Effects and characteristics:
Induce plants to produce systemic acquired resistance to pathogen invasion, such as tobacco’s resistance to tobacco mosaic virus. Regulate the opening and closing of plant stomata to help plants reduce water loss during drought. Participate in the growth and development of plants, such as seed germination and root growth.
Precautions:
Salicylic acid may be toxic to plants at high concentrations, so it should be used strictly according to the recommended concentration. The effects of salicylic acid may be affected by environmental factors (such as temperature and humidity), so these factors should be considered when using it. Its metabolic process in plants is relatively complex, and excessive use may interfere with the normal physiological metabolism of plants.
