Stone fruit Aphids 150mL/100L 7 days Apply a maximum of two sprays per crop with a water minimum retreatment interval of 21 days between (proposed sprays. extension) Table 2 states as summarised below: Pome fruit and stone fruit are within the same related crop group of all tree & tropical fruit crops, risk assessment areas of OHS and environment indicate that extrapolation is possible to the crop group, and the risk assessment areas of residues, efficacy and crop safety indicate that extrapolation is not possible R OR C to the crop group. Crop Group Related Crop Risk Assessment areas Group Residues Efficacy Crop OHS Environment Safety Pome fruit All tree & tropical R C C fruit crops Stone fruit All tree & tropical R C C fruit crops In this example an applicant may lodge an application seeking extension to the whole crop group of stone fruit with a requirement to address residues, efficacy and crop safety in stone fruit. For the risk areas of OHS and environment a data and assessment waiver would apply. Such an application would be suitable under Item 14. Example 2 herbicide is currently registered in cereals for the control of capeweed. Extension is sought to the whole crop group oilseeds for the control of saffron thistle. – The proposed new use pattern in oilseeds will be no greater than that already approved in cereals (ie. rate, frequency and number of applications). The following table depicts the existing (cereals) and proposed registration (oilseeds). Crop Pest Rate Critical Use Comments Cereals Capeweed 750mL/ha Weeds should be young and actively growing and be up to 10cm in diameter (4-8 leaf). (existing registration) Oilseeds Saffron 750mL/ha Weeds should be young and actively growing and be up to thistle 10cm in diameter (4-8 leaf).
