- SUSPENSION CONCENTRATE
Transform Isoclast active Insecticide is a suspension concentrate formulation containing 240 g/L of the active constituent sulfoxaflor. It is designed to target sap-sucking insect pests in major Australian horticultural crops, including tree fruits, citrus, avocados, macadamias, and viticulture blocks.
Positioned as an effective option for controlling difficult sap-feeding pests such as mealybugs, scale, thrips, and fruit spotting bugs, it operates effectively across key growing regions from Sunraysia and the Riverland to the Goulburn Valley, Northern Rivers, and Atherton Tableland. Its rapid knockdown and translaminar movement fit well into standard orchard and vineyard spray programmes.
When incorporated into commercial pest management strategies, growers should align application timing with pest monitoring, local canopy growth stages, and resistance management recommendations as detailed on the registered label.

GRAZING AND STOCKFOOD WITHHOLDING PERIODS (WHP): Pineapple: DO NOT GRAZE OR CUT FOR STOCKFEED FOR 1 DAY AFTER APPLICATION. Forage brassicas: DO NOT GRAZE OR CUT FOR STOCKEED FOR 7 DAYS AFTER APPLICATION. Canola forage, post-harvest straw and stubble, cereals and pulses: DO NOT GRAZE OR CUT FOR STOCKFEED FOR 14 DAYS AFTER APPLICATION. Lucerne: DO NOT GRAZE OF CUT FOR STOCKFEED FOR 21 DAYS AFTER APPLICATION. Cotton: DO NOT FEED COTTON TRASH TO ANIMALS Soybeans: DO NOT GRAZE OR CUT FOR STOCKFEED FOR 7 DAYS AFTER APPLICATION. Sweet corn: DO NOT GRAZE OR CUT FOR STOCKFEED FOR 7 DAYS AFTER APPLICATION. EXPORT SLAUGHTER INTERVAL (ESI) ? 14 days: After observing the grazing withholding period, livestock that has been grazed on or fed treated crops should be placed on clean feed for 14 days prior to slaughter. CROPS FOR EXPORT - Before using Transform? on crops destined for export it is essential to consult your exporter or Corteva Agriscience to ensure that an appropriate MRL is in place in the importing country.
Withholding periods vary by crop type and end use. Harvest WHPs range from nil or not required when used as directed (such as in macadamias and wine or table grapes), to specific short intervals for citrus and tropical fruits, up to longer harvest intervals for pome fruit, avocados, and broadacre grain crops. Specific grazing withholding periods and export slaughter intervals (ESI) apply to fodder, sweet corn, lucerne, and pasture crops fed to livestock. Before harvesting produce or grazing animals, consult the label WHP table to ensure full compliance with target market MRLs.
Mode of action
Sulfoxaflor belongs to IRAC Group 4C (sulfoximines). It acts as an agonist at insect nicotinic acetylcholine receptors (nAChR), binding to target sites in the central nervous system to disrupt nerve impulse transmission, leading to paralysis and pest death. It demonstrates systemic and translaminar movement within plant tissues, ensuring thorough delivery to sap-feeding insects feeding on non-sprayed leaf surfaces.
Resistance management
To delay the development of insect resistance to IRAC Group 4C insecticides, alternate this product with effective insecticides from different mode-of-action groups. Avoid consecutive applications over multiple generations of fast-breeding pests such as mealybugs, scale, or thrips. Always observe the maximum seasonal application limits specified on the registered label to maintain active constituent efficacy across your orchard or paddock.
Tank-mix compatibility
Sulfoxaflor suspension concentrate formulations are generally compatible with many common fungicides and insecticides. However, caution is required when tank-mixing with crop oils or foliar fertilisers, particularly during high-temperature conditions or on sensitive crop growth stages. Always conduct a physical jar test to confirm tank mix stability prior to broad-acre or orchard application, and consult the approved label for specific compatibility warnings and plant safety notices.
Handling and environment
Handle with care and observe standard safety precautions listed on the product container. Avoid spray drift onto non-target areas, aquatic habitats, adjacent paddocks, or neighboring crops. Sulfoxaflor is toxic to insects, so timing of application relative to flowering and pollinator activity is critical to protect honeybees; refer directly to the approved label for mandatory pollinator safety instructions, buffer zones, re-entry periods, and required personal protective equipment (PPE).
Common questions
- How does sulfoxaflor move within the target plant canopy?
- Sulfoxaflor moves via translaminar activity through leaf layers and exhibits systemic uptake, helping reach pests feeding on leaf undersides or sheltered canopy crevices.
- What should I consider regarding honeybees when planning an application?
- Because the active constituent targets insect pests, applications must be carefully managed relative to crop bloom and pollinator activity. Always consult the approved label for specific directives on bee safety and spray timing around flowering.
- How do I determine correct water volumes and spray rates for tree crops?
- Application rates and water volumes depend on canopy size, sprayer setup, and target pest density. Consult the directions for use table on the approved product label to calculate the correct dilution for your specific canopy architecture.
- Where does this product fit within an integrated pest management (IPM) strategy?
- Its targeted spectrum against sap-sucking pests like scale, mealybugs, and thrips allows for selective control. Refer to local IPM guidelines and the label to assess impacts on specific beneficial predatory insects.
- What steps are required if harvested produce is destined for export markets?
- Maximum Residue Limits (MRLs) differ between destination countries. Verify that appropriate MRLs exist in your target export market by consulting your packer, exporter, or Corteva Agriscience prior to application.
