6 GENERAL DESCRIPTION:

2,4-D ester is foliar absorbed, post emergent, translocated herbicide for the control of broad leaved weeds. There is virtually no absorption through the roots. It has a useful level of volatility for penetrating stubbles and other protected areas. This also makes it safer than amine formulations for application before planting crops. The volatility precludes its use in close proximity to sensitive species. Low levels of drift or vapours can cause high levels of symptoms on sensitive species.

7 APPLICATION METHODS AND TIPS:

Best results when applied in fine weather to actively growing plants.

8 WEATHER:

Rainfast in 3-6 hours

Frost effects : Frost before application may retard weed growth thus reducing translocation. For best results, 2-3 frost free days required after application.

Wind : Regulations require application when wind speeds are between 3 and 15 km/hour to reduce the risk of damage caused by drift. Avoid spraying when wind is blowing towards sensitive crops.

Inversions: Don't apply during inversion conditions as damaging levels of herbicide drift may move a kilometre or more.

Temperature :

Delta T and Relative Humidity : Avoid application when Delta T is greater than

9 ADJUVANTS:

Generally none are required.

Wetting agents may be useful for hard to wet plants and in non selective situations to improve droplet retention.

Wetting agents and spray oils may increase the risk of crop damage.

10 WATER QUALITY:

Hard water: Generally quite tolerant to hard water. Do a jar test to see if the emulsifiers become overloaded and the herbicide separates from the water.

Salty water: Often separates in salty water. Do a jar test to see if the emulsifiers become overloaded and the herbicide separates from the water.

Colloids: Tolerates muddy water.

pH: Tolerates the range of pH normally found in the field.

11 COMPATIBILITY:

Trace elements.

Not compatible with zinc heptahydrate.

Ester formulations generally have good compatibility providing the emulsifier is not overloaded and the product separates from the water (do a jar test).

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays, high and low volume hand leads. It is generally not recommended for use in aircraft or misters because of concerns with drift.

Regulations require the use of coarse droplets to reduce the impacts of drift.

Recommended water volume: 30 - 120 L/ha for boom sprays, 10 - 90 L/ha aircraft and 200 - 1000 L/ha for hand leads.

80 or 110 degree flat fan nozzles operating at 150-300 kPa is a typical set up for boom sprays. Larger orifice nozzles (eg 02 or 03) or air induction nozzles are used to reduce drift but water volumes need to be about 80 L/ha or more for good coverage of small weeds.

13 SPRAYER DECONTAMINATION:

Clean Up:

Remove filters and nozzles and manually clean separately. Rinse with kerosene or water plus degreaser. Rinse with 1% ammonia through boom then triple rinse with soapy water or water plus wetting agent and run through boom.

Decontamination:

Remove filters and nozzles and clean separately. Rinse with kerosene or water plus degreaser. Wash out with hot soapy water or water plus 0.25% wetting agent. Fill with 1% solution of ammonia and leave for several hours. Triple rinse with water plus wetting agent. Or use a commercial spray tank and equipment cleaner. Check and clean filters and nozzles again if necessary.

It may not be possible to decontaminate old spray tanks and hoses.

14 HERBICIDE RESISTANCE:

Some plants have developed some resistance to 2,4-D.

These plant backs are generally quite conservative and problems are rarely seen with shorter periods because most of the free 2,4-D ester evaporates within a day or two of spraying.
