3 ACTIVE INGREDIENTS: Butafenacil 200g/kg plus Triasulfuron 500g/kg.Formulation:
4 CHEMICAL GROUP: G, B.Inhibitor of protoporphyrinogen oxidase and acetolactate synthase inhibitor.
5 RELATED HERBICIDES:Chlorsulfuron (Glean), metsulfuron (Ally), oxyfluorfen (Goal), sulfometuron (Oust), triasulfuron (Logran).
6 GENERAL DESCRIPTION:An agricultural herbicide for knockdown and residual control of a broad spectrum of grass and broad leaf weeds. It is normally applied before planting.
7 APPLICATION METHODS AND TIPS:Apply in fine weather at least one day before planting.
11 COMPATIBILITY:Non ionic surfactants and spraying oils increase the absorption and herbicidal activity.
14 HERBICIDE RESISTANCE:Plant populations tolerant to triasulfuron are expected to occur naturally after repeated use. Tolerant crops can be developed.
20 MODE OF ACTION:Most of the triasulfuron applied to leaves is absorbed. Small amounts move out of the leaf to other shoots and even less to the roots. 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, triasulfuron 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.
21 SELECTIVITY:Crop tolerance:
Effect on Clover Species:Effect on Medic Species:
SECONDARY EFFECTS:Triasulfuron does not affect the microbes associated with N fixation in legumes.
22 DISEASE AND INSECT EFFECTS:24 TOXICITY:
25 TOXICITY SYMPTOMS:Triasulfuron does not usually evoke any symptoms in animals.
27 ENVIRONMENTAL FATE:Triasulfuron 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. Triasulfuron 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 triasulfuron application. This is because they are sensitive to extremely low levels of triasulfuron and not because of high levels of persistence of the herbicide in the soil. Lentils, Medic, sugar beet and onions are very sensitive to triasulfuron. 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.
31 PROPERTIES:Vapour Pressure at 25 C. - Triasulfuron Very low.

|36.||Withholding Period : 49 days.|
|37.||Plant-Back Period : Wheat - 1 day. Durum Wheat - is one day but longer times are preferred as some varieties are sensitive. Barley, Oats, Triticale, and Cereal Rye - following season. For other crops could be up to 24 months depending on soil pH.|
|38.||Spray Tank Clean-Up : Residues of triasulfuron may cause damage to crops other than wheat if these crops are sprayed with contaminated equipment.|
|39.||Other Comments : Apply before sowing to a moist seed bed without clods or ridges. Incorporation by sowing improves the reliability of the weed control results, use narrow low profile 10 cm combine points to ensure even mixing of soil. Poor incorporation will result in uneven weed control or 'striping' of weeds. High temperature and moisture increase the rate of degradation. Rainfall following application, preferably within 7 - 10 days, is needed to 'activate' Logran and move it into the weed root zone.|
