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 and WARNINGS
Avoid spray drift onto neighbouring crops.
Do not apply TROY 480 to any crop that may have been subjected to stress conditions, such as herbicide or disease injury, excessive acidity/alkalinity, trace element deficiency, drought, waterlogging, widely fluctuating temperatures, or physical damage to the foliage as caused by abnormal wind, rain, hail or frost
A satisfactory leaf wax test using crystal violet marker dye, must be carried out before applying TROY 480 to peas. All the factors above can result in a reduction in the leaf wax protection
Do not spray under HOT SUNNY CONDITIONS when temperatures are at or above 21°C, particularly during the mid-day period.When these conditions occur, spraying should be delayed until the evening. This is particularly important when there has been a change to hot sunny weather following a cool cloudy period.
Do not spray under HOT SUNNY CONDITIONS when temperatures are at or above 21°C, particularly during the mid-day period.When these conditions occur, spraying should be delayed until the evening. This is particularly important when there has been a change to hot sunny weather following a cool cloudy period.
Do not spray if rain or frost is expected, nor if the foliage is wet. A minimum period of 6 hours free from all rain is required after application. 
Do not apply TROY 480 during periods of drought or unseasonably cold weather as unsatisfactory weed control may result. 
Do not overlap spray swaths. 
Crops must be treated at correct stage of growth to avoid danger of scorch. Apply to broad beans from 3 to 4 leaf pairs only. 
Consult processor before using on crops for processing.

Not all varieties are fully tolerant. Refer to the varietal tolerance lists for each crop. The following varieties have successfully been tested: 
Potatoes King Edward, Maris Piper 
Linseed Antares 
Early fodder peas Baccara, Solara, Madria

A number of varietal screens have taken place, contact your local distributor for more information. 
Do not apply insecticides within 7 days of treatment with Troy 480. 
TROY 480 BEFORE a post-emergence grass herbicide – Leave an interval of at least 7 days between treatments. 
TROY 480 AFTER a post-emergence grass herbicide – Leave an interval of 14 days and carry out a leaf wax test where relevant. 
TROY 480 must not be used on plants which are destined for seed production or for propagation.

WEED CONTROL
TROY 480 is a post-emergence contact herbicide for the control of broadleaved weeds. It is absorbed mainly by the foliage, with very little translocation. It is also absorbed by the root with translocation in the xylem providing control of broadleaved weeds in crop and horticultural situations. TROY 480 controls a great number of weeds, as shown in the table below.
The best weed control is achieved if crops are sprayed when weeds are small and actively growing, provided the crop is within the correct growth stages.
The split dose programme will only provide control up to the 2 leaf stage for S weeds and up to the cotyledon stage for MS weeds.

CROP SPECIFIC INFORMATION
Apply TROY 480 as a single dose in all recommended crops or as a split dose in dwarf French, runner, navy, winter field, spring field and broad beans, linseed, potatoes and ornamentals (narcissi).
It is recommended to apply the split dose when the weeds are small (maximum 2-leaf stage). If necessary a second application can be made to small, newly emerging weeds. A maximum of two applications can be made.
Where weeds classed as moderately susceptible constitute an important part of the weed population and have true leaves the single dose is necessary. The split dose will only give acceptable control if the weeds are at cotyledon only.
The split dose will only give acceptable control if the weeds are at cotyledon only. 
The split dose has generally given better weed control and enhanced crop safety over the single dose.

