For the control of certain broadleaf and grass weeds in green beans, navy beans, sweet corn, corn, poppies, green peas, pumpkins and kabocha, as specified in the DIRECTIONS FOR USE table

DIRECTIONS FOR USE:
RESTRAINTS
DO NOT apply to green beans, navy beans, green peas, pumpkins, kabocha, corn or sweet corn crops sown in soils
with a cation exchange capacity (CEC) of less than 5 meq / 100 g (or cmol / kg) OR soils with a clay content of less than 10% AND organic carbon content of less than 2%.
DO NOT apply through aircraft or irrigation equipment.

POPPIES
(2 – 6 leaf stage)
Weeds Controlled: Pinkweed / Fumitory (Fumaria spp), Cotyledon to 2 leaf stage
Rate Per ha: 1.4 L
Critical Comments: Apply FRONTIER-P when the pinkweed is at the cotyledon to 2 leaf stages and the crop is at the early 2 leaf to 6 leaf stages. A follow-up spray of Starane must be applied within 15 days for complete control of pinkweed. For improved post-emergent control of other weeds, such as hogweed (Polygonum aviculare), fat hen (Chenopodium album) and blackberry nightshade (Solanum nigrum), Command Herbicide should be tank mixed with FRONTIER-P. Do NOT tank mix FRONTIER-P with Brodal.

SWEET CORN, CORN (MAIZE), GREEN BEANS, NAVY BEANS, GREEN PEAS, PUMPKINS, KABOCHA
Weeds Controlled: Toad Rush (Juncus bufonius)
Rate Per ha: 150 to 200 mL
Critical Comments: Apply at or immediately after sowing and before crops and weeds emerge. Apply to moist soil. Rain or irrigation following application is desirable. Use rates toward the higher end of the range where longer residual control is required.

Weeds Controlled: Crowsfoot Grass (Eleusine indica)
Rate Per ha: 500 mL to 1.0 L

Weeds Controlled: Wild Hops / Apple of Peru (Nicandra physaloides), Summer Grass (Digitaria ciliaris), Barnyard Grass (Echinochloa crus-galli)
Rate Per ha: 700 mL to 1.0 L

Weeds Controlled: (Amaranthus spp.), Fat Hen (Chenopodium album), Blackberry Nightshade (Solanum nigrum), Giant or Black Pigweed (Trianthema portulacastrum), Sow or Milk Thistle (Sonchus oleraceous), Brazilian White-eye (Richardia brasiliensis), Shepherd’s Purse (Capsella bursa-pastoris)
Rate Per ha: 1.0 L

Critical Comments: FRONTIER-P is mainly absorbed by the emerging shoot (coleoptile). FRONTIER-P must be present in the top soil layer as the weeds germinate and the coleoptiles pass through the treated soil layer. Apply at or immediately after sowing and preferably before crops and weeds germinate. Emerged, or soon to emerge, weeds present at the time of application are unlikely to be controlled. Delays in applying FRONTIER-P after sowing, particularly if irrigation or rain moistens soil and initiates germination before the application of FRONTIER-P, will lead to reduced control.
Apply to moist soil if possible. If applied to dry soil, irrigation or rain must follow soon after application for best results. Irrigation or rain is required within 7 days after application.
FRONTIER-P is best applied to freshly prepared soil with fine tilth and as soon as possible after sowing.

Weeds Controlled: 
Suppression of;
Ryegrass (Lolium spp.), Subterranean Clover (Trifolium subterraneum), White Clover (Trifolium repens), Pigweed (Portulaca oleracea), Pale Pigeon Grass (Setaria glauca), Stonecrop (Crassula sieberiana), Scrambling Speedwell (Veronica persica), Pennyroyal (Mentha pulegium), Bittercress (Coronopus didymus) 
Rate Per ha: 1.0 L
Critical Comments: Use the lower rate on light textured, low organic matter, low CEC soils and the higher rate on heavier textured soils as per the tables below. Refer to CROP SAFETY section.
FRONTIER-P can be used on trickle irrigated fields if rain or overhead irrigation follows application or the trickle irrigation sufficiently moistens the soil surface.
Untreated soil thrown onto treated areas will reduce weed control. Do not disturb the FRONTIER-P treated soil layer as this may lead to weed emergence.
Application to crop trash covering the soil surface may lead to reduced control.
Do not use on soil in which crops will be transplanted nor over already transplanted crops.

