数据库记载的用途

  • Used as pre- and post-emergence herbicide for control of annual broad-leaved weeds and some grasses in cotton, onions, potatoes, citrus and stone fruit, vines, lucerne, tea, and nuts; [HSDB]
  • Pre- and post-emergence control of annual broad-leaved weeds and some grasses incotton, garlic, onions, potatoes, citrus fruit, stone fruit, vines, lucerne, tea, and nut crops.
  • PRODUCED BY CYCLIZATION, WITH A HALOFORMATE, OF 1-(3,4-DICHLOROPHENYL)-1-HYDROXY-3-METHYLUREA, WHICH IS FORMED BY REACTION OF N-(3,4-DICHLOROPHENYL)HYDROXYLAMINE WITH METHYL ISOCYANATE.
  • METHAZOLE APPEARS TO BE A PROHERBICIDE WHILE DIURON & LINURON ACT DIRECTLY & VIA METABOLITES AS PHOTOSYNTHETIC INHIBITORS.
  • It is a selective herbicide effective against certain grasses and many broad-leaved weeds: pre-emergence in garlic and potatoes (1-2 kg ai/ha); as a directed spray on soil or emerged weeds in citrus, stone-fruits, nuts, tea and established vines (6 kg/ha) and on cotton 15 cm tall (1-2 kg/ha), onions (>2 leaves) (2.5 kg/ha), newly seeded or winter-dormant lucerne (>1 yr old) (2.25 kg/ha). It is preferably applied to moist soil; lower rates are applicable to light sandy soils.
  • LITTLE OR NO INTACT HERBICIDE WAS TRANSLOCATED FROM ROOTS TO LEAVES BUT RADIOACTIVITY IN LEAVES ACCOUNTED FOR 80-90% OF METHANOL-SOLUBLE LABEL @ 47 DAYS POSTTREATMENT. MOST OF THIS (14)C WAS RECOVERED AS DCPU /1-(3,4-DICHLOROPHENYL)UREA/ (50-60%) & UNIDENTIFIED POLAR METABOLITE (30-40%).
