AI Technical Summary

Benefits of technology

The present invention provides a method for providing nutrients to plants and reducing disease incidence in plants. This is accomplished by applying a water-soluble nutritional composition containing yeast hydrolysate and a metal salt to the foliage of the plant. The metal salt can be selected from the five metals mentioned above, with copper, nickel, zinc, iron, and manganese being examples of metals that have higher solubility. This method allows the metal salt to be absorbed into the plant, providing important nutrients to support its growth and development.

Problems solved by technology

Plants with minor deficiencies in desirable metals may display no visual symptoms, but can have reduced growth and plant yield.

example 1

[0024]The solubility and uptake of the composition of the present invention and comparative commercial products was tested.

[0025]The composition of the present invention, embodied by COP-R-QUIK®, available from Natural Ag Solutions in Sebring, Fla., has 12 wt. % copper derived from copper nitrate in an aqueous solution of amino acids.

[0026]The inventive composition was compared to commercially available products MAGNA-BON® CS2005™ and KOCIDE® 3000.

[0027]MAGNA-BON® CS2005™ is available from Magna-Bon® Agricultural Control Solutions (Florida, USA) and is described on its website (www.magnabon.com / cs-2005) as a copper sulfate pentahydrate, acidic, liquid pesticide. An MSDS (dated 5 / 11) for Magna-Bon CS 2005™ shows a concentration of copper sulfate pentahydrate in the range of 18.81-20.79%.

[0028]KOCIDE® 3000 is available from DuPont (Wilmington, Del.) and is typically sold as a granular product intended to be mixed in water prior to use as a fungicide / bactericide. The granular product h...

example 2

[0035]A greenhouse study was conducted on citrus plants. Three solutions containing different sources of zinc were tested for metal solubility and uptake into the leaf of the citrus plants, with one set of control pots. The study was replicated six times.

[0036]The nutrient solutions tested were: Solution A of the invention was zinc nitrate, Comparative Solution B was zinc sulfate, and Comparative Solution C was a tank-mixed zinc sulfate plus 1 wt. % K2O, resulting in an insoluble precipitate. The solutions were prepared to each provide a theoretical 0.1 wt % Zn (as metal).

[0037]Each plant was sprayed with the respective nutrient solution and analyzed 0.1, 1, 2 and 3 days after spraying. The entire study was repeated three times.

[0038]Leaf samples were taken and analyzed at the University of Florida UF / IFAS Extension Soil Testing Laboratory in the manner described in Example 1 to determine the plant's uptake of zinc.

[0039]The results are demonstrated in Table 2. The results show that...

example 3

[0040]A greenhouse study was conducted on pecan plants. Three solutions containing different sources of zinc were tested for metal solubility and uptake into the leaf of the pecan plants, with one set of control pots.

[0041]Solution A representing a composition of the present invention, embodied by NUTRE-QUIK® Zinc, available from Natural Ag Solutions in Sebring, Fla., has 23 wt. % zinc derived from zinc chloride in an aqueous solution of amino acids.

[0042]The inventive composition was compared to zinc nitrate (Comparative Solution B), also containing a metal salt according to the present invention, but without the aqueous solution of amino acids, and zinc sulfate (Comparative Solution C).

[0043]Solutions were used to treat plots containing the same elemental zinc concentrations, using the three different sources of nutritional zinc noted above. The amount of solution was selected to provide a theoretical 0.091 wt. % zinc (as metal) from each treatment solution.

[0044]24 pecan plants w...

Abstract

A foliar nutritional composition and method for using same for providing nutrients and / or for treating disease in plants. The foliar nutritional composition comprises a metal salt complexed with amino acids from hydrolyzed yeast extract. The metal salt is selected for high solubility using a salt of a metal selected from the group consisting of copper, nickel, zinc, iron, manganese, and combinations thereof. Preferred metal salt are nitrates, chlorides, and combinations thereof. In the method, an aqueous solution of this composition is sprayed on the plant foliage and absorbed by the plant.

Description

RELATED APPLICATION[0001]This application claims priority from U.S. Provisional Application Ser. No. 62 / 194,020 filed Jul. 17, 2015, pending, and is a continuation in part of U.S. patent application Ser. No. 15 / 132,643, filed Apr. 19, 2016, pending.FIELD OF THE INVENTION[0002]The present invention relates to foliar nutritional compositions and methods for providing nutrients, preventing disease in plants and enhancing the resistance and / or tolerance of plants to disease, as well as treating, suppressing, and / or controlling plant disease inhibited by metals, using a foliar nutritional composition according to the present invention.BACKGROUND OF THE INVENTION[0003]Certain metals, such as iron, copper, zinc, manganese and nickel, are recognized as essential for plant growth. The range for such metals in most plant tissue has been considered low and may in such amounts often be considered readily available in the soil.[0004]Nevertheless, certain metals are key components of some plant e...
