Bayer Lesenta, a high-performance, broad-spectrum insecticide used primarily to control both sucking and chewing pests in various agricultural crops. It is a dual-active formula combining two powerful ingredients: Fipronil (40%) and Imidacloprid (40%).
Key Uses and Target Pests
Lesenta is highly regarded for its effectiveness against chronic pest problems, particularly white grubs in crops like sugarcane and groundnut.
- Target Pests:
- Sucking Pests: Aphids, whiteflies, jassids, thrips, and brown planthoppers.
- Chewing Pests: Caterpillars, root weevils, cutworms, stem borers, and leaf rollers.
- Target Crops: Common crops include rice (paddy), sugarcane, cotton, chili, groundnut, and various vegetables like mustard greens.
Mode of Action
Lesenta works through a dual mode of action, providing both systemic and contact/ingestion protection.
- Systemic Action: Imidacloprid is absorbed by the plant, providing long-lasting protection that doesn’t wash away easily after rain.
- Contact & Stomach Action: Fipronil acts rapidly on pests through direct contact or ingestion, interfering with their nervous system to cause paralysis and death.