Dwarf French and Runner Beans
Apply TROY 480 to runner beans when the crop has between one and two trifoliate leaves and in dwarf French beans as soon as the crop has two foliate leaves.
Crop selectivity is partly dependent on adequate leaf wax formation. When conditions which reduce leaf wax occur the application should be delayed by at least 5-7 days to await recovery.
Apply either as a single dose, or preferably, as a split dose.
TROY 480 may cause transient scorch, which can be prolonged with applications later than the three trifoliate leaf stage.
The following varieties of Dwarf French Beans can be safely treated: Adora, Amira, Anne, Arena, Aurora, Bef, Bertires, Bilbao, Bliss (Blulect), Boreal, Brelan, Brio, Burly, Bush Blue Lake 274, Cantare, Cape, Caravelle, Carnato, Cascade, Cavalier, Celero, Checkmate, Cimbola, Corumba, Diane, Faria, Flevoro, Flo, Forum, Fran, Frigor, Gitana, Greenpak, Gresham, Groffy, Highway, Holt, Ingo, Iprin, Kent, Kingreen, Labrador, Laguna, Lake Shasta, Lancer, Lasso, Lit, Lochness, Maestro, Maradonna, Masai, Matador, Mikado, Milagro, Mirel, Modus, Mondeo, Montano, Musketeer, Mutin, Narbonne, Nassau, Nerina, Newton, Niagara, Nickel, Nomad, Odessa, Optimus, Ovation, Paulista, Prevato, Provider (Dark seeded), Rise (Peak), Rodolfo, Roma II, Romil, Rondina, Safari, Sapporo, Slenderette, Solido, Stip, Tendercrop (White seeded), Tilla, Utopia, Vaillant, Valja, Varlon, Verto, Viking, Vona and Xera.
The following varieties of Dwarf French Beans are recommended on the basis of limited (2 years) data: Atlanta, Carlo, Fiesta, Florence, Kylian, Laureat, Magnum, Marcio, Pix, Primera, Rasada, RS 1384, Scylla, Sentry, Sigma, Tasman, Ursus and Yukon.
The following varieties of Dwarf French Beans are slightly sensitive and may exhibit more leaf scorch than other varieties but this is outgrown: Acapulco, Amity, Arcadia*, Clyde, Delfina*, Label, Larissa, Maxima, Niki, Novores, Orca, Palermo, Piccolo, Rovita*, Salerna, Simpson, Swing, Taverna and Ventura. 
*: 2 years data only
The following varieties of Runner Beans can be safely treated: 
Achievement, Emergo, Enorma, Kelvedon Wonder, Kelvedon marvel, Prizewinner and Streamline.

Spring and Winter Field and Broad Beans
Apply TROY 480 as a single dose preferably for treatment of winter field bean crop, due to overwintered weeds being more advanced. Due to the sensitivity of broad beans and spring field beans, apply TROY 480 as a split dose provided that the weed and crop stage are suitable. The split dose should be applied between 2 leaf pairs and 6 leaf pairs (max height 15 cm). The single dose should be applied up to 3 to 4 leaf pairs. The optimum crop stage for both applications is 5 to 10 cm. If conditions are conducive to increased herbicide activity and crop scorch e.g. warm sunny conditions, tender foliage or a more sensitive variety, then the 1.5/1.5 litres/hectare split should be used.
Crop selectivity is partly dependent on adequate leaf wax formation. Frost, wet conditions, physical damage, disease or previous sprays can all reduce leaf wax and when this occurs applications should be delayed by at least 5-7 days to await recovery.
The following varieties of Broad Beans can be treated: Beryl, Bistro, Brandy, Brunette, Danko, Diamant, Felissa, Foxton, Gold, Greeny, Jade, Listra, Metissa, Statissa, Stereo, Threefold White, Turbula and Verdy.
The following variety of Broad Beans is recommended on the basis of limited (2 years) data: Bailey.
The following varieties of Broad Beans have shown more sensitivity: Albinette, Bianca, HS 500, Medes, Minica, Optica, Rowena, Scorpio* and Talia. 
*: 2 years data
Use only the split dose treatment on these varieties.
In Broad Beans slight crop scorch can occur after spraying. This is seen as a blackening of leaf margins, especially on older leaves – all subsequent new leaves being unaffected. A temporary vigour check may also occur under some conditions. These effects generally have no influence on yield. They can, however, be more pronounced when applications are made beyond the optimum growth stage, particularly when the single dose is used and/or adverse weather conditions prevail.

Peas (picking peas, vining peas and combining peas)
Apply TROY 480 when the peas have three nodes (3 fully expanded leaves) until before the flower buds can be found enclosed in the terminal shoot. The optimum timing is when the majority of weeds have germinated, but are still at the seedling stage.
Only single dose applications are suitable for peas.
Avoid application to crops which are under stress from physical damage or disease, or other factors.
A satisfactory leaf wax test using crystal violet marker dye must be performed before applying TROY 480, particularly with early drillings which tend to have less leaf wax.
Slight scorch of the leaf margins and/or hormonal twisting may occur shortly after spraying but the crop will soon recover; yield and maturity will not be adversely affected.
Do not treat forage peas varieties, or mange-tout.
The following varieties of Vining Peas can be safely treated: Bikini, Dark Skinned Perfection, Fulmar, Gannet, Harrier, Hurst Greenshaft, Jade#, Jof, Johnsons Freezer, Legend, Markado, Markana, Polo, Progress No 6, Puget, Scout, Small Sieve Perfection, Small Sieve Freezer, Stampede, Trio, Tristar and Waverking.
The following varieties of Vining Peas are recommended on the basis of limited (2 years) data: Barle and Sancho.

