Chloride
Symptoms of Chloride Deficiency
- Wilting
- Restricted, highly branched root system
- Leaf mottling
- Leaflet blade tip wilting with chlorosis
- In cabbage, absence of cabbage odor
Function of Chloride
- Cation balance, transport
- Diminishes effect of fungal infections
- May compete with nitrate uptake, promoting use of ammonium, which may factor in its role in disease suppression
- Works in tandem with K for the proper function of stomatal openings, controlling internal water balance
- Photosynthesis specifically the  control of gas/water exchange
Treatment Options
Avoid applying Chlorides early in ground as it interferes with Phosphorus and Nitrate uptake. Use as a foliar to improve disease control and promote health in the crop. Crops such as canary seeds require high levels of Chlorides. Chlorides have a low deliquescence point and can be taken up fast by the leaves causing a leaf burn. Apply with high volume of water early in the morning or late at night. .
