ActivityInsecticide.
Dinotefuran can be applied to foliage or to the soil and is active by contact and ingestion. It also has root-systemic activity. The products activity persists for up to several weeks after application.
Dinotefuran has demonstrated no cross-resistance to organophosphates, carbamates, pyrethroids and insect growth regulators. Mitsui recommends its use in both resistance management and integrated pest management systems. In tests against several strains of mosquito species, although it was generally less toxic than standards, dinotefuran was more effective against a carbamate-resistant strain of Culex quinquefasciatus than the susceptible strain (J Med Entomology, 2004).
Data from Mitsui indicate that dinotefuran provides superior control of stinkbugs, fruit moths, flea beetles and leaf miners compared with imidacloprid.
Field trials conducted on golf courses in Mississippi in 2000 with dinotefuran (code numbered YW-74G) demonstrated a comparable level of control of mole crickets (Scapteriscus spp) to the reference product, orthene. -

Fate in aquatic systems:
Hydrolysis at 20C; dinotefuran is stable in water at pH 4, 7 and 9.
Aqueous photolysis; photolytic degradation in sterile buffer gave a DT50 of 1.7 days at Summer latitude 30N and 18.60 days at winter latitude 50N.Fate in soil:
In aerobic laboratory soil metabolism studies on loamy sand soil, the DT50 value was 51.7 days.
In a 320 day aquatic water-sediment system, the DT50 value for dinotefuran in the aerobic water phase was 23-49 days and 45-128 days in the largely anaerobic sediment layer.
Field dissipation studies in sandy loam soils in the US gave DT50 values of 68.6 days in California (pH 8.8), 22.6 days in Georgia (pH 6.5) and 59.2 days (pH 6.6). -
