<br />potential for spiny drift. The applicator and [he entity authorizing spraying are
<br />responsible for considering all these factors when making decisions.
<br />Spray drift from applying this product may result in damage [o sensitive plants
<br />adjacent to the treatment area. Only apply this product when the potential for
<br />drift to these and other adjacent sensitive areas (e.g, residrn[ial areas, bodies of
<br />water, known habitat for threatened or endangered species, or non-target crops)
<br />is minimal. Do not apply when the following conditions exist that increase
<br />the likelihood of spray drift from intended targets: high or gusty winds, high
<br />temperamres, low humidity, tempemmre inversions.
<br />To minimize spray drift, [he applicator should be familiar with and take into
<br />account the following drift reduction advisory information. Additional information
<br />may be available from state enforcement agencies or the Cooperative Extension
<br />on the application of this product.
<br />The best drift management strategy and mast effective way to reduce drift potential
<br />are [o apply large droplets that provide sufficient coverage and control. Applying
<br />larger droplets reduces drift potential, but will not prevent drift if applications
<br />are made improperly, or under unfavorable environmental conditions (see WIND,
<br />TEMPERATURE AND HUhIID]TY, and TEMPERATURE INVERSIONS).
<br />CONTROLLING DROPLET SIZE
<br />• Volume-Use high flow rote nozzlesto apply [he highestpractical spiny volume.
<br />Nozzles with higher rated flows produce larger droplets.
<br />• Pressure-Do not exceed the nozzle manufacturer's recommended pressures.
<br />For many nozzle types, lower pressure produces larger droplets. When higher
<br />flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
<br />• Number ofNozzles-Use the minimum number of nozzles that provide uniform
<br />coverage.
<br />• Nozzle Orientation-Orienting noules so that the spray is released parallel to
<br />the airstream produces larger droplets than other orientations and is recom-
<br />mendedpractice. Significant deflection from [he horizontal will reduce droplet
<br />size and increase drift potential.
<br />• Nozzle Type-Use a nozzle type that is designed for [he intended application.
<br />With most nozzle types, narrower spiny angles produce larger droplets. Consider
<br />using low-drift nozzles. Solid stream nozzles oriented straight back produce
<br />the largest droplets and [he lowest drift. Do not use nozzles producing a mist
<br />droplet spray.
<br />APPLICATION HEIGHT
<br />Making applications at the lowest possible height (helicopter, ground driven spiny
<br />boom) [hat is safe and practical reduces exposure of droplets ro evaporation and
<br />wind.
<br />SWATH ADJUSTMENT
<br />When applications are made with a crosswind, the swath will be displaced down-
<br />wind. Therefore, on the up and downwind edges of the treatment area, the
<br />applicator must compensate for [his displacement by adjusting the path of the
<br />application equipment (e.g. aircmft, ground) upwind. Swath adjustment distance
<br />should increase witfi inereasing drift poential (higher wind, smaller droplets, etc.).
<br />WIND
<br />Drift potential is lowest between wind speeds of 3-I O mph. However, many
<br />factors, including droplet size and equipment type, determine drift potential aI any
<br />given speed. Application should be avoided below 3 mph due to variable wind
<br />direction and high inversion potential. NOTE: Local terrain can influence wind
<br />patterns. Every applicator should be familiar with local wind patterns and how
<br />they affect spiny drift.
<br />TEMPERATURE AND HUMIDITY
<br />When making applications in low relative humidity, se[ up equipment [o produce
<br />larger droplets to compensate for evapomtion. Droplet evapomtion is most severe
<br />when conditions are both hot and dry.
<br />TEMPERATURE INVERSIONS
<br />Drift potential is high during a tempemmre inversion. Temperature inversions
<br />restrict vertical air mixing, which causes small suspended droplets to remain
<br />in a concentrated cloud, which can move in unpredictable directions due to
<br />the light variable winds common during inversions. Temperature inversions are
<br />chazacrerized by increasing temperamres with altitude and are common on nights
<br />with limited cloud cover and light to no wind. They begin to forn as the sun
<br />sets and often continue into the rooming. Their presence can be indicated by
<br />ground fog; however, if fog is not present, inversions can also be identified by
<br />the movement of smoke from a ground source or an aircmft smoke generator.
<br />Smoke that layers and moves laterally in a concentrated cloud (under low wind
<br />conditions) indicates an inversion, while smoke that moves upward and rapidly
<br />dissipates indicates good vertical air mixing.
<br />WIND EROSION
<br />Avoid treating powdery dry or light sandy soils when conditions are favorable for
<br />wind erosion. Under these conditions, the soil surface should first be settled by ~'
<br />rainfall or irrigation.
<br />SENSITIVE AREAS
<br />The pesticide should only be applied when the potential for drift [o adjacent
<br />sensitive areas (e.g. residential areas, bodies ofwater, known habitat for threatened
<br />or endangered species, ornon-target crops) is minimal (e.g. when wind is blowing
<br />away from the sensitive areas).

<br />HIGH-VOLUME SPRAY EQUIPMENT
<br />ARSENAL maybe applied using high-volume spray equipment For best results,
<br />apply ARSENAL using [he leas[ amount of water practical to obtain uniform
<br />coverage of the vegetation foliage. Using excessive spiny volumes which cause
<br />mnofffrom [he plant foliage may result in reduced performance.
<br />When using spiny volumes greater than 60 gallons per acre, additional nonionic
<br />surfactant must be added at [he rate of I quart per 100 gallons of spray solution
<br />to provide optimum wetting and/or contact activity. A foam reducing agent may
<br />be added at the recommended Zabel rote, if needed. If desired, a spray panem~
<br />indicator may be added al the recommended label rate.
<br />To mix the spiny solution, determine the proper ARSENAL pints per acre rate
<br />from the WEEDS CONTROLLED section of this label.
<br />IMPORTANT: DO NOT exceed recommended dosage rote per acre. DO NOT
<br />side-trim desirable vegetation with This product. Clean application equipment after

<br />WEEDS CONTROLLED
<br />ARSENAL will provide postemergence con Vol with residual control of [he follow-
<br />ing target vegetation species at the rotes listed. Residual convol refers to control
<br />of newly germinating seedlings in both annuals and perennials. In general, an-
<br />nual weeds may be controlled by preemergence or postemergence applications
<br />of ARSENAL; whereas, for established biennials and perennials, postemergence
<br />applications of ARSENAL are recommended. ARSENAL should be used only
<br />in accordance with the recommendations on this label and the leaflet label.
