Salinité

Class: stress abiotique
Common Name: Salinité
Symptoms:

Toxic levels of sodium chloride (table salt) cause salt damage to crops. High concentrations of sodium chloride can have a devastating impact on seed germination and create osmotic stress causing plants to become water deficit. High concentrations of sodium chloride can also cause ion imbalances and toxicity that is seen on older leaves as burned tips, which can develop into more extended necrosis.

Control Measures

Vérifiez le niveau de sels dans le sol avant la plantation. Tenez compte de la sensibilité de la culture au chlorure de sodium, de la structure et des caractéristiques du sol, ainsi que de la qualité de la source d’eau. Si nécessaire, prenez des mesures préventives qui améliorent le drainage global ou démarrez plusieurs exécutions par irrigation à fort volume avant de planter des cultures pour laver et repousser les sels.

Cherchez régulièrement des symptômes visuels de salinité, surtout après de fortes pluies. Cela améliorera les temps de réponse pour éviter des dommages graves.

Remarque : l’arrêt ou la réduction significative d’un programme de fertilisation régulier et équilibré peut ne pas affecter la situation. En fait, cela peut causer plus de dégâts car les nutriments essentiels peuvent devenir déficients.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
