6 GENERAL DESCRIPTION:

Diclofop is a selective and translocated herbicide that is absorbed through both leaves and roots. Its main use is for controlling annual ryegrass and wild oats in wheat, barley and broadleaved crops and pastures. Toxicity to mammals and birds is low but it is toxic to fish. In land environments it presents few environmental hazards because of its low mobility in soil, low volatility, low toxicity and reasonably quick degradation in soil and water. Direct application to aquatic ecosystems should be avoided. Application to flood irrigated areas or similar may lead to contamination of water. Plants are likely to become resistant to diclofop after repeated applications.

7 APPLICATION METHODS AND TIPS:

Diclofop is normally applied in water with wetting agent as a post-emergence spray by boom sprays or aircraft. It is most effective when applied to actively growing plants. Plants under drought stress are very difficult to kill with diclofop. Ryegrass or wild oat plants in the two leaf stage are more susceptible to diclofop than older or younger plants. Successful control has been achieved on dewy and frost covered crops but it is recommended to avoid these conditions if possible.

11 COMPATIBILITY:

Hormonal herbicides such as 2,4-D are antagonistic. 2,4-D decreases the conversion from the ester to the active acid form, decreases translocation of diclofop, increases the rate of detoxification and competes at the fatty acid synthesis level. Plants treated with 2,4-D up to two weeks before or after diclofop application may be less susceptible to diclofop. MCPA antagonism is different and appears to be caused by reactions outside the plant.

Spraying oils and wetting agents improve the absorption of diclofop by plants. Spraying oils also improve the translocation of diclofop which improves weed control but may reduce the crops tolerance of diclofop.

14 HERBICIDE RESISTANCE:

Ryegrass and wild oats that are tolerant to diclofop occur naturally at low levels. After four or five annual applications of diclofop a significant level of diclofop tolerance would be expected if no other form of weed control was practiced.

20 MODE OF ACTION:

Diclofop is absorbed through the foliage and roots of nearly all plants. In susceptible plants it is converted from the ester to the biologically active acid form. Typically, less than 10 per cent of this is translocated in the phloem and xylem to accumulate in the growing tips. Cell division and elongation are stopped resulting in the stunted appearance of treated plants. Membranes are disrupted giving a 'water soaked' appearance. Fatty acid synthesis is stopped resulting in the death of growing tips, hence leaves of treated grasses can be easily pulled from their sheaths. Plants tolerant to diclofop appear to have a different fatty acid synthesis mechanism, degrade diclofop more quickly and do not convert as much of the inactive ester to the active acid form. It is normally, used as a post emergence herbicide but does have some pre emergence activity at high rates. Wild Oats and Annual Ryegrass germinating soon after spraying are often stunted.

23 PLANT SYMPTOMS:

Annual ryegrass and wild oats stop growing soon after application. The leaves take on a water soaked or oily appearance within a few days. About a week later, leaves become red-brown in colour and may be easily pulled from their sheaths before dying. Plants that recover have severely reduced root systems.

24 TOXICITY:

Mammalian toxicity - low.

Acute oral LD50 - 560 - 580 mg/kg (rat); > 1600 mg/kg (dog)

Acute dermal LD50 - > 5000 mg/kg (rat); 180 mg/kg (rabbit).

Skin - slightly irritating.

Eye

Birds - low, LD50 4400 mg/kg (quail).

Fish - toxic.

Invertebrates (eg. marron)

Bees - low toxicity.

27 ENVIRONMENTAL FATE:

Diclofop is strongly adsorbed on soils. Its solubility provides a slight risk for movement into ground water under extreme conditions. It is broken down in plants. In soil, microbes break down diclofop with a half life of around 28 days. At higher pH and under anaerobic conditions the half life is increased. Diclofop is rapidly excreted from animals and does not move into milk or eggs. It is not degraded by light.

11. Registered Crop(s) : Wheat, Barley, Triticale, Peas, Rapeseed, Cereal Rye, Linseed, Lupins, Safflower.

13. Effect of Soil Texture on Herbicide : No effect unless it affects plant growth.

14. Effect of Soil Organic Matter on Herbicide : No effect unless it affects plant growth.

15. Mode of Action : Foliar translocation, some contact and root absorption. Post-emergent.

16. Application Timing : 3 to 6 weeks after sowing, when cereals usually 2-5 leaves. Barley - Only when the crop is 4 - 5 leaf stage.

17. Rate Variation : 1.0 - 2.0 L/ha, do NOT exceed 1.5 L/ha on barley.

18. Rates Selection : Lower rate wild oats 2 - 3 leaf, Higher rate wild oats 3 - 4 leaf; see label.

20. Effect on Crop : Wheat - crop yellowing may occur in some seasons.

21a. Effect on Clover Species : Not affected.

22. Soil Moisture at Application :

DRY - If weeds are stressed expect lower efficacy.

MOIST - Should result in good control.

WATERLOGGED - If weeds are stressed expect lower efficacy. Barley may be less tolerant.

23. Frost Effects : Preceding application extended frost periods will reduce weed vigour and therefore weed control. During and after application okay but should be avoided.

24. Frost Free Days Required After Application : Nil

25. Effect of Application Water Quality on Herbicide :

Saline Water - no effect.

Soil Colloids - no effect.

27. Nozzle Type : Flat fan wide angle (11001 to 11003 or equivalent) for boom sprays.

28. Recommended Nozzle Pressure : 280 - 300 kPa (40.6 - 43.5 psi). Use small droplets (200 - 300 micron) and aim for a droplet density of approximately 25 - 50 droplets /cm2.

30. Recommended Wetter : Non ionic wetting agent.

31. Other Additives : Oils and adjuvants can be added to Hoegrass BUT when using oils damage risk is increased. Hoegrass + Turbo surfactant, temporary crop yellowing will occur due to removal of cuticle. Newly emerging leaves will not be affected.

32. Rain Fastness : Minimum 2 hours.

33. Time Interval Before Effect is Noticed : 7 - 10 days, depending on temperature.
