve the results. Quassia extract (9 g Quassin/ha/m tree height) gave efficacy about 50-60 % even if treated only once. NeemAzal gave only moderate efficacy (about 40-50 %). Mating disruption method was effective if the populations were not too high when the treatements were started. With high populations there was no sufficient control in the first year of application. |

| Marssonina leaf blotch is a fungal disease of apple caused by the ascomycete Diplocarpon mali (anamorph: Marssonina coronaria). The pathogen origins from Asia where it accounts for crop losses of up to 100%. In Europe it was first detected in Italy in 2001 and is spreading since then in Switzerland and southern Germany (first reports in 2010), mainly in organic apple orchards and in orchards for cider production with a reduced fungicide regime. M. coronaria infects the leaves by using appressoria and shortly afterwards forms haustoria in the host cells. Blackish-violet spots appear on the upper leaf side, sometimes turning into star-like lesions. On the lesions acervuli are produced and eventually the leaves become chlorotic and fall off. First symptoms... |

| Die Toxizität eines Pflanzenschutzmittels (PSM)wird anhand von Untersuchungen der Herstellerfirmen ermittelt und beruht in der Regel auf der Wirkung eines einzelnen Wirkstoffes oder Produktes auf einen definierten Indikator-Organismus. In der landwirtschaftlichen Praxis werden die Wirkstoffe jedoch häufig in Kombination mit anderen Mitteln oder in rascher Abfolge ausgebracht. Zu den kumulativen Wirkungen von Pestiziden, wie sie in einer Kultur angewendet werden, gibt es bislang nur vereinzelte Untersuchungen (Bromilov et al. 1996; Moorman, 1989; Nicholson und Hirsch, 1998; Schuster und Schröder, 1990). In diesem Bericht werden die Ergebnisse aus einem Modellversuch über die kurz- und langfristigen Auswirkungen von PSM in der Kartoffelkultur auf die... |
