Citation Insect Growth Regulator is a systemic insecticide formulated for the control of Dipterous leafminers, fungus gnats, and shore flies in ornamental and vegetable transplant production. The active ingredient, cyromazine, acts as an insect growth regulator (IGR) classified under IRAC Group 17.
Product Configuration and Specifications
The product is defined by its active ingredient, formulation type, and commercial packaging. The active ingredient is cyromazine. It is formulated as a wettable granule or soluble powder. The standard commercial unit is a single bag. These bags are packaged 8 per case, with 216 cases (1,728 bags) comprising a standard pallet.
Functional Mechanism and Design
Cyromazine is a chitin synthesis inhibitor absorbed by plant roots and translocated systemically through the xylem. It works by disrupting the molting process of target insect larvae. When larvae ingest treated plant material, cyromazine inhibits the formation of chitin, a critical component of the insect's exoskeleton. This prevents proper molting and leads to larval mortality before adult emergence.
Target Applications and Performance
The product is labeled for use on landscape ornamentals, container-grown ornamentals, greenhouse-grown ornamental crops, interiorscapes, and vegetable transplants grown for consumer use. It provides control of Dipterous leafminers (Liriomyza species), fungus gnats, and shore flies (in greenhouse and interiorscape settings only). Performance is characterized by the suppression of larval populations, breaking the lifecycle before adults can reproduce or cause further plant damage.
Application Specifications and Protocol
The product is applied as a soil drench or media incorporation for container crops, or as a spray for foliar application and soil surface treatment.
Standard Application Protocol:
-
Soil Drench/Media Incorporation: This is the primary method for controlling fungus gnat and shore fly larvae in the growing medium. The product is mixed with water and applied directly to the potting mix.
-
Spray Application: Used for foliar application to control leafminer larvae within plant tissue.
-
Timing: Applications should be made at the first sign of pest presence or as a preventative treatment based on scouting history.
-
Mixing: The product should be agitated in the spray tank to ensure even suspension and distribution.
Handling and Safety
The product requires careful handling. Applicators should wear appropriate personal protective equipment including long sleeves, long pants, chemical-resistant gloves, and eye protection. Avoid contact with skin, eyes, and clothing. Do not apply to plants intended for food crops, except as specified for vegetable transplants. Store in a secure, dry location away from foodstuffs and out of reach of children.
