Chemistry:Esprocarb
Esprocarb is a thiocarbamate herbicide[1] used preёmergently and post emergently to control annual weeds and grasses, such as on paddy rice. It was introduced in 1988 in Japan[2]
Esprocarb mixes have been tested in Japan starting in 1985 for its effectiveness against cockspur grass (Echinochloa crus-galli), often mixed with the herbicide bensulfuron-methyl. Testing for esprocarb was meant to allow for a longer, residual control of weeds, eliminating the need for follow-up one-shot herbicide applications.[3]
It is usually sold as granules and has been marketed as "Fuji-Grass".[2]
Environmental behavior
Esprocarb is toxic to fish; its 96-hour LC50 for fish is 1.52 g/L.[4] It is not toxic to birds or mammals, with an -1">50 over 2000 mg/kg.[2] It has a GHS 'Toxic' mark,[4] though its low toxicity should exempt it.
It is non-mobile in soil and has a soil half-life of 50 days, making it moderately persistent.[2]
