GENERAL INSTRUCTIONS

CROP SAFETY

Chickpeas: Application of Smart Soxx 750 Herbicide PSPE to chickpeas planted in sandy or gravelly soils, or soils low in clay or organic matter may result in crop damage. Heavy rains after the application of Smart Soxx 750 Herbicide may cause crop damage, particularly in sandy or gravelly soils. Application of Smart Soxx 750 Herbicide + simazine in sandy or gravelly soils may result in severe crop damage.

Varietal Tolerance: Smart Soxx 750 Herbicide is not recommended for use with the chickpea variety Yorker. Application of Smart Soxx 750 Herbicide post-sowing pre-emergence to crops of Yorker variety chickpeas can result in unacceptable crop damage and may result in yield loss.

Crop rotation recommendations: Smart Soxx 750 Herbicide may be applied to chickpea crops where the following crop will be chickpeas, or where the land will be left fallow. Prolonged dry periods or cold conditions may result in extended re-cropping intervals, even if rainfall exceeds the required amount (listed in the table below). Heavy rainfall after an extended dry period may result in the reactivation of Smart Soxx 750 Herbicide. This can lead to transient bleaching or crop stunting. Use on soils with a pH less than 7.0 has not been extensively tested, and may result in extended re-cropping intervals. Cultivation is recommended prior to re-cropping. Minimum re-cropping intervals apply for all crops following Smart Soxx 750 Herbicide application.

Three key guidelines for maintaining crop safety when using Smart Soxx 750 Herbicide in sugarcane:

1. DO NOT apply to soils with a low binding potential, that is with a C.E.C. below 4.5 meq/100 g, or an O.C. of 1.0% or less (unless C.E.C. is greater than 9.5 meq/100 g).

2. DO NOT apply to areas which have poor drainage or poor root development.

3. Add paraquat to Smart Soxx 750 Herbicide to minimise foliar uptake when applying as a broadcast spray to plant cane.

Smart Soxx 750 Herbicide is absorbed to organic matter and clay particles in the soil. Soils with low organic carbon (O.C.) and cation exchange capacity (C.E.C.) have a reduced capacity to absorb the herbicide in the soil, which may result in the herbicide leaching past the weed root zone into the cane root zone. Crop root uptake of Smart Soxx 750 Herbicide may result in phytotoxicity, which is evident as bleaching of leaves. To minimise the risk of crop root uptake, Smart Soxx 750 Herbicide is not recommended for use on soil with a C.E.C. below 4.5 meq/100 g, or an O.C. of 1.0% or less (unless C.E.C is greater than 9.5 meq/100 g).

These values should be determined through soil analysis prior to using Smart Soxx 750 Herbicide. Refer to your local reseller or Crop Smart representative to assist you with interpretation of your soil analysis results.

The use of Smart Soxx 750 Herbicide on newly limed soil could cause severe crop damage, please contact your local Crop Smart representative for advice prior to use of Smart Soxx 750 Herbicide in this situation.

Smart Soxx 750 Herbicide has been field tested on all important commercial varieties of sugarcane (available up to September 2002) without any evidence of varietal tolerance variation. If you are contemplating the use of Smart Soxx 750 Herbicide on experimental or minor varieties of sugarcane, small test areas should be treated to establish suitable tolerance before treating large areas. For further information on varietal tolerance please contact your Crop Smart representative.

MIXING

Partly fill the spray tank with water. Start agitation. Add the correct amount of Smart Soxx 750 Herbicide to the spray tank with the agitation system running. When tank-mixing with paraquat, ensure that Smart Soxx 750 Herbicide is added to the spray mixture first, followed by paraquat to ensure thorough mixing. Continue agitation while topping up the tank with water and while spraying. Use prepared spray mixture on day of preparation. DO NOT allow spray mixture to stand overnight.

TANK MIXTURES

Read and follow all label directions including restraints, spray drift restraints, mandatory no-spray zones, critical comments, withholding periods, regional use restrictions and safety directions for the tank mix product.

APPLICATION

Sugarcane: Apply in a minimum spray volume of 250 L/ha. For best results, flat fan nozzles are recommended. Select the lowest pressure (within the recommended nozzle operating range), to reduce drift. Use a nozzle size that delivers a medium to coarse droplet at the selected operating pressure.

Smart Soxx 750 Herbicide can be applied to hot and dry soils, without the risk of breakdown by sunlight. This ultraviolet stability removes the need for immediate soil incorporation of the product. Smart Soxx 750 Herbicide is activated by rainfall or irrigation, which is required to carry the herbicide into the root zone of the germinating weeds. Deep germinating weeds (e.g. Wild Radish) may not be adequately controlled in years where rainfall is low (<15 mm).

