Cyromazine Insect Growth Regulator
Cyromazine is a selective insect growth regulator used primarily against dipteran larvae. It is widely positioned for agricultural leafminer control, fly-larvae management in livestock environments and approved public-health applications.
As an IRAC Group 17 moulting disruptor, Cyromazine acts mainly on immature insect stages. It interferes with normal larval development, moulting, pupation and adult emergence. It is not designed to provide rapid knockdown of adult flies.
We supply Cyromazine in multiple concentrations and formulation systems to support different registration categories, application methods and distribution channels. Available options include technical material, wettable powder, soluble powder, water-dispersible granules, suspension concentrate, soluble concentrate, granules and selected veterinary premix products.

Suitable Applications
Agricultural Crop Protection
Agricultural Cyromazine products are mainly used for leafminer and other registered dipteran larval control.
Potential crop groups include:
- Cucumbers
- Beans
- Tomatoes
- Leafy vegetables
- Melons
- Potatoes
- Flowers
- Ornamental plants
- Protected crops
- Selected specialty crops
The most suitable formulation depends on the local label, application equipment, crop canopy and market preference.
Common agricultural specifications include:
- Cyromazine 50% WP
- Cyromazine 75% WP
- Cyromazine 50% SP
- Cyromazine 70% WDG
- Cyromazine 80% WDG
- Selected SC and SL products
For leafminer control, timing is more important than applying a high dose after severe damage has occurred.
Treatment should generally target:
- Initial adult activity
- First fresh mines
- Early larval stages
- Local economic thresholds
Uniform canopy coverage is important, especially on crops with dense foliage.
Livestock Hygiene
Fly breeding in poultry and livestock production is closely connected to manure moisture, bedding management and organic waste accumulation.
Cyromazine environmental products may be used in registered programs covering:
- Poultry houses
- Layer and broiler facilities
- Cattle housing
- Dairy operations
- Pig housing
- Calf pens
- Manure storage areas
- Wet bedding
- Farm waste collection zones
Environmental products are applied to the breeding substrate, not directly to animals.
Effective livestock fly management also requires:
- Regular manure removal
- Repair of leaking drinkers
- Reduction of wet feed accumulation
- Improved ventilation
- Bedding replacement
- Adult fly monitoring
- Rotation between larvicide modes of action
Public Sanitation
Cyromazine may also be included in approved public-health programs targeting fly larvae in organic breeding material.
Potential use sites may include:
- Refuse collection areas
- Waste transfer facilities
- Composting sites
- Public toilets
- Organic waste storage zones
- Other label-approved sanitation sites
Application should be directed at moist breeding material where larvae are actively developing.
Cyromazine should not automatically be promoted for:
- Open-water treatment
- Aquaculture environments
- Unrestricted sewage treatment
- General mosquito control
- Direct application to animals
- Food-contact surfaces
Any additional use must be supported by the locally approved label.
Veterinary and Feed-Through Programs
In some markets, Cyromazine is registered as a veterinary premix or water-soluble product for feed-through fly management.
After administration, a portion of the active ingredient or active residue reaches the manure, where it affects fly larvae developing in the waste material.
These products require specific controls covering:
- Veterinary or feed registration
- Approved excipients
- Species-specific directions
- Feed mixing uniformity
- Residue management
- Withdrawal periods
- Manufacturing standards
Agricultural WP, SC, WDG or TC products must not be added to animal feed or drinking water.
The active ingredient may be the same, but the formulation standard, impurities, carriers, regulatory category and residue requirements are different.

- Solvents or liquid carriers
- Agricultural surfactants
They must not be assumed suitable for animal feed or drinking water.
Public-Health Products
Public-health Cyromazine products are formulated and registered for environmental treatment of fly-breeding material.
The approved use sites, rates and precautions may differ from agricultural labels.
A crop-protection label does not automatically authorize use in manure, waste facilities or public sanitation sites.
Veterinary Products
Veterinary and feed-grade products require a separate standard.
Key controls may include:
- Suitable carriers
- Mixing uniformity
- Species-specific dosing
- Residue limits
- Withdrawal periods
- Feed or veterinary manufacturing requirements
Only registered veterinary products should be administered through feed or water.
Technical Material
Cyromazine technical material is intended primarily for industrial formulation.
It is normally supplied to:

Technical material should not be promoted as a ready-to-use field product without an approved end-use registration and label.
Application Guidance
Agricultural Application Timing
For leafminer management, Cyromazine should be applied during early infestation.
Recommended decision points include:
- Detection of adult leafminer activity
- Appearance of the first fresh mines
- Presence of early larval stages
- Local threshold recommendations
- Known seasonal pest pressure
Do not wait until most leaves are heavily mined.
Existing damage will remain visible after treatment. Field evaluation should focus on the number of new mines and the reduction in larval development.
Spray Coverage
Agricultural spray performance depends on uniform coverage.
Professional users should consider:
- Crop canopy density
- Leaf orientation
- Spray volume
- Nozzle selection
- Water quality
- Agitation
- Weather conditions
Both sides of the leaf may require attention, especially in dense vegetable and ornamental crops.
Manure and Breeding-Substrate Treatment
For hygiene applications, treatment should focus on the sites where larvae are actively developing.
Typical target zones include:
- Moist manure
- Wet bedding
- Spilled feed mixed with manure
- Organic waste
- Manure edges
- Areas around leaking drinkers
- Decomposing plant material
Applying the product only to clean walls or dry floors will not control larvae developing deeper in organic matter.
Integrated Fly Management
Cyromazine performs best when combined with operational hygiene measures.
A practical program may include:
- Frequent manure removal
- Reduction of excess moisture
- Repair of water leaks
- Waste-management schedules
- Fly monitoring