The following varieties of Vining Peas are slightly sensitive: Ambassador, Ayola# (Spring), Banff#, Bastion, Coral, Daybreak*, Dew, Early Onward#, Feltham First#, Misty, Multistar, Onward, Pennine*, Progres No 9#, Skinado, Holiday, Hunter, Hurst Beagle#, Kelvedon Wonder#, Lynx, Span# Sparkle#, Sprite#, Waverex, Wavertop and Winner*.
*: 2 years data
Particular care should be taken to ensure that early maturing varieties marked with # are treated at the correct growth stage, because they flower at an earlier node than later-maturing varieties. They should not be treated after the fifth expanded leaf stage.
Do not treat the varieties Carouby de Mausanne, Conquest, Danielle, Dinos, Filby, Fonado, Printana, Turon, Santa, Sherbourne or Vedette.

Linseed
Apply TROY 480 when the crop is between 2½-30 cm tall, but before flower buds are visible. The optimum timing is when the majority of weeds have germinated and are still in the seedling stage.
Apply either as a single dose, or as a split dose.
TROY 480 may be used alone or following pre-emergence herbicides, provided that the crop is showing no adverse symptoms.

Potatoes
TROY 480 may be applied following a pre-emergence herbicide provided the crop is undamaged and showing no adverse symptoms of herbicide application.
Apply TROY 480 when the majority of the weeds have emerged and are at the cotyledon to seedling stage, but before most of the crop has reached a height of 15 cm. Application when the crop is taller than 15 cm may cause foliage scorching leading to a possible check in crop vigour and yields. Weeds can also be shielded from the spray by crop foliage with later applications.
Apply either as a single dose or as a split dose.
May be used on selected varieties of maincrop and second early potatoes, not on seed crops or first earlies.
Do not apply following a post emergence application of metribuzin.
Some leaf yellowing or slight scorch may occur under certain conditions. These effects are transient; only being present on leaves exposed to the spray. All subsequent growth is unaffected and yields are not adversely affected provided that applications are within the following guidelines.
Do not irrigate for at least 24 hours following application. In dry conditions irrigation prior to TROY 480 application can be beneficial to ensure that weeds are actively growing. Foliage must be dry before application.
Do not spray under HOT SUNNY CONDITIONS when temperatures are at or above 21°C, particularly during the mid-day period.When these conditions occur, spraying should be delayed until the evening. In general, crop foliage is more sensitive when there is a sudden change to hot sunny weather following a cool cloudy period. This sensitivity diminishes after approximately three days.

The following maincrop and second early varieties can be safely treated: Ambo,Ausonia, Brodick*, Cara, Costello, Cultra, Erntestolz*, Marfona, Maris Piper, Maris Peer, Nadina, Navan* Obelix*. Pentland Crown, Pentland Dell, Pentland Squire, Record, Romano, Saturna*, Saxon*, Shula*, Wilja, Vekaro and Vanessa. 
*: 2 years data

The following varieties have shown more foliage scorch than others: Ailsa*, Picasso*, Premiere*, Balmoral*, Desiree, Estima, Hermes* and King Edward.
*: 2 years data

Particular attention should be paid to the crop growth stage and factors affecting crop tolerance.
Do not treat the following varieties: Bintje, Fianna, Lady Rosetta, Morag, Morene, Rode Pipo, Russett Burbank, Sante, Shepody, Stemste and Stroma.

Application Timing 
Timing for Single Dose
TROY 480 should be sprayed when weeds are small and actively growing, provided the crop is within the correct growth stages. See individual crop growth stage limitations.

Timing for Split Dose
The optimum timing for TROY 480 for the first application is when the weeds are at the cotyledon stage. The second dose should be applied within 7-10 days of the first dose, depending on the control achieved by the initial dose or the appearance of the second weed flush.

Volume
Apply TROY 480 in 220-450 litres/hectare of water for the single dose. The lowest volume should only be used when weeds are at the cotyledon - 2 leaf stage, weed density is low to moderate and crop shielding is negligible. For other situations 330-450 litres/hectare of water is recommended. For the split dose 100-220 litres/hectare water is recommended. The lowest volume can only be used when weeds are no larger than cotyledon stage, weed density is low to moderate and crop shielding is negligible. TROY 480 should be applied as a FINE spray (as defined by BCPC). At higher volumes, FINE or MEDIUM sprays are permissible. Adjust spray volumes and pressures according to the size and density of the weed populations and crop cover.

MIXING AND SPRAYING 
Fill the tank or container with half required volume of water and add the correct amount of the product. Add the remainder of the water and continue agitation until spraying is completed.
