Outline of presentation • Industry summaries • Proposed Controls • Biosecurity • ADIs • Conclusions • Note toxicology has not been a focus of the Hort/Arable review due to lack of time/resources

Summary of Industry Industries represented contribute over $2.7 billion to NZ economy and employ around 35,000 permanent and seasonal staff. Horticulture industry's goal to achieve industry value of $10 billion by 2020- The 10/2020 strategy. The Foundation for Arable Research 11 Product Groups affiliated to Horticulture New Zealand: – Avocado Industry Council – NZ Citrus Growers Inc – Persimmon Industry Council – Strawberry Growers NZ – Summerfruit NZ – Tamarillo Growers Assn – Onions NZ – Potatoes NZ – Process Vegetables NZ – Tomatoes NZ – Vegetables NZ

Arable Industry Mike Parker- Project Manager / Grower Foundation for Arable Research Sector statistics (2011) No. growers No. employees Land area (ha) Total value $(b) Crop Arable crops 4,000 5,750 262,300 1.1 incl. maize Critical use OPCs recommended for retention: • Chlorpyrifos, Oxamyl, Pirimicarb and Pirimiphos methyl - Agree Phase out Compound period (years) Comments Phorate 3 Agree – Assume diazinon retained Disagree - Critical for green vegetable bug Methamidophos 5 control Diazinon 10 Disagree - Critical for grass grub control

Arable Industry Diazinon and Methamidophos • Proposed time frames not sufficient to find alternatives – Grass grub = NZ pest, difficult to find controls – Green Vegetable Bug = probably requires new chemical group = more than 5 years • FAR working towards finding alternatives through a SFF grass grub research project to identify alternatives to diazinon (titled ‘ Managing the number one soil borne pest in cropping ’) • Request reassessment 2 years prior to phase out to ensure alternatives are available

Avocado Industry Dr Henry Pak- Technical Manager & John Cotterell, Grower Avocado Industry Council Ltd Sector statistics (2011) No. growers No. employees Land area (ha) Total value $(m) 1,600+ 1,062 4,247 82 Critical use OPCs recommended for retention: • Acephate, Carbaryl, Chlorpyrifos, Maldison and Pirimiphos methyl - Agree Phase out period Compound (years) Comments Pirimiphos Revised to long Agree - critical for control of methyl term retention leafroller, thrips and scale Disagree - Critical for scale, thrips Diazinon 10 and leaf roller control

Avocado Industry Diazinon • Do not support restriction to 2 applications per year - require 4 per year for thrips control • No alternatives available that meet market restrictions • Request reassessment 2 years prior to phase out to ensure alternatives are available Pirimiphos methyl • Revised recommendation appreciated – Acknowledges benefits – Agree with revised recommendation to retain outdoor use

Avocado Industry Thrips damage Leafroller damage

Citrus Industry Rick Curtis - Chairman New Zealand Citrus Growers Incorporated Sector statistics (2011) No. growers No. employees Land area (ha) Total value $(m) 421 1,521 (incl seasonal) 999 56.3 Critical use OPCs recommended for retention: • Acephate, Malathion/maldison, Pirimicarb and Diazinon – Agree • Acephate only option for control of Citrus Flower Moth • NZCGI appreciates EPA’s acknowledgement of benefits acephate provides to regional economy (Northland and Gisborne)

Strawberry Industry Peter McIntyre- Strawberry Growers New Zealand Sector statistics (2011) Land area No. growers No. employees (ha) Total value $(m) 110 7,380 (incl seasonal) 246 48 Critical use OPCs recommended for retention: • Chlorpyrifos and Methomyl and Pirimicarb – Agree Phase out period Compound (years) Comments Revised to long term Agree - critical for control of aphids Methomyl retention and other chewing insects Disagree - Critical control of beetle Diazinon 10 and caterpillar • Diazinon : Request reassessment 2 years prior to phase out to ensure alternatives are available • Methomyl: New information from DuPont - request EPA re examine REI & reduce to 24 hours

