General Instructions


FMC Repay PGR is a systemic growth regulator that reduces internode lengths of new shoots and causes earlier formation of terminal buds. Use of FMC Repay should begin only when trees are nearing their optimum size. It is most suited to intensively managed orchards where trees are near to filling their allocated space and growth control is a prime requirement. It is not suitable for old or unhealthy trees. If a tree is under stress FMC Repay should NOT be used.


Stress can be caused by:

  • moisture shortage due to lack of rain, or inadequate irrigation

  • high temperature

  • salinity

  • moisture excess due to water table, flooding or inappropriate irrigation

  • severe or successive frosts; poor fertility caused by imbalance of major or minor nutrients, diseases, insects, inappropriate herbicide use, mechanical damage.

Tree Management

Treated trees may produce heavier crops and require a higher level of fertilizer application. Ensure that treated trees are not over-watered or subjected to drought stress. In some instances, treated trees may set excess fruit and careful attention should be given to thinning operations. When replanting a treated orchard, at least 3 years should elapse since the last application for FMC Repay. In orchards, which have been treated with collar drenches of FMC Repay, fresh soil should be provided to allow tree establishment and growth. Remove treated soil. An alternative is to avoid original tree-holes, and place young trees as far as practicable from the treated soil (minimum 1.5m). Where young trees are required to be planted in an established orchard which has been treated with collar drenches of FMC Repay remove treated soil and replace with fresh soil.




DO NOT use on trees of low vigour or under stress (see General Instructions).

DO NOT use in orchards under-planted with any other crops.

DO NOT apply to young trees which have recently been inter-planted in orchards and which are required to make vigorous growth.

DO NOT apply by aircraft.






Foliar Sprays:

To a clean bucket of water add the required amount of FMC Repay and stir to make a smooth mix. Add slurry to half filled spray tank of clean water. Add the required amount of nonionic wetter (1000g/L) and agitate during the completion of filling. Frequent or constant agitation of the spray mixture is recommended. Wash out spray tank after use.


Collar Drench:

Mix required volume of FMC Repay with recommended volume of water. Periodic agitation may be necessary to prevent settling.




Foliar Sprays: Apply in a sufficient volume of water to ensure penetration of the spray and good coverage of target tissue, new green stem tissue in the case of apples. Apply in minimum volume of 1000L of water per ha. Non-ionic wetter (1000g/L) at 18mL/100L of water must be added to the final spray volume. It is not normally necessary to reapply the spray if rain follows soon after application.


Collar Drench:

Uptake of FMC Repay is most efficient when it is applied to soil which receives adequate water and where there is a high density of feeder roots. Apply required amount of FMC Repay in 0.5 to 2L of water per tree on to the soil/trunk crack line evenly around the base of the trunk. Where specific rates per tree are not given, the application rate per tree is determined by dividing the application rate per ha by the number of trees per ha. The volume of diluted drench required for even application without runoff will vary with the size of the tree and with soil type and moisture content. Use the higher volume on large trees.

Ensure that trees are adequately irrigated following treatment under dry conditions. Individual trees, which are smaller than average should be left untreated or given a proportionally smaller dose of FMC Repay.


Trickle Point:

Apply in 200-300mL water per tree beneath each trickle or dripper point or through the trickle irrigation system. Follow application with a short period of irrigation. Alternatively, the required amount of FMC Repay can be applied through the trickle irrigation system. Equal distribution of water between trees is essential for this method to give a uniform effect.




In some cases, control of growth may persist for more than one year. Retreat trees when normal growth resumes. Use the interval between the first treatment and the resumption of normal growth as a guide for retreatment in subsequent seasons.




FMC Repay is compatible with any of the following products: Nimrod+, Omite+ 300 W, Pirimor+ or Dithane+ M-45. However, mixing FMC Repay with more than any one of these products may give unpredictable results or may result in crop damage. If carbaryl is used as a thinning spray on apples, allow 21 days before application of FMC Repay.


Protection of wildlife, fish, crustaceans and environment


Do not contaminate streams, rivers or waterways with the chemical or used container.


Storage and Disposal


Store in the closed, original container in a cool, dry, well-ventilated place. DO NOT store for prolonged periods in direct sunlight. Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. Do not dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and deliver empty packaging to an approved waste management facility. If an approved waste management facility is not available bury the empty packaging 500mm below the surface in disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots, in accordance with relevant Local, State or Territory government regulations. Do not burn empty containers or product.


Safety Directions


Avoid contact with the eyes and skin. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water.
