<br />application period. Flush the system with only enough water to clear Imes, If the soil surface
<br />dried quickly, reseal It
<br />with 15 minutes of water once a day forthe next day or two.
<br />To prevent runoff .of treatment solution during sprinkler application, do not exceed the
<br />infiltration rate of the solution into the soil. Should runoff occur, isolate it from growingg crops
<br />and water sources. Once collected, reapply it to the treated area. See use restrictions In
<br />"CHEMIGATION" section.
<br />CHECK FLOOD (BASIN), FURROW AND BORDER
<br />Meter Sectagon 42 at a. steady rate into water during Irrigation. Use 40 to 75 gallons of
<br />Sectagon 42 per acre, depending upon the kind of ppest and depth desired,. in 3 to 18 inches
<br />of water per acre. See use restrictions in "CHEMIGATION' section.
<br />DISC APPLIED METHOD
<br />Spray Sectagon 42 immediately in front of disc. Use 15 to 75 gallons per acne. Follow
<br />immediately with a roller to smooth and compact the soil surface.
<br />DRIP IRRIGATION
<br />Sectagon 42 may be injected into drip irrigationsystems prior to planting. The area must be
<br />calculated in accordance with the size of the band treated. Apply 40 gallons per broadcast
<br />acre. in one acre fnch of water (27,000 gallons). The resulting concentration is 700 ppm on a
<br />weight basis. (Example: if the emitters irrigate 1.0% of each acre then use 5 gallonsSectagon
<br />42 in 2,700 gallons water). Inject continuously. Do not slug treat. See use restrictions in
<br />"CHEMIGATION" section.
<br />APPLICATION TO BED OR ROWS
<br />ROTARY TILLER OR POWER MULCHER APPLICATION
<br />Spray Sectagon 42 immediately in frontof the tiler ormulcher,, setto the depth where control
<br />is desired, Use 37.5 to 75 gallons per treated acre (or see crop -specific directions in the
<br />Additional Use Instructions section of this label), Follow immediately with a roller, power roller
<br />or bedshaper to seal soil surface. Light watering or a tarp after rolling may be used to help
<br />prevent fumigant escape.
<br />IMPORTANT SOIL TREATMENT PRECAUTIONS
<br />Crops to be hilted: For crops that require soil movement (hilling) prior to or after planting,
<br />Incorporate Sectagon 42 to a depth that will allow the tillage required to occur without
<br />penetrating below the depth of treatment (sea application specific requirements in the Good
<br />Agricultural Practices section of this label).
<br />Crops to be bedded: For crops to be bedded, care must be taken that exposed sides of
<br />raised beds are not cracked or open compared to the powerrolled surface. If necessary, add
<br />power rollers of the required height or other sealing equipment to the ends of the bedding
<br />equipment to seal the sides.
<br />Note: The use of Sectagon 42 for the suppression of weeds, weed seeds and shallow
<br />inhabiting.soilfungi requires that NO SOIL CULTIVATION OCCUR FOLLOWING TREATMENT
<br />until time of planting.
<br />This. method of treating soil with Sectagon 42 will not be effective for the suppression of
<br />nematodes outside the treated zone. This.method of Sectagon 42 application can be used in
<br />combination with other soil fumigants to suppress the nematodes persisting on the surface 1
<br />to 6 inches of soil normally not suppressed with Injected soil fumigants.
<br />Zone of treatment will be limited by diameter of applicator If pest is deeper than applicator
<br />can treatto, use a different method. For further information contact your local agricultural
<br />extension service orthe manufacturer.
<br />SOIL INJECTION (Pre4ormed Beds)
<br />Sectagon 42 atthe rate of 50 to 75 gallons pertreated acre (110 1.5 pints per 100 sq.ft), may
<br />be injected into preformed plant beds followingthe directions given above under soil injection.
<br />If a wider treated band is desired, space 2 or more Injectors (shanks, blades, fertilizer wheels,
<br />etc.) at desired intervals to cover the desired treating width, Seal Immediately.
<br />If Sectagon 42 is injected into established plant beds to terminate growth of a previous crop,
<br />and to fumigate the bed in preparation for planting a subsequent crop, the terminated crop
<br />should not be used for any food or feed purposes after Sectagon 42 has been applied.
<br />SOIL INJECTION (At Bed Forming Operation)
<br />Sectagon 42 may be infected during the bedding or row building, process, or to preformed
<br />beds, using one of the following delivery systems: (1) single narrow knife blade (2) a series
<br />of narrow knife blades set no more than 5 inches apart, (3) a spray blade, (4) tiered shanks,
<br />(5) spray rake or (6) similar equipment that places Sectagon 42 in contact with the pest to
<br />be controlled at suppressed, The use rate for the above operations is 37.5 to 75 gallons per
<br />treated acre (or see crop -specific directions in the Additional Use instructions section of this
<br />label), Reduced rates will vary depending upon the actual width of the treated band desired.

