Active Ingredient(s): 60g/L clomazone and 233g/L metribuzin 
Formulation: ZC formulation 
Pack Size: 5 L 

 

Other specific restrictions:

This product qualifies for inclusion within the Local Environment Risk Assessment for Pesticides (LERAP) scheme. The statutory buffer zone must be maintained and the distance recorded in the LERAP record form. The LERAP record form must be kept available for three years. This product must not be applied via hand-held equipment.

 

Some transient crop bleaching may occur under certain climatic conditions and can be severe where heavy rainfall follows application. This transient crop effect is rapidly outgrown and has no effect on crop yield.

Do not use on soils that are compacted or of a poor structure which may then be liable to water logging.

Reduced levels of weed control may occur if application is made to dry cloddy seedbeds or if a prolonged dry period follows application.

Do not overlap spray swaths.

The safety of METRIC to daughter tubers has not been tested; consult the manufacturer or your advisor before using on seed crops.

There is a risk to adjacent crops and non-crop vegetation from the volatilisation of clomazone. This may result in damage/bleaching to neighbouring vegetation. If effects are seen, they must be reported via the stewardship program. Please call Belchim Crop Protection for regional support at 01480 403333.

 

As part of Good Agricultural Practice, steps should be taken to adopt a resistance management strategy as standard. METRIC should be alternated or mixed with herbicides with a different mode of action and similar spectrum of activity. Any subsequent herbicide applications should be made using herbicides with a different mode of action. Other measures relevant for prevention of the risks of resistance are: deep ploughing, mechanical weed control, preventing dispersion of weed seeds and soils between different sites and cultivation of competitive crop cultivars.

Strains of some annual grasses e.g. 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 advisor or product manufacturer.

 

 

METRIC is a residual herbicide which can be used on different varieties of potatoes. The following maincrop and early potato varieties* may be treated pre-emergence:

First Earlies:Alcmaria; Arran Comet;Maris Bard; Ostara; Pentland Javelin; Ulster Sceptre.

Second Earlies:Ausonia; Estima; Marfona; Maris Peer; Nadine; Wilja.

 

Cara; Kingston; Pentland Squire; Desiree; Pentland Crown; Record; Kind Edward; Pentland Dell; Romano.

 

The following weeds are susceptible to METRIC, when applied pre-emergence of the weeds to a moist, firm seedbed free from clods:

 

METRIC must be applied pre-emergence of the crop and target weeds, following the last ridging and before ridge cracking (i.e. approximately 7 days before expected potato emergence). Crop plants emerged at the time of application may be severely damaged. Extreme care must be taken to avoid drift on to non-target plants outside of the target area; particularly sensitive crops include lettuce, sugar beet and brassicas.

 

Apply METRIC at a dose of 1.2 L/ha. Maximum number of treatments:one per crop and no more than one per year. Consult processor before using on crops for processing.

 

Apply in 200 to 400 L of water per ha as a COARSE spray (as defined by BCPC). SOIL TYPE Do not use METRIC on the textural group of soils known as 'Sands' or 'Very light' soils (ADAS 85 classification). Do not use on soils with more than 10% organic matter.

 

For crop safety cover the seed potato with a minimum of 20 mm of soil. For optimum efficacy, the seedbed should be firm, level and free of clods. Loose and puffy seedbeds should be consolidated before spraying.

 

Before drilling or planting any succeeding crop, soil MUST be mouldboard ploughed to a depth of at least 15 cm (6”) taking care to ensure that the furrow slice is inverted. Ploughing should be carried out as soon as possible (preferably within 3-4 weeks) after lifting the potato crop, but certainly no later than the end of December. In the same year

Provided at least 16 weeks have elapsed after the application of the recommended rate of METRIC, cereals and winter beans may be grown as following crops.

Do not grow any vegetable brassica crop (including cauliflower, calabrese, Brussels sprout and cabbage), lettuce or radish on land treated with METRIC in the previous year. Cereals, oilseed rape, field beans, combining peas, potatoes, maize, turnip, linseed and sugar beet may be sown from spring onwards in the year following METRIC use.

 

Following crop failure and after soil cultivation only winter beans may be sown. Provided that at least 16 weeks have elapsed after METRIC application winter beans may be sown or planted. For all replacement crops, soil should be ploughed and cultivated to a minimum depth of 25 cm.

 

Before using METRIC ensure that the spraying equipment is clean.

1. Half fill the tank with clean water and commence agitation. Add the required dose to the spray tank and complete filling, continuing agitation until spraying is completed.

2. On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times when empty. Add washings to the sprayer at time of filling and dispose of container safely.

3. Use immediately. Do not leave spray solution standing in the tank.

If using an induction system then mixing should be as follows:

1. Half fill the induction bowl with clean water.

2. Slowly pour the required amount of product into the induction bowl, turn on the pump and suck the contents of the induction bowl into the spray tank, at the same time rinsing the bowl.

3. On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times when empty. Add washings to the sprayer at time of filling and dispose of container safely.

4. Repeat the procedure of half filling the bowl with water and sucking out until no trace of product remains on the mesh, filter, drain hole or sides of the bowl.

5. Ensure all contents are sucked out and the bowl is thoroughly rinsed before adding any tank-mix partner.

6. Use immediately. Do not leave spray solution standing in the tank.

 

All application equipment and contaminated clothing should be thoroughly washed/cleaned with water diluted detergent solution, and rinsed with clean water three times. After each step of washing drain the sprayer, spray out completely. Ensure that all liquid is removed from the sprayer tank, pump and hoses.

Remove nozzles, open tank and drain pump to allow free access of air to all parts of the system.

Care should be taken not to rinse contaminated washings from application equipment into waste water channels. Contaminated cleaning liquids should be disposed of safely according to, local regulations.

Operators should read the sprayer manufacturer’s instructions before beginning to wash out sprayers.
