Resistance Warning: RESISTANT WEEDS WARNING
Nufarm 2,4-DB 500 is a member of the Phenoxys group of herbicides. Nufarm 2,4-DB 500
has the disruptors of plant cell growth mode of action. For weed resistance management
Nufarm 2,4-DB 500 is a Group 4 herbicide. Some naturally occurring weed biotypes
resistant to Nufarm 2,4-DB 500 and other disruptors of plant cell growth 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 Nufarm 2,4-DB 500 or other Group 4
herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Nufarm
Australia Limited accepts no liability for any losses that may result from the failure of
Nufarm 2,4-DB 500 to control resistant weeds.
Precautions:
Protections: PROTECTION OF CROPS, NATIVE AND OTHER 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.
PROTECTION OF LIVESTOCK
SPRAY-GRAZING WARNING: Some pasture weeds can be controlled by Spray-Grazing,
a combination of herbicide treatment followed by heavy grazing 7-10 days later. Sprayed
weeds become more palatable to stock and a higher intake of some weed species after
spraying can cause stock deaths and other problems. Increased quantities of poisonous
plants may be eaten by stock when the Spray-Grazing technique is being used. Take carePage 3
if pastures are dominated by Caltrop, Capeweed, Cape tulip, Paterson’s curse (Salvation
Jane) or Variegated thistle. With Paterson’s curse preferably graze stock soon destined
for slaughter and avoid extended periods of grazing. Avoid grazing with young or breeding
stock. DO NOT graze horses or pigs in Paterson’s curse (Salvation Jane) infested pasture.
PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT
DO NOT contaminate streams, rivers or watercourses with this product or used containers.

Rye undersown with lucerne, medic or clover and clover has between 1-8 trifoliate leaves. Use lower rate for 2-
4 leaf weeds under good growing conditions. Apply to cereals
after the “double ridge” stage which is normally through tillering
after the main shoot has five leaves until booting (Z15-33). The
time to “double ridge” stage will vary depending on growing
conditions and variety.
Medic and Clover safety refer to the Critical Comments above.
Spot spraying (All Situations) Refer to Weeds Controlled in Lucerne 200-400 mL/100L Use lower rate for easy to kill weeds eg Fat hen or Variegated
water thistle. For harder to kill weeds eg Capeweed, Marshmallow, use
higher rate. Where difficult to wet, hairy or very thick weed
populations are present, add Nufarm BS1000® to the spray
mixture at a rate of 65 mL/100L water.
NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.Page 5
GENERAL INSTRUCTIONS
Spray applications and drift risk assessment
USE ONLY COARSE or larger spray quality.
Mixing
Mix with the required amount of water in the spray tank or mixing vessel. Apply using a low-volume boom spray fitted with fan jets, or by aircraft. Use mains or rain water for mixing. If not available, water with a hardness
of less than 500ppm (expressed as calcium carbonate equivalent) can be used but is not preferred. DO NOT tank mix Nufarm Liase with Nufarm 2,4-DB 500 in hard water for this may cause nozzle blockages.
Application
Apply using boom or spot spray equipment. Application must be uniform. Nozzle type, output, speed and pressure should be adjusted to deliver a Coarse spray quality in a minimum of 80L/ha by ground application and a
minimum of 40L of water per hectare by aerial application.
COMPATIBILITY
This product can be tank mixed with 900 g/Kg diuron for use in lucerne only. This mix can be very damaging to clovers. Nufarm 2,4-DB 500 is compatible with 800 g/kg Flumetsulam but not for control of Paterson’s curse
or Doublegee – refer to 800 g/kg Flumetsulam product label. The effectiveness of Dimethoate, Le Mat* and Imidan* may be reduced by alkaline hydrolysis if tank mixed with this product. For these situations the addition
of Nufarm Collide surfactant is recommended which should be added to the tank first. The addition of Nufarm CanDo Adjuvant can improve control of weeds under some conditions, for example moisture stress but may
also increase early effects on legumes. When tank mixing, add the required amount of compatible product (and surfactant if recommended) when the spray tank is nearly full and while continuously agitating. If left
overnight, agitate thoroughly before spraying.
