What was it all about?

This Final Report concludes the third year of industry-supported field research undertaken to investigate the cause and control of an almond disorder currently confined to the northern Adelaide Plains (NAP). The Angle Vale Leaf Tatter and Defoliation disorder (LTD) has been the subject of investigations over four seasons. This project was a single-season extension of project AL05003c, approved for the purpose of repeating the field trials of 2006/07, a season in which LTD did not develop. Until season 2006/07 the LTD disorder had been widespread on the NAP and had resulted in economic losses over the previous four seasons.

This report includes information on the 2007/08 field trial established. It should be read in conjunction with the Final Report for project AL05006c, which includes field and laboratory research results from seasons 2004/05 - 2006/07.
