For the control of various insect pests in asparagus, bananas, brassicas, cotton, forestry, ginger, wine grapevines, mushrooms, pasture, potatoes, sorghum sugarcane and swede as specified in the DIRECTIONS FOR USE Table.

DIRECTIONS FOR USE
Critical Comments: Dangerous to bees. Refer to PROTECTION OF LIVESTOCK.

ASPARAGUS
Pest: Garden weevil (Phlyctinus callosus)
State: WA, Vic only
Rate: 40 mL/100L applying 500L spray solution per hectare
WHP: 1 day (H)
Critical Comments: Day time spraying is effective but superior control may be achieved if spray is applied at night.
Repeat applications as required, depending on pest pressure. Controlling weevils in asparagus fern may reduce abundance the following season.
DO NOT apply more than 6 applications per season, up to 4 applications to spears and after harvest 2 applications.

BANANAS
Pest: Banana rust thrips (Chaetanaphothrips signipennis)
State: Qld, NSW, WA, NT only
Rate: 
Butt application
All planting configurations: 150 mL / 100 L water (0.75 mL/stool) Band application
All planting configurations: 40 mL/ 100 m2 treated area (See table under ‘General Instructions - Application’ for calculation of the treated area)
WHP: 1 day (H) 
Critical Comments: 
Timing
Application should ideally be made at least two months prior to bunch emergence to reduce early thrips pressure. Such an application could coincide with an application for banana weevil borer control (see label directions below).
Butt application
Apply in a coarse spray covering the stem to a height of 30 cm and the soil/trash in a 30 cm radius from the stem base. Apply a total volume of 500 mL solution per stool. Ensure thorough coverage of butt, suckers, trash and exposed soil.
Band application
Apply in a band along each row. The band width should be such that at least 30 cm of soil/trash is treated on both sides of the butt. Apply with a side delivery boom and offset nozzles directed to spray at least 30 cm of soil on either side of the butt and to a height of 30 cm up the stems. Repeat the application from the opposite side of the row. Half of the spray volume required to treat each row should be applied from each direction of spraying. For double row configurations, treat both rows with each pass, ensuring the ground area between
the two rows is also treated. Ensure thorough coverage of butt, suckers, trash and exposed soil. Apply in a minimum water volume of 13 L/100 m2 (trash removed) or 26 L/100 m2 (trash retained). See table under ‘General Instructions – Application’ for guidance.

Pest: Banana weevil borer (Cosmopolites sordidus)
State: Qld, NSW, WA, NT only
Rate: 
Butt application 
All planting configurations: 150 mL / 100 L water (0.75 mL/stool) Band application 
All planting configurations: 40 mL/ 100 m2 treated area (See table under ‘General Instructions - Application’ for calculation of the treated area) 
Critical Comments: 
Apply by butt application as described above for banana rust thrip.
Population assessment
Lay baits (cut billets of stem base) flat on soil beside stools and cover with leaf material.
Check baits after 3 days to assess pest activity. Monitoring should commence in September when pest activity increases and continue until April.
Application method
Applications should be made in Spring and/or Autumn when weevil numbers reach or exceed acceptable threshold levels. Remove any green trash from area to be treated.
Avoid application to trash which is less than 3 weeks old. This use is subject to an CropLife Resistance
Management Strategy. Refer to your BASF representative for details.

BRASSICAS
(head cabbage, cauliflower, broccoli, Brussels sprout, kohlrabi)
Pest: Diamondback moth (Plutella xylostella), cabbage white butterfly (Pieris rapae), cabbage cluster caterpillar (Crocidolomia pavonana)
State: All States
Rate: 250 mL/ ha
WHP: 7 days (H)
Critical Comments: DO NOT apply to flowering vegetation in which bees may be foraging or within 7 days prior to flowering. Refer to PROTECTION OF LIVESTOCK.
Diamondback moth can rapidly become resistant to insecticides. To preserve the effectiveness of REGENT 200SC, limit the number of applications to no more than 4 per year, preferably applied within an 8 week period. Use spray volume of between 400 and
1000 L/ha according to crop size. Use a nonionic wetting agent at the rate specified by the manufacturer for use in horticultural crops.
Ensure that the rate of wetting agent used results in efficient spray coverage of the leaf surface. This use is subject to an Avcare Resistance Management Strategy. Refer to your BASF representative for details.

