How it works / Technical advantages
COBBER G contains the copper ion (Cu²⁺) complexed by gluconic acid. According to the datasheet, this organic complexation favors copper transport within the plant and contributes to high assimilation.
Its systemic action is associated with stimulation of phytoalexin synthesis, compounds linked in the datasheet to increased natural crop defenses. The product is also described as biodegradable and non-staining on plant surfaces.
Application rates and timing
Application Guidance: Use the crop-specific foliar or fertigation rates listed below. The datasheet recommends treating between 6 and 25 °C and avoiding applications during extreme drought, high humidity, frost or rain.
Foliar application

|---|---|---|---|
| Cereals | Not specifically stated in the datasheet | 150-250 cc/hL | |
| Citrus | From the beginning of budding | 200-300 cc/hL | 2-3 applications. |
| Fruit trees | From the beginning of budding | 200-300 cc/hL | 2-3 applications. |
| Horticultural crops | As needed and according to crop development | 150-300 cc/hL | 3-4 applications. |
| Olive trees | From the beginning of budding | 200-300 cc/hL | 2-3 applications. |
| Rice | For copper deficiency correction | 150-250 cc/hL | |
| Vine | Until veraison | 200-300 cc/hL |
Fertigation / drip irrigation
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Citrus | 1) Near vegetative cessation; 2) At the onset of budding; 3) During full vegetative activity | 6-12 L/ha | Apply 2-3 times. |
| Fruit trees | 1) Near vegetative cessation; 2) At the onset of budding; 3) During full vegetative activity | 6-12 L/ha | Apply 2-3 times. |
| Horticultural crops | As needed and according to crop development | 5-10 L/ha | 3-4 applications. |
| Olive trees | 1) Near vegetative cessation; 2) At the onset of budding; 3) During full vegetative activity | 6-12 L/ha | Apply 2-3 times. |
| Rice | For copper deficiency correction | 5 L/ha |
