STRADA is a systemic herbicide formulated as a water dispersible granule suitable for selective postemergence weed control. When applied according to label directions, it is effective in the control of several annual and perennial broadleaf weeds and sedges.
To achieve the best control, apply STRADA to young, actively growing weeds. This stage usually corresponds to a rice growth stage between 2 and 4 leaves. Mix STRADA with water, and apply at specified rates as a foliar spray by ground or air application to water-seeded or dry-seeded rice. Efficacy may depend on the following parameters:
• Weed size at application
• Growing and environmental conditions (e.g. soil moisture, relative humidity, and temperature) prior to and following treatment
• Soil pH, texture, and organic matter content
• Water management
STRADA contains the active ingredient, orthosulfamuron, a sulfonylurea herbicide which inhibits the plant enzyme acetolactate synthase (ALS) which is also known as acetohydroxy acid synthase (AHAS). Inhibition of this enzyme blocks branched-chain amino acid biosynthesis of valine, leucine, and isoleucine which leads to plant death. STRADA is particularly efficient by foliar application. Once in the target weed, it is translocated by xylem and phloem. Soon after STRADA is applied, growth of susceptible weeds is inhibited, and the plants are no longer competitive with rice. Typically, weed leaves turn yellow, then reddish; and within 10 to 20 days, depending on weed size, species, and growing conditions, the stem and roots die. Treated target weeds may stay green but are stunted and not competitive with the crop.

• Do not apply after 1/2 inch internode elongation.
• Do not enter treated fields until 12 hours after application (REI = 12 hours).
• Use of an approved agricultural surfactant or adjuvant is necessary for STRADA.
• Do not apply where runoff or irrigation water may flow directly onto agricultural land other than rice fields.
• Do not apply STRADA directly or indirectly to crops other than rice.
• Do not make more than 1 application or apply more than 2.1 ounces of STRADA per acre (equivalent to 0.067 lb ai/a) during the growing season in both the first and ratoon crops combined.
• Do not allow tank mixtures containing STRADA to sit overnight.
• Do not apply this product through any type of irrigation system.
• Refer to the Spray Drift Management and Endangered Species sections of the label for buffer restrictions.

• Rainfast within 6 hours.
• Application of STRADA to fields which have been levelled (except water levelling) within 12 months prior to application may result in rice injury in areas that   have been cut or filled.
• Poor weed control may result from application of STRADA made to plants under stress from abnormally hot or cold weather; environmental conditions such as drought, hail damage, hydrogen sulphide; or prior herbicide applications.
