GROUP G HERBICIDE

For selective weed control of broadleaf weeds and some grasses as specified in the Directions for Use table.

DIRECTIONS FOR USE
Restraint:
DO NOT disturb weeds by cultivation or sowing for 1 day following application to annual weeds and 7 days for perennial weeds to ensure herbicide absorption, unless specified in the CRITICAL COMMENTS

Trees (Fruit & Nut) and Vines at least 3 years old as a dormant application, including:
GRAPEVINES, OLIVE TREES, POME FRUIT, (eg. APPLE, PEAR, NASHI, QUINCE), STONE FRUIT (eg. APRICOT, CHERRY, NECTARINE, PEACH, PLUM), TREE NUTS (eg. ALMONDS, MACADAMIA, PECAN, WALNUT)
Weeds controlled: Refer to Weeds Controlled list
Time of application: Weed free soil
Rate: 3 or 4 L/ha
Critical comments: DO NOT apply CAVALIER once bud swell has occurred. Apply to freshly cultivated weed free soil. Use the higher rate when longer residual control is required (up to 4 months). Where grass weeds are expected to be a major problem, or when control of a wider weed spectrum is required, mix the lower rate with 4-5 L Cameo® 500 per treated hectare. Read and follow all label directions.
Time of application: Emerged weeds present (4-6 leaf stage)
Rate: 3 or 4 L/ha
Critical comments: DO NOT apply CAVALIER once bud swell has occurred. Use the higher rate when longer residual control is required (up to 4 months). When light infestations of weeds are present, apply as a tank mix with Wipe-Out® or Spraytop® to produce both knockdown and residual control. Read and follow all label directions. Where weed growth is large and dense, weeds must be eliminated prior to application of CAVALIER, using Wipe-Out or mechanical means.
Macadamias: Apply in 250 to 500 L water/ha. Apply after harvest to prevent spray contacting nuts. Avoid spray contact with the foliage and stem. DO NOT apply to nuts on the ground.

Fruit and Nut Trees, Vines including:
GRAPEVINES, OLIVE TREES, POME FRUIT, (eg. APPLE, PEAR, NASHI, QUINCE), STONE FRUIT (eg. APRICOT, CHERRY, NECTARINE, PEACH, PLUM), TREE NUTS (eg. ALMOND, MACADAMIA, PECAN, WALNUT)
Weeds controlled: Annual Weeds Refer to Weeds Controlled list and Wipe-Out 360 label
Time of application: Actively growing emerged weeds
Rate: 75 mL/ha plus Wipe-Out 360 at recommended label rate.
Critical comments: Addition of CAVALIER to Wipe-Out will improve knockdown and increase the speed at which treated weeds develop visible symptoms of phytotoxicity (compared to results achieved with Wipe-Out applied alone), and give control
Annual Nettles (Urtica spp.).
For rates of Wipe-Out, refer to the appropriate label. Read and follow all label directions.
DO NOT apply the tank mix of Wipe-Out and CAVALIER near trees or vines less than 3 years old unless they are effectively shielded from spray and spray drift.

Weeds controlled: Most annual grasses and broadleaf weeds Refer to Weeds Controlled list and Spray.Seed 250 or Tryquat* 200 labels
Time of application: Emerged weeds present
Rate: 250 mL plus Spray.Seed 250 or Tryquat 200 at recommended label rates OR 25 to 30 mL / 100 L plus Spray.Seed 250 or Tryquat 200 at recommended label rates
Critical comments: The addition of CAVALIER to Spray.Seed 250 or Tryquat 200 will improve control of small flowered mallow, evening primrose and other weeds sensitive to CAVALIER.
Apply as a tank mix with Spray.Seed 250 or Tryquat 200, refer to the appropriate label and follow all label directions.

Tropical and Subtropical Fruit (inedible peel) including:
AVOCADO, CHERIMOYA, CURTARD APPLE, DURIAN, FEIJOA, GYAVA, JACKFRUIT, KIWIFRUIT, LONGAN, LYCHEE, MANGO, MANGOSTEEN, PAPYA, PASSIONFRUIT, PERSIMMON, RAMBUTAN, STAR APPLE)
Weeds controlled: Refer to Weeds Controlled list
Time of application: Weed free soil
Rate: 4 L/ha
Critical comments: Best results are obtained when applied to moist soil free of weeds.
Time of application: Emerged weeds present
Rate: 4 L/ha
Critical comments: If weeds are present CAVALIER should be applied as a tank mix with recommended rates of Wipe-Out, Spray.Seed or Spraytop 250.

