Provided herein are compositions and methods to improve plant resistance to abiotic and biotic stress, thereby improving crop yield. Provided herein are compositions including zinc, copper, and an acid, where the acid is selected from citric acid, sulfuric acid, oxalic acid, humic acid, fulvic acid, boric acid, acetic acid, and a combination thereof. Certain embodiments optionally include ammonium sulfate. Compositions described herein have plant priming activity where the plant's defenses against abiotic and biotic stress are boosted.

A respiration filtering face mask that can be washed and sterilized by common means and reused repeatedly comprised of a filtering component that is a laminate of at least one layer of particle filtering material and at least one layer of a microbe killing metallic woven cloth laminated together by adhesive or fusible material in a manner that allows low resistance to air flow, cut to a shape that is folded into a modified cone, a padding filled gasket that is continuously sealed to the outer edge of the filter cone, harness straps that are elastic and user adjustable for length and tension, and an attached shield to prevent fogging of eye ware. A method for making said anti-microbial filter and respiration filtering face mask.
