SPECID4EN LABEL UPDATES AVAILABLE AT W\i'\i~.CREENBOOK.NET 2 potential for spiny drift. The applicator and the entity authorizing spraying are responsible for considering all these factors when making decisions. Spiny drift from applying this product may result in damage to sensitive plants -adjacent [o the Ircatmrnt area. Only apply this product when the potential for drift m these and other adjacent sensrdvt areas.(c.g. residential areas, bodies of wateq known habitat for threatened or endangered species, or non-target crops) is minimal. Do not apply when the following conditions exist that increase the likelihood of spiny drift from intended targeu: high or gusty winds, high temperamra, Icw humidity, temperature inversions. To minimize spiny dri$ the applicator should be familiar with and take into accoun[thefollowing drift reduction advisory information. Additional information may be available from state enforcement agencies or the Cooperadve Extension on the application of this product The best drift management suategy and most effeedve way m reduce drift po[rndal are to apply large dropleu that provide sufficient coverage and control. Applying larger dropleu reduces drift potential, but will not prevent drift if applications are made rmproperly, or under untavorablc environmental wndidons (see WIND, TEMPERATURE AND HUMIDITY, and TEMPERATURE INVERSIONS). CONTROLLING DROPLET SIZE • Volume-Usehigh flow met nozzlesto apply the highestpractical spiny volume. Nozzles with higher rated flows product larger droplets. • Pressure-Do not exceed the nozzle manufacNrer'a recommended pressttres. For many nozzle types, lower pressure produces larger droplets. When higher flow rata are needed, use higher flow rate nozzles instead of increasingpressurc. • Number ofNOZZIcs-Use the minimum number afnoula thatprovide uniform coverage. • Noale Orientadon-Orirnting nozzles so that the spray is released parallel to the airstream produces larger dropleu than other orientations and is recom- mcnded pracdce. Significant deflection from the horizontal will reduce droplet siu and increase drift potential. • Nozzle Type-Use a nozzle type that is designed for the intended applicatioa. With most nozzletypes, narrower spiny anglesproduce larger dropleu. Consider using low-0rift nozzles. Solid stream nozzles oriented straight back produce the largest dropleu and the lowest drift Do not use nozzles producing a mist droplet spray. APPLICATION HEIGHT Making applications at the lowest possible height (helicopter, ground driven spiny boom) that is safe and practical induces exposure of dropleu to evaporation and wind. SWATH ADJUSTMENT Whrn applications are made with a crosswind, the swath will be displaced down- wind. Therefore, on the up and downwind edges of the treamrevt area, the applicaor must compensate for this diaplacemrnt by adjusting the path of the application equipmrnt (e.g. aircraft, ground) upwind. Swath adjustment distance should increase with increasing drift potential (higher wind, stuallcr dropleu, etc.). WLND Drift potential is lowest between wind speeds of 3-10 mph. However, many factors, including droplet size and equipment typo, determine drift potential at any given speed. Application should be avoided below 3 mph due m variable wind dircedon and high inversion potential. NOTE: Local terrain can influence wind pattems. Every applicator should be familiar with local wind pattems and how Ihry affect spray drift. TEMPERATURE AND HUMIDITY Whrn making applications in low relative humidity, set up equipment to produce Luger dropleu to compensate for evaporation. Droplet evaporation is most severe when condidons arc both hot and dry. TEMPERATURE INVERSIONS '~ Drift potenrial is high during a temperamrc inversion. Temperamrc inversions ms[ric[ vertical air mixing, which causes stnaB suspended dropleu to remain in a concentrated cloud, which can move in unpredictable dircetions due m the tight variable winds Common during inversions. Temperamrc inversions are characterizedby increasing temperamrcs with eldmde and arc common on nighu with hmited cloud cover and light to no wind. They begin m form az the sun sea and often continue into the morning. Then presence can be indicated by ground fog; however, if fog is not prcaent, inversions can also be identified by the movement of smoke fiom a ground souroe or an aircraR smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind condidons) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. WIND EROSION Avoid treating powdery dry or ]fight sandy soils when condidons am favorable for wind erosion. Under these conditions, the soil surface should first be sealed by rainfall or irigetion. SENSITIVE AREAS The pesticide should only be applied when the potential tort drift to adjacent srnsidve areas (e.g. residential areas, bodies of water, known habitat far threatened or endangercdspecies, or non-urger crops) is minimal (e.g. when wind is blowing away from the sensitive areas). LOW-VOLUME HAND-HELD SPRAY EQUIPMENT Thoroughly mix a 4. to 1 percent solution of ARSENAL in water. 7o deter- mine the proper pement solution of ARSENAL [o use, see the WEEDS CON- below.

HIGH-VOLUME SPRAY EQUIPMENT ARSENAL may be applied using high-volume spiny equipment For bat resulu, apply ARSENAL using the least amount of water practical ro obtain uniform coverage of the vegetation foliage. Using excessive spray volumes which cause mnoff from the plant foliage may result in reduced perfortnavice. When using spiny volumes greater than 60 gallons per acre, additional nonionic surfactant must be added at the rate of 1 quart per 100 gagons of spiny solution to provide optimum wetting and/or contact activity. A foam reducing agent may be added at [he recommended label rate, if needed. If desired, a spiny pattern indicator may be added a[ the recommended label rate. To mix the spiny solutioM determine the proper ARSENAL pinu per acre rate from the WEEDS CONTROLLED section of this label. IMPORTANT: DO NOT exceed recommended dosage rate per acre. DO NOT side-trim desirable vegetation with this Product Clean application equipment after using this product by thoroughly flushing with water. WEEDS CONTROLLED ARSENAL will pmvide postemergrncecontrol with residual wntrol of the follow- ing urge[ vegetation species at the raps listed. Residual control refers to control of newly gcrminadng seedlings in both annuals and perennials. ]n general, an- nual weeds may be controlled by prcemergcnce or postemergence applications of ARSENAL; whereas, for established birnnials and perennials, postemergrnce applications of ARSENAL arc recommended. ARSENAL should be used only in accordance with the recommendations on this label and the leaflet label.