BRASSICA CROPS, CABBAGES, CAULIFLOWER, BROCCOLI
Weeds controlled: Refer to Weeds Controlled list
Time of application: Weed free soil
Rate: 1.5 to 2 L/ha
Critical comments: Apply CAVALIER to prepared ground 4 to 7 days prior to transplanting. If soil is dry, irrigation or rainfall is required prior to transplanting for activation of CAVALIER. Utilise transplanting techniques which cause minimal soil disturbance. Excessive soil disturbance will lessen herbicidal activity.
Use the higher rate in situations where weed pressure is known to be heavy.

ONIONS
(seeded)
Weeds controlled: Blackberry Nightshade
Time of application: Hook leaf stage
Rate: 50-100 mL/ha
Critical comments: DO NOT exceed 100 mL/ha at the hook leaf stage as excessive crop damage may occur.

Weeds controlled: Docks, Crowsfoot/Storksbill, Fumitory Weed (Pink and White Weed), Hogweed (Wireweed), Plantain, Sorrel, Volunteer Potato, Potato Weed, Milk Thistle, Deadnettle, Common Cotula, Groundsel
Time of application: 1,5 to 2,5 true leaf stage
Rate: 350-500 mL/ha
Critical comments: Best results are obtained when the hook leaf stage treatment is followed by a further application of CAVALIER when onions are at the 11/2 to 21/2 true leaf stage.
Apply CAVALIER in at least 100 L/ha water at pressures below 150 kPa.
DO NOT exceed 150 kPA pressure because excessive crop damage could result.
Multiple treatments may be applied provided the total dose does not exceed 2 L/ha in one season. For control of other weeds, use in a program with other registered herbicides.
Note: Can cause flecking, twisting or stunting of onion plants although such symptoms are normally short-lived.
DO NOT apply in conditions of very high humidity. DO NOT apply to weeds or crops which are stressed by prevailing weather conditions, disease or mechanical damage.
DO NOT use wetting agents or other adjuvants.

TOBACCO
Weeds controlled: Refer to Weeds Controlled list
Time of application: Weed free soil
Rate: 4 L/ha
Critical comments: Use to control weeds along spray lines only. DO NOT apply to tobacco crop.
Apply to soil after solid-set irrigation system has been laid out in the field. CAVALIER should be applied to a moist soil. Where very small weeds (2-3 leaf) emerge prior to spraying, the addition of a wetting agent to the spray mixture is necessary for effective control. Should the weeds be more advanced, the addition of 2 L Tryquat 200 is required. Avoid spray drift.

Prior to Sowing - WINTER CEREALS, COTTON
Weeds controlled: Annual Weeds Refer to Weeds Controlled list and Wipe-Out 360 or Wipe-Out CT labels
Time of application: Actively growing emergent weeds
Rate: 75 mL/ha plus Wipe-Out CT or Wipe-Out 360 at recommended label rates
Critical comments: Addition of CAVALIER to Wipe-Out CT or Wipe-Out 360 will improve knockdown and increase the speed at which treated weeds develop visible symptoms of phytotoxicity (compared to results achieved with Wipe-Out CT or Wipe-Out 360 applied alone), and give control of Annual Nettles (Urtica spp.) and Marshmallow (Malva parviflora).
For rates of glyphosate, refer to the appropriate label.

GENERAL INSTRUCTIONS
CAVALIER® Herbicide is a selective herbicide for the control of certain annual grass and broadleaf weeds in dormant apples, grapes, peaches, pears, plums, apricots, almonds, macadamia, duboisia, tobacco, coffee, pyrethrum, winter cereals, tropical/subtropical crops, brassicas, onions, Eucalyptus and Pinus spp. and other forestry trees, applied either to weed free soil or to seedling weeds up to the 4 to 6 true-leaf stage.
CAVALIER applied to well prepared, weed free soil should not be disturbed or incorporated after application. Weed control for up to 6 months can be expected with high label rates, but spot treatment of escape weeds or perennial grasses may be necessary with knockdown herbicides. When CAVALIER is applied to seedling weeds at the 4 to 6 leaf stage, a non-ionic surfactant such as Wetspray 1000 should be added at recommended rates to improve activity, where suggested in the CRITICAL COMMENTS.
CAVALIER can also be used at low rates as a “spike” to improve the weed spectrum of knockdown herbicides such as glyphosate and paraquat or diquat/paraquat mixtures.

