The most serious disease problem in fraser fir (Abies fraseri) Christmas tree production is phytophthora root rot (PRR). The efficacies of six fungicide treatments in preventing PRR incited by Phytophthora cactorum and P. drechsleri in 2-year-old fraser fir seedlings were evaluated in 2010 and 2011 in central Pennsylvania. The study examined five fungicide drench treatments [dimethomorph, foset...

Linepithema micans (Forel, 1908) (Hymenoptera: Formicidae) is the main ant species responsible for spreading ground pearl, Eurhizococcus brasiliensis (Wille, 1992) (Hemiptera: Margarodidae). The effect of different formulations hydramethylnon toxic baits (TB) was evaluated on control L. and E. brasiliensis. Four TB were in a greenhouse to micans. Based experiment results, small pellet formulati...

Background: Seaweed-derived extracts have gained popularity in agriculture as bioproducts with phytostimulatory effects on plant growth and development. Methods: This study assessed the effect of polysaccharide-enriched (PEEs) derived from six Moroccan seaweeds tomato growth, yield, fruit quality. PPEs were applied to plants soil drench a greenhouse experiment. Growth parameters including heigh...

We evaluated the branching response of established containerized perennials to spray or drench applications of Augeo (OHP, Inc.) applied during active growth as compared to Configure (Fine Americas, Inc.). Crops tested included Gaillardia ‘Gallo Yellow,’ Echinacea ‘Sombrero Hot Pink,’ and Phlox paniculata ‘Laura.’ Treatments were applied about 2 weeks after plugs were planted in 3.4-liter conta...

This presentation focuses primarily on recent developments in new technologies that have impacts on decay control. These technologies include 1-methylcyclopropene (1-MCP) and new preand postharvest fungicides. With the increasing use of 1-MCP in the apple industry, depending on varieties, many apples do not have to be drenched with diphenylamine (DPA) prior to storage. Because use of 1-MCP has ...

Wedetermined that spinosad interacts synergistically with the biocontrol agentMetarhizium anisopliae (Metch) Sorokin to increase the mortality of two wild-collected wireworm species, Agriotes lineatus(L.), andAgriotes obscurus(L.).BioassayswereperformedusingaM.anisopliae isolate originally acquired from a local wireworm cadaver.M. anisopliaewas applied as a soil drench at 3.3 10 and 10 conidia ...

A 12-year-old girl was referred to our department for evaluation of a 6-cm erythematous, brownish, indurated plaque that has been present on the sacral area since birth (Figure 1). The gluteal cleft was not deviated, and the lesion was not tender to palpation. The patient complained of profuse sweating that would drench her clothes. These symptoms were distressing and unrelated to emotional str...

High-density apple (Malus domestica) orchard management techniques and productivity were evaluated on an old orchard replant site in North Carolina. Trees were planted at 5 × 10 ft (1.5 × 3.0 m), giving a tree density of 871 trees/acre (2152 trees/ha). Well-branched ‘Smoothee Golden Delicious’ trees on ‘Mark’ rootstock were planted in 1990. Orchard-management factors which increased cumulative ...
