APPLES
(Jonathon, Delicious)
Action: Advancement of maturity, improvement of red colour
State: Qld, NSW, Vic, SA, WA only
Rate (High volume): 28 to 52 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
(Tydeman’s Early)
Action: Advancement of maturity, improvement of red colour
State: Tas only
Rate (High volume): 20 mL/100 L water
WHP: 7 days
Critical comments: Ensure fruit has reached marketable size before treatment and keep trees under observation after spraying. Apply 2 to 3 weeks before normal harvest period and 7 to 14 days before desired harvest date. Ensure fruit is picked at the correct stage of maturity, as fruit not harvested will quickly become over-ripe. Note: For best results spray when temperatures are between 150 and 320C. Continuing low temperatures will advance maturity but may reduce colouration, so use lower rate. Use higher rate for quicker response. Add a “stop-drop” to prevent premature loosening of fruit. Thorough coverage is essential. Apply to fruit only for the fresh fruit market or short term storage.
(Gravenstein, Golden Delicious, Jonathan and Red Delicious)
Action: Thinning*
State: Vic, SA only
Rate (High volume): 12 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
Critical comments: Apply at full bloom OR up to 1 week following full bloom. A second thinning spray 10 to 14 days after the PROMOTE PLUS 900 spray may be necessary. On Gravenstein and Golden Delicious apply carbaryl or 5 to 7.5 ppm NAA (use higher rate for maximum thinning). On Jonathan and Red Delicious apply carbaryl or 4 ppm NAA.
(Golden Delicious, Stark Crimson and Legana)
Action: Thinning*
State: Tas only
Rate (High volume): 28 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
Critical comments: Apply at the balloon blossom stage using a high volume sprayer at 4000 L/ha. DO NOT apply if rain is imminent. DO NOT use in sequence or in mixtures with NAA. If maximum temperatures are below 130C after spraying, inadequate thinning may result, or if above 180C excessive thinning may result.
(Golden Delicious, Red Delicious, Jonathan, Granny Smith)
Action: Thinning*
State: WA only
Rate (High volume): 228 to 32 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
(Lady William)
Action: Thinning*
State: WA only
Rate (High volume): 36 to 52 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
Critical comments: Only use high concentration when heavy set expected.
*Note: For all thinning applications: The complex nature of fruit set and the possible variable action of chemical thinners due to weather conditions, make it difficult to give set recommendations and growers should consult their local agronomist.
(All Varieties)
Action: Aid complete removal of fruit from trees and encourage a biennial bearing habit (Excessive vegetative growth will be suppressed and the following bloom stimulated.)
State: NSW, SA, WA only
Rate (High volume): 52 to 108 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
Critical comments: Apply just prior to full bloom OR 5 to 6 weeks later during early morning or late afternoon when slow drying conditions occur. Ensure thorough coverage of foliage and flowers or fruit. Note: Under normal weather conditions use lower rate for Delicious and higher rate for Jonathans as they are difficult to de-fruit. Consult the local Department of Agriculture for specific recommendations on other varieties. Warm weather following treatment will improve results, but if temperatures below 180C prevail after spraying, fruit removal may be reduced, in the latter case use a higher dose rate. Fruit will loosen in 7 to 10 days and thinning should be complete within 2 to 3 weeks. Limbs can be lightly shaken to aid removal after this time.
Action: Retard vegetative growth and stimulate flowering of young apple trees in the following season.
State: NSW, SA, WA only
Rate (High volume): 52 to 108 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
Critical comments: Apply from full bloom to 6 weeks after full bloom.
Ensure thorough coverage. Trees should be large enough to support an increased crop of apples before being treated. Increase rate towards 108 mL/100 L to maximise thinning and stimulation of blooms during the following season. Note: Better results will be achieved if daminozide at 1000 ppm is added. DO NOT apply if harvesting fruit in same season as flowers or fruitlets will be partially or completely thinned.
BARLEY
Action: Anti-lodging
State: Qld, NSW, Vic, Tas, WA only
Rate (High volume): 268 or 400 mL/ha
(Barley varieties: Weeah, Malebo, Parwan only)
Action: Anti-lodging
State: SA only
Rate (High volume): 268 or 400 mL/ha
WHP: 1 day
Critical comments: Use the higher rate on tall, vigorous crops, on varieties susceptible to heavy lodging and on irrigated crops. Apply once only, between early to late boot stage, but before awns or spikes emerge. DO NOT apply to crops under moisture or disease stress or to crops that have already lodged. DO NOT apply if rain is expected within 4 hours or if temperature is less than 180C.
