Glyphosate plus Hammer
3 ACTIVE INGREDIENTS: Glyphosate 450g/L plus carfentrazone 240g/L

Formulation: Water soluble

4 CHEMICAL GROUP: M,G

Inhibitor of EPSP synthase and inhibitor of protoporphyrinogen oxidase.

6 GENERAL DESCRIPTION:

The addition of Hammer to glyphosate hastens the onset of visual symptoms and improves the control of several weeds such as Mallows, Clovers, Spiny Emex (Doublegee) and Wild Radish.

See individual products for further information.

7 APPLICATION METHODS AND TIPS:

Apply in fine weather when plants are actively growing.

Drought or nitrogen stressed plants are difficult to kill with glyphosate.

If plants have been heavily grazed or defoliated they should be allowed to regrow until the root:shoot ratio is around 1 before application of herbicide or the rate of herbicide may need to be increased to achieve effective control.

14 HERBICIDE RESISTANCE:

Repeated applications are likely to lead to resistance.

15 REPLANTING INTERVALS:

CropTime
Most cropsA few hours to a few days.

16 WITHHOLDING PERIODS:

20 MODE OF ACTION:

Hammer causes brown out to occur more quickly than when glyphosate is used on its own. The effect of Hammer in destroying photosynthetic tissue probably reduces the likelihood of regrowth.

Selectivity:

Non selective.

23 PLANT SYMPTOMS:

Chlorosis of the leaves is usually seen within a few days and this is followed but necrosis and death within a few weeks.
