GENERAL INSTRUCTIONS

VORAXOR HERBICIDE is a non-selective burndown and selective pre-emergence herbicide.

For knockdown uses: VORAXOR HERBICIDE is a fast acting contact herbicide and aids in control of weeds through a process of membrane disruption. The foliar uptake of VORAXOR HERBICIDE is rapid and plant desiccation can occur within 4 days of application. Application of VORAXOR HERBICIDE to emerged weeds should target small actively growing weeds.

VORAXOR HERBICIDE may also be used alone with a suitable adjuvant for control of a range of broadleaf weeds as per the directions for use table. When used in situations where emerged weeds are present the addition of glyphosate or paraquat based herbicides will broaden weed spectrum and may improve final control.

For residual control: At label rates of 200 mL/ha to 240 mL/ha VORAXOR HERBICIDE provides residual control of a wide range of broadleaf weeds as well as the suppression of key grass weeds. Crop selectivity of VORAXOR HERBICIDE when applied for residual control of weeds is achieved through a combination of metabolic as well as placement selectivity.

Use rates for residual control are 200 mL/ha within 7 days prior to sowing (0-7 days before sowing) or 240 ml/ha if greater than 7 days before sowing (7-21 days before sowing). The 240 mL/ha rate should not be used within 7 days of sowing as there is increased chance of crop damage occurring.

In situations of dry sowing, or where conditions are less than ideal for even pre-emergence herbicide incorporation (rough seed bed, presence of excess soil clods, increased surface residues, etc) the ability to increase rate slightly and delay sowing for at least 7 days can improve weed control performance and provide more utility to end users. Refer to APPLICATION section for factors that may adversely affect weed control.

Crop safety: For residual weed control, apply pre-sowing and incorporate by sowing (IBS) ensuring good physical separation of the planted seed and herbicide. The seeder should be set up to move herbicide treated soil out of the planting furrow to provide crop safety. Avoid throwing treated soil into adjacent crop rows. Wide points and harrows of any type must not be used at or after the seeding operation that incorporates VORAXOR HERBICIDE. In addition to moving treated soil out of the sowing furrow, seeder setup should also result in minimizing the chance of treated soil falling back into the furrow. Seeder type alone does not guarantee herbicide and seed separation so attention to setup at planting is required.

Using VORAXOR HERBICIDE in conjunction with a grass weed pre-emergence herbicide - If planning to use a specific grass weed pre-emergent herbicide such as Luximax®, Sakura*, Boxer Gold*, Overwatch*, prosulfocarb, triallate or trifluralin as a tank mix with VORAXOR HERBICIDE, additional caution is required as increased crop damage may occur. Tank mixes of multiple herbicides requiring physical separation results in higher loading of total herbicide and therefore imposes a greater potential impact on crops. Refer to guidelines on both product labels for guidance on factors that contribute to performance and crop tolerance ensuring all parameters of all product labels are met. Increasing sowing depth to >30mm, reducing speed of travel at sowing and avoiding use when heavy rainfall is forecast soon after planting will be most effective measures for increasing physical separation of seed and herbicides to gain increased crop selectivity, particularly on sandy or light soils and where furrow wall collapse occurs. A decision to mix pre-emergent herbicides should be made based on weed burden and resistance management issues where some potential impact on crop selectivity is outweighed by weed control needs. Avoid throwing treated soil into adjacent crop rows. Refer to guidelines on both product labels for guidance on factors that contribute to performance and crop tolerance ensuring all parameters of all product labels are met.

SYMPTOMS

VORAXOR HERBICIDE when applied post emergence to weeds is rapidly absorbed through the foliage of plants. Within a few hours following application, the foliage of susceptible weeds will show signs of desiccation, and in subsequent days necrosis and death of the plant. In a pre-emergent situation VORAXOR HERBICIDE is taken up by roots and hypocotyl resulting in lack of germination of weed seeds. Any affected plants that germinate may show signs of necrosis particularly in tissue that has been in contact with treated soil such as stems and first emerging leaves.

If crop damage occurs from pre-emergence use pattern, symptoms are necrosis of 1st emerged leaf at axis of leaf and stem resulting in leaf 1 senescing and dropping from the plant. In trials this symptom has not been associated with negative impact on crop yield. In the case of winter pulse crops, if crop damage occurs from pre-emergence use pattern, symptoms are necrosis of cotyledons and potentially stems at the soil surface. In trials this symptom has not been associated with negative impact on crop yield.

COMPATIBILITY

When Applying VORAXOR HERBICIDE to emerged weeds Hasten Spray Adjuvant or an alternate high quality methylated seed oil (MSO) should always be used. Crop oil concentrates or non-ionic surfactants are not recommended when using VORAXOR HERBICIDE for control of emerged weeds.

For most uses as per the Directions for Use VORAXOR HERBICIDE may be tank mixed with a good quality glyphosate or paraquat based herbicide. If mixing with paraquat it is essential that the correct mixing sequence is followed requiring VORAXOR HERBICIDE to be added to the tank prior to the selected paraquat product. Refer to MIXING section below.

VORAXOR HERBICIDE is also physically compatible with the following products in a two-way tank-mix (maintain constant agitation throughout): Arcade*, Ally*, Avadex* Xtra, Amicide* Advance 700, Amicide* 625, Balance*, Basta*, Boxer Gold*, Dual Gold*, Glean*, Garlon*, glyphosate, Logran*, Lontrel Advanced*, Luximax®, Overwatch*, paraquat, prosulfocarb, Nufarm Surpass* 475, Rifle*, Rustler*, Sakura*, Simazine 900 WDG, Spinnaker 700 WDG, Terbyne Xtreme*, triallate, trifluralin and Verdict* 520 EC.

As formulations of other manufacturer’s products are beyond the control of BASF, and the quality of water may vary with location, all mixtures should be tested prior to mixing commercial quantities. When determining physical compatibility of a product not listed above, or in mixes with VORAXOR more than a two-way mix, conduct a jar test prior to mixing commercial quantities.
