COMPITOX PLUS is a hormone herbicide which is absorbed by both shoots and roots and rapidly translocated within herbaceous plants.

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 propogate and may become dominating. A weed species is considered to be resistant to a herbicide if it survives a correctly-applied treatment at the recommended dose. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. 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.

 

Spring cereals and grass seed crops may only be treated once per crop.

DO NOT apply COMPITOX PLUS to any crop suffering from herbicide damage or physical stress.

DO NOT apply COMPITOX PLUS during cold weather, periods of drought, if rain or frost are expected, nor if the crop is wet.

If sharp or severe frosts occur within three to four weeks of application to barley under stress or of low vigour on light soils, scorch or stunting may occur and yields may be less than optimum.

The crop should not be rolled or harrowed within a period of seven days before or after spraying with COMPITOX PLUS.

Avoid drift onto all broad-leaved plants outside the target area.

WASH EQUIPMENT thoroughly immediately after use. Rinse with water three times, drain and allow to dry. Traces of herbicide left in the sprayer may damage susceptible crops if these are subsequently sprayed using the same equipement.

 

The best weed control will be achieved if crops are sprayed in conditions when weeds are actively growing, provided the crop is within the correct growth stages.

Identify the weeds present and select the appropriate rate as listed below. Optimum conditions prevail when ALL the following are true:

1. Soils are warm and moist.

2. Weeds have not been frost-hardened.

3. Warm, moist conditions are expected to persist for several days after application.

This is particularly important when COMPITOX PLUS is used in the spring to control large autumn germinated cleavers, which may have become winter hardened.

Provided weeds are cotyledon to two leaves and application conditions meet the requirements listed above, susceptible species will be controlled at the rates recommended below.

If weeds are three to six leaves or conditions are less than optimum, using a higher rate will still control susceptible species. For optimum suppression of perennial weeds and species classed as moderately susceptible, apply COMPITOX PLUS at 2.3 l/ha.

 

2.3 l/ha.

COMPITOX PLUS may be applied from the leaf sheath erect stage up to before third node detectable stage in the spring. If sharp or severe frosts occur within three to four weeks of application to barley under stress or of low vigour on light soils, scorch or stunting may occur and yields may be less than optimum.

1.5 to 2.3 l/ha dependant on the target weed species. The 2.3 l/ha rate may only be used once the crop has reached leaf sheath erect stage.

One application of COMPITOX PLUS can be made from the first fully expanded leaf stage until before the first node is detectable (GS 31).

2.4 l/ha.

The sward should not be topped for at least a week before or after spraying. A maximum of two applications per year are permitted.

 

Allow to flower in July and then cut the flower stalks before seeding to weaken root reserves. Wait two weeks and then apply the recommended rate of COMPITOX PLUS. Docks will be severely checked but may recover, in which case the treatment should be repeated in the following season.

 

Treat when actively growing and not shielded by grass, usually late summer or autumn.

If appreciable foliage is present there will be top growth suppression of weeds listed as top growth suppressed (SP) in the weed susceptibility table. When using a conventional sprayer apply in 185–330 litres of water per hectare.

When applying through a knapsack sprayer use a minimum of 480 litres of water per hectare.

 

1.5 to 2.5 l/ha.

One application can be made once grasses have at least three fully expanded leaves and have begun to tiller, but at least five weeks before the emergence of the seed head in grass seed crops. Treat Common chickweed when growing actively and not shielded by grass, usually late summer or autumn. Any clover present will be severely damaged.

Apply in 185–330 litres of water per hectare.

 

When using a conventional hydraulic sprayer apply 1.5 to 2.4 litres COMPITOX PLUS in 185–400 litres of water per hectare. Use the higher volume on larger weeds or where weeds or crop are dense. When applying through a knapsack sprayer use a minimum of 480 litres of water per hectare.

Two applications of COMPITOX PLUS can be made to managed amenity turf. For spring and summer sown turf, apply approximately two months after sowing. Turf sown or laid later in the year should not be treated until the following spring. For established turf, apply COMPITOX PLUS during the growing season which is normally April to September.

CAUTION: Do not apply to newly laid turf until it is well established and actively growing. Do not apply to turf under stress, particularly in periods of drought.

 

Apply as a MEDIUM spray as defined by BCPC.

The spray volume for COMPITOX PLUS alone or in mixtures is 185–330 litres of water per hectare. The lowest volume should only be used in open crops where weeds are small and where recommendations for any tank mix partner allow. As weeds become larger and/or crop cover increases, then the water volume should be increased.

This is particularly important with cleavers. Once cleavers are beyond the two whorl stage up to six whorls, a water volume of 330 litres per hectare is required to ensure good coverage and control.

 

Half fill the spray tank with clean water and start the agitation. Pour in the required amount of COMPITOX PLUS. Add the remainder of the water and continue agitation until spraying is completed.

When tank mixes are to be used, each product should be added separately to the spray tank, taking due note of any instructions given as to the order of mixing
