- Coragen 20 SC is a concentrated suspension (SC) insecticide containing the active ingredient chlorantraniliprole at a concentration of 20% (200 g/L). It is specifically formulated to control Lepidopteran larvae, which are among the most dangerous pests of vegetable and fruit crops. It primarily works via ingestion with an additional contact action, affecting ryanodine receptors within the insect's muscles. This leads to an uncontrolled release of calcium within the muscle cells, causing the larva to stop feeding within minutes, then gradually become paralyzed and die within 24–60 hours. It is highly effective when applied to the early larval stages before the larvae enter the fruit. When incorporated into integrated pest management programs, it helps reduce direct damage and disrupt the pest's life cycle in the field.
Product Features
- A modern mechanism of action from the IRAC 28 resistance group reduces the risk of resistance development when used correctly.
- An immediate cessation of feeding within minutes protects the fruit and leaves from further damage.
- Strong efficacy against Tuta absoluta, armyworm, cotton leafworm, American bollworm, and leaf miners.
- Partial ovarian effect when applied early, which reduces the hatching rate in some species.
- Good stability on leaves with an extended effect that may last up to 14–21 days depending on weather conditions and growth density.
- It is relatively selective and has less impact on biological enemies compared to broad-spectrum pesticides when recommendations are followed.

A tip from Orchid
- The highest efficiency is achieved when spraying the first larval stages before they enter the fruit.
- No more than 2–3 consecutive treatments from the same resistance group are used during the season.
- It is preferable to exchange with different groups to avoid resistance developing.
- In cases of late or severe infection, it may be necessary to include it in an integrated program rather than relying on it alone.
- Adherence to dosages and prohibition periods is a fundamental condition to ensure crop safety and market quality.
