The marine algae is dried out firstly and then the marine algae are soaked in water for overnight. In the next day, the marine algae is decanted and then strained. Afterthat the decanted algae is mixed with the water using the pump in bottle and then sprayed on the brinjal (Solanum melongena) crop. It is a traditional practice.The marine algae are found only in the sea. Due to less availability of marine algae, the urine of cow or ash can sprayed on the crop also.The infected stem of brinjal plant can be removed as the last option for the prevention.
Crop Family: Solanaceae
Crop Scientific Name: (Solanum melongena)
Crop Vernacular Name: Baigan, Ringad
Formulation: Marine algae, the urine of cow and ash
Ingredients: Marine algae OR Urine of cow, Ash, Water
"Marine macroalgae are plant-like organisms with simple internal structures that generally live in coastal areas. They mainly include different communities of red, brown and green macroalgae. Marine macroalgae commonly occupy intertidal and sublittoral-to-littoral zones on rocks and other hard substrata. They are considered to be an excellent natural biosource in different aspects of agricultural fields. They have great proficiency in improving soil physical and chemical properties. Marine macroalgae are also characterized by producing a large array of biologically active biocidal substances against plant-infecting pathogens." [Seham M. Hamed, Amal A.

"With the rising popularity of organic farming, due to adverse effect of chemicals, the seaweed fertilizer industry is growing rapidly worldwide. Seaweeds act as natural plant growth stimulator and enable the plants to withstand drought, disease or frost. Root diseases of tomato and sunflower caused by root rotting fungi, Fusarium spp., Rhizoctoniasolani and Macrophominaphaseolina, and root knot nematode, Meloidogyne spp., are the major constraints in tomato and sunflower production. In our studies, ethanol and water extracts of several seaweeds showed significant nematicidal activity against Meloidogynejavanica. In this study, efficacy of three seaweeds Spatoglossumvariabile, Melanothamnusafaqhusainii and Halimeda tuna was compared with a fungicide Topsin-M and a nematicidecarbofuran both in screen house and under field condition. Seaweed and pesticides showed more or similar suppressive effect on root pathogens of tomato and sunflower by reducing fungal root infection and nematode's galls on roots and nematode's penetration in roots. However, mixed application of S. variabile with carbofuran caused maximum reduction in nematode's penetration in roots and produced greater fresh shoot weight, root length and maximum yield of tomato under field condition. Seaweeds offer a non-chemical means of disease control, which would also protect our environment from the use of hazardous chemicals."