Strawberry Industry

Summerfruit Industry Dr Stephen Ogden- Market Access Manager Summerfruit New Zealand Sector statistics (2011) No. growers No. employees Land area (ha) Total value $(m) 258 5,500 (inc. packhouses) 1,830 68.5 Critical use OPCs recommended for retention: • Carbaryl, Chlorpyrifos and Pirimicarb- Agree • SNZ appreciates EPA’s acknowledgement of the benefits these compounds provide industry

Tamarillo Industry Robin Nitschke- Manager New Zealand Tamarillos Growers Assoc. Inc. Sector statistics (2011) No. growers No. employees Land area (ha) Total value $(m) 50 15 110 1.8 Phase out period Compound (years) Comments Methamidophos 5 Disagree - Critical for TPP control Diazinon 10 Disagree - Critical for TPP control • TPP has had an extreme impact on industry • Compounds essential for resistance management to control TPP • Recovery of industry relies on continued use until alternatives registered • Request reassessment 2 years prior to phase out to ensure alternatives are available • Off label use critical

Tamarillo Industry Liberibacter affected fruit (normal fruit on left) and leaves. Tree is still capable of setting fruit, but they are small, insipid and of no economic value. Tree will not return to normal growth patterns.

Process Vegetable Industry Dr Stuart Davis- Leaderbrand & PVNZ Process Vegetables NZ Sector statistics (2011) No. growers No. employees Land area (ha) Total value $(m) 680 268 (FTEs) 8,057 256.8 Key crops include*: • Beans • Peas • Field tomato • Sweet corn *processed potatoes and carrots covered in other sections

Process Vegetable Industry Critical use OPCs recommended for retention: • Chlorpyrifos, Oxamyl and Pirimicarb - Agree Phase out period Compound (years) Comments Phorate & terbufos 3 Agree – Assume diazinon retained Strongly disagree- Critical for nematode Fenamiphos 5 control in carrots Disagree - Critical for TPP, green vegetable bug, aphid, tomato fruit worm (= corn ear Methamidophos 5 worm) control Disagree - Critical for TPP and grass grub Diazinon 10 control

Process Vegetable Industry Benefits to sweet corn - Methamidophos for GVB control: Causes direct feeding damage • Has challenging physical and behavioural characteristics = hard to • control Research started in mid-1990s, ~ 20 years later still no alternatives • Benefits to beans /peas – Diazinon for grass grub control: • No alternatives Benefits to field tomato – Methamidophos & Diazinon for TPP control: • No alternatives, needed for resistance management Benefits to carrots – Fenamiphos for nematode control • Benefits of Fenamiphos for nematode control to carrots covered in Vegetables NZ section Request reassessment 2 years prior to phase out to ensure alternatives are available

Potato Industry Dr Stephen Ogden- Psyllid Coordinator Potatoes New Zealand Sector statistics (2011) No. growers No. employees Land area (ha) Total value $(m) 234+ ~2,500 11,717 560.3 Critical use OPCs recommended for retention: • Chlorpyrifos and Pirimicarb - Agree Phase out Compound period (years) Comments Strongly disagree- Critical for potato Fenamiphos 5 cyst nematode (PCN) control Disagree - Critical for Tomato Potato psyllid (TPP) and Potato Tuber moth Methamidophos 5 (PTM) control

Potato Industry Benefits of Methamidophos for TPP control: • Essential for control of TPP and zebra chip disease - affects both yield and quality of tubers • Used as part of a rotation in resistance management program • Effective due to systemic action when crops at full canopy • Since arrival of TPP (2006) large investment by PNZ. Total R&D expenditure ~$1.3m over last 2 years

Potato Industry Benefits of Methamidophos for PTM control: • Systemic action targets feeding insects - allows foliage to develop without being attacked by larvae – plant able to produce healthier larger tubers • Key component in resistance management of PTM • Request reassessment 2 years prior to phase out to ensure alternatives are available
