Introduction
Chlorantraniliprole, also known by trade names such as Coragen and Rynaxypyr, is one of the most widely used insecticides globally. It is known for its high efficiency and broad-spectrum activity against a variety of pests. In this guide, we will explore its mechanisms of action, applications, and proper usage techniques.
Mechanisms of Action
Chlorantraniliprole works by activating the ryanodine receptors in insect muscle cells, causing an uncontrolled release of calcium ions. This leads to muscle paralysis and ultimately the death of the insect. Even at low doses, it provides reliable and stable pest control. The insect stops feeding almost immediately after application, and the product remains effective even after rain due to its strong adherence to plant surfaces.
Applications and Uses
1. Pest Control
Chlorantraniliprole is effective against a wide range of pests, including:
-
Armyworms
-
Helicoverpa spp. (Cotton bollworm, Corn earworm)
-
Diamondback moth
-
Tomato pinworm
-
Codling moth
-
Oriental fruit moth
-
Peach twig borer
-
European corn borer
-
Fall armyworm
-
Leafrollers
2. Best Practices for Application
For optimal results, apply chlorantraniliprole under the following conditions:
-
Early in the morning or late in the afternoon to reduce evaporation and improve absorption.
-
Ensure thorough coverage of all plant surfaces.
-
Adhere to the recommended dosage rates and application intervals to prevent resistance buildup.
Specific Application Instructions
1. Rice
To control rice pests like the rice stem borer, use 20% chlorantraniliprole suspension concentrate at a rate of 5-10 milliliters per acre, diluted in water. Apply as a foliar spray for even coverage.
2. Vegetables
For pests such as the diamondback moth in vegetables, use 5% chlorantraniliprole suspension concentrate at 30-55 milliliters per acre, diluted in water. Apply as a foliar spray.
3. Fruit Trees
For pests like the codling moth in fruit trees, dilute 35% chlorantraniliprole in water at a ratio of 1:17500 to 1:25000, and apply as a foliar spray.
Safety and Environmental Considerations
Chlorantraniliprole is considered safe for non-target organisms, including beneficial insects and wildlife, when used according to label instructions. However, it is essential to follow all safety guidelines and wear appropriate protective gear during application.
Conclusion
Chlorantraniliprole is a powerful tool in integrated pest management programs due to its broad-spectrum efficacy and safety profile. Proper application techniques and adherence to best practices will ensure effective pest control and prolonged efficacy of this valuable insecticide.
