6 GENERAL DESCRIPTION:

A none selective, non residual, non volatile, broad spectrum, contact herbicide. Initially its major use was as a directed spray under bananas, grape vines and fruit trees. It is now registered for use in many crops as a pre-planting or directed spray.

7 APPLICATION METHODS AND TIPS:

Best results in warm weather on actively growing weeds.

Avoid spraying stressed, frost affected or diseased plants.

Ensure good coverage, especially on dense stands.

Avoid spraying green or young bark on desirable plants.

Use a minimum of 100 L/ha of water for application by boom spray.

Rainfast in 6 hours.

Do not apply when temperature is more than 33⁰C with a relative humidity of less than 50%.

Damage to transplants may occur from herbicide residue in fumigated soils or situations where microbial activity is very low.

It may remain active on inert surfaces such as plastic mulch and foliage contacting the surface may be damaged.

Check MRLs for export before using on crops destined for export.

8 WEATHER:

Rainfast in hours.

Soil moisture at application:

9 ADJUVANTS:

Wetting agents: A wetting agent is included in most formulations. Extra wetting agent is only likely to be required for high volume or low rate applications or on hard-to-wet weeds.

Spray oils:

10 WATER QUALITY:

Glufosinate-ammonium tolerates the normal range of water qualities found in field situations.

Hard water: Up to 200 ppm total soluble salts has little effect on activity. Di and tri valent ions such as calcium, magnesium, aluminium and iron seem to have the greatest effect. High levels iron appear to have the greatest effect.

Colloids: It is loosely bound to clay and organic matter in water but this is rarely a problem in the field unless very dirty water is used. Clearing of water with alum is not recommended as the alum is likely to have a greater negative effect than the clays.

pH in the range of 4-9 has little effect.

In rainwater, glufosinate-ammonium should have a long tank life.

11 COMPATIBILITY:

Trace elements.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 100 L/ha on young weeds. 500-1000 L/ha on large and dense stands of weeds. Coverage is more important than volume of application.

Nozzles: Flat fan.

Pressure: 150-400 kPa.

Hand sprays:

Hollow cone nozzles are recommended.

Controlled Droplet Application (CDA)

Apply with equipment with solid rather than bristle skirts.

Use carrier volumes of 20-30 L/ha when weeds are 10-15 cm tall and have skirt just touching the top of the weeds.

Avoid getting spray on green or uncallused trunks.

CDA application is not recommended in cherry orchards.

Aerial Application:

Not generally registered for aerial application because high water rates and good coverage are required.

13 SPRAYER DECONTAMINATION:

Clean Up:

Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through nozzles.

Decontamination:

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 twice with water.

14 HERBICIDE RESISTANCE:

There are no populations of weeds that have been reported as developing resistance to glufosinate-ammonium in Australia, however, tolerant plants are expected to occur and may dominate the weed population after repeated applications.

There are genes that have been used produce crops that tolerate glufosinate-ammonium.

Residues of glufosinate-ammonium have not been found in produce under normal use patterns.

17 RE-ENTRY PERIOD:

Wear protective clothing if in contact with the crop before the spray has dried.

18 PROTECTIVE CLOTHING:

Overalls, boots and washable hat. Use gloves and face shield when handling the concentrate.

19 SOIL:

It is not directly affected by soil type. Indirectly soil type may affect the level of stress of the plant which may affect control.

20 MODE OF ACTION:

Uptake and translocation:

It is absorbed by leaves through water channels in the waxy cuticle. 15-50% of the applied glufosinate-ammonium is absorbed in the first 2 hours and 20-80% in the first 8 hours. The speed and extent of absorption depends on plant species, stage of growth, temperature, humidity and the amount of herbicide applied.

Translocation is very limited with some movement around the leaf or between leaves or in passive water movement around the plant. 0.3-2.3% of the applied glufosinate-ammonium is typically translocated to the roots. In some perennial plants (e.g. Blady Grass) this may be enough to reduce rhizome regrowth but generally the amount translocated is insufficient for control of weeds. Likewise, damage to plants that only have a small portion of their foliage sprayed is generally limited to the sprayed foliage. It is classed as a contact herbicide and good coverage is usually required for good control.

Physiological effects:

In plants nitrate is absorbed from the soil and forms ammonium which combines with glutamate to form the amino acid glutamine in the presence of the enzyme glutamine synthetase. Glufosinate-ammonium disrupts the action of glutamine synthetase. This results in a build up of ammonia in the plant and reduced glutamine production which subsequently stops photosynthesis. The plant dies from a combination of ammonia toxicity and a lack of carbohydrate from photosynthesis. Ammonium levels start to increase soon after application. Photosynthesis starts to decrease about 2 hours after application and has usually stopped by 8 hours after application.

Residual Life and Breakdown:

Essential non residual and breaks down quickly with a soil half life of 1-3 weeks. See 27 Environmental fate for breakdown process.

History:

A new amino acid, phosphinothricin, was discovered in bacteria (Streptomyces viridochromogenes) in 1971 and its herbicidal activity discovered by Hoechst Ag in 1976. A synthetic form was produced and bound to ammonium to form the active ingredient. It was launched in Australia in 1990.

22 DISEASE AND INSECT EFFECTS:

23 PLANT SYMPTOMS:

Plant growth stops a soon after application. In warm conditions a general yellowing can be seen within a day or two then dead patches on the foliage or leaf tips start to appear as the plant wilts and dies in 1-3 weeks. In cool conditions these symptoms may take twice as long to appear. The symptoms are generally slower to appear than those of the bipyridyl herbicides (paraquat, diquat and Spray.Seed) and faster than glyphosate (Roundup). It usually only affects green vegetation contacted by the spray.

27 ENVIRONMENTAL FATE:

It has a half life in soil of 1-3 weeks. It is broken down mainly by micro-organisms. The major metabolite produced during breakdown of glufosinate-ammonium is MPPA (methyl-phosphinicopropionic acid) and this has a half life of about 30 days. The final breakdown products are CO² and other products that are bound by the soil or within micro-organisms.

Half life in water: 20-300 days depending on biological activity. pH has little effect. Little hydrolysis.

It has an EPA classification for soil mobility that ranges from

Glufosinate-ammonium and its degradation products are loosely adsorbed by clay.

Ground water contamination is unlikely despite the solubility of glufosinate-ammonium and some of its breakdown products because they a degraded relatively quickly. Field studies show that that residues are only fond in the top 20 cm of the soil profile.

Glufosinate-ammonium is stable in clean water with a half life of more than 300 days. In biologically active water the half life is around 20 days.
