Mainspring GNL Insecticide is a systemic anthranilic diamide insecticide formulated for the preventive control of a broad spectrum of chewing and sucking insect pests in greenhouse and nursery ornamental crops. The active ingredient is cyantraniliprole, classified under IRAC Group 28.
Product Configuration and Specifications
The product is defined by its active ingredient, formulation type, and commercial packaging. The active ingredient is cyantraniliprole. It is formulated as a liquid suspension concentrate. The standard commercial unit is a 1-pint container. These containers are packaged 8 per case, with 320 cases (2,560 containers) comprising a standard pallet.
Functional Mechanism and Design
Cyantraniliprole acts as a ryanodine receptor modulator. It binds to and activates insect ryanodine receptors, which are calcium channels in muscle cells. This activation causes an uncontrolled release of stored calcium, leading to impaired muscle contraction, paralysis, and ultimately insect death from feeding cessation. The compound is absorbed by plant roots and translocates systemically through the xylem, providing protection to new growth. It also exhibits translaminar movement.
Target Applications and Performance
The product is labeled for use on greenhouse and nursery-grown ornamental crops. It controls key pests including thrips, whiteflies, aphids, caterpillars, leafminers, leaf-feeding beetles, soft scales, and lace bugs. Performance is characterized by long-lasting residual control when used as a preventive soil drench, providing extended protection throughout crop production cycles and reducing the need for frequent foliar sprays.
Application Specifications and Protocol
The product is primarily applied as a soil drench but can also be used as a foliar spray.
Standard Application Protocol:
-
Soil Drench: This is the primary method for long-term preventive control. The product is mixed with water and applied directly to the potting media, where it is absorbed by the roots.
-
Foliar Spray: Used for corrective or supplemental control. Thorough coverage of plant foliage is required.
-
Timing: For preventive use, apply as a soil drench at planting or early in the production cycle. For foliar applications, apply at the first sign of pest presence.
-
Mixing: The suspension concentrate should be agitated in the spray tank to ensure uniformity.
Handling and Safety
Cyantraniliprole 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. Observe all re-entry intervals specified on the product label. Store in a secure, dry location away from foodstuffs and out of reach of children.
