A Magnesium Oxide-based defluoridation technique using MgO-CaO-Calcium Chloride and pH adjustment by Sodium Bisulphate has been suitably modified for use with fluoride contaminated local groundwater having high alkalinity. Taking into consideration the high bicarbonate concentration in raw groundwater the proportion of the lime has been changed. It was found that sodium bisulphate was not suitable for pH adjustment due to the high concentration of sulphate in the pH adjusted water. Therefore dilute HCl was used instead. Six trials of the adapted defluoridation technique have been carried out in the laboratory successfully at a 50-litre scale.

Control Activity

Ten compounds were evaluated for their effects on the efficacy of the bacterial biological control agent (BCA) HR42 against the avocado postharvest rot fungus Colletotrichum acutatum The effects of the 10 compounds (chitin Dglucose glycol chitosan Lserine Laspartic acid calcium chloride calcium carbonate potassium chloride ammonium molybdate and sodium carbonate) at four different concentrations (1 10 100 and 1000 mM) were tested separately on bacterial and fungal growth Lserine Laspartic acid and calcium chloride all stimulated growth of HR42 and suppressed mycelial growth of C acutatum The BCA and these compounds were then tested in combination on detached avocado fruit for their ability to inhibit lesion development following woundinoculation A high concentration of HR42 (107 cfu/ml) significantly inhibited the development of lesions caused by 105 and 107 conidia/ml of C acutatum There was no improvement of control by the addition of any of the three compounds These results show that HR42 has biocontrol activity against C acutatum in a detached fruit test but there was no enhancement of control by the addition of supplements
