The industry’s official pest & disease guide was been facilitated by HIA Ltd (Horticulture Innovation Australia Limited) in partnership with the ABA. This Guide provides information on almond pests and diseases that can be managed and monitored by orchard managers.
The Australian almond industry has recently experienced both significant growth and challenges. New growers and investors, sizeable new plantings, the ongoing development of new production areas, and increasing compliance and regulatory pressures in the domestic and export markets, have resulted in great demand for production information and chemical use advice. This Guide has been prepared for the industry and should be viewed as a living document. It is accurate and up-to-date today but the rate of change in crop care technology (products, permits, registrations, chemistry, electronic support programs etc) is such that the Guide will require constant revision. Between reprints it will be the responsibility of growers to access and implement the latest information and recommendations. Useful sources of such information are included in the Guide.
This Guide includes technical information on the main almond pest and disease threats and products available for their control, it does not explicitly direct growers to specific crop protection products (or biological control organisms), application times or rates. Growers must make these choices in compliance with the product labels and when appropriate, export market requirements. Regional climates, varieties grown, disease pressure, pest populations, orchard history, previous product choices and tank mixes, resistance threats etc must be considered before designing and implementing your pest and disease control program. To finalise a program most growers will also look at the economics of the available product range.
The Guide provides information on almond pests and diseases that can be managed and monitored by orchard managers. The Guide does not include discussion of abiotic tree stresses (poor nutrition, soil problems, toxicities and deficiencies, irregular watering, water quality, heat, flooding, frost etc), but growers should recognise these factors may influence the onset or severity of the pests and diseases that are discussed. The Guide does not include information on viruses, viroids or phytoplasmas, or on disorders with unknown causes since the management of these is either undefined or is required before planting. Steps taken by growers before planting greatly influence the effectiveness of orchard management thereafter. Site selections, soil suitability, irrigation plans, choice of planting material, evaluation of planting material quality and health are critical steps in the establishment of good orchards.
