6 GENERAL DESCRIPTION:Metolachlor is a root and leaf absorbed translocated herbicide. It will control many grasses and some broadleaved weeds. Its main use is for pre-emergent weed control in cereals. It presents little hazard to the environment.
7 APPLICATION METHODS AND TIPS:Metolachlor is normally applied to bare soil or in combination with a knock down herbicide. Rainfall is important to wash the herbicide from plant residue into the soil. High plant residue levels may reduce weed control (eg. 4 t/ha wheat straw reduced weed control by 20%). For grass weed control, the ideal placement for metolachlor is just above the germinating seeds. Deeper incorporation appears beneficial for broadleaved weed control. This may be due to metolachlor being more efficiently absorbed by shoots and cotyledons of grasses compared to roots and vice versa for broadleaved species. Metolachlor should not be applied to wetlands.
24 TOXICITY:Mammalian toxicity - low.
20 MODE OF ACTION:Metolachlor is absorbed by the roots and young leaves of all germinating plants. It moves mainly in an upward direction and inhibits plant growth. The primary biochemical mechanism is unknown. Growth inhibition is due to a reduction in both cell division and enlargement. Longitudinal growth is reduced more than lateral growth. This results in a compact appearance of affected roots. Protein and fat synthesis, respiration, lignification and anthocyanin production are reduced. Hormonal effects also occurs resulting in hormone like symptoms.
23 PLANT SYMPTOMS:Seeds normally germinate but often fail to emerge. Seedlings that do emerge have stunted and abnormal growth. The first leaf may fail to unfold. Roots are stunted and compact. Leaf senescence may be delayed.
27 ENVIRONMENTAL FATE:Metolachlor is degraded mainly by microbes in the field. The half life is normally 3 to 8 weeks and may be up to 12 weeks under cold, dry conditions in silty soils. The half life is usually longer in clay loams than sandy loams which is contrary to most other herbicides.
31 PROPERTIES:Solubility - 530 mg/L in water.