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.

WITHHOLDING PERIODS
GRAZING

OR CUT FOR STOCKFEED FOR 4 WEEKS AFTER APPLICATION.

GREEN BEANS, NAVY BEANS, GREEN PEAS, CORN, SWEET CORN, PUMPKINS, KABOCHA: NOT REQUIRED WHEN USED AS DIRECTED.
POPPIES: DO NOT HARVEST FOR 100 DAYS AFTER APPLICATION.

GENERAL INSTRUCTIONS
FRONTIER-P is a selective pre-emergent herbicide for control of weeds in sweet corn, corn (maize), green beans, navy beans, green peas, pumpkins and kabocha,. FRONTIER-P controls susceptible germinating seedlings before or soon after they emerge from the soil. FRONTIER-P will not control emerged weeds except cotyledon to two leaf pinkweed (fumitory) in 2 to 6 leaf poppy crops. FRONTIER-P will be most effective when incorporated by rainfall or overhead irrigation prior to weed germination. Reduced weed control may occur when trickle irrigation is used and there is insufficient soil surface moisture.

MIXING
Add the required amount of herbicide directly to the partly filled spray tank with agitation running. Complete filling and maintain agitation until spraying is complete.

APPLICATION
Apply FRONTIER-P with a calibrated boom spray equipped with flat fan nozzles in a spray volume of 200 to 300 L/ha. Do NOT apply by aircraft.
For medium quality spray (BCPC/ASAE);
DO NOT apply if waterbodies, watercourses or wetlands are within 20 metres downwind of the application area. DO NOT apply if non-target vegetation is within 15 metres downwind of the application area. For fine quality spray (BCPC/ASAE) or an undefined spray quality;
DO NOT apply if waterbodies, watercourses or wetlands are within 50 metres downwind of the application area. DO NOT apply if non-target vegetation is within 40 metres downwind of the application area.

EQUIPMENT CLEAN-UP
Clean application equipment thoroughly using a strong detergent or tank cleaner. Rinse equipment thoroughly before re-use.

COMPATIBILITY
FRONTIER-P is compatible with Command, atrazine, Gesaprim and Stomp. Do NOT mix FRONTIER-P with Brodal.

RESISTANCE WARNING
GROUP K HERBICIDE
FRONTIER-P Herbicide is a member of the amide group of herbicides. The product has the herbicides with diverse sites of action mode of action. For weed resistance management, the product is a Group K herbicide.
Some naturally occurring weed biotypes resistant to the product and other amide 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 this product or other amide herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, BASF Australia accepts no liability for any losses that may result from the failure of this product to control resistant weeds.

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS
Do NOT apply under weather conditions or from spraying equipment that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures.
Do NOT transplant brassicas, plant potatoes or sow crops other than green beans, kabocha, green peas, pumpkins, corn and sweet corn within 6 months of application of FRONTIER-P.
Do NOT sow carrots or pyrethrum within 12 months of application of FRONTIER-P.

CROP SAFETY
Injury to green beans, kabocha, green peas, pumpkins, corn and sweet corn may occur at label rates on soils with very low cation exchange capacity (CEC). Soils containing low levels of clay and organic matter normally have a low CEC. Do NOT apply to green beans, kabocha, green peas, pumpkins, corn or sweet corn crops grown on soils with a cation exchange capacity (CEC) of less than 5 meq / 100g (or cmol / kg) OR soils with a clay content of less than 10 % AND organic carbon content of less than 2%.
