6 GENERAL DESCRIPTION:Chlorsulfuron was the first commercial herbicide from the sulfonylurea group. It is 100 times more active than traditional herbicides so very low rates are used in the field.
7 APPLICATION METHODS AND TIPS:Chlorsulfuron is usually mixed with 30-100 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 emergence applications and zero for pre emergence applications.
9 ADJUVANTS:Wetting agents: Not required for pre emergence applications. Wetting agents increase the weed kill on hard to wet weeds and only occasionally reduce the crop tolerance.
10 WATER QUALITY:Hard or salty water may reduce its effectiveness.
11 COMPATIBILITY:Non ionic surfactants and spraying oils increase the absorption. For spraying oils this may lead to crop damage and so they are not usually recommended.
12 EQUIPMENT:Boom sprays:
13 SPRAYER DECONTAMINATION:Clean up:
14 HERBICIDE RESISTANCE:Plant populations tolerant to chlorsulfuron are expected to occur naturally after repeated use.
15 REPLANTING INTERVALS:
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.
19 SOIL:Soil texture:
20 MODE OF ACTION:Uptake and translocation:
Physiological effects:Within the plant, chlorsulfuron stops cell division very quickly by its action on the ALS enzyme. Secondary effects on photosynthesis, respiration and ethylene production produce the symptoms of yellowing and reddening of grasses and leaf drop in broad-leaved weeds.
Residual Life and Breakdown:21 SELECTIVITY:
Crop tolerance:The tolerance of crops to chlorsulfuron is reduced in soils with high pH, sandy soils, soils with marginal zinc, manganese or copper levels, if leaching rains occur soon after spraying or if crops are waterlogged before or after spraying.
Varietal sensitivities:Wheat - Amery, Brookton, Calingiri and Kulin are sensitive to pre em applications and post em applications up to the 2 tiller stage. Increased stem breakage may occur in Kulin. Arrino is sensitive to pre em applications.
Effect on Clover Species:Effect on Medic Species:
SECONDARY EFFECTS:Chlorsulfuron does not affect the microbes associated with N fixation in legumes.
25 TOXICITY SYMPTOMS:Chlorsulfuron does not usually evoke any symptoms in animals.
26 FIRST AID: for Oral Intake:Induce vomiting preferably with Ipecac syrup.
27 ENVIRONMENTAL FATE:Chlorsulfuron has a half life in soil of about 2 weeks -2 months. Its half life is much longer in soils with high pH (up to 9 months). 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 high organic matter. Little is naturally degraded due to exposure to sunlight and volatilisation. Chlorsulfuron has an EPA classification for soil mobility that ranges from intermediate mobility to very mobile depending on the soil type. Mobility usually increases with increasing soil pH and decreasing organic matter. It will move up, down and sideways in the soil profile depending on the water flow. However, it is not expected to cause ground water contamination problems due to its relatively rapid degradation in plants and soils, low use rates and low toxicity.
Replanting Intervals:Some crops should not be planted for many months after chlorsulfuron application. This is because they are sensitive to extremely low levels of chlorsulfuron and not because of high levels of persistence of the herbicide in the soil. Lentils, Medic, sugar beet and onions are very sensitive to Chlorsulfuron. Canola, Setaria Millet, Lucerne, sunflower, potatoes, mustard corn and flax are sensitive. Peas, Beans, Mung Beans, Pearl Millet, Ryegrass, Sorghum, Cotton, Soybeans, Safflower, Bluegrass and Guar are moderately sensitive and Wheat, Triticale, Rye, Barley, Oats and Black Nightshade are tolerant.
Bio Accumulation:Chlorsulfuron does not accumulate in the milk or tissues of animals. Most is excreted intact in the urine of mono gastric animals or as a conjugate in ruminants.

29 REGISTERED WEEDS:See HerbiGuide Species Solution tab.
30 REGULATION AND LEGAL:UN number:
31 PROPERTIES:Water solubility at 25 C. - 60 ppm at pH 5; 7000 ppm at pH 7 and quoted up to 27,900 ppm under some conditions.
32 SPILLS:Sweep up granules and dispose in a chemical disposal pit.
33 FIRE:Extinguish with water spray, foam, carbon dioxide or dry agent.
