Dinotefuran is a systemic insecticide of the neonicotinoid class, in the nitroguanidine sub-class. These include other chemicals like nithiazine, imidacloprid, thiacloprid, thiamethoxam, nitenpyram, accetamiprid and clothianidin.
Dinotefuran appears as white to off-white powder or crystals and is highly soluble in water. It is a neurotoxin that disrupts the insect’s nervous system function by inhibiting nicotinic acetylcholine receptors. It is used to control insect pests, such as whiteflies, thrips, leafhoppers, aphids, mealy bugs, stink bugs, leaf miners, ants, cockroaches, fleas, flies, crickets and gnats.
Dinotefuran is the common name for (EZ)-(RS)-1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine. It has a molecular formula of C7H14N4O3. It is under patent in many countries including Australia, China, EU, Indonesia, Japan, Switzerland, and the U.S.
Dinotefuran is harmful if swallowed, as per the online chemistry database PubChem.
Mild to moderate poisoning can cause the following side effects:
Severe poisoning may cause agitation, seizures, metabolic acidosis, coma, hypothermia, pneumonitis, respiratory failure, hypotension, ventricular dysrhythmias, and death.
The United States Environmental Protection Agency (EPA) classified dinotefuran as “not likely to be a human carcinogen.”
Dinotefuran appears to have the potential to leach through soil and contaminate groundwater and drinking water.
Dinotefuran is nontoxic to birds, mammals, fish and algae, but it is highly toxic to marine/estuarine mysid shrimp. In addition, it is highly toxic to honey bees by all routes of administration.
Dinotefuran is classified as Category III, a moderate skin irritant and at least mild or moderate irritation could result from accidental eye exposure. Dinotefuran may also cause some neurotoxic, immunotoxic and reproductive effects.
Dinotefuran is applied to a wide range of plants and crops such as cantaloupe, melons, watermelons, grapes, bell peppers, tomatoes, broccoli, cauliflower, celery, leaf lettuce, head lettuce, cabbage, Brussels sprouts, Chinese cabbage, bok choy, eggplants, cucumbers, summer squash, parsley, spinach and cotton. It also applied to greenhouse plants and flowers.
It is advisable to avoid products that use dinotefuran as an active ingredient, such as MTI-446, to prevent any form of contact or exposure. Handlers, mixers and applicators of dinotefuran may be exposed to its fumes in the workplace. The following are some preventive measures to avoid any contact with dinotefuran:
Dinotefuran is a systemic, neurotoxic insecticide.
Dinotefuran is used to control insect pests, such as whiteflies, thrips, leafhoppers and aphids, to name a few.
Dinotefuran is harmful when ingested, and is highly toxic to honey bees.
