COTTON
Weeds controlled: Annual broadleaf weeds and some annual grasses
State: Qld, NSW only
Rate / ha: 1-2 kg
Critical comments: Pre-emergence: Apply at planting or within 7 days of planting and prior to cotton emergence. Seed should be planted at least 4 to 5 cm deep and soil compacted over seeds by a normal planter packer wheel. Use high rate on soils high in clay or organic matter content.
DO NOT use on light sandy soils as injury to crop may occur.
DO NOT make a second pre-emergent application to the same
field during the same crop year as injury to the crop may result.
Apply in 300-450 L water/ha.
Post-emergence (lay-by): Use the higher rate on heavier soil types high in clay and/or organic matter. DO NOT use on light sandy soils low in organic matter as injury to the cotton may result.
Apply when cotton is at least 30 cm high, or immediately after the last cultivation. If emerged annual weeds (15 cm or less in height) are present add 170 mL Wetspray 600/100 L water to the spray solution. Apply DIURON 900 WDG as a directed spray to cover the area beneath cotton plants and between rows. Avoid spray contact or drift on to cotton plants as injury may result.
DO NOT apply more than once per season.
DO NOT re-plant treated areas to any crop within one year after last application as injury may result, except cotton, corn or sorghum (grain sorghum only) which may be planted in the spring following treatment.
Apply in 300-500 L water/ha.

LUPINS
(on light soils only)
Weeds controlled: Annual Ryegrass, Capeweed, Clovers, Medics, Doublegee, Wild Radish, Wild Turnip and suppression of Brome Grass, Dock, Sorrel, Wild Oats and Wireweed
State: WA only
Rate / ha: 1.1 kg
Critical comments: Use through boom spray equipment only. Apply in a minimum of 50 L water/ha. Higher volumes of water will give more even application. Must be applied prior to crop emergence.

Weeds controlled: Cape Weed, Crassula, Double Gee, Erodium, Wild Radish, Wild Turnip, Toad Rush
State: All States
Rate / ha:
IBS 830 g-1.1 kg
PSPE 550-830 g
Critical comments: Incorporated by sowing (IBS): Apply to bare moist soil prior to sowing or at sowing and incorporate by the sowing operation. Use the lower rate on light sandy soils.
Post Sowing Pre-Emergent Application (PSPE): Apply as a post sowing pre-emergent application to moist soil before weed or crop emergence. Use the lower rate on light sandy soils. Application should not be made to excessively ridged or waterlogged soils. Sow the crop at least 5 cm deep. Trilogy® or Spinnaker* may be tank mixed at the recommended rates.

State: WA only
Rate / ha: 550 g plus 500 mL of a 720 g/L metolachlor to improve suppression of Ryegrass

Critical comments: Post planting application only for full cut sowing systems that leave a relatively smooth surface, e.g. standard combine or airseeder. Apply post plant pre-emergent to crop within 3-4 days of planting.
Pre plant application only for sowing systems (e.g. No Till or Zero Till) which leave open slots or furrows, or where seed is sown along the bottom of the furrow. Even the soil surface where harrowed after sowing. Apply within 7-10 days pre plant.
Soil Types – use lower rates on sandy surfaced soils with a low organic carbon or clay content.
Caution: DO NOT use on grey or white sands. Crop to be planted at least 35mm deep. Crop tipping and yellowing may occur particularly when heavy rain falls after sowing. Shallow sown crops are more at risk.

GENERAL INSTRUCTIONS
Before opening, carefully read Directions For Use, Precautionary Statements, Safety Directions and First Aid Instructions.
Application should be made to moist soil before weeds emerge unless otherwise recommended. Sufficient moisture in the form of rain or irrigation is necessary after application to move the chemical into the weed root zone.
Add Wetspray where recommended.
Thoroughly clean all traces of this product from application equipment immediately after use, otherwise injury to desirable vegetation may result when equipment is used again. Flush tank, pump, hose and boom with several changes of water after removing nozzle tip and screens (clean these parts separately). Keep from contact with fertilisers, insecticides, fungicides and seeds.

RESISTANT WEED WARNING
Adama DIURON 900 WDG Herbicide is a member of the Urea group of herbicides. DIURON 900 WDG has the Inhibitor of photosynthesis at photosystem II mode of action. For weed resistance management DIURON 900 WDG is a Group C herbicide. Some naturallyoccurring weed biotypes resistant to DIURON 900 WDG and other Group C herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by DIURON 900 WDG or other Group C herbicides.
However resistance should not be assumed without first viewing the method of application, the coverage and the timing of application.
Resistance to DIURON 900 WDG cannot be predicted and may occur at any time. It is not due to a fault in the product and Adama Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of DIURON 900 WDG to control resistant weeds.

MIXING
Part fill tank with CLEAN water (50%). Commence vigorous agitation. Add granules steadily.
DO NOT dump. Ensure complete dispersion before filling to volume with water. Continue agitation during spraying. DO NOT leave spray solution in tank overnight.
Agitation: An efficient by-pass agitator or means of mechanical agitation should be employed when using this product.

COMPATIBILITY
This product is compatible with diquat, Spraytop 250 SL, amitrole, 2,4-D Amine and Ester, 2,4-DB, MCPA, Strike-Out 500 EC, Le-Mat* and Tackle 750 WP. Add the required amount of product when the spray tank containing DIURON is nearly full and being continually agitated. This product is not compatible with Tribunil*, Rogor*, Matavan*, Hoegrass* and Bayleton*.
As formulations of other manufacturers’ products are beyond the control of Adama, all mixtures should be tested prior to mixing commercial quantities.

SELECTIVE USE IN CROPS
For selective use in crops it is important to apply recommended rates correctly. DIURON 900 WDG is most effective when applied to soil which has been well tilled (clod free) and is free of weeds and trash. Where not recommended for overall application, care should be taken to avoid spray drift onto fruit or foliage. Wetting agents should only be used where specified.

REPLANTING RESTRICTIONS
Crop Rotations: DO NOT replant treated areas to any crop within two years after last spray unless otherwise stated.
Cotton – DO NOT replant treated areas to any crop within 1 year after last spray. Except cotton, corn or grain sorghum which may be planted in the spring of the following year.
Sugarcane – Treated areas can be replanted to pineapple or sugar cane 1 year after last spray.

CROP SAFETY
Heavy rains after application of this product may cause severe crop damage, risk must be assumed by user.
DO NOT use on sandy or gravelly soils or soils low in organic matter.
Avoid contact of sprays with crop foliage or fruit.