<br />__
<br />Apply the Sectagon 42 at the desired depth in the soil and follow immediately with the soil
<br />capping operation, bedding process, or roller/packer to seal the fumigant into the soil.
<br />SOiL COVERING METHOD
<br />(BED -OVER METHOD)
<br />Sectagon 42 may be sprayed or dripped onto the soil immediately -ahead of bed -shaping
<br />equipment. Follow immediately with a bedshaper, roller press wheel, or similar device, or
<br />cover with an adequate amount of soil to seal the fumigant into the soil. The recommended
<br />rate of Sectagon 42 Is 40 to 75 gallons per acre oftreated soil, approximately equivalent to
<br />.5 to 1.5pints per 100 linear ft. of 12 -inch wide row.
<br />DRIP IRRIGATION
<br />During pre -Irrigation, check drip tape for uniform distribution and repair If necessary. Apply
<br />15 to 75 gallons Sectagon 42 per treated acre (0.25 to 1.5 pints per 100 sq. ft, of treated
<br />soil) using enough water to thoroughly wet entire desired treatment zone. During the entire
<br />Irrigation period, inject Sectagon 42 continuously Into drip line as close as possible to
<br />treatment area, Two or more lines per bed may be needed to ensure full coverage.
<br />Weed suppression will not be satisfactory if too much water Is applied (if 80.% available water
<br />eapacitgts exceeded). An adequate concentration of Sectagon 42 must be present at the time.
<br />of weed seed germination in order to be effective. See use restrictions In "CHEMIGATION"
<br />section.
<br />DRENCH APPLICATION.ON BEDS OR ROWS
<br />Sectagon 42 maybe applied to finished beds in enough water to soak at least2 inches deep
<br />for suppression of shallow seeded weeds. To avoid contamination by untreated soil, do not
<br />disturb the treated area. Apply 15 to 75, gallons of Sectagon 42 per treated acre.
<br />ADDITIONAL USE INSTRUCTIONS
<br />TOBACCO PLANT BEDS
<br />Fall applications are recommended wherever possible. Read and follow DIRECTIONS FOR
<br />USE carefully. Treatmentin the South should generally be made before November 30,
<br />Drench Method: Apply 2 gallons Sectagon 42 in 150 to 200 gallons of water per 100
<br />sq. yd. Application may be made with sprinklers, sprayers with nozzles or any suitable
<br />equipment Follow directions given above for seed bed treatment. Do not apply more than
<br />75 gallons of Sectagon 42 per acre.
<br />SYMPHYLID SUPPRESSION
<br />Soil should be in good seed bed condition to a depth of 8 to 10 inches. Maintain adequate
<br />moisture during,spring season. Treat during July -August when.symphylids are in the upper
<br />soil surface. Apply 15 gallons Sectagon 42 per acre using blade or chisel injector. Inject
<br />below level of symphylid concentration, usually 6 to 8 inches. Pack soil immediately after
<br />application.
<br />NOTE: Sectagon 42 Will only suppress nematodes which are in the fumigated zone at the
<br />time of. treatment.
<br />POTATOES
<br />For suppression of potato ,pests such as Root knot nematodes, Weed seeds, Verticullum
<br />dahlias (Early maturity disease).
<br />Apply 301o75 gallons Sectagon 42 peracre using injectors (shanks, blades, fertilizerwheels,
<br />plows, etc.) Follow immediately with a bedshapar, roller press wheel or similar device or cover
<br />with an adequate amount of soil to seal the fumigant into the soil.
<br />Sprinkler system preplanf application —Use 37;5 to 75 gallons of Sectagon 42 per acre.
<br />Inject Into a sprinkler system that can deliver an even water distribution for the area being
<br />treated. inject all of the Sectagon 42 needed for the area covered and apply in enough water
<br />to reach the desired treatment depth. Soil temperature should be in the. range of 35°1` to
<br />90°Fin the treatment zone. Soil moisture immediately prior to treatment must be 60 to 80%
<br />of available water capacity down to 24" level. Soli condition must facilitate even moisture
<br />penetration without runoff. Do not apply when plants are present. See 6se restrictions in
<br />CHEMIGAMW section.
<br />NOTE:-Sectagon 42 will suppress Root knot. nematodes in the fumigated zone at the time
<br />of treatment. The fumigated zone is defined as the depth of penetration that Sectagon 42
<br />achieves at the time of application.
<br />If high numbers or deep nematodes are identified, anticipate nematodes to build up
<br />throughoutthe growing season. Some damage will occuruniessadditional action is taken.
<br />Soctagon 42 has no sail residual and reinfestation of a field can occurfrom numerous sources
<br />such as deep nematode populations, seed pieces, irrigation water, equipment contamination
<br />and blowing wind.
<br />EARLY MATURITY DISEASES OF POTATOES iN OREGON
<br />Apply .30 gallons Sectagon 42 per acre using Injectors (shanks, blades, fertilizer wheels,
<br />plows, etc.) Follow immediately with a bedshaper, roller press wheel or similardevice orcover
<br />with an adequate amount of soil to sealthe.fumigant into the soil.
