6 GENERAL DESCRIPTION:

2,4-D amine is a post emergent, translocated herbicide for the control of broad leaved weeds. It is mainly absorbed through the foliage with some root uptake. Its low level of volatility makes it safer to use than the ester formulations close to sensitive crops. Low levels of drift 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 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: There may be a slight loss of activity due to ionic bonding in very hard water.

Salty water: Relatively tolerant of salty water.

Colloids: Some 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.

Do NOT mix with :- Trace element fertilisers, glyphosate 360 and CT

Zinc sulphate and copper sulphate are antagonistic with 2,4-D amine. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays, aircraft, high and low volume hand leads, misters.

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.

Nozzle type: Flat fan at pressures of 200 - 300 kPa (28.6 - 43.5 psi).

13 SPRAYER DECONTAMINATION:

Clean Up:

Remove filters and nozzles and manually clean separately. Rinse with soapy water or water plus wetting agent and run through boom. Rinse with water.

Decontamination:

Remove filters and nozzles and manually clean then soak in 500 mL household ammonia in 10 L water for 30 minutes.

Rinse sprayer with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Fill with 1% solution of ammonia and leave for several hours. Triple rinse with water. Or use a commercial spray tank and equipment cleaner.

Rinse nozzles and filters in water and replace.

14 HERBICIDE RESISTANCE:

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