Depic 75-D Herbicide

Tips For Use

General Instructions:

• Do not apply to crops or weeds which are not actively growing or to plants which may be stressed (not actively Growing) due to prolonged periods of extreme cold, moisture stress (water-logged or drought affected) or previous herbicide treatment, as crop damage or reduced levels of control may result.
• Do not use it in high winds.
• Do not spray if rain is likely to occur within 4 hours.
• In some states, some uses of Depic 75-D are controlled by legislation. Check with your local Department of Agriculture or Primary Industry for details.
• In Tasmania, Depic 75-D may only be used from 15 April to 15 September unless otherwise permitted by the Registrar of Pesticides.

Restraints:

• Do not exceed the maximum application rate of 15 L/ha (4500g ae/ha).
• Do not apply if heavy rains or storms are forecast within 3 days.
• Do not irrigate to the point of runoff for at least 3 days after application.
• Do not exceed the maximum daily application rate by backpack spraying of 13.3L/day.
• Do not apply to crops or weeds which are not actively growing or to plants which may be stressed (notactively growing) due to prolonged periods of extreme cold, moisture stress  water-logged or drought affected) or previous herbicide treatment, as crop damage or reduced levels of control may result.
• Do not apply close to or on areas containing roots of desirable vegetation, where treated soil may be washed into areas growing, or to be planted too, desirable plants, or on sites where surface water from heavy rain can be expected to run off to areas containing, or to be planted to, susceptible crops or plants.
• Do not move soil that may have been sprayed to areas where desirable plants are to be grown.
• Picloram, one of the active constituents in this product remains active in the soil for extended periods depending on the rate of application, soil type, rainfall, temperature, humidity, soil moisture and soil organic matter. In some states, some uses of this product are controlled by legislation.
• Check with your local Department of Agriculture or Primary Industry for details.

Precautions: Re-Entry Period:

• If re-entering treated areas before the spray has dried, workers should wear overalls, elbow-length gloves and water-resistant footwear.
• Clothing must be laundered after each day’s use.

Mixing:

• Mix only with water.
• It will not mix with oil or diesel fuel.
• Mechanical or bypass agitation in the spray tank is recommended, and it should be maintained during spraying.
• Quarter-fill the spray tank and add the required amount of herbicide in the following order:
  • Wettable powder or water-dispersible granules
  • Suspension concentrates (atrazine flowable)
  • Aqueous concentrates (e.g. Conquest Depic 75-D Herbicide, 2,4-D Amine)
  • Emulsifiable concentrates
  • Surfactants or crop oil.

Adjuvants:

• Do not add surfactants (such as BS-1000/Wetter 1000) or crop oils (such as Uptake Spraying Oil) unless specifically recommended to do so in the directions for use (Tables 1 and 2).

Application:

Conquest Depic 75-D Herbicide may be applied by:

• Ground boom: Spray using accurately calibrated equipment that delivers 50 – 100 L water/ha. Do not use less than 200 L/ha in sugacane. When treating maize and sorghum, the risk of crop injury will be reduced if dropper nozzles are used to avoid spraying the growing point of the crop. Misting machines and boom jet sprayers should not be used to treat crops.
• Aircraft: Use accurately calibrated equipment to deliver not less than 20 L water/ha. Do not use less than 50 L/ha in sugar cane.
• High volume: Apply using a calibrated handgun with D5 or D6 (2 – 3 mm) nozzle plate and operated at 400 – 500kPa. Spray to thoroughly wet the weed, usually 2,500 – 3,500 L water/infested ha is required.
• Stem injection: Treat only trees with good sap flow. Make injection cuts at 13 cm spacing around the diameter of the tree at waist height or at 15 cm spacing at ground level. The cuts should be made using a 5 to 7 cm wide narrow-bladed axe. The cut must be made through the bark and deep enough to place all the chemicals in contact with the sapwood. Treat each stem of a multi-stem tree where possible. Inject the chemical mix into each cut immediately after the cut is made. Apply the mix with a vaccinator or similar equipment that can be accurately calibrated or a tree injector that can apply the measured dose at or near ground level. Injection at or near ground level is essential in the Traprock area of south-eastern Queensland and is preferred for optimum results in Bimble box (poplar box) areas.
• Cut stump: Cut the trees as close to the ground as practicable, leaving stumps no higher than 10 cm. Spray, swab or brush the chemical mix immediately to the freshly cut surface so as to thoroughly wet the surface. If the cut surface is oily, add a non-ionic wetting agent to assist penetration.
• Frilling: Make successive overlapping cuts into the sapwood around the entire circumference of the base of the tree. Spray to thoroughly wet the frilled area.
• Injecting spray into the centre of weed: Inject using a vaccinator or similar equipment. 1 mL of treatment mix into the growing point for each 2.5 cm of the plant stem diameter. (See Zamia palm).

Compatibility:

Depic 75-D Herbicide is compatible with:

• Atrazine (600 g/L flowable or an equivalent granular product)
• 2,4-D Amine (625 g/L)
• Diquat
• Metsulfuron-methyl
• Topik/Snooker (Clodinafop-Propargyl & Cloquintocet-Mexyl)
• Glyphosate 450 g/L
• Glyphosate 480g/L

Protection of Crops, Native and 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.
• Avoid spray drift and vapour movement onto susceptible crops such as cotton, tobacco, tomatoes, vines, lupins, fruit trees and ornamentals.
• Crops susceptible to Conquest Depic 75-D Herbicide include, but are not limited to, peas, lupins, Lucerne, navy beans, soybeans and other legumes; cotton, fruit, hops, ornamentals, potatoes, safflower sugarbeet, sunflower, tobacco, tomatoes, vegetables and vines.
• Do not plant susceptible crops within 12 months of applying winter or summer cereal use rates of this product.
• Cereal crops and grasses can be sown safely after Depic 75-D Herbicide.
• Rates in excess of these will result in more persistent soil residues.
• Therefore, do not rotate susceptible plants until an adequately sensitive bioassay or chemical test shows that no detectable picloram is present within the soil.

Protection Of Livestock:

• Do not graze or cut treated crops or plants for stock food except as specified under withholding periods.
• Poisonous plants may become more palatable after spraying and stock should be kept away from these plants until they have died down.

Protection of Wildlife, Fish, Crustaceans and the Environment:

• Very toxic to aquatic life.
• Do not contaminate streams, rivers or watercourses with this product or used containers.
