Evaluation of Visible-Near Infrared Reflectance Spectra of Avocado Leaves as a Non-destructive Sensing Tool for Detection of Laurel Wilt.

Laurel wilt, caused by the fungus Raffaelea lauricola, affects the growth, development, and productivity of avocado, Persea americana. This study evaluated the potential of visible-near infrared spectroscopy for non-destructive sensing of this disease. The symptoms of laurel wilt are visually similar to those caused by freeze damage (leaf necrosis).

Toward Fungicidal Management of Laurel Wilt of Avocado.

Laurel wilt threatens commercial and residential production of avocado (Persea americana) in Florida. Laurel wilt on redbay (P. borbonia) was controlled previously with macroinfusions (injections) of Alamo, an injectable formulation of propiconazole.

Scanning electron microscopy observations of the interaction between Trichoderma harzianum and perithecia of Gibberella zeae.

Chronological events associated with the interaction between a strain of Trichoderma harzianum, T472, with known biological control activity against perithecial production of G. zeae, were studied with scanning electron microscopy to investigate the mechanisms of control. Large clusters of perithecia consisting of 5-15 perithecia formed on the autoclaved, mulched wheat straw inoculated with G.

Parental distress around supplementing breastfed babies using nasogastric tubes on the post-natal ward: a theme from an ethnographic study.

There is abundant evidence of the benefits of breastfeeding. In the UK, supplementation in hospital has consistently been shown to be associated with shortened duration of breastfeeding. This paper reports on a subset of the data from an ethnographic study that explored the expectations, beliefs and experiences of mothers and health professionals concerning supplementation, using a variety of methods, of breastfed babies in an English maternity unit in 2002.

Breastfeeding Best Start study: training midwives in a 'hands off' positioning and attachment intervention.

The most common reasons cited by women for giving up breastfeeding early can be attributed to ineffective positioning and attachment and are therefore preventable. This study aimed to determine whether a 4-h training programme in 'hands off' positioning and attachment support increases midwives' knowledge and problem-solving skills. Using an unrelated comparison group and a pre- and post-intervention design, 108 midwives (experimental group) completed a 4-h standard breastfeeding training workshop focusing on effective positioning and attachment and the use of hands-off teaching methods.
