A modified bentonite of biostatic and biocidal properties, the modified bentonite comprising intercalated bentonite grains, wherein each of the intercalated bentonite grains is intercalated with at least two different metal ions selected from the group consisting of silver ions (Ag.sup.+) and dipositive metal ions (Me.sup.2+).

An anti-bacterial composition for plants including garlic oil; cinnamon oil; yucca stem oil; oleic acid; hemp seed oil; and dimethyl sulfoxide.

An antibiotic composition contains, as an active ingredient, a diatomaceous earth-zinc oxide composite comprising zinc oxide on diatomaceous earth, and an antifungal combination preparation G contains a diatomaceous earth-zinc oxide composite including zinc oxide on diatomaceous earth and an antifungal agent. The antibiotic composition is less toxic while exhibiting excellent antibiotic activity, for example, antiviral, antibacterial or antifungal activity. The antibiotic composition is usable to prevent contamination or infection by viruses, bacteria or fungi, inhibit the growth of viruses, bacteria or fungi, or treat infections by viruses, bacteria or fungi.

An aqueous disinfectant solution having a stable ionic form of metals like silver, copper, and zinc in combination having significant ability to kill or disabling microorganisms and acts as antifungal as well with an extended useful shelf-life characterized by its noncorrosive nature and possesses better residual efficacy.

An agricultural spray may be produced by admixing citric acid and glutamic acid with a metal salt and a pesticide or other agricultural chemical containing components capable of precipitating with the metal salt in the admixture. The citric acid and the glutamic acid chelate with the metal salt to provide a stability and compatibility-enhancing composition, thereby preventing the metal salt from forming an insoluble solid within the admixture. Such a composition may be produced by admixing citric acid and glutamic acid at a molar ratio of about 6.8:0.5 to about 1:0.29. The composition may include a metal sat, citric acid and glutamic acid in a molar ratio of about 1:6.8:0.5 to about 1:1:0.29 and a pesticide.
