Metham controls certain soil-borne pests including onion weed (Western Australia only), nematodes, symphylids and fungus diseases.
Advantages Metham is used as a soil fumigant before planting ornamentals, food and fibre crops and tobacco.
Refer to label for all instructions and directions for use.
Cleaner soil free from disease, and fungi which results in increased yield and cleaner crops.
Mode of Action
General Instructions Mixing
After mixing with water do not allow mixture to stand.
Soil should be carefully prepared in advance according to the directions given in tables. Cultivate the area thoroughly and break up clods.
Loosen soil deeply one week in advance of application. Soil should be kept moist until application, and if soil has not crusted in the meantime, re-cultivate lightly. Soil temperature should be in the range 10C-32C to depth of 8cm. Where fumes become unpleasant spray with water to seal fumes in.
Intervals for Cultivation and Planting After Application
Planting may take place 14-21 days after application if soil is light-medium texture, if not excessively wet or cold. A minimum interval of 30 days is necessary where soil texture is heavy or high in organic matter, or is wet or soil is less than 15C.
A 60 day interval is required if application rate is greater than 1100L/ha. Cultivation should be carried out on wet, heavy soils to prevent crusting and promote drying, 5-7 days after application, and may be repeated when necessary.
DO NOT mix treated soils with untreated soils. Sow an indicator crop to test that no toxic NUFARM METHAM remains in the soil, approximately 7 days before main crop.
Lettuce or radish is suitable for this purpose because of their rapid germination process. Check for root damage which will indicate whether or not soil is still toxic.
Heavy potting soil or heavy field soil, including soils high in clay or organic matter, ensure that proper aeration and drying of the soil takes place.
DO NOT USE BY HAND DIRECTED SPRAYING INCLUDING SPRINKLER CAN.
DO NOT TREAT POTTING SOIL BY LOOSE MIXED METHOD OR VIA SHREDDER.
DO NOT USE BY FLOOD IRRIGATION OR OVERHEAD SPRINKLER SYSTEMS.
Workers previously experiencing skin or respiratory tract irritation from metham-sodium or dazomet exposure should not work with metham-sodium products. After mixing with water do not allow mixture to stand as poisonous fumes are released on standing.
Workers manually sealing should wear the personal protective clothing specified for applicators.
Do not allow entry into treated areas for 48 hours. When prior entry is necessary, wear personal protective equipment specified for applicators. Clothing must be laundered after each day's use.
Greenhouse Application, Including Under Plastic
Do not allow entry into treated areas for 7 days. When prior entry is necessary, wear personal protective equipment specified for applicators. Clothing must be laundered after each day's use. Thoroughly ventilate greenhouse for 24 hours after removing plastic
Re-Handling Period - Potting Soil
Treated soil is to remain covered by plastic sheeting or similar material impermeable to MITC, for 7 days after treatment. When prior handling is necessary, wear personal protective equipment specified for applicators. Clothing must be laundered after each day's use.
