General Information

GENERAL INSTRUCTIONS

Sectagon 42 is a water-soluble liquid. When applied to properly prepared soil, the liquid is converted into a gaseous fumigant. After a sufficient waiting period, the gas dissipates, leaving the soil ready for planting. Sectagon 42 is recommended for the suppression of weeds, plant parasitic nematodes, and soilborne fungi that cause reductions in the yield and quality of ornamental, food and fiber crops.

Sectagon 42 will suppress only those pests in the fumigation zone at the time of treatment. Recontamination may occur subsequent to the fumigant's dissipation from the soil.

Weeds and germinating weed seeds that are suppressed include Annual bluegrass, Bermuda grass, Chickweed, Dandelion, Ragweed, Henbit, Lambsquarter, Amaranthus sp. (Pigweed, Careless weed), Watergrass, Johnsongrass, Nutgrass, Wild morningglory, Purslane, Barnyardgrass, Crabgrass, Groundsel, Prickly lettuce, Pineappleweed, Nettleaf, Goosefoot, Nightshade, Shepherds purse, Stinging nettle, Malva, London rocket, and Fiddleneck. The best weed suppression is obtained when Sectagon 42 is applied to weeds that are actively growing.

The soil-borne plant pathogenic fungi suppressed include species of Verticillium, Rhizoctonia, Pythium, Phytophthora, Sclerotinia.

The plant parasitic nematodes which Sectagon 42 suppresses include Root knot, Lesion, Dagger, Lance, Needle, Pin, Reniform, Stunt, Stubby root, Sting and Spiral.

Note: Sectagon 42 will only suppress nematodes that are in the fumigated zone at the time of treatment. The fumigated zone is defined as the depth of penetration that Sectagon 42 achieves at the time of application. In Oregon and Washington, Sectagon 42 will only suppress Miloidogyne Chitwoodi. Other pests suppressed include symphilids or garden centipedes.

ENTRY-RESTRICTED PERIOD

Entry (including early entry that would otherwise be permitted under the Worker Protection Standard) by any person -other than a correctly trained and PPE-equipped handler who is performing a handling task listed on the labeling -is PROHIBITED from the start of the application until:

- 5 days (120 hours) after the application is complete for untarped applications, or

- 5 days (120 hours) after application is complete if tarps are not perforated and removed for at least 14 days following application (Note: persons installing, repairing, or monitoring tarps are handlers until 14 days after the application is complete if tarps are not perforated and removed during those 14 days), or

- 48 hours after tarps perforation is complete if they will not be removed for at least 14 days following application, or

- Tarp removal is completed if tarps are both perforated and removed less than 14 days after application.

NOTE: see Tarp Perforation and/or Removal section on the labeling for requirements about when tarps are allowed to be perforated.

APPLYING SECTAGON 42

Use of Diluted Sectagon 42

Do not store the diluted product. Use Sectagon 42promptly after it has been mixed with water. In dilute solutions in water Sectagon 42 decomposes over a period of days. Although Sectagon 42 is stable in its concentrated form, it is unstable in acid dilutions.

GENERAL INSTRUCTIONS FOR SPRINKLER SYSTEMS

NOTICE: Do not operate irrigation systems without safety valves or other devices to prevent back siphoning of Sectagon 42 into water sources. Irrigation water treated with Sectagon 42 should be maintained on the treated area until the water is absorbed by the soil. The tank containing Sectagon 42 must be connected to the discharge side of the irrigation pump or other pressurized equipment attached to the irrigation line. Do not apply in irrigation systems that result in overlapping application of Sectagon 42. Do not apply when weather conditions favor drift from target areas.

PREPARING FOR PLANTING AFTER APPLICATION OF SECTAGON 42

Effect of Rain

If a Sectagon 42 application is rained on less than 24 hours after treatment, lack of suppression at and near the soil surface may result.

Recontamination

Precautions must be taken to prevent recontamination of treated soil with weed plant pathogenic fungi and plant parasitic nematodes. Use clean seeds and/or plants. Before farm equipment is driven into the treated area, it should be rinsed free of the untreated soil from other fields.

Interval Between Treatment and Planting

Because Sectagon 42 can be harmful to germinating and/or living plants, an appropriate interval must be observed between soil fumigation and planting. On well-drained soils which have a light to medium texture and which are not excessively wet or cold following application, planting can begin 14 to 21 days after treatment. If soils are heavy or especially high in organic matter, or if they remain wet and or cold (below 60c F or 15c'C) following application, a minimum interval of 30 days should be observed.

Aeration before planting

Soils including soils high in clay or organic matter, should be allowed to aerate and dry thoroughly after treatment with Sectagon 42 During cold and/or wet weather, frequent shallow cultivation can aid the escape of Sectagon 42 from the soil.

Testing for Dissipation of Sectagon 42

After the waiting period has passed, if there are any questions about the complete escape of Sectagon 42 from the soil, transplant a seedling into the treated soil. If the plant develops normally without any signs of chemical injury, crop planting can begin.

Limitations, Restrictions, and Exceptions

ADDITIONAL RECOMMENDATIONS

MINT

When infestation is limited to small spots in a field, spread can be reduced by treating the soil with 75 gallons Sectagon 42 per treated acre (1.5 pints per 100 sq. ft.) using injector blade or thin shank injector rig with injectors spaced at intervals to cover the desired treating width.
