Copper Deficiency Symptoms in Crops

Copper deficiency shows first on new young leaves. Spray Copper EDTA 12% immediately on seeing these signs:

New leaves pale yellow and curled copper is needed for enzyme activity and chlorophyll production
Stems weak and bending copper supports cell wall lignification and stem strength
Fewer flowers and fruits copper is essential for pollen viability and seed formation
Poor grain filling in cereals wheat and paddy ears remain empty or partially filled
Stunted plant growth severe deficiency stops overall plant development
Pale blue-green colour absent healthy copper levels give leaves a deep green colour

Dose and Application Rate

Method	Dose	Timing	Crops
Foliar Spray	0.5–1 g / litre water	On deficiency symptoms or during vegetative stage	All crops
Drip Irrigation	300–500 g / acre	Vegetative to flowering stage	Vegetables, fruits, horticulture
Soil Application	500 g / acre	Basal dose — before sowing or transplanting	All field crops
Soil + FYM Mix	500 g + 10 kg FYM / acre	During field preparation	Field crops and vegetables

Note: Doses above are for reference. Always confirm the exact dose from the product label. Adjust based on soil test results and crop stage.

How to Use Copper EDTA 12%

For Foliar Spray:

Dissolve 0.5–1 g in 1 litre of clean water. Mix well until fully dissolved.
Spray in the early morning or late evening avoid strong afternoon sun.
Cover both upper and lower leaf surfaces for best absorption.
Repeat after 14–21 days if deficiency symptoms persist.

For Drip Irrigation:

Dissolve 300–500 g per acre in water. Ensure no undissolved particles remain.
Inject through the drip system during the regular irrigation cycle.
Flush the drip lines with plain water after application.

Jar Test Before Tank Mixing: Before mixing with any pesticide or fertiliser, add a small amount of each to a jar with water. Wait 30 minutes. If no precipitation or separation occurs, tank mixing is safe.

Frequently Asked Questions (FAQs)

What is the dose of Copper EDTA 12%?

Foliar spray: 0.5–1 g per litre of water. Drip irrigation: 300–500 g per acre. Soil application: 500 g per acre mixed with 10 kg FYM. Always confirm dose from the product label.

What is the difference between Copper EDTA and Copper Sulphate?

Copper EDTA is chelated — it stays plant-available at all soil pH levels and absorbs instantly. Copper Sulphate precipitates in alkaline soils (pH above 7) and can cause leaf burn in foliar spray. Copper EDTA is 3–5× more efficient at a lower dose.

What are the symptoms of copper deficiency in crops?

New leaves turn pale yellow and curl. Stems become weak and bend easily. Flowers and fruit numbers drop. In wheat and paddy, grains do not fill properly and ears remain empty. Plant growth slows in severe cases.

When should I spray Copper EDTA 12%?

Spray preventively during the vegetative stage, or immediately when deficiency symptoms appear. Always spray in the early morning or late evening. Avoid spraying in strong afternoon sunlight to prevent evaporation and leaf stress.

Can Copper EDTA 12% be mixed with other fertilizers or pesticides?

Yes, it is compatible with most water-soluble fertilizers and pesticides. Always do a jar test before tank-mixing with any new product — mix a small quantity and wait 30 minutes to check for precipitation or separation before full-scale mixing.

On which crops can Copper EDTA 12% be used?

All crops — wheat, paddy, maize, soybean, cotton, chilli, tomato, brinjal, potato, grapes, mango, pomegranate, banana, citrus, onion, garlic, and all other vegetables, cereals, pulses, and fruit crops.
