• EXCEPTION: In areas where soil moisture must exceed available water capacity to forma bed (e.g., certain regions in Florida), soil moisture content may exceed the 80%• e If appropriate measuring equipment is not used to determine whether the soil moisture in a top six inches of soil is between 60% to 80% available water capacity immediately prior the application; the USDA Feel and Appearance Method test may be used to estimate whether the 60% to 80% soil moisture content requirement is met: o For coarse textured soils(fine sand and loamy One sand) there must be enough moisture (50 - 751A of available water capacity) to fort. a weak ball with loose and clustered sand grains on fingers, darkened color, moderate"water staining, on fingers, Will not ribbon. o For moderately coarse textured soils (sandy loam and fine sandy loam) there must be enough moisture (50 - 75% of available water capacity) to form a ball with defined finger marks, very light soll/water staining on fingers, darkened color will not stick. o For medium texturedsoils (sandy clayloam,loam, and slit loam) there must be enough moisture (50 75% of available water capacity) to form a ball very 11 ht staining on fingers, darkened color, pliable, and forms a weak ribbon between gie thumb and forefinger. o For fine textured soils (clay, clay loam, and silty clay loam) there must be enough moisture (50 - 75% of available water capacity) to form a smooth ball with defined finger marks, light soli/water staining on fingers, ribbons between thumb and forefinger. Q For fields with more than one soil. texture, soil moisture content in the lightest textured (most sandy) areas must comply with this soli moisture requirement. The field may be divided into areas of similar soil texture and the soil moisture of each area should be adjusted as needed. Coarser textured soils can be fumigated under conditions of higher soli moisture than finer textured soils; however, If the soil moisture Is too high, fumigant movement will be retarded and effectiveness of the treatmentwiii be reduced. Previous and/or local experience with the soil to be treated or the crop to be planted can often serve as a guide to conditions that will be acceptable; If there is uncertainty in determining the soil moisture content of the area to be treated, a local extension service or soil conservationist or pest control advisor (agriculture consultant) should be consulted for assistance. • if there Is insufficient moisture throughout the top six inches below the surface of soil immediately prior to the application, the soil moisture must be adjusted. If there is adequate. soil moisture below six Inches, soil moisture can be brought to the surface by tillage priorto the application. To conserve existingsoii motsbire; Mega should be done as close to the time of application as possible. Application and Equipment Directforis • Systems using a gravity flow pesticide dispersing system must meter the pesticide into the water at the head of the field and downstream of a hydraulic discontinuity such as a drop structure or weir box to decrease potential for water source contamination from backflow if water flow stops. • Meter at a steady fate into 3 to 18 inches of water per treated acre during irrigation. IMPORTANT: Prior to starting the application, always inspect ditches and border areas to ensure containment of the Irrigation waters, Apply only into field head ditch. DO NOT APPLY INTO ANY LATERAL DITCHES. • Back flaw prevention devices must be Installed and in working order. • Tanks must be in good condition to ensure product does not spill or leak. • Dry disconnect couplings (closed transfer system) must be installed on all tanks and transfer hoses. • Tanks must have sealable covers on access ports. Tanks must have proper pesticide labels affixed to them. • All tanks, hoses,. fittings, valves and connections must be serviceable, tightened, sealed and not leaking. • Use only tanks, hoses and fittings designed to withstand the pressure of the system and resistant to metam. • For undiluted product, aluminum, brass, copper, galvanized iron, and zinc materials cannot be used. • To inject fumigant, use a metering system, effectively designed and consfnlcted of materials that era. compatible with the fumigant and capable of being fitted with system interlocking controls. • Flow rates must be calibrated and checked for each application. • All previous mater els applied with the system must be cleaned thoroughly prior. to fumigant application: • System must be flushed after application to totally remove all fumigant. MAXIMUM APPLICATION RATES FOR PRE -PLANT SOIL USES • Maximum application rate is 320 lbs metam sodlum/A and 75 gallons Sectagon 42/A• ISectdgon42 20t3.indd 13 q@yAUG U01i pq 6/12/2015 10:25:54 A.\7 1w
