Fluchloralin is a pre-emergent dinitroaniline herbicide, introduced in 1972, and used to control broad-leaved weeds and annual grasses. It is used in India.[1][2] In other countries, it might be considered obsolete.[1] 71 tonnes of fluchloralin was sold in India in fiscal year 2009–2010.[2]

Fluchloralin's resistance class is D (Australia), K1 (global) or 3 (numeric); its mode of action is inhibition of microtubule formation.[1]

Usage

It has been sold as a 45% emulsifiable concentrate, and applied at rates of 0.75 to 1.5 kg/ha of active ingredient.[2]

Fluchloralin has been used on peas, beans, cotton, okra, sunflowers, soybean and peanuts.[1]

Environmental behaviour

It can persist for 3 to 6 months in soil,[2] with a half-life of 76 days. In water, photolysis degrades it rapidly, with a half life of half an hour.[1]

Tradenames

It has been sold as Basalin (BASF), Dhanulin (Dhanuka Agritech), Nagflur (Multiplex), Anulin (Anu), Vicolin (Ghujarat Krishi), Herbilin (Herbicide India) and Flight (Devidayal).[2]