RESISTANT WEEDS WARNING
CAVALIER Herbicide is a member of the Diphenyl ether group of herbicides. The mode of action of CAVALIER is to inhibit protoporphyrinogen oxidase. For weed resistance management CAVALIER is a Group G Herbicide. Some naturally occurring weed biotypes resistant to CAVALIER and other Group G herbicides may exist through normal genetic variability in any weed population. The resistant weeds can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by CAVALIER or other Group G herbicides.
Since the occurrence of resistant weeds is difficult to detect prior to use, Adama Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of CAVALIER to control resistant weeds.

TIMING
Residual Control
For optimum residual weed control, CAVALIER should be applied to the soil surface prior to weed emergence after all other agricultural operations, such as mechanical cultivation and re-shaping of irrigation furrows, have been completed. The area should be left undisturbed during the time period for which weed control is desired.
When applied to seedling weeds, they should be young and actively growing.
Weed control for up to 6 months is expected with high label rates, but spot treatment, with knockdown herbicides, for escape weeds and perennial grasses may be necessary.
Post-emergence weed control
For optimum post-emergence weed control, CAVALIER + glyphosate tank mixes should be applied to small seedling weeds up to 4 to 6 true-leaf stage. Use of a non-ionic surfactant such as Wetspray 1000 is recommended to improve activity. Weeds should be actively growing and free from environmental stress (drought, cold, insect attack, nutrient deficiency). Cultivation after treatment and prior to or at planting is benefical for final fallow weed control.

MIXING
When using CAVALIER alone, fill the spray tank at least one-third full with clean water, add the recommended amount of CAVALIER while the pump and agitator are running, then complete filling the spray tank. A non-ionic surfactant, if required by label directions, should be added near the end of the filling process to minimise foaming.
When tank mixing with Cameo 500, add to one-third filled tank and then add the CAVALIER during the filling operation. Maintain agitation during mixing and until spraying is completed.

Cavalier + Glyphosate Tankmixes
Ensure thorough agitation when mixing, filling the spray tank and during application, irrespective of glyphosate formulations used. Follow recommended order and directions for tank mixing CAVALIER and glyphosate. Use all spray mix immediately after preparation.
DO NOT tank mix CAVALIER and glyphosate without agitation.
DO NOT allow mix to stand unagitated.
DO NOT store CAVALIER and glyphosate tank mixes.
DO NOT mix other agrochemical products with CAVALIER and Wipe-Out CT tank mixes.

APPLICATION
Spray equipment should be calibrated carefully before use.
CAVALIER should be applied uniformly as a directed treatment to the base of tree and vine crops using flat fan or off-centre nozzles. Complete coverage of seedling weeds is required for maximum knockdown effect. Ensure both weed foliage and the soil surface are sprayed.
Apply using a vehicle mounted boom, calibrate to deliver a droplet spectrum classification defined as medium by the American Society of Agricultural Engineers (ASAF) Standard S572, using water volume of 250 to 500 litres per hectare for bare soil or 100 to 1350 litres per hectare when seedling weeds (4 to 6 leaf stage) are treated. Use the higher volumes where weed density is high.
Tank mixtures of 75 mL/ha of CAVALIER with glyphosate herbicides should be applied in 30 to 200 litres spray volume per hectare. For maximum residual control, CAVALIER should NOT be incorporated or disturbed after application.

CROP SAFETY
CAVALIER may be applied as directed around dormant peach, plum, apricot, almond, apple and pear trees and grape vines of all ages when applied at rates of less than 1.0 L/ha. When applied at 3.0 L/ha and above, the trees and grape vines should be at least 3 years of age.
DO NOT apply CAVALIER once bud swell has occurred when using rates greater than 1.0 L/ha.
Duboisia seedlings and mature plants will tolerate “over-the-top” applications of CAVALIER. When using the 75 mL/ha rate, CAVALIER may be applied as directed prior to sowing winter cereals.

SAFE SOWING INTERVALS
CAVALIER at up to 75 mL/ha may be safely applied 1 day prior to planting broadacre crops such as cereals (wheat, barley, oats, triticale), canola, pulses (lupins, faba beans, field peas) and undersown pastures (lucerne, clover, medics, ryegrass, phalaris, cocksfoot) and 7 days minimum prior to planting cotton or soybeans, provided minimum tillage planting equipment is used with minimal soil disturbance. Inversion, mixing of surface soil with that in the planting zone or covering seed with treated soil may result in injury to emerging crop seedlings.
Avoid covering the seed with soil treated with CAVALIER during the planting operation to minimise crop injury.
CAVALIER has residual soil activity, especially when applied at rates greater than 75 mL/ha and on small-seeded horticultural crops. Plantback intervals in the following table for horticultural crops must be observed if more than 75 mL/ha CAVALIER has been applied.
