Ecology of Metarhizium anisopliae in soilless potting media and the rhizosphere: implications for pest management
Wholesale container-grown ornamentals are often maintained at the nursery for at least two growing seasons and are subject to infestation by black vine weevil (BVW), Otiorhynchus sulcatus F., for several months each year. Therefore, a potting media amendment aimed at controlling BVW needs to persist for an extended period of time. These studies were conducted to determine the persistence and ec...
متن کاملEfficacy Patterns of Biopesticides Used in Potting Media
Greenhouse nursery production represents a large and growing industry. In recent years there has been a shift both toward the use of soilless media and integrated pest management. Application of entomopathogens such as nematodes, fungi, and bacteria against soil-dwelling insect pests is a sustainable alternative to insecticide centered control programs. Soilless media (peat, coir, or bark-based...
متن کاملPersistence of Metarhizium anisopliae incorporated into soilless potting media for control of the black vine weevil, Otiorhynchus sulcatus in container-grown ornamentals.
The objective of this study was to determine the persistence of Metarhizium anisopliae (F52), measured as infectivity against black vine weevil larvae, in a soilless potting medium at six wholesale nursery locations across the Willamette Valley, Oregon. A granule formulation (0.30 and 0.60 kg/m(3)) was incorporated into media at planting and fungal persistence determined over two growing season...
متن کاملAnalysis of bacterial communities associated with potting media
BACKGROUND Potting media are commonly used by growers in different parts of the world for potted plants, raising seedlings and for improving soil characteristics. This study was conducted to characterize bacterial communities occurring in 13 commercial potting media products originating from seven countries. FINDINGS Bacteria were isolated using serial dilution. Identification to the species ...
متن کاملNative Plant Production in Potting Media Amended with Anaerobic Digested Cattle Biosolids
Anaerobically digested cattle biosolids are a by-product of cattle waste processing for pollution control and biogas production, yet this material has potential as an economical component of potting mixes used for sustainable nursery container production. As an animal waste, this material could have valuable fertilizer properties that could reduce the amount of supplemental fertilizer applied t...
