Thiamethoxam was discovered in 1991, and it was first registered in New Zealand in 1997. The three pesticides were found to impact bee learning and navigation and reproduction, though the risk varies with route of exposure and between bee species. Thiamethoxam can be used as a foliar application, a soil treatment, and a seed treatment. The active ingredient also gives plants the ability to overcome both biological and physiological stresses, which has been demonstrated even during challenging environmental conditions. The activity of thiamethoxam, or any insecticide, at the - per specific active substance and product-type combination (use the Search tab); and - as a summary of all product-type applications that have been submitted for a given active substance (Summary tab). Nicotine is naturally found in many plants, including tobacco, and is toxic to insects. The active ingredient, thiamethoxam, protects plants against pests during the plants' most vulnerable period – the first 30 to 40 days of growth. Once inside the plant, thiamethoxam is slowly metabolized, resulting in extended residual control. On April 2018, the European Union prohibited outdoor uses of Thiamethoxam and two other neonicotinoids: clothianidin and Imidacloprid. Within hours of contact or ingestion of thiamethoxam, insects stop feeding. Thiamethoxam treated plants can better cope with environmental stress and this is the reason why many growers see more pronounced differences between plants treated with thiamethoxam versus untreated or competitive products. What evidence is available to … The technical reports update initial conclusions drawn up in 2013. Thiamethoxam is a second generation neonicotinoid compound that belongs to the chemical subclass thianicotinyls. The ban inhibited use of Thiamethoxam (for plants that attract bees) and other nicotine-based products. Thiamethoxam: For control of aphids, whitefly, thrips, ricehoppers, ricebugs, mealybugs, white grubs, Colorado potato beetle, flea beetles, wireworms, ground beetles, leaf miners and some lepidopterous spe cies, at application rates from 10 to 200 g It works by use of the insects' acetylcholine receptors, making is selectively toxic to insects but not mammals. Thiamethoxam interferes with nicotinic acetylcholine receptors in the insect’s nervous system, which are essential for proper functioning of the nerves. Imidacloprid is an insecticide that was made to mimic nicotine. Death usually occurs within 24 to 48 hours. It has been used in products sold in the United States since 1994. Thiamethoxam is a group 4A, a neonicotinoid insecticide. Some neonics are used on fruiting trees in Europe. New reports came in 2018 suggesting that most neonicotinoids threaten wild bees and honey bees’ populations. Imidacloprid is used to control sucking insects, termites, some soil insects, and fleas on pets. The review looked at imidacloprid, clothianidin and thiamethoxam.

ACTARA® is highly systemic and well suited for application as a foliar spray, drench or drip irrigation. ACTARA belongs to a new chemical class neonicotinoids, used for the control of Aphids, Whitefly & Jassids (sucking pests) ACTARA is a robust insecticide which is fast acting and therefore rapidly taken up by the plants, in any situation Main Benefits of Using ACTARA®: ACTARA® is highly effective at low use-rates against a broad spectrum of sucking, soil and leaf-dwelling pests.
