Headland In-organic Copper is used to correct copper deficiency in a wide range of agricultural and horticultural crops. Copper is essential to crops for stimulation of enzyme systems in association with other elements and is particularly active in many of the metabolic pathways within the cell. All crops can be affected by copper deficiency including cereals, vegetables, fruit, brassicas, root crops, horticultural crops and grassland. Crops grown on peasty soils, shallow organic chalks, heathland and heavily leached soils are most likely to exhibit copper deficiency.
Liquid Copper lost it's approval for use as a fungicide and it can now only be used to correct copper deficiencies. However, copper has proven very successful in reducing the development of Box Blight & other diseases when used in conjunction with Signum.
For reference purposes, copper was used for the following diseases (application rates are shown in the application rates tab):
- Apples and Pears – Canker
- Blackberries – Purple Blotch Disease
- Blackcurrants – Rust
- Celery – Celery Leaf Spot
- Cherry – Bacterial Canker
- Hops – Downy Mildew
- Potato – Potato Blight
- Tomato – Blight and Buckeye Rot
- Wine grapes and table grapes – Downy Mildew
- Corrects copper deficiencies in agricultural and horticultural crops.
- Has the ability to reduce development of diseases such as box blight when used with Signum.
- Physically compatible with many spray applied agricultutal chemicals.
- Always read the product label before use.
- Shake the container thoroughly before opening and use.
- Do not allow the mixture to stand in the tank without agitation.
- To combat diseases such as downey mildew and box blight take a look at Amistar.
- Save time and money and mix with Blue Dye to ensure no areas are missed or overdosed.
- Always wear protective clothing, such as Chemical Resistant Gloves, when handling Headland Liquid Copper.

Marginal deficiency: 0.25 l/ha in at least 200 l/ha water
Moderate deficiency: 0.5 l/ha in at least 200 l/ha water
Severe deficiency: 0.5 l/ha in at least 200 l/ha water.
Repeat after 3 - 4 weeks and again if symptoms return.
Applications should be made during periods of active growth when there is enough foliage present to absorb the spray. Do not apply before the 3-leaf stage. Do not apply when the crop is under stress due to drought or extremes of temperature. Crops grown on peaty soils, shallow organic chalks, heathland and heavily leached soils are most likely to exhibit copper deficiency.

Liquid Copper lost its approval for use as a fungicide however for reference purposes, copper was used for the following diseases at the below application rates:
Apples and Pears – Canker
Use 10 litres/ha in 1000 litres of water. Apply immediately prior to leaf fall. Repeat at 50% leaf fall and again at bud break if necessary. Do not apply more than 3 sprays per. crop.
Blackberries – Purple Blotch Disease
Use 0.5 – 1.0 litres/ha in 1000 litres of water depending on disease severity. Apply during mid-May and repeat twice at 10-day intervals. Do not apply more than 3 sprays per crop.
Blackcurrants – Rust
Use 6 -10 litres/ha in 1000 litres of water depending on the severity of the disease. Apply to affected bushes after harvest.
Celery – Celery Leaf Spot
Use 7 - 10 litres/ha in 700-1000 litres of water. Spray at the seedling stage and when planting out. Repeat at 10 - 14 day intervals as required.
Cherry – Bacterial Canker
Use 6 litres/ha in 1000 litres of water. Apply 3 sprays at 3 week intervals, beginning in mid-August. Some varieties may show symptoms of phytotoxicity.
Hops – Downy Mildew
Use 4 litres per 1000 litres of water as a high volume spray. Spray at 10 - 14 day intervals from mid-June until 7 days before harvest. Remove all infected terminal, lateral and basal spikes. This treatment will also reduce the development of powdery mildew.
Potato – Potato Blight
Use 10 litres/ha in 1000 litres of water. Increase the water volume to 1300 litres during July and August. Apply immediately after a blight warning before onset of disease, followed by further sprays from mid-June to mid-August at 10 -14 day intervals.
Tomato – Blight and Buckeye Rot
Use 6 litres/ha in 1000 litres of water. Apply before onset of the disease and repeat at 10 - 14 day intervals throughout the season. For control of Buckeye rot, also spray the lower parts of the plant and the soil.
Wine grapes and table grapes – Downy Mildew
Use 10 litres/ha in 1000 litres of water. Apply at bud burst and repeat at 10 - 14 day intervals as necessary.
- Avoid spraying in the heat of the day, of if rain is forecast for 12 hours after application
