Chlorantraniliprole is a modern insecticide that falls under the anthranilic diamide chemical group; it is commonly used in controlling a wide range of lepidopteran insect pests like the caterpillar, borers, armyworms, and leaf miners. It works by acting on ryanodine receptors in insect muscle cells, causing a fainting paralysis and ultimately causing death. Chlorantraniliprole causes selectivity on pests and avoids harm to other beneficial organisms, and is an effective component of integrated pest management.
Chlorantraniliprole is provided in various formulations, such as suspension concentrate (SC), popular 18.5% SC, water-dispersible granules (WDG), and granular forms, which allow the choice of many crops and application methods.

Conclusion
While Chlorantraniliprole and its various formulations, including the widely used 18.5% SC, remain highly effective options for managing caterpillars and related pests, alternatives exist that can suit different crop and pest scenarios. Choosing the right insecticide depends on pest species, resistance profiles, environmental considerations, and crop type. Integrated pest management strategies often incorporate multiple modes of action to sustain efficacy and reduce resistance risks.
