IMPORTANT 
This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product. 
A herbicide for the control of annual grass and broad-leaved weeds in a wide range of crops.

Restrictions/Warnings
Efficacy
Some soil moisture must be present for MOST MICRO to be activated. Best results will be obtained if rainfall occurs within seven days of application.
Residual control may be reduced:
– Under prolonged dry conditions.
– On soils with a high Kd factor.
– Where organic matter exceeds 6%.
– Where ash content is high.
Do not disturb the soil after MOST MICRO has been applied as this will result in reduced weed control.
Where cultural practices which encourage the build up of organic matter in the soil surface are practiced for a number of seasons the effectiveness of residual herbicides may be reduced. In such circumstances, periodic ploughing is recommended to disperse residues into a greater volume of soil.

Soil types
MOST MICRO may be used on all mineral soil types.
Do not use on soils with more than 10% organic matter.
On stony or gravely soils, crop damage could occur, particularly, if heavy rain follows treatment.
Do not use on water logged soil or soils prone to water logging. 

Seedbed preparation
Trash and straw should be incorporated evenly during seedbed preparation.
Seedbed must have a fine, firm tilth.
Consolidate loose or cloddy seedbeds before use.
Following pre-emergence applications, unconsolidated clods (especially if larger than 7.5cm (3”) diameter) may reduce the level of weed control and cause seed to be inadequately covered, which could result in crop damage

Crop safety
Extreme care must be taken to avoid spray drift onto non-crop plants outside of the target area.
Do not apply MOST MICRO to crops suffering from stress, which may be caused for example by pests, disease, water logging, poor seedbed conditions or previous chemical treatment.
Seed should be covered with a minimum of 3.2cm of settled soil (2.5cm for Sunflowers, 5cm for maize).
Shallow drilled crops should be treated post-emergence.
Do not soil incorporate. Do not spray undersown crops.
Do not undersow crops treated with MOST MICRO.
MOST MICRO should not be used on protected crops, or in greenhouses.

Other Restrictions/Warnings
Before using MOST MICRO on crops to be processed please consult your processor.
Concentrated or diluted MOST MICRO will stain. Avoid spillage.
Staining is minimised or completely removed if skin and clothes are washed immediately.
Hose down machinery immediately after use with a spray tank cleaner.

Resistance management
Strains of some annual grasses (eg Black-grass, wild-oats, and Italian ryegrass) have developed resistance to herbicides, which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
Populations of black-grass and Italian ryegrass with high levels of enhanced metabolism resistance will not be fully controlled.
Key elements of the resistance management strategy for MOST MICRO:
– Always follow WRAG guidelines for preventing and managing herbicide resistant weeds.
– Maximise the use of cultural control measures wherever possible (e.g. crop rotation, ploughing, stale seedbeds, delayed drilling, etc.).
– Use tank mixes or sequences of effective herbicides with different modes of action within individual crops, or successive crops.
– For the control of herbicide resistant grassweeds, always use MOST MICRO in tank mix or sequence with other effective graminicides with different modes of action.
– Apply pre-emergence of weeds wherever possible. If applications are delayed, apply postemergence products/mixtures to small, actively growing weeds, especially where high levels of resistance are suspected and to reduce the risk of resistance development.
– Monitor fields regularly and investigate the reasons for any poor control.

Crop specific information
Winter wheat, durum wheat, winter barley Winter rye, triticale
MOST MICRO applied alone
Product MOST MICRO 
Rate (Litres/ha) 2.7 or 3.6 L/ha 
Water volume 200 L/ha 
Timing Pre-emergence of the crop to before leaf sheath erect stage, (GS30). Do not apply pre-emergence to crops drilled after 30th November. 
Seed depth Seed must be covered with a MINIMUM of 3.2cm of settled soil. ONLY treat shallow drilled crops POST-EMERGENCE

Spring barley
Product MOST MICRO
Rate (Litres/ha) 3.6 L/ha
Water volume 200 L/ha
Timing Pre-emergence of the crop. Apply MOST MICRO as soon as possible after drilling and before emergence. Due to risk of dry soils, do not apply MOST MICRO alone after the end of March unless rainfall is imminent.
Seed depth Seed must be covered with a MINIMUM of 3.2cm of settled soil.

