GROUP B HERBICIDE

For the pre-emergence control of certain annual grass and broadleaf weeds in fallow situations, sugarcane and peanuts and early post-emergence control of certain annual grass and broadleaf weeds in peanuts and sugarcane as specified in the Directions for Use table.

DIRECTIONS FOR USE
RESTRAINTS:
DO NOT apply to soils saturated with water.
DO NOT apply by aircraft.

WINTER CROPS
Situation: Fallow prior to planting Winter crops as directed in the follow crops table
State: Qld and Nthn NSW only
Weeds controlled: Barnyard Grass (Echinochloa colona), Liverseed Grass (Urochloa panicoides), Stink Grass (Eragrostis cilianensis), Blowaway Grass (Panicum decompositum), Button Grass (Dactyloctenium radulans), Pigweed (Portulaca oleracea), Yellow Vine (Tribulus terrestris), Mintweed (Salvia reflexa), Boggabri Weed (Amaranthus mitchelli), Dwarf Amaranth (Amaranthus macrocarpus), Peachvine/Cowvine (Ipomoea lonchophylla)
Rate per ha: 150 to 200 mL
Critical comments: Treatments may be applied from the end of the previous crop harvest but not less than 3 months prior to planting of Winter crop (refer to follow crops table).
Best results are obtained where treatments are applied to dry, weed-free soil prior to weed germination.
Treatments can be applied to standing crop residues. Sufficient rainfall is required after application and prior to weed emergence to wet soil to a depth of 5 cm. Use the higher rates for increased residual control of weeds or anticipated high weed pressure. Emerged weeds must be controlled by prior cultivation, or by application of a knockdown herbicide. Where infestation of emerged weeds is light, tank mix treatment with glyphosate or paraquat.
Cultivation following application of treatments may reduce pre-emergence weed control provided by IMPOSE.
Prolonged wet soil conditions following treatment will reduce the effective life of pre-emergence treatments. Weed escapes may require follow up application of knockdown herbicides.
DO NOT apply more than 200 mL/ha per season on cropland.
DO NOT apply in more than two successive seasons on cropland.
DO NOT overspray headlands.

SUGARCANE
State: Qld, NSW and WA only
Weeds controlled: Awnless Barnyard Grass (Echinochloa colona), Barnyard Grass (E. crus-galli), Blackberry Nightshade (Solanum nigrum),Blue Billygoat Weed (Ageratum houstonianum),Common Sida (Sida rhombifolia),Giant/ Black Pigweed (Trianthema portulacastrum), Glossy Nightshade (Solanum americanum),Green Amaranth (Amaranthus viridis),Green Summer Grass (Brachiaria subquadripara),Ipomoea spp., Guinea Grass (Panicum maximum),Liverseed Grass (Urochloa panicoides), Milkweed (Mexican Fire Plant) (Euphorbia heterophylla), Pigweed (Portulaca oleracea), Summer Grass (Digitaria cilaris)
Rate per ha: 300 to 400 mL
Critical comments: DO NOT apply more than once a year to the same crop.
Pre-emergence application:
PLANT CANE: Apply after planting and before emergence of the cane. On sandy soil, ensure thorough coverage of setts to a minimum depth of 5 cm. RATOON: Apply after harvest and before new cane growth appears.
Use the higher rates of IMPOSE for increased residual control of weeds or anticipated high weed pressure. Heavy trash layers may prevent the product from reaching the soil. Apply to weed-free soil prior to weed germination. Sufficient rainfall, or overhead irrigation, is required after application and prior to weed emergence to wet soil to a minimum depth of 5 cm. Emerged weeds must be controlled by prior cultivation, or application of an appropriate herbicide. Weed control can be improved under dry conditions or where incorporating moisture has been insufficient, by cultivating the treated soil above setts. Care needs to be taken to minimise exposure of untreated soil or setts.
Pre-emergence weed control may be limited on Krasnozem or red brown Ferrosol soil types, where moisture is not maintained in the top 5 cm of soil. Refer to Soil Type in the General Instructions.
Heavy rain and/or irrigation within 2 days following application may concentrate IMPOSE in the furrow and cause temporary yellowing and stunting of cane leaves. Prolonged wet soil and/or cool conditions can increase crop damage, especially in sandy soil. Normal growth will return when conditions become warm and drier. Weed escapes may require follow up application of an appropriate herbicide.
Contact Adama for advice on variety susceptibility before using this product (refer to the CROP SAFETY section of the label).

Weeds controlled: As above plus Crowsfoot Grass (Eleusine indica)
Rate per ha: 400 mL plus 3 L Pendimethex® Herbicide
Critical comments: Incorporate into the soil within 7 days of application, either by overhead irrigation, rainfall or mechanical incorporation, to a minimum depth of 5 cm. Read all directions for use in sugarcane as well as the Restraints and Follow Crops restrictions on the Pendimethex Herbicide.

