“NOVEL COMPOSITION OF SILICA WITH PHENOLIC COMPOUNDS TO ENHANCE YIELDS AND DECREASE BIOTIC AND ABIOTIC

STRESSES”

TECHNICAL FIELD OF THE INVENTION:

The present invention relates to novel composition comprising silica and phenolic compounds for agricultural applications. More particularly, the present invention relates to novel composition comprising silica and phenolic compounds to enhance the yields of agricultural produce and decrease Biotic and Abiotic stresses in the plants.

BACKGROUND AND PRIOR ART OF THE INVENTION:

Silicon as nutrient has been gaining prominence over the last 3 decades. Silicon supplementation has been shown to provide increased yield, produce quality, crop stresses etc.

From early l990’sonwards silicates in foliar sprays were in use. In 2003, foliar sprays with (stabilized) silicic acid were introduced, and more recently foliar sprays with silica nanoparticles have also been applied to the plants. Foliar sprays with silicates are effective as pesticides. The limited data on foliar silica sprays show a tendency to decrease biotic stress and to stimulate a limited increase in growth and yield. There is ample literature available on silica based compositions for foliar spray.

US20130130902 discloses dissolved silicate compositions in which the dissolved silicate is stabilized by at least two selected osmolytes and is therefore bioavailable.

EP2309862A2 discloses a foliarly applicable plant nutrient composition which comprises, in aqueous solution, (a) a first component comprising an agriculturally acceptable source of foliarly absorbable silicon; (b) a second component selected from agriculturally acceptable sources of thiosulfate ions, agents effective to inhibit polymerization of silicic acid or silicate ions, and mixtures thereof; and (c) as a third component, an agriculturally acceptable mixture of compounds selected from the group consisting of organic acids, organic compounds having functional groups capable of reversibly binding or complexing with inorganic anions, and mixtures thereof.

US8221791B 1 describes silica based antibacterial and antifungal nanoformulation for agricultural purposes having a plurality of copper ions embedded in a silica nanogel, and wherein the plurality of interconnected nanoparticles of the nanogel contain a plurality of Cu ions electrostatically bound to the nanoparticle core, a plurality of Cu ions covalently bound to a hydrated shell surface and nanopores of the nanoparticle, and a plurality of Cu oxide/hydroxide as nanoclusters/nanoparticles bound to the surface of the nanoparticle.