Potatoes (First early, second early and maincrops)

MOST MICRO applied in tank mix with Metribuzin
Product MOST MICRO + Metribuzin 
Rate (Litres/ha) 3.6 L/ha + 350g/ha In dry conditions apply a MOST MICRO – Metribuzin sequence. 
Water volume 200 L/ha 
Timing Pre-emergence of the crop. Apply as soon as possible after planting and final ridging up. Loose structured ridges must be allowed time for settlement before application. Do not apply later than 7 days before emergence. 
Soil types Do not use on Sands (S), Gravelly or Stony soils. 
Variety Read the Metribuzin label carefully, particularly with regard to varietal restrictions. 
Application MOST MICRO should be applied in a minimum of 200 litres of water/ha. 
Notes Best weed control will be achieved with settled well-rounded ridges with few clods. If re-ridging is necessary, delay application until after the final ridging is completed. Slight distortion and discolouration of the initial shoots may occur if very heavy rain falls after application but before emergence, particularly to crops grown on very light soils. This is quickly outgrown and subsequent growth is unaffected. Read the Metribuzin label carefully, particularly with regard to following SPECIMEN crop restrictions

Sunflowers
Product MOST MICRO Rate (Litres/ha) 3.6 L/ha 
Water volume 200 L/ha 
Timing Apply as soon as possible after sowing and final seedbed cultivation, before crop and weed emergence. 
Seedbed Consolidate seedbeds after drilling to provide a firm level soil. Seed should be drilled so that after seedbed consolidation it is covered by a minimum of 2.5cm of settled soil.

Product MOST MICRO 
Rate (Litres/ha) 4.1 L/ha Water volume 200 L/ha 
Timing Pre-emergence to before 4th leaf of the crop. 
Notes Do not use on sweetcorn or maize grown for seed. Seed must be covered by a minimum of 5cm of settled soil. The use of MOST MICRO may affect the full development of crown roots which function only to anchor the plant. This has no effect on the yield of maize. If application is followed by a period of dry conditions or in situations where very heavy populations occur, a sequence of MOST MICRO and a product applied post-emergence may be necessary

Following Crops
Following crops after normal harvest
Before ryegrass is drilled after a very dry season, plough or cultivate to at least 15cm. If spring crops are to be followed by crops other than cereals plough or cultivate to at least 15cm.

In the event of crop failure
In the event of crop failure the land must be ploughed or thoroughly cultivated to a minimum depth of 15cm to ensure any residues are evenly dispersed throughout the soil. 

Mixing and application 
Following crops after normal harvest
Never prepare more spray solution than is required. Half fill the tank with clean water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of MOST MICRO to the spray tank while re-circulating. Fill up the tank with water and continue agitation until spraying is completed.
When tank mixes are to be used, take due note of any instructions given as to the order of mixing. Each product should be added separately to the spray tank and fully dispersed before the addition of any further product(s).
On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely

Application
MOST MICRO can be used in tractor mounted/trailed sprayer and knapsacks. Ensure good, even spray cover of the target using a FINE or MEDIUM quality spray, as defined by BCPC.

Boom sprayers 
Apply MOST MICRO in 100-200 L/ha.
When tank mixing with other products use a minimum water volume of 200 L/ha depending on the tank mix partner. 
For potatoes apply MOST MICRO in minimum 200 L/ha.

Knapsack sprayers
Use a maximum of 16 mls of MOST MICRO per litre of water and ensure a good, fine coverage of the target.

Sprayer cleaning 
After spraying, thoroughly clean and flush out application machinery with a minimum of three rinses, to ensure that all traces of product are removed to avoid sticking of dried material to spray tank walls or spray lines, etc.

Tank Mixtures
When tank-mixing ONLY APPLY within label conditions for each product. For up-to-date details of compatible tank-mixes, contact your supplier or local Sipcam representative.

Sequential treatments
MOST MICRO may be used in sequence with any other approved product. Leave a minimum interval of 24 hours unless longer is specified on the label. MOST MICRO may be applied in sequence with Avadex provided only one product is applied pre-emergence of the crop.