CHERRIES
(Ron’s Seedling, St. Margaret, Napoleon, Florence)
Action: Promote evenness of maturity; early colour development
State: NSW only: Young district
Rate (High volume): 16 mL/100 L water
State: Orange/Bathurst district
Rate (High volume): 32 mL/100 L water
WHP: 7 days
Critical comments: Treatment with PROMOTE PLUS 900: Apply when approximately 20% of the fruit show pink to red colour development, normally 7 to 10 days before harvest. Ensure thorough coverage of leaves and fruit.
Note: High temperature at spraying or following spraying may accelerate results.
DO NOT spray when mean daily temperatures exceed 320C. DO NOT spray when rain is expected within 24 hours OR when temperatures are low (170C or less) as this will delay or reduce the effect of PROMOTE PLUS 900. Fruit will mature 3 to 5 days earlier than normal and will be loosened to allow easier harvesting. A high proportion of fruit will readily separate from the stalk when harvested.
TABLE GRAPES
(Barlinka)
Action: To promote early uniform colouring
State: NSW, SA only
Rate (High volume): 12 to 16 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water

(Flame Seedless)
Action: To promote early uniform colouring
State: WA only
Rate (High volume): 20 to 32 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 14 days
Critical comments: Apply when 5 to 30% of the berries are coloured (2-4 weeks prior to expected harvest). Use the higher rate to maximise the colouring effects required. Ensure thorough coverage of bunches although the foliage need not be completely covered.
NOTE: PROMOTE PLUS 900 may slightly reduce firmness of grapes.
Do NOT use on grapes intended for long storage.
WINE GRAPES
(Semillon)
Action: Aids to mechanical harvesting
State: NSW only
Rate (High volume): 32 to 104 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
Critical comments: Apply 7 days before expected harvest. Thorough coverage of upper and lower leaf surfaces is essential. NOTE: Some leaf yellowing and leaf fall, which is not detrimental to vines, may occur. The concentration to use will depend on a number of factors such as seasonal conditions, crop size, weather conditions, before and after application, and trellis type. Therefore, before applying consult the local Department of Agriculture for specific recommendations.
MANDARINS
(Imperial)
Action: Thinning to increase fruit size, to reduce size of heavy crop and to even out the production cycle
State: Qld, NSW, SA, WA only
Rate (High volume): 28 to 32 mL/100 L water
State: Vic only
Rate (High volume): 20 to 28 mL/100 L water
ORANGES
(Navel)
Action: Thinning to increase fruit size, to reduce size of heavy crop and to even out the production cycle

State: Vic only
Rate (High volume): 32 to 36 mL/100 L water
WHP: Not required
Critical comments: Apply during the early stage of fruit development for thinning and correction of the habit of alternate heavy and light crops. Apply as foliar spray when fruitlets are about 10 to 15 mm in diameter and when natural fruit drop is occurring. This is usually in November in Qld, December in SA and intermediate in NSW, WA and Vic. Weather conditions influence the degree of thinning and care must be taken not to over-thin.
Note: Fruitlets should fall off 7 to 14 days after application. Aim to apply 13 to 15 L of spray per 4 to 5 m high tree. Use the higher rate when a very heavy crop is evident. DO NOT apply in cold weather (less than 180C) OR when rain is likely within 1 to 2 days of spraying. DO NOT add surfactants or wetting agents as leaf fall may be increased. See also General Instructions.
MACADAMIA NUTS
(Own Choice)
Action: Aid harvesting by promoting uniform nutfall
State: NSW, WA only
Rate (High volume): 132 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
(H2 Variety)
Action: Aid harvesting by promoting uniform nutfall
State: NSW, WA only
Rate (High volume): 44 to 84 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 7 days
Critical comments: Apply late March to early May when nuts are mature. Vary rate according to degree of loosening required. Note: Nuts will be stimulated to fall within 10 to 14 days after spraying. Mechanical shaking may be used 7 to 10 days after spraying. Ensure thorough coverage of foliage and nuts. Ensure tops and insides of trees are adequately sprayed.
A small quantity of older leaves will fall after treatment, but production will not be adversely affected. DO NOT use on Teddington variety.
PEACHES
Action: Advancement and concentration of maturity
State: Vic only: Goulburn Valley
Rate (High volume): 12 mL PLUS recommended rate of a suitable wetter (refer to Compatibility section) per 100 L water
WHP: 6 weeks
Critical comments: Apply once as foliar spray after commencement of the final fast growth stage. Timing depends on variety. Determine by measuring twice weekly, fruit circumference, of 20 tagged fruit/block. After rapid growth stage determined, wait 3 to 4 days for further confirmation, then spray. Thorough coverage is essential. Note: Instances have been recorded where this product, when applied in peaches at apparently the correct time, has resulted in premature fruit drop, fruit gumming and fruit splitting. See also General Instructions.
