1. John Gillett

2. Plant Regulator 480 or 720gms/L of Ethephon Releases Ethylene Ripening Senescence Nut drop Leaf drop

3. AMS has a permit from APVMA for ALL varieties ALL growing regions Label is WRONG Needs to be addressed

4. Standard spray equipment (air blaster) Poorly translocated in tree Good uniform coverage important Recommend use with a non ionic surfactant Spray to point of run off (inside and outside of tree)

5. Accelerates nut drop It does NOT initiate nut drop Nut drop MUST have started to drop nut before application Balance between In NSW April is suitable

6. Successful rate and application will cause Nut drop in 2-3 weeks after application Depending on variety between 60 90% nut drop

7. Reduced harvest costs Improvement kernel quality Opportunity to undertake other orchard operations Break pest/disease cycle Improved rat control Removes need for hand harvesting in young trees

8. Parasitic leaves aredropped Benefit to productive plant growth Leaf drop in tight varieites (A16 & Daddow) Increase light into canopy Improves spray penetration into canopy

9. Liaise with neighbours Very low toxicity Common courtesy Managing leaf fall No loss in yield in following season due to leaf fall Rate is different for each variety

10. Ethrel does not manage sticktights Sticktight is dead tissue Does not absorb ethylene Application needs to be prior to sticktights forming Trees under stress should NOT be sprayed with Ethrel Phytophthora, Canker, poor nutritionWet weather restrictingaccess for application

11. Logistics requires careful planning Application to blocks staged over several weeks Spray different areas at different times Harvester capacity Block 1 Block 2 Dehusking capcity SHED Block 3 Shed capacity Block 5 Block 4
