Solutions of sodium o-phenylphenate control green mould wastage sue to (Penicillium digitatum) but can cause rind injury in oranges. Data are given on the effects of varying concentrations and pH levels of sodium o-phenylphenate solutions, duration of dip, rinsing, and the addition of hexamine. The occurence of rind injury is due to the absorption of o-phenylphenate and the effectiveness of waste control depends on the levels of both sodium o-phenylphenate and o-phenylphenate. The degree of rind injury depends primarily upon the concentration of o-phenylphenate in the solution, which can be controlled by pH adjustment. Accordingly, an explanation of the role of hexamine is given. Sodium o-phenylphenate control of mould wastage is superior to control by borax-boric acid.

The adsorption of B, in the form of boric acid, was studied on three precipitated humic acids (HA), representing three distinct soil types. B adsorption by HA was strongly pH-dependent, being low and relatively constant in the pH range 3.0–6.5, increasing markedly up to a peak at near pH 9.5, and then decreasing at still higher pH values. Adsorption isotherms for pH values near 6.7 and 8.8 conformed well to the Langmuir equation. The adsorption maxima (b values), as calculated with the Langmuir equation, ranged from 73 to 207 mmol kg−1 HA at a pH near 8.8, and from 10 to 42 mmol kg−1 at a pH near 6.7. The considerable variation in B adsorption by these HA samples was attributed to "Fe + Al" contents present as contaminants in the HA. The role of HA in B adsorption is expected to be minor in most acid and near neutral soils, but may be of greater significance in soils of high pH and above average organic matter content. Key words: Boron adsorption, boric acid, humic acid, Langmuir adsorption isotherm.

Thiabendazole and benomyl were compared for their effectiveness in controlling major postharvest diseases of lemons, caused by green mould (Penicillium digitatum Sacc.) and stem-end rot (Diaporthe citri (Faw.) Wolf). The lemons were stored at ambient temperatures and at 12�C and examined over a period of 26 weeks. Results showed benomyl gave excellent and better control of the diseases than TBZ. Although benomyl treated fruit was sound, skin colour was deep yellow and unattractive indicating the need for further research into methods of improving fruit appearance during long periods of storage.

AbstractBoric acid, H3BO3, is a weak acid and at physiological pH is in the form of an uncharged small molecule. Behaving as a Lewis acid, it forms complexes with amino- and hydroxy acids, carbohydrates, nucleotides and vitamins through electron donor-acceptor interactions. These interactions are believed to be beneficial for human health. Synthetic bis-chelate complexes of boric acid with organic biomolecules are therefore considered for nutritional and/or pharmaceutical applications. The use of boric acid for BNCT has gained attention due to the short biological half-life, solubility, plasma circulation and the non-selective soft tissue accumulation properties of this simple molecule. Complexation of boric acid with sugars is of particular importance in understanding the role of boron as a carrier for nucleotides and carbohydrates. A potential and catalytic role of boric acid in peptide and nucleic acid synthesis and in the stabilization of sugar molecules by acting as a complexing agent have been demonstrated. Its possible role as a phosphorylation chaperone in a prebiotic world has been recently suggested. This contribution reviews the highlights in the physiologic, therapeutic and prebiotic significance of boric acid in the last decade.
