Travers

Mechanism of Action and Technical Profile

The efficacy of «Travers», produced by Agro Life Science Corporation (India), is based on the synergy between emamectin benzoate and the avermectin class. Unlike traditional contact insecticides, this formulation targets the neuromuscular transmission of pests at the cellular level. The active ingredient penetrates the leaf cuticle, forming a residual 'depot' within the plant tissue, which is essential for managing codling moths and leafrollers that often hide inside leaf folds or fruit tissues.

Technical Specifications and Performance

• Translaminar Activity: Upon application during the growing season, the active ingredient is rapidly absorbed into plant tissues. This provides protection even to plant parts that were not directly reached by the spray droplets.
• Paralytic Effect: By blocking GABA (gamma-aminobutyric acid) receptors, the formulation causes immediate cessation of feeding. Within hours, larvae become paralyzed, and complete mortality typically occurs within 1 to 3 days.
• Formulation: As a water-soluble powder, it ensures consistent concentration within the tank mix, preventing sedimentation and ensuring smooth operation of sprayer nozzles.

Operational Recommendations

Due to its systemic nature, strict adherence to the application protocol is required. The dosage rate ranges from 0.5 to 1.0 L/ha (based on active ingredient concentration). As the product falls under toxicity class 2, applications should be scheduled during early morning or late evening to minimize impact on non-target pollinators. The limit of 3 applications per season is crucial to prevent the development of pesticide resistance in pest populations, particularly the codling moth, which can adapt to repetitive chemical stress.

To achieve peak biological efficiency, the product should be applied during the period of mass larvae emergence. On apple orchards, uniform canopy coverage is vital, as the systemic movement of the active ingredient is the key factor in controlling pests sheltered within fruit cavities or leaf clusters.
