PLANT PROTECTION 1 – Pests, Diseases and Weeds FUNGICIDE ACTIVITY GROUPS Fungicides are classified by Croplife Australia into fungicide activity groups which assist in resistance management. The following tables are a summary guide only, and not a substitute for reading a currently registered label, the MSDS and obtaining up-to-date advice. They also provide an overall picture of the types of fungicides available for crop protection. Mark fungicides you use at work. Contact Croplife Australia for a full list of fungicides, updates of the classification and further information: www.croplifeaustralia.org.au Check Pubcris for current registration status: www.apvma.gov.au/ Infopest can be purchased www.dpi.qld.gov.au/ Table 58.
