Embodiment 1

[0086] Embodiment 1-preparation of silver dihydrogen citrate

[0087] Water is fed into a reverse osmosis device and passes through a semi-permeable membrane to remove impurities to obtain deionized water. Anhydrous citric acid of 99% purity was mixed with this water to obtain 200 gallons of a 20% (w / v) solution (796 g citric acid per gallon of water). The 200 gallons of 20% citric acid were introduced into an ion chamber containing positive and negative electrodes, each composed of 200 troy ounces of 999 pure silver. The positive and negative electrodes were separated by at least 2.0 mm, allowing the citric acid solution to pass between the two electrodes. An ion generation controller (IGC, ion generation controller) power supply including positive and negative conductors is connected to the positive and negative electrodes. The IGC passed a current of 5 amps at 17 volts, one pulse every 9 seconds, with 1 minute intervals between polarity changes. Throughout the process, ...

Embodiment 2

[0091] Efficacy evaluation of embodiment 2-SDC preventing and controlling the spore germination of Phakopsora pachyrhizi

[0092] Soybean leaves showing Asian soybean rust damage were harvested; the leaves were kept moist to have the maximum number of available spores. The leaves were examined with a stereoscope to identify those with high sporulation. Cut the leaves into standard sized pieces.

[0093] Three different concentrations of SDC containing 5 ppm, 10 ppm and 15 ppm silver were prepared in distilled water. Put 10ml of each solution into separate test tubes. 10 pieces of selected soybean leaves were placed in each test tube and agitated to suspend the spores in the rust spots. The same procedure was used for the control, but SDC was omitted from the solution. The leaves were left in the solution for 2 hours. For each product dilution, 10 petri dishes containing water-agar medium were inoculated with 100 spores per dish and kept in the dark for 6 hours. A lacto...

Abstract

A method for treating a plant, the method comprising contacting a composition comprising silver dihydrogen citrate with at least one of the plant, a portion of soil and / or groundwater proximal to the plant, or a combination thereof.

Description

technical field [0001] The present disclosure relates to compositions and methods for treating and / or preventing plant diseases. Background technique [0002] Plant diseases have a huge impact on agriculture and related industries. In the United States alone, the total economic cost of crop disease is estimated to exceed $30 billion per year. In addition to the costs associated with treatment and prevention, plant diseases can lead to reduced crop yield, reduced quality, reduced nutritional value, reduced resistance to pests and other diseases, and reduced fertility. [0003] Plants are susceptible to a variety of pathogens, including fungi, oomycetes, bacteria, viruses, and other virus-like organisms. Each of these classes of pathogenic organisms is quite distinct and represents such clades of biological groups as unicellular bacteria, multicellular fungi, and subcellular viruses. In their natural environment, many of these pathogens are at the mercy of natural predators...
