DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

RESTRICTIONS OR WARNINGS
DO NOT USE on seed potatoes.
DO NOT fog potatoes with a high level of skin spot.
DO NOT use NeoStop 500 HN on potatoes stored in Graves, 'Dickie Pie' or modified 'Dickie Pie' type stores. When treating potatoes in bulk stores by this method, sprout control may be poor in the top 30 cm of the store.
It is VERY IMPORTANT to ensure that the air circulates gently (no more than a flickering match above the uppermost layers), freely (no clods or debris amongst the potatoes) and uniformly through the stacks or boxes. Blockage of air spaces between the tubers prevents adequate circulation of vapour with consequent loss of treatment efficacy.
Strictly, do not apply NeoStop L500 HN to potatoes immediately after harvest as sprout inhibitors based on chlorpropham (CIPC) may cause skin damage to potatoes which are sensitive and/or insufficiently cured. In addition, slower wound healing will increase the risk of infection with storage diseases. Under climatic conditions favourable to these diseases, this can result in an increase in damage during storage and loss of quality. Do not treat ANY potatoes until after the curing period, particularly potatoes which are sensitive to skin damage (e.g. ‘thin-skinned varieties’). Seed crops of any type must not be stored in buildings in which potatoes are being treated. There is also a risk of damage to propagating material (seeds, tubers, runners, etc.) which are handled or stored in buildings or boxes previously treated. This applies to seed potatoes, malting barley, seed grains, grass seed, ALL other seed crops and plant material for propagation such as raspberry canes.

Any commodity handled or stored in previously treated boxes or stores may also become contaminated leading to an exceedance of the maximum residue level (MRL).

Do not sell treated potatoes for consumption or processing for at least 2 days after the final application.

Crop
To be used only on potatoes intended for direct consumption. Consult processors before using on potatoes destined for processing.
Do not treat potatoes until after the curing period. Thin skinned varieties and those with storage diseases are particularly sensitive to premature treatment.
Potatoes should be clean, dry and free from signs of disease. Ensure skin is sufficiently cured before treatment. Daily crop inspection is essential to check curing and onset of sprouting.
For best results, treat before the eyes have opened.
Use only in stores with forced air/ducted ventilation to ensure uniform air flow and to avoid blockage of air spaces between the tubers which can impede efficacy of the product and lead to a build up of condensation.

Application Method
NEOSTOP L500 is a ready to use product to be applied using suitable thermal fogging equipment. Follow the manufacturer’s instructions when using this type of machine.
Fogging should ideally be carried out with the fogging machine outside the warehouse with the fog being fed into the store through a treatment port or other secure means. Only stores dedicated for potato storage should be treated.
A forced air ventilation system should be in place to allow distribution of the fog through the potatoes and to avoid the build up of condensation. All other external vents and doors should be closed during treatment to ensure the store is airtight. It is very important to maintain a gentle flow of air during treatment.
Do not leave the fogger unattended during application.
The engine of fogging generators produces considerable heat during operation. Care should therefore be taken to avoid contact with flammable/combustible materials (e.g. straw, plastics, paper or wood).
The fog generator should have a mechanism which ensures that delivery of the product will cease if for any reason the motor stops (e.g. due to lack of fuel). Otherwise the lack of air flow could cause the product to burn on contact with hot surfaces.
The fog generated should not be directed directly into an air duct in order to avoid loss of the product onto the walls and fans. Instead it should be directed into an open area where it can be circulated before being drawn up by the ventilators. During application switch off lighting or any other electrical apparatus in the store (except the ventilators themselves) until the fog has settled.
Ventilate the treated store thoroughly with fresh outside air once the fog has cleared and the product has settled, usually 6-8 hours after application.
Best results are achieved at a temperature range of 5-10°C
Do not enter treated areas for at least 12 hours after treatment.
Inspect the stored crop at regular intervals to assess the need for re-treatment or the need to remove the potatoes from store. These inspections are necessary when potatoes are stored in boxes, where persistence may be reduced due to absorption of the hot fog by the wood.

Rate of Application
Potatoes for processing: Apply 24 ml NEOSTOP L500/tonne of potatoes 3-4 weeks after harvest (once curing is complete), then 16 ml/tonne every 2-3 months with a maximum of 72 ml/tonne, per season. This should be sufficient to control sprouting for up to 12 months.
Potatoes for the fresh market: Apply 16 ml NEOSTOP L500/tonne of potatoes 3-4 weeks after harvest (once curing is complete) and one further application of 14 ml/tonne 2-3 months after. This should control the sprouting for 6-7 months.
There must be a minimum of 28 days between applications.

Potatoes for processing
Darker fry colour has been linked to increased frequency of hot fog application. Stored crops destined for crisp or chip manufacture should be treated with the minimum number of applications, where a light fry colour is desired.
