6 GENERAL DESCRIPTION:

A contact, non residual herbicide.

7 APPLICATION METHODS AND TIPS:

10 WATER QUALITY:

Hard water - There may be a slight loss of activity due to ionic bonding in very hard water.

Colloids - Significant loss of activity as the amount of clay in the water increases. If it is difficult to see a coin on the bottom of a 10 litre bucket full of water then the water should be cleared or an alternate source found.

pH -Acidic water is usually OK. Highly alkaline water may cause loss of efficacy.

11 COMPATIBILITY:

Trace elements.

Zinc sulphate and copper sulphate are antagonistic with diquat. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.

Ambush (permethrin) Gramoxone (paraquat)

Atradex (atrazine) Simatox (simazine)

Diurex (diuron)
11.Registered Crop(s) : Wheat, Oats, Lucerne, Pasture Renovation, Asparagus, Hops, Oilseed, Poppies, Orchards and Vineyards. Pre-harvest desiccation: Sunflowers, Linseed, Sorghum, Dry beans & peas, Lupins, Rapeseed, Soybeans, Pigeon Peas, Perennial legume seed crops and Potatoes.
12.Effect of Soil Texture on Herbicide : None.
13.Effect of Soil pH on Herbicide : None.
14.Effect of Soil Organic Matter on Herbicide : None.
15.Mode of Action : Contact, in dull conditions foliage translocated. Post-emergent.
16.Application Timing : Wheat - Between 4 leaf and early tillering. Oats - Between 3 leaf and early tillering. Pasture - Not greater than 4cm high.
17.Rate Variations : 300 mL - 5.0 L/ha.
18.Rates Selection : Lower rate when weeds are small and fresh. Higher rate when weeds are bigger or sward is dense.
19.Crop Damage (Crop Tolerance) : Refer growers label.
20.Effect on Crop : Desiccates crops that are sprayed.
21.Effect on Clover Species : Consult relevant pasture manipulation programs.
22.Soil Moisture at Application :
DRY - No problems.

MOIST - No problems.

WATERLOGGED - No problems.
23.Frost Effects : If foliage is frost damaged before application, expect reduced efficacy. If frost occurs during application, as plant cell activity decreases so does Reglone efficacy.
24.Frost Free Days Required After Application : Sufficient for plants to recommence active growth.
25.Effect of Application Water Quality on Herbicide :
Saline Water - None.

Soil Colloids - Free clay particles will effect efficacy. Reglone quickly adheres to clay.
26.Recommended Water Volume : 200 - 400 L/ha boom, 30 - 60 L/ha aircraft.
27.Nozzle Type : Flat fan.
28.Recommended Nozzle Pressure : 230 - 280 kPa (33.4 - 40.6 psi), avoid low pressure nozzles.
29.Recommended Filter Sizes : 50, 80 or 100 mesh.
30.Recommended Wetter : Agral 600 - 200ml/100L, BS 1000 - 120ml/100L
31.Other Additives : No.
32.Rain Fastness : 30 minutes.
33.Time Interval Before Effect is Noticed : Usually 2 - 3 days.
35.Effect of Herbicide/Disease Interaction on Crop : Unless severely affected not normally a problem.
36.Withholding Period : Minimum 1 day stock grazing or cutting for stock feed. Minimum 4 days prior to harvest of Rapeseed, Pigeon peas & Soybeans. 7 days potatoes.
37.Plant-Back Period : Cereals and broadacre crops less than 1 day.
38.Spray Tank Clean-Up : Thorough flushing with clean water.
39.Other Comments : Very rapidly and completely inactivated by soil, results from reaction between double positively charged diquat ions and clay minerals present in soils to form complexes. Diquat cannot be removed from such sites by washing. Most soils have sufficient capacity in the top 2 - 5 cm to bind many hundred times the normal field rates of diquat. Better results may be obtained when application is made in dull weather or at the end of the day. Gramoxone (paraquat) is preferred where grasses are dominant and Reglone where there are mainly broadleaved weeds.
