Foliar Spray and Soil Application of Seaweed Extract

     Seaweed Extract is a natural biostimulant for plant growth, stress tolerance and nutrient enhancement.

     Seaweed extract It is a much better alternative than chemical fertilizer and excels well in the areas of sustainable agriculture and organic farming. It performs as a superior water soluble liquid for soil application and it is also available in dry form. There are several ways to use it, but foliar spray and soil application are the preferred methods. These can be done as a foliar spray (mixing with water according to the product’s dilution instructions) or as a soil drench for a more gradual nutrient delivery.

     Foliar spray applications are effective in eliciting early vegetative growth and promoting seedling establishment.Seaweed Extract It helps to suppress diseases and insect pests, boosts nutrient uptake, enhances root development, flowering and fruit set. It is also helpful in reducing seed dormancy and enhancing the vigor of the crop plants. It is a rich source of various plant hormones such as auxins and gibberellins. It is also loaded with vitamins and minerals such as iron, copper, manganese, zinc and molybdenum. It also contains a number of phenolic compounds which act as an antioxidant to protect plants from oxidative damage caused by UV radiation.

Moreover, it enhances resistance to abiotic stresses such as drought, cold and salinity stress.Seaweed Extract It can also elicit a variety of defense responses against pathogens by modulating the expression of several genes such as salicylic acid, jasmonic acid and ethylene. It can also protect plants from the effects of heavy metals by chelating these toxic elements.

     Furthermore, it has been found that seaweed extract can reduce oxidative damages caused by UV rays and chemical treatments.seaweed extract It can prevent photosystem II degradation and oxidative damage to protein and lipids of plant cells. It can also increase the efficiency of photosynthesis by reducing water loss from the leaves and improving stomatal conductance.

     Other benefits of using the extract include improved quality of the produce, higher yields, and reduced harvest losses. For example, the application of a solution containing Codium tomentosum as a postharvest spray led to an increase in anthocyanins and total phenolics in strawberry fruit. It also reduced browning index by inhibiting the activity of polyphenol oxidase and peroxidases. It can also help in preventing deterioration of fruits by preserving moisture content and increasing the shelf life of the produce. It can be used during all stages of crop production from germination to post-harvest processing. It is also useful in improving the texture, color and flavor of the produce. In addition, it can be used as an alternative to synthetic plant growth regulators and fungicides. The extract is also eco-friendly, biodegradable and non-toxic. It is also more cost-effective and safer than chemical products.
