Unichem IPU 500
For the control of annual meadow-grass and broad-leaved weeds in winter wheat, spring wheat, winter barley, rye and triticale.
A suspension concentrate containing 500g/l (44.6% w/w) isoproturon.
DIRECTIONS FOR USE
Do not apply to spring barley, durum wheat, undersown cereals or those due to be undersown.
Avoid spray drift onto neighbouring crops.
Avoid overlapping spray swaths
Thoroughly wash all spraying and measuring equipment immediately after use.
UNICHEM IPU 500 can be applied before or after weed emergence. Weed control is by root uptake and foliar action.
When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominating. A weed species is considered resistant to a herbicide if it survives a correctly-applied treatment at the recommended dose.
Development of resistance within a weed species can be avoided or delayed by alternating, sequencing or tank mixing with suitable products having a different mode of action. Some populations of black-grass have been identified as being susceptible to Enhanced Metabolism Resistance (EMR) and control with UNICHEM IPU 500 could therefore be reduced. In these situations additional control measures may need to be considered (e.g. sequences or mixtures with products that have a different mode of action).
When using isoproturon to control black-grass, consider the following guidance:
a. ALWAYS follow available guidelines for preventing and managing herbicide resistant grass and broad-leaved weeds.
b. DO NOT use UNICHEM IPU 500 as the sole means of grass weed or broad-leaved weed control in successive crops.
c. ALWAYS monitor weed control effectiveness and investigate any odd patches of poor grass or broad-leaved weed control. If unexplained, contact your agronomist who may consider a resistance test appropriate.
Consult your agronomist for up to date guidance on chemical and integrated control measures that may be appropriate on a local basis.
A strategy for preventing and managing resistance should be adopted. The Herbicide Resistance Action Committee (HRAC) produces guidelines that may be consulted for additional information.
CROP SPECIFIC INFORMATION
Winter and spring wheat, winter barley, rye and triticale.
Post emergence only in autumn, winter or spring.
Application rate: 3.0 L / product / ha
Apply in the autumn post-emergence of crop until before second node detectable stage of crop growth (GS32). Autumn drilled spring wheat can be treated in the spring.
The residual action of UNICHEM IPU 500 will be reduced on soils with more than 10% organic matter and application on these soils should only be made in the spring.
One treatment per crop.
Early sown crops e.g. September drilled, may be prone to damage if spraying should precede or coincide with a period of rapid growth in the autumn.
Apply in 200 to 400 L of water / Ha
MIXING AND SPRAYING
Pressure: 2-3 bar
Spray quality: MEDIUM
If crop failure occurs for whatever reason following application of UNICHEM IPU 500, an interval of 90 days after autumn application or 30 days after spring application should occur before planting any broad-leaved crop. Deep ploughing should be carried out prior to planting any succeeding crop.
All the requirements or restrictions on the other products labels must be adhered to when tank mixing with UNICHEM IPU 500, which should be added to the tank first when mixing with other products. Continuous agitation must be maintained.
