Documented Uses

• Selective herbicide, absorbed by the roots and foliage. Inhibits photosynthesis. Effective both as a residual soil-acting herbicide and a contact foliar-spray against many broad-leaved and grass weeds of winter cereals, especially against Alopecurus myosuroides.
• PRODUCED BY THE ACTION OF 3-CHLORO-P-TOLYL ISOCYANATE WITH DIMETHYLAMINE...
• Urea, N'-(3-chloro-4-methylphenyl)-N,N-dimethyl-: ACTIVE
• IT WAS INTRODUCED, IN 1969, BY CIBA AG...UNDER CODE NUMBER C2242, TRADE MARK DICURAN & PROTECTED BY BELGIAN PATENT 728267. ITS HERBICIDAL PROPERTIES WERE FIRST DESCRIBED BY L'HERMITE Y ET AL; CR JOURN ETUD HERBIC CONF, COLUMA, 5TH, 1969, II, 349.
• IT IS EFFECTIVE BOTH AS RESIDUAL SOIL-ACTING HERBICIDE & AS CONTACT FOLIAR-ACTING SPRAY AGAINST GRASS WEEDS & MANY BROAD-LEAVED WEEDS OF CEREAL CROPS, PARTICULARLY AGAINST BLACK GRASS (ALOPECURUS MYOSUROIDES). IT IS USED ON WINTER CEREALS IMMEDIATELY AFTER SOWING AT 1.5 TO 3 KG AI/HA; FOR POST-EMERGENCE, AT SAME RATES WHEN CEREAL IS AT THE 3-LEAF STAGE TO END OF TILLERING. IT IS COMBINED WITH MECOPROP (LUMETON FORTE) TO IMPROVE THE CONTROL OF GALLIUM, VERONICA & PAPAVER SPP.
• Not marketed in the United States.
