▏Applications

● Be applied as a foliar spray or through the drip irrigation system. 
● The application rate depends on the crop stage, plant tissue and soil Analysis. In the absence of such analysis the following rate can be considered:
● Soil application: Direct application or Fertigation. 
- Fruit trees, citrus & grapes 2-3.5 Kg/ha starting from spring. Repeat 2-3 times according to needs.
- Vegetables 3-6 Kg/ha starting early in the season. Repeat several times throughout the cycle.
- Field crops: 7-12 Kg/ha with soil preparation or sowing.
- Ornamentals: 2-3.5 Kg/ha; repeat the application if needed 3-4 times in the season.
● Foliar application:
- Fruit trees, citrus & grapes: 1 Kg/ha before flowering. Repeat the application 2-3 times on new shoots (for citrus).
- Vegetables: 1-2 Kg/ha starting from the vegetative growth. Apply periodically throughout the cycle.
- Ornamentals: 2 Kg/ha when enough foliage to absorb the spray. Repeat if symptoms appear.
