6 GENERAL DESCRIPTION:
Metosulam is a foliar absorbed, selective and translocated herbicide for controlling broad leaf weeds in cereal and some grain legume crops.7 APPLICATION METHODS AND TIPS:
Metosulam is usually mixed with 30-100 L water per hectare and broadcast through hydraulic nozzles.8 WEATHER:
Rainfast in 2 hours.9 ADJUVANTS:
Various depending on situation. Don't use adjuvants when spraying Lupins.10 WATER QUALITY:
Hard water:11 COMPATIBILITY:
Trace elements.12 EQUIPMENT:
Boom sprays:Aerial application:
Not recommended for aerial application.13 SPRAYER DECONTAMINATION:
Clean Up:14 HERBICIDE RESISTANCE:
Broadleaf plant populations tolerant to metosulam are expected to occur after repeated use.15 REPLANTING INTERVALS:
Crop | Time |
Barley | 0 days |
Beans | 9 months |
Brassica crops | 9 months |
Canola | 9 months |
Cereal Rye | 0 days |
Clover | 9 months |
Lucerne | 9 months |
Lupins | 9 months |
Medics | 9 months |
Oats | 0 days |
Peas | 9 months |
Triticale | 0 days |
Wheat | 0 days |
16 WITHHOLDING PERIODS:
Crop | Type | Time |
Cereals | Harvest | Not required |
Cereals | Grazing | 14 days |
Lupins | Harvest | Not required |
Lupins | Grazing | 28 days |
17 RE-ENTRY PERIOD:
18 PROTECTIVE CLOTHING:19 SOIL:
Soil texture: little effect.20 MODE OF ACTION:
Inhibits the ALS (acetolactate synthase) enzyme.Uptake and translocation:
Most of the metosulam applied to leaves is absorbed.Physiological effects:
Within the plant, metosulam 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, reddening and leaf drop.Residual Life and Breakdown:
21 SELECTIVITY:Crop tolerance:
Temporary yellowing and height reduction may occur.Varietal sensitivities:
Wheat - Cadoux, Datatine, Goldmark, H45 and Silverstar appear sensitive.Effect on Clover Species:
Damages clover.Effect on Medic Species:
Damages medics.Effect on Lucerne:
Damages lucerne.Effect on Native Plants:
Many native plants that are not in the Brassicaceae family will tolerate metosulam.22 DISEASE AND INSECT EFFECTS:
Brown leaf spot and insect damage may make lupins more susceptible to damage.23 PLANT SYMPTOMS:
Growth stops soon after application. About a week later plants will start to yellow or redden. In broad-leaved weeds this may be an intervenal yellowing. Annual weeds are usually dead within 4 weeks of spraying. Under cold and wet conditions they may remain alive as severely stunted plants.SECONDARY EFFECTS:
Metosulam does not affect the microbes associated with N fixation in legumes.24 TOXICITY:
Summary:Details:
Poison schedule: S6.Other Species:
Birds: low toxicity. LD50 Bobwhite quail >2250 mg/kg. Mallard duck >2000 mg/kg.25 TOXICITY SYMPTOMS:
Metosulam does not usually evoke any symptoms in animals under normal exposures.26 FIRST AID:
If SWALLOWED: Wash out mouth with water. Do NOT induce vomiting. Give a glass of water. Do NOT give anything by mouth to a semiconscious or unconscious patient.27 ENVIRONMENTAL FATE:
Metosulam has a half life in soil of 6-47 days. It is degraded by microbial action. The half life is lowest when microbial activity is highest.28 REGISTERED CROPS:
See HerbiGuide Species Solution tab.29 REGISTERED WEEDS:
See HerbiGuide Species Solution tab.30 REGULATION AND LEGAL:
UN number: UN 3082.31 PROPERTIES:
Colour: Cream/brown granules or white to beige liquid.32 SPILLS:
Absorb spill with earth, sand, clay or absorbent material such as vermiculite.33 FIRE:
Extinguish with water spray, foam, carbon dioxide or dry agent.34 COMMENTS:
Poorer results noted when sprayed under overcast conditions and 40 points of rain on the following day compared to that sprayed 1 day before in fine sunny weather at Hyden 1995.35 REFERENCES:
