Cereals Winter wheat, barley and oats: Spray in the spring from the leaf sheath erect stage until before the first node is detectable. Do not apply in the autumn, winter during frosty weather or if frosts are expected following application. Spring wheat and barley: Spraying can take place from the five leaf stage until before the first node is detectable. Application may be made from the three leaf stage if the lower rate of 1.4 l/ha is used. Caution: Application under very hot conditions at later timings can cause ear damage if the crop comes under stress at or after application. Barley is particularly subject to malformation and particular attention must be paid to the correct growth stage if the crop is intended for malting. Spring oats: Spray from 1st leaf stage until before first node is detectable. Undersown cereals: Spray when Red Clover has at least 2 trifoliate leaves and the grasses have at least 4 leaves and begun to tiller. The weeds should be dense enough to cover the clover seedlings. Some damage to red clover must be expected, but this will normally be out-grown. Do not apply if white clover is present. Cereals undersown with grass: Application should be made when the grasses have begun to tiller, and the cereal crop is at the correct growth stage, as listed above.

DO NOT apply during drought or rain or if rain is expected. DO NOT roll or harrow within a week of spraying. DO NOT apply before undersowing. Do NOT apply to crops suffering from stress as a result of frost or drought.

For best results in cereals spray when both cereals and weeds are growing well and weeds are at cotyledon stage.

Weed Control in Cereals HY-MCPA controls a broad range of annual and perennial weeds. See the product label for individual weed details.

Volunteer Oilseed Rape HY-MCPA controls a broad range of annual and perennial weeds. See the product label for individual weed details.

Grassland HY-MCPA may be used on Established Grassland (permanent grassland), Young Grass Leys and Grass Seed Crops (rotational grass). The time of application is best determined according to the growth stage of weeds present. A maximum of 2 applications per year are permitted. Any clovers present in the sward will receive a check but should recover. Top dressing ten days before treatment is recommended to assist kill of weeds and subsequent recovery of the sward.

Young Grass Leys At a rate of 1.4 l/ha HY-MCPA will control annual weeds listed under the section on cereals. Spray when the grasses have at least four leaves and have begun to tiller. Where several species of grass are present the timing should be dictated by the slowest developing species.

Grass Seed Crops Spray when the grasses have at least four leaves and have begun to tiller, but at least five weeks before heading.

Weeds Controlled in Grassland HY-MCPA will control annual weeds as listed under the section on cereals. See product label for individual weed control. Annual weeds will be best controlled if spraying is done while the majority of weeds are seedlings. Perennial weeds should be sprayed during their period of maximum growth, usually when the flower buds are beginning to form. The response of perennial weeds to treatment is often variable with only the aerial parts killed, though often suppression will occur. The recovery of weeds will be reduced if the grass is growing vigorously at the time of treatment.

Managed Amenity Turf and Lawns Treatments should be made in the spring or summer when growing conditions are good. An interval of 4 to 6 weeks should elapse between sprays if subsequent treatments are needed. Restrictions - Do not mow 2 days before or 1 day after spraying. Do not apply to grass suffering from stress as a result of frost or drought. Do not use on new turf for 6 months after establishment. The first 4 mowings must be composted for 6 months before use.

Recommended Tank Mixtures for Turfs and Lawns Control of certain weeds in turfs and lawns, not normally controlled by HY-MCPA alone such as clover and yarrow can be achieved by using a tank mixture of HY-MCPA plus Optica. Also the control of other species such as chickweed and daisies will be improved by using this mixture. HY-MCPA at 1.4-2.7 litres per hectare with Optica at 2.4 litres per hectare in a volume of 560 litres per hectare, provided the mixture is used immediately. Applications will achieve best results if sprayed in summer, once the clovers are completely emerged. For complete list of species controlled see the product label.

Weed control of Managed Amenity Turf and Lawns HY-MCPA controls a broad range of annual and perennial weeds. See the product label for individual weed details.

Linseed HY-MCPA may be used on all commercially grown varieties of linseed. Application should be made as soon as the crop is 5cm in height but before it reaches 15 cm high. Temporary wilting may occur but no long terms effects will be noticed. However, do not apply when the linseed is under stress from high temperatures or drought. Restrictions - Do not apply to crops suffering from stress as a result of frost or drought. Do not apply during drought, rain or if rain is expected. For full details of weed control see the product label.

Verges and Industrial Sites HY-MCPA may be used on roadside verges, industrial land and land not intended for cropping. Treatments should be made in the spring or summer when growing conditions are good. An interval of 4 to 6 weeks should elapse between sprays if subsequent treatments are needed. Restrictions - Do not mow 2 days before or 1 day after spraying. Do not apply to grass suffering from stress as a result of frost or drought. Do not use on new turf for 6 months after establishment. The first 4 mowings must be composted for 6 months before use.
