3 ACTIVE INGREDIENTS: Rimsulfuron 250 g/kg as a dry flowable water dispersible granule4 CHEMICAL GROUP: B.
5 RELATED HERBICIDES:
Chlorsulfuron, metsulfuron, triasulfuron.
6 GENERAL DESCRIPTION:Mainly used for the suppression of Blackberry Nightshade and control of other broadleaf weeds in Tomatoes.
7 APPLICATION METHODS AND TIPS:9 ADJUVANTS:
Spray oils may improve weed control but may reduce selectivity on the crop.
10 WATER QUALITY:Hard water
11 COMPATIBILITY:Trace elements.
12 EQUIPMENT:Boom spray as overall treatment of band spray.
14 HERBICIDE RESISTANCE:Weeds tolerant to rimsulfuron are expected to develop after multiple applications of this and other group B herbicides.
18 PROTECTIVE CLOTHING:20 MODE OF ACTION:
Selective and systemic.
Uptake and translocation:Absorbed by foliage and roots.
Physiological effects:Inhibits the acetolactate synthase (ALS) enzyme.
Cell growth and division is stopped because branched chain amino acid synthesis is stopped.
Residual Life and Breakdown:Selectivity:
Selectivity is due to rapid inactivation of rimsulfuron by tolerant species.
23 PLANT SYMPTOMS:May cause temporary chlorosis or a lighter green colour of the crop (tomatoes) which usually disappears within 2 weeks days. Chlorosis usually doesn't occur if there has been 3 sunny days before spraying.
Weeds may take 1-3 weeks to yellow or discolour before dying.
SECONDARY EFFECTS:24 TOXICITY:
Low toxicity to humans, animals, invertebrates, insects and fish.
Over 50% is excreted intact in the faeces and urine in mammals.
No detectable residues were found in the fat, milk or muscle of lactating goats.
At high dose rates, residues of <0.02 ppm were found in fat, eggs and muscle of poultry.
Details:Mammalian toxicity - Low toxicity.
Acute oral LD50 - Low toxicity. >5000 mg/kg (rats), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - Low toxicity. > 2000 mg/kg (rabbit).
Skin - Not irritating
Eye - Moderate irritant
Inhalation - LC50 - > 5400 mg/m-3 air (rat). - Low toxicity.
Chronic oral toxicity NOEL - 1.6 mg/kg/day for one year.
Acceptable daily intake ADI for humans - 0.02 mg/kg/day.
Not carcinogenic, mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).
Other Species - Birds - Low toxicity.
Fish - Low toxicity LC50 > ppm.
Invertebrates - Low toxicity.
Bees - Low toxicity.
Moderately toxic to green algae.
Highly toxic to Duckweed (Lemna spp.).
25 TOXICITY SYMPTOMS:Symptoms are mainly decreased body weight gain, loss of appetite and diuretic effect at high dose rates (>190 mg/kg/day).
26 FIRST AID:27 ENVIRONMENTAL FATE:
It has a half life in soil of 5-17 days in the field. In experiments it has ranged from 5 days at 60% soil moisture and 20C to 77 days at 40% soil moisture and 5C. The half life is around 18-24 days under anaerobic conditions.
Sunlight appears to have little effect on the rate of breakdown.
The half life in water at 25C is 5-15 hours at pH 9, 7-25 days at pH 7 and 1.5-5 days at pH 5.
It has an EPA classification for soil mobility that ranges from
It is highly mobile in the soil but field studies indicate little downward movement in the soil.
Leaching - <0.001 ppb soil water concentration is expected at a depth of 1 m in soil. In field studies none was found below 15 cm deep.
It is not expected to accumulate in the soil or ground water.
Ground water contamination - not expected.
Replanting intervals - Only tomatoes and potatoes can be grown after a tomato crop that has been treated. 18 months for all other Wheat, Barley and Oats and 23 months for Sunflower, Maize and Zucchini in Australia until further data presented. In the USA Replanting interval for Wheat, Oats and Barley is 6 months and 11 months for Sunflower, Maize and Zucchini.
Accumulation in milk and tissues. - none expected.
No residues were found in tomato 7 days post treatment. Metabolites were <0.1ppm 60 days after treatment.
Rimsulfuron and it metabolites appear to be not soluble in fat.
Maximum Residue Limit (MRL) - 0.05 mg/kg.

Flush through lines then agitate for 15 minutes before emptying. Repeat this then flush with clean water. Remove and clean filters and nozzles separately. Don't use chlorine with ammonia cleaners or fertilisers because this can release toxic chlorine fumes.
Remove the nozzles and screens and clean separately.