COTTON
Pest: Apple dimpling bug, Cotton thrips (Thrips tabaci), Green mirid (Creontiades dilutus), Green vegetable bug (Nezara viridula)
State: Qld, NSW, WA only
Rate: 62.5 to 125 mL/ha
WHP: 4 weeks (H)
Critical Comments: Apply at the first sign of the pest. REGENT 200SC will take 3-4 days to reach full effectiveness.
Apply spray to achieve thorough coverage of foliage when pest first appears and repeat as required. Use the higher rate in situations
of high thrips pressure.
Use the higher rate under sustained
heavy green mirid pressure. Use higher rate in situations of high green vegetable bug pressure. The product is compatible with early season IPM with the lower rate having less impact on beneficials.

FORESTRY PLANTATIONS
including Eucalyptus, Pinus and Corymbia spp.
Pest: Australian plague locust (Chortoicetes terminifera), Spur-throated locust (Austracris guttulosa), Migratory locust (Locusta migratoria) Wingless grasshopper (Phaulacridium vittatum) Small plague grasshopper (Austroicetes cruciata)
State: All States
Rate: 6.25 mL to 12.5 mL/ha
WHP: -
Critical Comments: Apply in plantations situations up to a maximum of two years of age.
Apply diluted with water to a minimum of 20 L/ha by air or 50 L/ha by ground rig, directly onto locusts. Ensure thorough coverage of foliage. Residual control of these pests provided by Regent 200SC will vary with conditions.
Rainfall will significantly reduce residual control. Residual control will also be reduced when applied directly to bare earth.
Where inaccessibility prevents direct spraying of locusts apply as a barrier treatment (minimum 25 m wide) ahead of advancing hopper bands.
DO NOT retreat for 14 days following application. DO NOT apply Regent 200SC to wet foliage. Regent 200SC is rainfast after drying on foliage (1 hour). Respray only if rain falls before spray is dry on crop.
Mortality will increase to a maximum over a period of 3- 15 days after spraying. Speed of kill varies with locust species, temperature and age of adults. Fully mature, adult spur-throated locusts may show symptoms of debilitation 4-
48 hours after spraying but in cool weather may take up to 14 days to die. Feeding ceases
when debilitation symptoms appear. See also General Instructions.

GENERAL INSTRUCTIONS
INSECTICIDE RESISTANCE WARNING
GROUP 2B INSECTICIDE
For insecticide resistance management REGENT200SC is a Group 2B insecticide. Some naturally occurring insect biotypes resistant to REGENT 200SC and other Group 2B insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if REGENT 200SC or other Group 2B insecticides are used repeatedly. The effectiveness of REGENT 200SC on resistant individuals could be significantly reduced. Since the occurrence of resistant individuals is difficult to detect prior to use, BASF Australia Limited accepts no liability for any losses that may result from the failure of this product to control resistant insects. REGENT 200SC may be subject to specific resistance management strategies. For further information contact your local supplier, BASF representative or local agricultural department agronomist.

RESIDUES MANAGEMENT IN EXPORT PRODUCE
Crops
Growers should note that MRLs or import tolerances do not exist in all markets for produce treated with REGENT 200SC. If you are growing produce for export, please check with BASF Australia Limited for the latest information on MRLs and import tolerances BEFORE using REGENT 200SC.
Livestock
Livestock may be exposed to fipronil residues in the feed by grazing treated pasture and/or sorghum forage and fodder. Observance of the 14 day grazing withholding period permits compliance with Australian MRLs for fipronil in meat, offal and milk. To meet more stringent export residues requirements, Meat and Livestock Australia recommends Export Slaughter Intervals (ESIs) and Export Grazing Intervals (EGIs) for REGENT 200SC. When livestock grown for export are grazed on pasture and/or sorghum forage and fodder treated with REGENT 200SC the user must obtain details of the recommended export intervals from Meat and Livestock Australia and must follow those recommendations.

MIXING

Potatoes, Sweet Potatoes
Apply as a broadcast spray to the surface of the soil and incorporate to a depth of 15 cm prior to planting.
Swede and Turnip
Ensure thorough coverage of foliage.

AERIAL APPLICATION
Use spray techniques that minimise off-target spray drift. DO NOT use rotary atomisers. Use application volumes between 20 L and 50 L/ha. Achieve a droplet density of ~60 droplets/cm2 on a flat surface on the target. When spraying large droplets (>250 μm), increase the application volume to >40 L/ha to ensure sufficient droplets are produced. Aerial application is not recommended for brassica and potato crops.

PRECAUTIONS
Re-entry period
DO NOT allow entry into treated areas until spray has dried. When prior entry is necessary, wear cotton overalls buttoned to the neck and wrist (or equivalent clothing). Clothing must be laundered after each day’s use. Human flaggers, if used in aerial spraying operations, must be protected by enclosed cabs.
