DIRECTIONS FOR USE
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.
 
Restrictions or Warnings
Do not apply MONITOR to winter wheat crops previously treated with any other sulphonylurea herbicide such as Quantum, Ally, Harmony M,Lexus, or Eagle. Do not apply any of these products in winter wheat crops treated with MONITOR, either as a tank-mixture or subsequently.
MONITOR should not be applied to winter wheat under-sown with grass,clover or other legumes, or any other broad-leaved crops. MONITOR should only be used where damaging populations of competitive weeds have emerged. In the absence of these populations MONITOR may cause some yield reduction.
Do not use straw from treated crops as a mulch for anyother crop.
Take care to avoid drift onto crops and other plants outside the target area.
Failure to thoroughly clean the sprayer after use can result in damage to sensitive crops during subsequent use of the equipment. Follow washout and cleaning instructions carefully.
 
Weeds controlled
MONITOR is recommended for use as a spring post-emergence treatment in all cultivars of winter wheat and will check the growth of Couch, reducing its competitive effect. MONITOR can give good control of a range of Brome grasses, including Soft,Meadow,Rye and Barren Brome when applied up to the
specified growth stages, with a check to growth once the most susceptible growth stages have been exceeded. Cleavers are also controlled when applied at susceptible growth stages, later applications may result in a check to growth of Cleavers and require additional treatments for complete control.
Broad -leaved weeds controlled include Mayweed and Chickweed.
The addition of a recommended surfactant is essential for good results. MONITOR should only be used where damaging populations of these competitive weeds have emerged. In the absence of such populations  MONITOR can reduce yield.
 
Climate
The best results from MONITOR are from treatments made when annual weeds are small and grow ing actively, in the early spring. Control of Common Couch may be reduced if treatment is made when this weed is small, e.g. two leaves or fewer emerged. Dry weather conditions for any extended period before or after application may result in reduced weed control.
Avoid application of MONITOR to crops under stress or in climatic conditions that cause dormancy in the weeds; these include severe drought, water-logging, frost and strong, cold winds.
 
Application rates and weed stages
APPLICATION TIMING:
Apply post-emergence of the crop only in the spring (after February 1st), from the three expanded true leaf stage (G.S. 13) onwards up to flag leaf ligule just visible (G.S. 39), provided the recommended weed stages have not been exceeded.
Dose Rate: 25 g/hectare
PLUS Additional recommended surfactant : Frigate/Newman’s T80 0.2% v/v of spray volume
 
Resistance
This product contains sulfosulfuron which is an ALS inhibitor, also classified by the Herbicide Resistance Action Committee as ‘Group B’ Use only as part of a resistance management strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grass-weed control. Strains of some annual grasses (e.g. Black-grass, Wild oats and Italian Ryegrass) and broad-leaved weeds (e.g. Chickweed and Poppy) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing herbicide resistant grass weeds should be adopted. Guidelines have been produced by the Weed Resistance Action Group. Copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer (Monsanto). Applications of Monitor must form part of an integrated weed and resistance management strategy.
This should include the following measures:
1. Rotational use of herbicides with differing modes of action.
2. The use of Monitor in sequence with other products with different modes of action that are active against the same target.
3. Cultural control methods to reduce herbicide selection pressure.
 
Crop specific information
MONITOR can be used on all varieties of winter wheat (excluding Durum wheat).
 
Following crops
SUBSEQUENT AUTUMN AND SPRING CROPPING IN NORMAL ROTATION
Subsequent autumn cropping:
Crops of winter wheat, winter oilseed rape and winter field beans may be drilled in the autumn after application of MONITOR on any soil type. Crops of winter barley may be planted in the autumn after application of MONITOR on s oil types with less than 60% sand in their composition i.e. NOT on sands, loamys and sandy loams, sandy clay loams and sandy clays. Drilling winter barley in these soil types after application of MONITOR could result in yellowing and stunting of the crop , with possible reductions in yield.
Subsequent spring cropping:
Crops of spring wheat, spring barley, spring peas and spring beans, spring oil seed rape and potatoes may be drilled as subsequent spring crops following application of MONITOR.
Sugar beet or any other following crop not stated above must not be drilled until the second spring following an application of MONITOR.
 
Mixing and spraying
Equipment
Apply MONITOR through a hydraulic sprayer
Preparation for Use
MONITOR quantity required should be carefully measured in the container supplied. Use the measuring container to measure out 25g of product equivalent to the dose for one hectare. Any remaining herbicide should be resealed in the initial container and stored in a dry place. Add clean water to the spray tank until half-full: add the required amount of MONITOR, wash and rinse the container thoroughly when empty, adding the washings to the spray tank, then add the required amount of additional surfactant (see Compatibility section), and top up with water to the required level.
Agitate the spray liquid continuously before spraying. Apply immediately.
Volume
Apply in a volume rate of 200-250 litres/hectare as a MEDIUM spray (BCPC category).
Good, even spray coverage of weeds is essential. Ensure that sprayed swaths do not overlap.
 
Spray tank cleaning
TO AVOID SUBSEQUENT DAMAGE TO CROPS OTHER THAN WINTER WHEAT, THOROUGHLY CLEAN ALL SPRAY EQUIPMENT IMMEDIATELY AFTER SPRAYING MONITOR, INCLUDING INSIDE AND OUTSIDE OF LID, USING ALL CLEAR EXTRA SPRAYER CLEANER ACCORDING TO THE LABEL INSTRUCTIONS. ALTERNATIVELY USE THE FOLLOWING PROCEDURE:
1. Immediately after spraying, drain tank completely. Any contamination on the outside of the spraying equipment should be removed by washing with clean water.
2. Rinse inside of tank with clean water and flush through booms and hoses using at least one-tenth of the spray tank volume. Drain tank completely.
3. Half fill tank with clean water and add 1/3 litre household ammonia (contains 9.5% ammonia) for each 100 litres of tank volume. (Equivalent amounts of alternate strength ammonia solutions can be used providing the final concentration in the full tank is 0.03%). Agitate and then flush the boom and hoses with the cleaning solution. Top up with water making sure the tank is completely full and allow to stand for 15 minutes with agitation. Again flush the boom and hoses and drain tank completely.
4. Nozzles and filters should be removed and cleaned separately with ammonia solution at the same concentration as used in the sprayer.
5. Rinse the tank with clean water and flush through the boom and hoses using at least one-tenth of the spray tank volume. Drain tank completely.
6. For the disposal of washings, follow the DEFRA/HSC/NAW publication “Code of Practice for using Plant Protection Products” of January 2006. Do not spray onto sensitive crop or land intended for cropping with sensitive crop.
NOTE: If it is not possible to drain the tank completely, step 3 must be repeated before going on to step 4.
