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.
Copper has proved very successful in reducing the development of Box blight & other diseases when use din conjunction with Signum
|Recommended Dilution Rates|
|Rate Per Hectare||Dilution Per Litre||Water Rate per Hecatare|
|0.5 Litre||2ml per litre of water||
For diseases such as Downey Mildew, Black Rot & Box Blight we suggest looking at Amistar 5L or Bumper 250. To help increase the penetration & disease control by up to 20%, mix in with Evoque Fungicide Improver
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, it can now only be used to correct Copper deficiencies. For reference, copper was used for the following diseases.
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- If you are trying to control Powdery Mildew then look at Nimrod 1L
- For other diseases such as Alternaria, Rust, Downey Mildew & Ring Spot look at Amistar 5L
