Kills cutworms, the larval stage of various moths, are destructive pests that damage crops by cutting down young plants at the soil level. Malathion, an organophosphate insecticide, is effective in controlling these pests. Here’s how it works:
Malathion Mechanism of Action
- Contact and Ingestion Poison:
- Absorption: Cutworms absorb malathion through contact or ingestion.
- Enzyme Inhibition: Malathion inhibits acetylcholinesterase, leading to the accumulation of acetylcholine, a neurotransmitter. This causes continuous nerve stimulation.
- Nervous System Disruption:
- Overstimulation: The buildup of acetylcholine overstimulates the nervous system, causing muscle spasms, paralysis, and death.
Application Guidelines
- Timing:
- Early Intervention: Apply at the first sign of activity.
- Evening Application: Maximize effectiveness by applying in the late afternoon or early evening.
- Method:
- Spray Application: Ensure thorough coverage of plants and soil.
- Soil Treatment: Treat soil around plants for severe infestations.
Advantages of Malathion
- Broad-Spectrum: Effective kills cutworms.
- Rapid Action: Quickly reduces crop damage.
- Cost-Effective: Affordable for large-scale use.
Malathion is a powerful tool for managing cutworm infestations and protecting crops. Always use responsibly, following safety and environmental guidelines.
