6 GENERAL DESCRIPTION:It is a relatively non selective and translocated herbicide that is absorbed through the leaves and roots. Its main uses are for the control of a large variety of grass and broad-leaved weeds in industrial situations. It is of low toxicity to mammals, birds and fish. Sulfometuron acts on the ALS enzyme in plants which is not present in animals and this is the main reason for its low toxicity. Its main environmental hazard is transport in water over recently treated areas. Plants resistant to sulfometuron have developed and are expected after repeated use.
7 APPLICATION METHODS AND TIPS:Sulfometuron is usually mixed with 30-200 L water per hectare and broadcast through hydraulic nozzles. It can be applied in ultra low volumes of carrier.
8 WEATHER:Rainfast in 4 hours for post emergent applications.
9 ADJUVANTS:Adjuvants are not necessary for pre emergence applications.
10 WATER QUALITY:Hard water: Avoid hard water.
11 COMPATIBILITY:Sulfometuron forms stable metal and ammonium salts so it is incompatible with most trace elements and ammonium sulphate.
12 EQUIPMENT:Apply by boom spray or aircraft. Water volumes greater than 30 L/ha are usually adequate. Use medium to coarse sprays if drift needs to be minimised.
13 SPRAYER DECONTAMINATION:Clean up:
14 HERBICIDE RESISTANCE:Plant populations tolerant to sulfometuron are expected to occur naturally after repeated use.
15 REPLANTING INTERVALS:
|Most broadacre crops||12 months or more depending on rate.|
|Eucalypts||1 day at low rates.|
16 WITHHOLDING PERIODS:
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:Longer residual on high pH alkaline soils.
20 MODE OF ACTION:Most of the sulfometuron applied to leaves is absorbed. Most is translocated in the phloem. Absorption by roots from the soil solution is not as efficient but this is compensated for by better movement up to the leaves. Within the plant, sulfometuron stops cell division very quickly by its action on the ALS enzyme. Degradation products are non toxic and herbicidally inactive. Secondary effects on photosynthesis, respiration and ethylene production produce the symptoms of yellowing and reddening of grasses and leaf drop in broad-leaved weeds.
21 SELECTIVITY:Crop tolerance:
Varietal sensitivities:Effect on Clover Species:
Effect on Medic Species:Kills medics.
Effect on Lucerne:Kills young lucerne and severely damages established lucerne.
Effect on Native Plants:Eucalypts are reasonably tolerant. Low levels from drift are not expected to cause significant problems. Water flowing from treated areas can cause significant damage.
22 DISEASE AND INSECT EFFECTS:23 PLANT SYMPTOMS:
SECONDARY EFFECTS:24 TOXICITY:
Details:Poison schedule: S5.
Other Species:Birds: low toxicity. Acute dietary LC50 >5000 ppm for mallard ducks and bobwhite quail for sulfometuron methyl. 8 day dietary LC50 >5000 ppm.
25 TOXICITY SYMPTOMS:Single doses of sulfometuron do not usually evoke any symptoms in animals.
26 FIRST AID:If SWALLOWED: No intervention is necessary. Do NOT give anything by mouth to a semiconscious or unconscious patient.
27 ENVIRONMENTAL FATE:Half life in soil: Sulfometuron has a half life in soil of about 12 months. Its half life is much longer in soils with high pH. At a soil pH of less than 7 it is broken down by hydrolysis and microbial degradation. At a pH of more than 8 there is little hydrolysis and only microbial breakdown. Breakdown is most rapid in warm, moist, acid and light textured soils with a high organic level.
