Description

Conquest Depic 75-D Broadleaf Herbicide

Conquest Depic 75-D Herbicide controls annual and perennial broadleaf weeds across pastures, winter and summer cereals, sugarcane, fallow, and non-crop areas throughout Australia. It contains 300 g/L 2,4-D (as the triisopropanolamine salt) and 75 g/L Picloram (as the triisopropanolamine salt) in a liquid formulation. Together, these two Group I actives combine phenoxy and pyridine modes of action to deliver both contact and residual broadleaf weed control in a single product.

Conquest Crop Protection Pty Ltd formulated Depic 75-D for broadacre, pastoral, and non-crop weed management. The label covers over 60 weed species across multiple situations, with application methods including ground boom, aircraft, high volume handgun, stem injection, cut stump, and frilling. This range of methods makes it suitable for both paddock-scale broadleaf weed knockdown and targeted woody weed control on non-crop land.

Weeds Controlled by Conquest Depic 75-D Broadleaf Herbicide

The label covers weed control across the following cropping and land management situations:

Situation Key Weeds Controlled
Winter cereals Climbing buckwheat, Saffron thistle, Sowthistle, Docks
Summer cereals (NSW and Qld) Thornapple, Amaranthus spp., Noogoora burr, Bladder ketmia
Sugar cane (Qld) Sicklepod (at labelled rates with 2,4-D amine)
Fallow (pre-sowing winter cereals) Bathurst burr, Morning glory, Parthenium weed, Sesbania pea
Pastures and non-crop areas Lantana, Paterson’s curse, Skeleton weed, Star thistle, Ragwort, Bindweed
Woody weed control Eucalyptus spp. regrowth, Hawthorn, Rubber vine, Tree-of-Heaven

Frequently Asked Questions

Q.Can Conquest Depic 75-D cause damage from spray drift?

A.Yes. This is a phenoxy herbicide, and it causes severe damage to susceptible crops, including cotton, tomatoes, vines, fruit trees, and ornamentals. Apply only when wind speed is between 3 and 15 km/h, and use Very Coarse droplets or larger as required by the label.

Q.What is the withholding period for livestock grazing?

A.Do not graze or cut treated crops or pastures for stock food for 7 days after application. For treated sugarcane, the withholding period extends to 8 weeks before harvest and before cutting for stock food.

Q.Which products is Conquest Depic 75-D compatible with?

A.The label approves mixing with atrazine (600 g/L flowable or equivalent granular), 2,4-D amine (625 g/L), diquat, metsulfuron-methyl, Topik, and glyphosate (450 g/L and 480 g/L). Mix only with water, not with oil or diesel fuel.

Q.What application methods does the label permit?

A.Approved methods include ground boom (50–100 L/ha), aircraft, high volume handgun, stem injection, cut stump, and frilling. Boom sprayers must deliver Very Coarse droplets at a boom height of 0.5 metres or lower above the target canopy.

Q.Does Picloram leave residues in the soil?

A.Yes. Picloram persists in the soil for extended periods, with duration influenced by application rate, soil type, rainfall, and temperature. Do not plant susceptible crops within 12 months of applying cereal use rates of this product.

For stem injection and cut stump work, use the diluted mix at rates specified in Tables 5 and 6 and apply immediately after cutting. Buffer zones for both aquatic and terrestrial sensitive areas apply. Refer to the full label for mandatory buffer zone distances and spray drift requirements.

Tips For Use

Restraints:

  • Do not apply to crops or weeds that are not actively growing, or to plants stressed by extreme cold, moisture stress (waterlogged or drought-affected), or previous herbicide treatment.
  • Do not spray if rain is likely within 4 hours (general use) or 6 hours (under spray drift instructions).
  • Do not apply unless the wind speed is between 3 and 15 km/h at the application site.
  • Do not apply under surface temperature inversion conditions. These conditions typically occur one to two hours before sunset and persist until one to two hours after sunrise.
  • Do not apply if crop or weeds are stressed due to dry or excessively moist conditions.
  • Do not move soil that has been sprayed to areas where desirable plants are to be grown.
  • In some states, certain uses of this product are controlled by legislation. Check with your local Department of Agriculture or Primary Industries.
  • Users must make an accurate written record of each spray application within 24 hours and retain those records for a minimum of 2 years.

Mixing Instructions:

  • Mix only with water. This product will not mix with oil or diesel fuel.
  • Quarter fill the spray tank, then add ingredients in this order: wettable powders or water dispersible granules; suspension concentrates (e.g. atrazine flowable); aqueous concentrates (including Conquest Depic 75-D Herbicide); emulsifiable concentrates; then surfactant or crop oil if directed.
  • Maintain mechanical or bypass agitation in the spray tank during mixing and spraying.
  • Do not add surfactants (such as BS-1000) or crop oils (such as Uptake Spraying Oil) unless specifically directed in the Directions for Use tables.

Cleaning Spray Equipment:

  • After use, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose, then clean all tank, pump, line, and nozzle filters.
  • To rinse: quarter fill the tank with clean water, circulate through pumps, lines, hoses, and nozzles, then drain. Repeat twice.
  • To decontaminate before spraying sensitive crops: wash and rinse the system, then quarter fill with an alkali detergent solution (e.g. liquid Surf, OMO, or Drive at 500 mL per 100 L water) and circulate for at least 15 minutes. Do not use chlorine-based cleaners. Drain fully, then flush with clean water.
