Quality planting material is a basic requirement for the increase in productivity levels and one of the key indicators of quality is the health of nursery plants. Corynespora leaf fall disease (CLFD) affects all clones of rubber under nursery condition. In this investigation the most effective treatment to manage CLFD in nurseries was the introduction of overhead shading together with application of the fungicide mancozeb. The fungicide mixture (carbendazim + mancozeb) applied at 7-d intervals, and carbendazim sprayed at 2-week intervals together with shade showed equally good results. Carbendazim (0.5 g l–1) sprayed at 7- or 10-d intervals, the application of other fungicides, mancozeb, metalaxyl 8% + mancozeb 64%, captan and propineb, at 3 g l–1 at 7-d intervals was also effective. Though the systemic fungicide, carbendazim efficiently controlled the disease, tebuconazole and hexaconazole were found to be much less effective.

Screening von Fungizidwirkungen gegenüber der Corynespora-Blattfallkrankheit in Baumschulen


Qualitativ hochwertiges Pflanzenmaterial ist eine Grundvoraussetzung für Produktivitätssteigerungen und einer der Schlüsselindikatoren für ihre Qualität ist die Gesundheit von Baumschulpflanzen. Die Corynespora-Blattfallkrankheit (CLFD) befällt alle Klone von Gummibäumen in Baumschulen. Diese Untersuchung zeigt, dass die effizienteste Bekämpfungsmaßnahme der CLFD in Baumschulen in der Beschattung in Kombination mit einer Behandlung mit dem Fungizid Mancozeb besteht. Das wöchentlich applizierte Kombinationspräparat aus Carbendazim und Mancozeb sowie zweiwöchentlich ausgebrachtes Carbendazim in Kombination mit einer Beschattung waren ebenso wirksam. Carbendazim (0,5 g l–1), gespritzt in 7- oder 10-Tages-Intervallen sowie Mancozeb, Metalaxyl 8% + Mancozeb 64%, Captan oder Propineb, in einer Konzentration von 3 g l–1 wöchentlich appliziert, waren ebenfalls wirksam. Die Triazolfungizide Tebuconazol und Hexaconazol wirkten dagegen wesentlich schlechter.
