6 GENERAL DESCRIPTION:A selective, pre emergence herbicide for control of some grasses and broadleaved weeds used mainly beans, maize, poppies and pumpkins.
Developed from propachlor in the 60's, to alachlor in the 70's, to metolachlor in the 80's to dimethenamid in the 90's
7 APPLICATION METHODS AND TIPS:Best results when applied to moist, weed free soil with a fine tilth and little trash and rain follows a day or two after spraying.
6-13 mm rain is usually required for ideal activation. Incorporation with irrigation should not exceed 25-50 mm.
8 WEATHER:Rainfast immediately for pre emergent applications. Probably rainfast in 2-4 hours for treatment of small Fumitory seedlings.
Frost effects: None.
Wind: Avoid spraying when wind is toward water bodies or sensitive plants within 20-50 m of sprayed area.
Inversions: Avoid application during low level inversions as excessive drift may occur.
Temperature: Little effect.
Delta T and relative humidity: Avoid application when Delta T is greater than

13 SPRAYER DECONTAMINATION:Clean Up:
Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.
Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through boom.
Remove filters and clean separately.
Rinse with water and drain.
Quarter fill the tank with an alkali detergent (eg 500 mL or g of Drive, Dynamo, Omo, or Surf per 100 L water) and circulate for at least 15 minutes then run through boom. Rinse with water. Remove filters and clean separately. Replace them and rinse the whole system with water again.

19 SOIL:Soil texture:
Injury to green beans, kabocha, green peas, pumpkins, corn and sweet corn may occur at label rates on soils with very low cation exchange capacity (CEC). Soils containing low levels of clay and organic matter normally have a low CEC. Do NOT apply to green beans, kabocha, green peas, pumpkins, corn or sweet corn crops grown on soils with a cation exchange capacity (CEC) of less than 5
meq / 100g (or cmol / kg) OR soils with a clay content of less than 10 % AND organic carbon content of less than 2%.