PINEAPPLES
Action: Fruit ripening
State: Qld, WA only
Rate:
General: -
Boom Sprayer: 1.36 L in 1000 L water/ha
WHP: 7 days
Critical comments: PROMOTE PLUS 900 for ripening should only be used on even crops successfully induced for flowering with PROMOTE PLUS 900. Do not use on fields intended for ratoon production.
Treatment should be made when the forced fruit are beginning to show the first colour break. An initial harvest amy be necessary to remove more advanced fruit before applying PROMOTE PLUS 900. The remaining treated fruit will be ready for harvest at least 7 days following the PROMOTE PLUS 900 ripening application.
NOTE: Do NOT use on fruit intended for the fresh fruit market. PROMOTE PLUS 900 for ripening is NOT SUITABLE FOR USE ON SUMMER PLANT CROPS because of scattered fruiting and high risk of forcing young suckers. Where natural fruiting has occurred prior to chemical induction, these natural fruit must be picked before PROMOTE PLUS 900 ripening. Treatment too early can result in a loss of yield and a reduction in fruit sugar levels.

GENERAL INSTRUCTIONS
IMPORTANT
Apples
– Advancement of fruit maturity and improvement of red colour:
- Ensure fruit has reached marketable size before treatment and keep trees under observation after spraying.
- Ensure fruit is picked at the correct stage of maturity, as fruit not harvested will quickly become over-ripe.
- Continuing low temperatures will advance maturity and colouration; continuing warm to high temperatures, both day and night, will advance maturity but may reduce colouration.
- Apply to fruit only for the fresh fruit market or short term storage.
Apples – Thinning:
The complex nature of fruit and the possible variable action of chemical thinners due to weather conditions, make it difficult to give set recommendations and growers should consult their local agronomist.
Apples – Fruit Removal:
- Apply to trees to remove unwanted fruit and encourage a biennial bearing habit. Excessive vegetative growth will be suppressed and bloom the following season stimulated.
- Weather conditions are very important – warm weather following treatment will improve results, but if temperatures below 180C prevail after spraying, fruit removal may be reduced. In the latter case, use the higher dose rate.
- Fruit will loosen in 7-10 days and thinning should be complete within 2-3 weeks. Limbs can be lightly shaken to aid removal after this time.
Barley:
Use only vigorously growing and potentially high yielding crops which are likely to lodge.
Imperial Mandarins and Valencia Oranges:
Apply during the early stage of fruit development for thinning and correction of the habit of alternate heavy and light crops. Weather conditions influence the degree of thinning and care must be taken not to over-thin.
EXCLUSION OF LIABILITY: As the degree of thinning may vary according to the conditions and over-thinning is possible, the decision to incur these risks is taken by the user, and the manufacturer and vendor exclude themselves from all conditions, representations, warranties, whether expressed or implied by statute or otherwise and accept no responsibility for any losses which follow from the use of the product on mandarins or oranges as far as this is legally possible under the Trade Practices Act or any State legislation.
Cotton:
A foliar spray with PROMOTE® PLUS 900 will accelerate opening of mature unopened bolls and enhance defoliation, which can result in earlier harvest and increased recoverable yield and quality. Some premature drop of small immature bolls may occur. Harvest at optimum boll opening and optimum defoliation. Too late harvest may reduce quality and lint.
APPLICATION – COTTON
Do not apply before sufficient mature unopened bolls have developed to produce the desired yield of cotton. Bolls are mature when the seed coat turns light brown, the embryo fills the seed cavity with an abundance of creamy colour and cotyledons are well defined.
TREATMENT SEQUENCE – COTTON
- Light canopy: Apply PROMOTE PLUS 900 then apply defoliant 4 to 7 days later.
- Moderate to heavy canopy: First apply a pre-conditioner, then apply PROMOTE PLUS 900 as soon as sufficient leaves have dropped to expose the large bolls, usually 4 to 10 days later.
APPLICATION METHOD – COTTON
Apply by placement technique under the following range of conditions to achieve a target droplet density of 60 droplets per square cm. Wind Direction: Cross Wind Wind speed range: 6-20 kph Air Temperature: Maximum 32°C Delta t: Maximum 10°C
Sugarcane:
PROMOTE PLUS 900 may be applied by air or ground spray equipment. Apply in 30 L water/ha by air, and 110-150 L water/ha by ground spray equipment. Apply during March-April on cane due for harvest no later than August. Consult your local Adama agent or BSES officer.
Tomatoes:
- Temperatures below 180C retard colour development and may extend the interval between treatment and harvest.
- Treatment may cause some yellowing of foliage or defoliation.
- Sun scald of exposed fruit may occur under high temperature conditions following treatment.
MIXING
Half fill the spray tank with water, add the required amount of product then the remainder of water and mix well. Do NOT use alkaline water.
