“…The experimental HPW system was based on the "standard" HPW system used in New Zealand for apples (also referred to as Honiball; Woolf et al 2015) with the modification of angled nozzles as described by O' Donoghue et al (2013) and Woolf et al (2014). Briefly, the system consists of eight rows of nozzles (ProMax® QuickJet® Spray Tips -QPTA-15-40: Spraying Systems, Auckland, New Zealand) over a rotating brush bed where fruit are treated for ca 15 s. The brush-bed is fixed, meaning that fruit-to-fruit contact moves fruit through the washer (Woolf et al 2014). The commercial HPW system was located on the packing line at Southern Paprika Ltd (SPL), Warkworth, New Zealand.…”

“…HPW is used commercially, as an industry standard, in New Zealand apple and avocado packhouses before fruit is sent for export (Woolf et al 2015) and is starting to be used commercially as a treatment for capsicums within a systems approach to control insects and disease. As defined in ISPM 14, a systems approach is the integration of different pest management measures, at least two of which act independently, and which cumulatively achieve the appropriate level of phytosanitary protection (IPPC 2014).…”

Pests on capsicum fruit can cause market access issues resulting in costly methyl bromide fumigation. High pressure washing (HPW) removes insects and other surface contaminants and has been commercialised for capsicums. This paper reports on performance of a commercial HPW system and compares it to an experimental HPW system that the commercial system was based on. The experimental high-pressure washing system operated at 75 or 100 psi (517 or 689 kPa, respectively) resulted in complete removal of aphids on capsicum fruit. The commercial washer at the same pressures removed 98.1-98.9% of aphids resulting in 85-95% clean fruit. HPW treatment increased incidence of soft rot and stem blackening with higher rot blackening at 100 psi. These results indicate the potential of HPW to be included as a mitigation measure in a systems approach to improve market access for capsicum. However, further optimisation in a commercial setting and evidence for efficacy against other pests of capsicum, such as tomato potato psyllid is required.

“…The Compac™ rotary apple washer utilises rapidly rotating nozzles to deliver water jets to apples rotating on conveyer roller cups ( Figure 1). The washer specifications were provided previously by Woolf et al (2015). For all washer trials reported here, the washer was operated with an elevator speed of 160 rods /min, a nozzle manifold pressure of 300 psi, fruit rotations set at 50 Hz with two rotors per lane.…”

“…The apple sector introduced "Honiball™" type washers (originally manufactured in New Zealand by Fruit Handling Systems Ltd (now Compac™), but copied by many manufacturers) into packhouses primarily to remove mealybugs in the late 1990s . This washer uses multiple overhead manifolds to spray water directly on to the fruit on a rotating brush bed at pressures between 80 and 120 psi for 10-20 seconds (Jamieson et al 2010;Woolf et al 2015).…”

Export markets require high-quality fruit, free from insects and mites of quarantine significance, and with minimal or no agrichemical residues. This presents a challenge for New Zealand's pipfruit sector when developing novel pest management systems to meet these market requirements. Brush-bed apple washers are an important component of a systems approach to remove insects and mites in packhouses before fruit are exported. A new apple washer using multi-nozzle rotors significantly reduced the incidence of insects and mites on apples. Weathered residues of kaolin and hydrated lime were similarly reduced by this apple washer. Assessment of fruit quality after apple washing and cool storage did not identify any commercially significant quality issues on the three apple cultivars examined. Apple washer design to optimise pest removal from all locations on the fruit is discussed.

“…Insects found on fruit destined for export pose a quarantine risk which can result in fruit being rejected at the border. A number of risk reduction treatments are available including cold treatment targeting scale insects (Jamieson et al 2009) and removal of mobile surface pests using brushing and/or high-pressure air or water (Woolf et al 2015(Woolf et al , 2017. Despite these alternatives, fumigation remains an important option for ensuring market access and methyl bromide has commonly been used as a fumigation option.…”

Mortality of kiwifruit pests (Coccoidea) exposed to ethyl formate delivered using either carbon dioxide or nitrogen carrier gases

Ethyl formate (EF) is used as a fumigant against insect pests on many commodities. Delivery of EF uses a carrier gas, usually carbon dioxide (CO 2 ), to reduce its flammability. However, CO 2 is expensive and can only be delivered relatively slowly. Nitrogen (N 2 ) has been proposed as an alternative. The efficacy of EF delivered using CO 2 or N 2 , was evaluated at 5 and 15°C, against two important postharvest pests of kiwifruit (greedy scale (Hemiberlesia rapax, Hemiptera: Diaspididae) and obscure mealybug (Pseudococcus viburni, Hemiptera: Pseudococcidae)). Mortalities of both insect species were higher in the presence of CO 2 than N 2 . There was a strong interaction with treatment temperature: N 2 at 5°C resulted in low mortality across both species. Greedy scale was more susceptible to EF than obscure mealybug across all treatments. Nitrogen as a carrier gas for EF substantially lowered the efficacy of EF as an insecticidal fumigant, relative to CO 2 . This is hypothesised to be caused by differing respiration rates across temperatures and CO 2 concentrations. Solutions for rapid CO 2 delivery should be explored over further trials with N 2 at low temperatures.
