A maximum total dose of 2.6kg chloridazon/ha may be applied every third year on the same field. The maximum concentration must not exceed 3 litres of product per 100 litres of water.

 

VOLCAN COMBI has residual action, which controls germinating weeds during or shortly after emergence.

VOLCAN COMBI FL is less dependent on soil moisture than many other residual herbicides, however best results will be obtained from application to a moist seed bed. Adequate soil moisture or irrigation or rainfall soon after application is essential for best results.

Applications should be made to a fine, firm, level seedbed. VOLCAN COMBI FL is suitable for mineral and organic soils with less than 5% organic matter.

If very light soils have a high proportion of stones, growers should consult their Sipcam Agriculture representatives.

All varieties of sugar beet may be treated with VOLCAN COMBI FL.

 

Effective weed control in sugar beet crops is best achieved through a sequential programme of sprays. The use of pre-emergence treatments improves overall weed control within the spray programme and increases the flexibility for timing of post-emergence herbicide treatments.

Application of VOLCAN COMBI FL pre-emergence of the crop will improve the efficacy of the post emergence programme particularly where post-emergence sprays may be delayed, for example by adverse weather.

Apply VOLCAN COMBI FL at a rate of 3 l/ha.

Pre-emergence application should be made as part of a sugar beet spray programme and followed by an appropriate post-emergence spray programme as further flushes of weeds appear.

 

 

Apply VOLCAN COMBI FL overall in 200 litres water per hectare using a FINE spray (BCPC classification).

For pre-emergence use on sugar and fodder beet, the maximum concentration must not exceed 3 litres product per 100 litres of water.

 

Clean the sprayer, spray bars and nozzles to ensure that there are no traces of the previous products. This is most important after hormone and sulfonyl urea weedkillers.

Check that nozzle tips are clean, undamaged, of the required type to give the correct spray quality spray, and are all of the same size, giving equal outputs and distribution.

Add a small quantity of clean water to the tank, just sufficient to cover the inlet to the pump.

Check that agitation is operating correctly. Add the necessary quantity of VOLCAN COMBI FL to the water in the sprayer, whilst the agitator is operating. Mix only sufficient chemical for immediate use. Add water to the required level. Continue agitation until the tank load is used.

Ensure that the spray nozzles are set at the correct height to give even spray cover.

Commence spraying, being careful to maintain correct pressure and tractor speed.

Avoid overdosing or drift onto neighbouring crops.

Following use of VOLCAN COMBI FL spray equipment should be thoroughly cleaned.

There are no specific requirements for cleaning following use of VOLCAN COMBI FL.

Growers should consult manufacturer’s guidance for procedures for their specific equipment, and use a combination of triple rinsing and agitation with clean water.

Equipment Washings should be disposed of safely following the Code of Practice for Using Plant Protection Products and relevant Environment Agency guidance.

 

Consult the HSE publication “Code of Practice for the safe Using Plant Protection Products.

 

When used as recommended VOLCAN COMBI FL exhibits great safety to beet, combined with dependable weed control. However, the beet plant is very sensitive to herbicide treatments, especially if under stress from other factors, for example; previously applied pesticides and herbicides, soft-growth after prolonged rain, sudden changes in temperature, high light intensity, high radiant temperatures at time of application, prolonged low temperature periods, the use of certain soil insecticides particularly on sandy soils, damage by wind blows, nutrient deficiencies such as manganese, and other stress factors, including insect and fungal attack.

Under these conditions crop tolerance to VOLCAN COMBI FL may be reduced, particularly when used in conjunction with other herbicides, either as tank mixes or sequentially.

 

As with other beet herbicides, crops sprayed pre-emergence with VOLCAN COMBI FL and subsequently subjected to frost may be checked such that they may not fully recover.

 

Only sugar beet or mangels should be sown within 4 months of the last application of VOLCAN COMBI FL. Winter cereals may be sown 16 weeks after the last application of VOLCAN COMBI FL. Mouldboard ploughing to a depth of 15cm followed by thorough cultivation is recommended before planting any crop.

 

Avoid overspray or spray drift onto plants outside the target area particularly in hedgerows and field margins

 

Annual grasses and broad leaved weeds can develop 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 UK-Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.

Protect from frost

Shake well before use

Extreme care must be taken to avoid spray drift onto non-target plants outside the target area.
