Chemical Classification and Rapid Mode of Action
Dinotefuran represents an advanced neonicotinoid molecule engineered with a unique tetrahydrofuran ring structure.
- Chemical Class: Third-generation furanicotinyl neonicotinoid, classified under IRAC Group 4A (nicotinic acetylcholine receptor competitive modulators).
- Unique Chemical Feature: Lacks a chlorine atom, distinguishing it structurally from older neonicotinoids like Imidacloprid and Acetamiprid, which allows it to control insect populations showing cross-resistance.
- Rapid Neurotoxic Action: Binds to insect nicotinic receptors, inducing continuous nerve firing, immediate cessation of feeding within hours, paralysis, and death.
- Translaminar and Acropetal Movement: Quickly absorbed by leaves and translocated upward, controlling pests concealed on lower leaf surfaces and inside plant canopies.
Target Crops and Controlled Pest Complex
Dinotefuran is officially registered for controlling devastating sap-feeding insects across staple and commercial crops.
- Paddy (Rice): High-efficacy control of Brown Plant Hopper (Nilaparvata lugens) and White Backed Plant Hopper (Sogatella furcifera), halting hopper burn in dense paddy stands.
- Cotton: Controls resistant jassids, aphids, and whiteflies, preventing sooty mold development and protecting boll retention.
- Chili and Tomato: Controls thrips and whiteflies, curtailing the transmission of viral leaf curl diseases.
- Cucurbits and Vegetables: Controls leafhoppers and sucking bugs during early vegetative and flowering stages.
- Formulation (20% SG): Water-soluble granules dissolve instantly without foaming, leaving zero nozzle residue in spray equipment.
Label Directions, Spray Safety and Resistance Management
Proper application timing and rotation preserve chemical efficacy and safeguard non-target organisms.
- Application Timing: Apply when insect scouting indicates pest populations approaching the Economic Threshold Level (ETL), targeting the base of plants in paddy for hopper control.
- Spray Volume: Use sufficient water per hectare with a hollow-cone nozzle to ensure thorough coverage of lower stem and leaf zones.
- Pollinator Protection: Do not spray blooming crops during hours of active bee foraging, as neonicotinoids are toxic to honeybees.
- Pre-Harvest Interval (PHI): Strictly follow statutory waiting periods between final application and harvest as stated on the registered CIBRC container leaflet.

Common questions
What is Dinotefuran 20% SG primarily used for in paddy crops?
Dinotefuran 20% SG is primarily used for the rapid knockdown and control of Brown Plant Hopper (BPH) and White Backed Plant Hopper (WBPH) in paddy.
How does Dinotefuran differ from older neonicotinoids like Imidacloprid?
Dinotefuran has a unique furanicotinyl molecular structure that provides faster systemic absorption, quicker feeding cessation, and efficacy against pest biotypes resistant to older neonicotinoids.
Where should the spray be directed when treating BPH in paddy?
For BPH management, direct the spray nozzle toward the lower stem base of the paddy plants where hoppers congregate and feed.
