Dinotefuran vs Thiamethoxam: Choosing a Neonicotinoid
Both are systemic neonicotinoid insecticides. They share a mode of action but differ in speed, spectrum, and formulation fit. This guide helps you pick the right one for your market.
Two Neonicotinoids, Different Profiles
Dinotefuran and thiamethoxam both belong to the neonicotinoid class. They act on insect nicotinic acetylcholine receptors, disrupting nerve signaling. Both move systemically in the plant, which helps reach pests that feed on sap or hide in new growth.
Dinotefuran is often used where fast knockdown matters. It's common in rice, vegetables, and fruit trees against hoppers, aphids, and thrips. Thiamethoxam appears in similar crops but is also widely used in soil and seed treatments. You'll see it in many broad-spectrum programs.
Side by Side: Dinotefuran vs Thiamethoxam
| Aspect | Dinotefuran | Thiamethoxam |
|---|---|---|
| Chemical class | Neonicotinoid (furanicotinyl) | Neonicotinoid (thianicotinyl) |
| Mode of action | Nicotinic acetylcholine receptor agonist | Nicotinic acetylcholine receptor agonist |
| Main targets | Hoppers, aphids, thrips, whiteflies, some beetles | Aphids, whiteflies, hoppers, soil pests, early-season pests |
| Systemic or contact | Systemic with some contact activity | Systemic, strong root uptake |
| Typical formulation | SC, WDG, often in mixtures | SC, WG, FS for seed treatment |
| Resistance management role | Useful in rotation with non-neonicotinoids | Useful in rotation; avoid consecutive neonicotinoid use |
| Tank-mix notes | Commonly mixed with pyrethroids or pymetrozine | Often mixed with fungicides or other insecticides |
When to Pick Each Active
Pick dinotefuran when you need quick knockdown on hoppers or thrips in rice, tea, or vegetables. It's a good fit for foliar sprays where fast visible control helps the grower. Thiamethoxam often suits preventive programs, especially as a seed or soil treatment, because of its strong root uptake.
CHICO offers dinotefuran in several ready formulations. DITO combines dinotefuran 10% with tolfenpyrad 15% as an SC. BLINK pairs dinotefuran 12% with bifenthrin 18%. PADAN mixes dinotefuran 10% with pymetrozine 40% in a WDG. These are options if your market prefers dinotefuran-based products.
Questions Buyers Ask
Which one works faster, dinotefuran or thiamethoxam?
Dinotefuran generally shows faster knockdown on contact and through ingestion. Thiamethoxam may take longer to show full effect, especially when used as a soil or seed treatment. Check the label of your registered product for expected speed.
Can I use dinotefuran and thiamethoxam in the same program?
You can, but avoid using them back to back against the same pest generation. Both are neonicotinoids with the same target site. Rotate with a different mode of action to slow resistance development.
Which is better for rice hoppers?
Both control hoppers. Dinotefuran is common in foliar rice sprays. Thiamethoxam is often used in nurseries or as a seed treatment. Your choice depends on application timing and local registration. Confirm with your registrant.
