10) Appearance: Colourless powder, with a slight phenolic odour
11) Solubility.: In water 311 (pH1), 20031 (pH5), 23180 (pH7), 34196 (pH9) (all in mg/l, 25ºC); in ethanol 1250, diethyl ether 243, heptane 1.1, tolueme 6.7, xylene 5.8 (all in g/kg, 20ºC); in octanol 120 g/l (25ºC); insoluble in petroleum oils; mono-n-butylamine salt: in water 18 g/l(30ºC)

12) Stability: 2, 4-D is a strong acid, and forms water-soluble salts with alkali metals and amines; hard water leads to precipitation of the calcium and magnesium salts, but a sequestering agent is included in formulations to prevent this

 

 

Uses:

 

Selective systemic herbicide. Post-emergence control of annual and perennial broad-leaved weeds in cereals, maize, sorghum, grassland, established turf, grass seed crops, orchards (pome fruit and stone fruit), cranberries, asparagus, sugar cane, rice, forestry, and on non-crop land (including areas adjacent to water), at 0.28-2.3kg/ha. Control of broad-leaved aquatic weeds. The isopropyl ester can also be used as a plant growth regulator to prevent premature fruit fall in citrus fruit.