Weed escapes may occur after spraying Smart Soxx 750 Herbicide if weed germination occurs before the chemical is activated OR carried to the depth of the weed root zone. Under prolonged dry conditions a greater quantity of rainfall or irrigation may be required for effective activation of the product. Under these conditions, shoots of germinating weeds may intercept the Smart Soxx 750 Herbicide band and appear affected, but may not be controlled. Weeds that do not turn completely white within days of emergence must be sprayed with an appropriate knockdown herbicide. To avoid weed escapes, it is recommended to allow weeds to germinate, and then apply Smart Soxx 750 Herbicide in tank mixture with paraquat at an appropriate label rate to provide additional weed knockdown.

Soil movement from irrigation or cultivation may result in poor weed control from Smart Soxx 750 Herbicide. DO NOT incorporate Smart Soxx 750 Herbicide by flood irrigation or with high-pressure water cannons if excessive soil movement is expected, particularly if the soil is in a loose, dry condition. Best results are achieved where rainfall or low-pressure overhead irrigation carries the herbicide downward in an even band to the depth of the weed root zone

COMPATIBILITY

Sugarcane: Smart Soxx 750 Herbicide may be tank-mixed with paraquat formulations at the appropriate label rates for each product. Smart Soxx 750 Herbicide may be tank-mixed with diuron (900 g/kg) at the rate recommended in the ‘Directions for Use’ table on this label. Smart Soxx 750 Herbicide is also compatible with atrazine (900 g/kg) and Actril DS (apply no more than 500 mL/ha in combination with Smart Soxx 750 Herbicide).

Chickpeas: Smart Soxx 750 Herbicide should not be tank-mixed with trifluralin.

SPRAY EQUIPMENT CLEAN-UP

To avoid injury or exposure to non-target crops, thoroughly clean all mixing and spray equipment, including pumps, nozzles, lines and screens with a good quality tank cleaner immediately after using Smart Soxx 750 Herbicide. Before disassembling nozzles, filters and other parts for cleaning, thoroughly wash down the exterior of the spray equipment with a pressure hose. A more rigorous cleaning process is recommended, particularly before spraying very sensitive crops (e.g. canola).

To rinse: After cleaning the tank as above, quarter fill the tank with clean water and circulate through the pump, lines, hoses and nozzles. Drain and repeat the rinsing procedure twice.

To clean: Empty the tank completely and drain the whole system. Without entering it, thoroughly wash inside the tank using a pressure hose. Alternatively, if the tank is fitted with in-tank rinse nozzles, activate these nozzles to thoroughly rinse the inside of the tank. Drain the tank and clean any tank, pump, line and nozzle filters.

To decontaminate: Quarter fill the tank and add a liquid alkali detergent at 500 mL/100 L of water or a chlorine bleach (4% chlorine) at 300 mL/100 L of water and circulate throughout the system for at least fifteen minutes. Drain the whole system. Nozzles, screens, relief valves, dump lines, caps and taps at the end of spray lines, tank lids, flow meters, lines to pressure gauges, external tank indicators, induction hoppers and transfer systems should be removed/pulled apart and cleaned separately. Pay special attention to by-pass lines from pressure relief or dump valves to the main tank. To remove chlorine bleach, flush the system with clean water and allow to drain. Finally, flush the system with clean water and allow to drain.

Rinse water should be discharged onto a designated disposal area or if this is unavailable, onto unused land away from desirable plants and their roots, and water courses.

RESISTANT WEEDS WARNING

GROUP H HERBICIDE

Smart Soxx 750 Herbicide is a member of the isoxazole group of herbicides. Smart Soxx 750 Herbicide is a herbicide which inhibits 4-hydroxyphenyl- pyruvate dioxygenase (4-HPPD). For weed resistance management Smart Soxx 750 Herbicide is a Group H herbicide. Some naturally-occurring weed biotypes resistant to Smart Soxx 750 Herbicide and other Group H herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Smart Soxx 750 Herbicide or other Group H herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Crop Smart Pty Ltd accepts no liability for any losses that may result from the failure of Smart Soxx 750 Herbicide to control resistant weeds.

PRECAUTIONS

Re-entry period: DO NOT allow entry into treated areas for 12 hours after treatment. When prior entry is necessary, wear cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical resistant gloves. Clothing must be laundered after each day’s use.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT

DO NOT contaminate streams, rivers or waterways with this product or the used containers, as this product may cause injury to non-target plants and vegetation, particularly aquatic plants and algae.

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS

DO NOT apply under weather conditions, or from spraying equipment, which could be expected to cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures.

STORAGE AND DISPOSAL

Store in the closed, original container in a cool, well-ventilated area. Do not store for prolonged periods in direct sunlight.
