Does anybody worked with salicylic acid applicationn on foliage of trees in order to reduce environmental stress?
Salicylic acid, like ascorbic acid, is a well known anti oxidant in plants. The chemical, therefore, no wonder, is used against both biotic and abiotic stresses. The compound can mitigate abiotic stresses like dehydration, heavy metals, salinity stress etc., wherein many reactive super oxide radicals are produced, which left to themselves, can cause heavy oxidative damages resulting in membrane leakage . The spray of antioxidants can come to the rescue.. Dehydrating foliage can also recover. And salicylic acid can also act as growth regulator leading to growth enhancement and photosynthetic yield
SA foliar spray Is feasible in the case of trees. How is it in the case of plantation crops
salicylic acid very well can be used as a foliar spray like triazole compounds, GA3, 2,4-D, many herbicides and pesticides. It causes no harm and it is biodegradable in the soil. One has to work out the cost benefit ratio.
In continuation, I have no knowledge at all whether salicylic acid has been used in plantation crops. One should go through the literature and find out what are the compounds that can be used to mitigate stress in plants. The effectiveness of the compound and the nature of stress should be taken into account. Finally the economic feasibility should be worked out. Added to this one must find out the residual content of the compound left out with the foliage and the percentage of degradability both in the plant and in the soil must also be known
