PRODUCT INFORMATION
TRAVALLAS Herbicide is used for selective postemergence control or suppression of broadleaf weeds in wheat (winter, spring and durum), and barley not underseeded with legumes or grasses. TRAVALLAS contains three active ingredients formulated as oil dispersion. TRAVALLAS is to be mixed with water and applied as a uniform broadcast spray early postemergence to the crop, to the main flush of actively growing broadleaf weeds.

Biological Activity and Environmental Conditions
Warm, moist growing conditions promote active weed growth and enhance the activity of TRAVALLAS by allowing maximum foliar uptake and contact activity. Weeds hardened off by cold weather or drought stress may not be adequately controlled or suppressed and regrowth may occur. TRAVALLAS may injure crops that are stressed from adverse environmental conditions (such as extreme temperatures or moisture), abnormal soil conditions, or cultural practices. For best results, ensure thorough spray coverage of target weeds. See remaining "DIRECTIONS FOR USE" sections of this label for complete use details.
Degree of control and duration of effect are dependent on weed sensitivity, weed size, crop competition, growing conditions at and following treatment, and spray coverage. TRAVALLAS is rain-fast 1 hour after application.

IMPORTANT RESTRICTIONS
• Injury to or loss of desirable trees, adjacent sensitive crops, or vegetation may result from failure to observe the following:
- Do not apply, drain or flush equipment on or near desirable trees or other plants or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots.
- Do not discharge excess material on the soil at a single spot in the field, grove, or mixing/loading station.
- Do not store pesticides near well sites.
• Do not apply TRAVALLAS to wheat or barley that is stressed by severe weather conditions, drought, low fertility, water-saturated soil, disease, or insect damage, as crop injury may result. Risk of injury is greatest when crop is in the 2 to 5- leaf stage. Severe winter stress, drought, disease, or insect damage following application also may result in crop injury.
• Do not apply to irrigated land where tailwater will be used to irrigate crops other than wheat and barley.
• Do not apply by air in the State of New York.
• Do not use in Alamosa, Conejos, Costilla, Rio Grande, and Saguache counties of Colorado.
• Do not apply TRAVALLAS within 60 days of crop emergence where an organophosphate insecticide has been applied as an in-furrow treatment because crop injury may result.
• Do not use TRAVALLAS plus Malathion because crop injury may result.
• Do not apply to crops underseeded to legumes or grasses as injury to forage may result

IMPORTANT PRECAUTIONS
• Varieties of wheat (including durum) and barley may differ in their response to various herbicides. Consult your state experiment station, university, or extension agent as to crop sensitivity to any herbicide. If no information is available, limit the initial use to a small area.
• Application of TRAVALLAS to crops that are stressed by severe weather conditions, drought (including low levels of subsoil moisture), near freezing temperatures prior to, at, and following time of application, low fertility, water-saturated soil, disease, or insect damage, may result in crop injury and reduced weed control may occur.
• Under certain conditions such as heavy rainfall, prolonged cold weather, or wide fluctuations in day/night temperatures prior to or soon after TRAVALLAS application, temporary discoloration and/or crop injury may occur. To reduce the potential of crop injury, tank mix TRAVALLAS with 2,4-D (ester formulations perform best - see the "TANK MIXTURES" section of this label) and apply after the crop is in the tillering stage of growth.
• Effects of Temperature on Herbicidal Activity: Herbicidal activity of TRAVALLAS is influenced by weather conditions. Optimum activity requires active plant growth. The temperature range for optimum herbicidal activity is 55°F to 75°F. Reduced activity will occur when temperatures are below 45°F or above 85°F. Frost before application (3 days) or shortly after (3 days) may reduce weed control and crop tolerance.
• Calibrate sprayers only with clean water away from the well site. Make scheduled checks of spray equipment. Ensure that all operation employees accurately measure pesticides. Mix only enough product for the job at hand, and avoid overfilling of spray tank.
• When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix.

WEED RESISTANCE
TRAVALLAS contains the active ingredients thifensulfuron-methyl, metsulfuron-methyl, and fluroxypyr meptyl and is a Group 2 and Group 4 herbicide based on the mode of action classification system of the Weed Science Society of America. When herbicides with mode of action classifications that affect the same biological sites of action are used repeatedly over several years to control the same weed species in the same treatment area, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that area. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different biological site of action. To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide
applications that affect a different site of action. Weed escapes that are allowed to go to seed, and movement of plant material between treatment areas on equipment will promote the spread of resistant biotypes. It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative to determine appropriate actions for treating specific resistant weed biotypes in your area.
