Boxwoods (Buxus spp.) are common woody ornamental hedging plants in Europe and North America, typically propagated by cuttings. In October 2011, shoot dieback and defoliation was observed on Buxus sempervirens ‘Suffruticosa’ (dwarf English boxwood) and ‘Green Balloon’ in outdoor, 10-cm pots at a wholesale nursery in Chilliwack, British Columbia. Circular leaf spots with black rings occurred on leaves and black, water-soaked, cankers girdled the stems and petioles. Leaf and stem samples were collected on November 21, 2011, and incubated for 48 h in a moist chamber at room temperature. In addition to Volutella buxi, a Cylindrocladium species producing conidia on white sporodochia was observed on host tissue under the microscope. Leaves with lesions were surface-sterilized in 10% bleach for 30 to 60 s, rinsed in sterile water, and lesions were cut out and plated on PDA and carnation leaf media. The species was identified as Cylindrocladium pseudonaviculatum Crous, J.Z. Groenew. & C.F. Hill 2002 by comparison of conidia and phialide morphology to published descriptions. Conidia were hyaline, one-septate, cylindrical with rounded ends and 38 to 76 μm (mean 51 μm) × 4 to 6 μm on carnation leaf media and 41 to 66 μm (mean 52 μm) × 4 to 6 μm on B. sempervirens ‘Suffruticosa’ leaves, comparable to the reported range of 40 to 75 × 4 to 6 μm (1,2,3,4). Conidia were produced in clusters on terminal, ellipsoid vesicles at the tips of penicillate conidiophores. Vesicles were 10.2 (7.6 to 12.8 μm) at the widest point, consistent with the 6 to 11 μm reported in (2,3) and tapered to a rounded point; stipe extensions were septate and measured an average of 130 μm (107 to 163 μm) in length to the tip of the vesicle, consistent with the 95 to 155 μm reported in (1), 89 to 170 μm reported in (2), and 95 to 165 μm in (3). Chlamydospores were not observed on host tissue but appeared in older PDA cultures as dark brown microsclerotia. DNA was extracted from single-spore colonies on PDA and the internal transcribed spacer (ITS) region of rDNA was amplified with primers ITS1 and ITS4. The ITS sequence (GenBank Accession No. KC291613) was 100% identical to C. buxicola strain CB-KR001 (HM749646.1) and Calonectria pseudonaviculata strain ATCC MYA-4891 (JX174050.1). In early December 2011, box blight was identified on container-grown B. sinica var. insularis × B. sempervirens ‘Green Velvet,’ ‘Green Gem’, and ‘Green Mountain’ and B. sempervirens L. (common or American boxwood). The pathogen was identified by microscopic examination at three wholesale nurseries in the eastern Fraser Valley and one landscape planting. The isolate has been deposited in the Canadian Collection of Fungal Cultures in Ottawa, Canada (DAOM 242242). References: (1) B. Henricot and A. Culham. Mycologia 94:980, 2002. (2) K. L.

Muriate Of Potash

Spraying romaine lettuce with either muriate or sulphate of potash eliminated leaf scorch (leaf breakdown) in six trials and significantly increased the yield of one. In one experiment radishes showed no foliage symptoms, but those sprayed with muriate of potash gave significantly higher yield. Leaf necrosis of Green Mountain potatoes was reduced markedly by potassium sprays in each of 4 years, while yields of U.S. No. 1 tubers were greatly increased in 3 years. Differences between muriate and sulphate of potash were not significant at the concentration used. Potassium sprays during the growing season may be profitable on crops grown in soils deficient in potassium.

At Home

From 2002 to 2011, coffee-machine manufacturer Keurig Incorporated had grown from a privately held company with just over $20 million in revenues and a plan to enter the single serve coffee arena for home consumers, to a wholly owned subsidiary of Green Mountain Coffee Roasters, Inc., a publicly traded company with net revenues of $1.36 billion and a market capitalization of between $8 and $9 billion. In 2003 Keurig had introduced its first At Home brewer. Now, approximately 25 percent of all coffee makers sold in the United States were Keurig-branded machines, and Keurig was recognized as among the leaders in the marketplace. The company had just concluded agreements with both Dunkin' Donuts and Starbucks that would make these retailers' coffee available for use with Keurig's specialized brewing system. The company faced far different challenges than when it was a small, unknown marketplace entrant. John Whoriskey, vice president and general manager of Keurig's At Home division, had to consider the impact that impending expiration of key technology patents and the perceived environmental impact of the K-Cup® portion packs would have on the company's growth. Whoriskey also wondered what Keurig's growth potential was, and how the new arrangements with Starbucks and Dunkin' Donuts could be leveraged to achieve it.