Weeds controlled: As above plus control of those weeds expected with these rates of 250 g/L paraquat products alone
Rate per ha: 300 to 400 mL plus 1.2 to 1.6 L of 250 g/L paraquat product (e.g. Spraytop® 250 SL Herbicide)
Critical comments: Post-emergence application (in emerged cane):
ALWAYS tank mix IMPOSE with registered and appropriate rates of paraquat for the emerged weeds. Use the higher rates of IMPOSE for increased residual control of weeds or anticipated high weed pressure. Use the higher rates of paraquat for dense, more mature weeds.
Apply as a carefully directed inter-row spray to weeds and at the base of the plant, minimising contact with sugarcane foliage. Contact with sugarcane foliage may cause temporary crop damage observed as interveinal yellowing and reduction in crop biomass or crop height. Refer to Spraytop 250 SL Herbicide label re spray boom types and precautions. Reduce the incidence of “fines” by using the correct nozzles and operating pressures. Replace worn or old nozzles and calibrate equipment on a regular basis.
DO NOT cultivate within 1 hour of application.
Heavy rain and/or irrigation within 2 days following application may concentrate IMPOSE in the furrow and cause temporary yellowing and stunting of cane leaves.
DO NOT spray plants covered with heavy dew.
Prolonged wet soil and/or cool conditions can increase crop damage, especially in sandy soil. Normal growth will return when conditions become warm and drier. Pre-emergence weed control may be limited on Krasnozem or red brown Ferrosol soil types, where moisture is not maintained in the top 5 cm of soil. Refer to Soil Type in the General Instructions. Contact Adama for advice on variety susceptibility before using this product (refer to the CROP SAFETY section of the label).

GENERAL INSTRUCTIONS
All Applications
Reduce the incidence of “fines” by using the correct nozzles and operating pressures. Replace worn or old nozzles and calibrate
equipment on a regular basis.
Fallow application
IMPOSE can be applied in fallow prior to the planting of various crops as outlined in the Follow Crops table. IMPOSE is a preemergence herbicide, which is recommended to provide short term (6 to 12 weeks) pre-emergence control of Summer germinating grasses and broadleaved weeds in cultivated or uncultivated fallow. A green weed cover of greater than 50% will significantly reduce the length of pre-emergence weed control.
Sugarcane application
Pre-emergence: Where possible, apply to soil two days prior to incorporation. Incorporate with adequate irrigation or rainfall to a minimum depth of 5 cm. Incorporation by flood irrigation may result in loss of weed control. IMPOSE should be applied to plant or ratoon cane before the cane has emerged. When applying IMPOSE in moist conditions, allow weeds to germinate prior to application and apply mixed with an appropriate knockdown herbicide. Whenever emerged weeds are present, IMPOSE should be mixed with an appropriate knockdown herbicide.
Post-emergence: IMPOSE MUST always be mixed with registered rates of paraquat (ie Spraytop 250 SL Herbicide) and applied as a carefully directed inter-row spray to weeds and at the base of the sugarcane stalks, minimising spray contact with sugarcane foliage. DO NOT add crop oil to this mixture. Other surfactant or adjuvant is not required.
Peanut application
Pre-emergence: Apply to soil and incorporate with adequate irrigation or rainfall to a minimum depth of 5 cm.
Post-emergence: IMPOSE must always be mixed with an adjuvant as directed in the DIRECTIONS FOR USE section of the label.
Soil Type
Pre-emergence weed control with IMPOSE can be limited when applied onto soils with pH <5.0 and/or which contains high concentrations of iron (Fe) and/or aluminium (Al). These situations are common in soil types such as Krasnozems and red brown Ferrosols.

MIXING
IMPOSE is an aqueous solution. Part fill the spray tank with water, then with agitator running, add the required amount of product, then fill the tank with water. When tank mixing this product with other recommended compatible products, first add the other product to the tank and mix thoroughly before adding this product. For post-emergence applications in peanuts, add adjuvant after the addition of IMPOSE to the tank. No adjuvants or surfactants are required when IMPOSE is used alone for pre-emergence weed control or with paraquat.
DO NOT add crop oil when applied post-emergence with paraquat.

APPLICATION
DO NOT apply by aircraft.
Fallow Application: Apply with boom equipment in not less than 50 L/ha water using flat fan nozzles. Avoid overlap and do not overspray headlands.
Sugarcane: Ensure thorough coverage of soil and weeds with well-calibrated spray equipment. Apply in a minimum of 200 L water/ha using a nozzle configuration to generate a medium to coarse spray pattern for pre-emergence applications or medium spray pattern for post-emergence applications. Replace worn or old nozzles and calibrate equipment on a regular basis.
Peanuts: Apply with boom equipment in not less than 50 L/ha water using flat fan nozzles. Avoid overlap and do not overspray headlands. For post-emergence applications, IMPOSE should be applied a minimum of 2 hours before rainfall.

EQUIPMENT CLEAN-UP
Thoroughly flush all spray equipment with water following the use of IMPOSE and before use with other products.

COMPATIBILITY
IMPOSE is compatible with Pendimethex Herbicide, atrazine, glyphosate, paraquat, paraquat + diquat, Ally†, Garlon†, Touchdown† and 2,4-D.
It is NOT compatible with dicamba.

RESISTANT WEEDS WARNING
Adama IMPOSE Herbicide is a member of the imidazolinone group of herbicides. The product has the inhibitors-of-acetolactate-synthase (ALS) mode of action. For weed resistance management, the product is a Group B herbicide.
