The present disclosure relates to an improved nitrification inhibitor composition and its use in agricultural applications.

The instant invention relates to methods for increasing or promoting microbial activity in soil selected for treatment.

Methods for stimulating plant growth and/or promoting plant health using free enzymes or recombinant microorganisms that overexpress enzymes are provided. Plant seeds coated with free enzymes or recombinant microorganisms that overexpress enzymes are also provided. Compositions comprising a fertilizer and an enzyme or a recombinant microorganism that overexpresses an enzyme are provided. Modified enzymes having ACC deaminase activity, recombinant microorganisms expressing the modified enzymes, plant seeds treated with the modified enzymes or recombinant microorganisms, and methods for stimulating plant growth and/or promoting plant health using the modified enzymes or recombinant microorganisms are also provided.

A composition is provided comprising as component (A) at least one insecticide; and as component (B) at least one fertilizer. The composition is effective in controlling nematodes and in promoting plant growth. The at least one insecticide is preferably selected from thiodicarb, abamectin, imidacloprid, fipronil and mixtures thereof. The fertilizer component preferably comprises one or more amino acids and one or more micronutrients. A method of controlling nematodes and/or promoting plant growth using a combination of component (A) and component (B) is also provided.

A nematicidal fertilizer composition comprising one or more amino acids and one or more micronutrient compounds. A method of controlling nematodes at a locus is also provided. The method comprises applying to the locus one or more amino acids and one or more micronutrient compounds.

A method of delivering at least one nucleic acid to a plant, comprising: applying a light energy to a surface of the plant to create a pore; and applying at least one nucleic acid to the pore, wherein the at least one nucleic acid comprises RNA, wherein the at least one nucleic acid comprises at least one of a RNA interference (RNAi), an antisense RNA (asRNA), a micro RNA (miRNA), a small interfering RNA (siRNA), a double-stranded RNA (dsRNA), a non-coding RNA (ncRNA), mitochondrial RNA (mtDNA), and combinations thereof.

A process for treating plants, including the application of at least one compound, termed carbonic ester of glycerol, including at least one carboxylic ester function formed by a carbonic acid-derived group and at least one glycerol-derived group, with the exception of cyclic glyceryl carbonate including five ring members.

This invention provides low-dose, low-concentration formulations of phytotoxic trace inorganic compounds for use in methods and systems for selectively and effectively controlling invasive plants.

A composition including (a) at least one (thio)phosphoric acid triamide (T) according to the general formula (Ia)

R.sup.a1R.sup.a2N—P(X)(NH.sub.2).sub.2  (Ia)

wherein X is oxygen or sulfur; R.sup.a1 is a C.sub.1 to C.sub.20 alkyl, C.sub.3 to C.sub.20 cycloalkyl, C.sub.6 to C.sub.20 aryl, or dialkylaminocarbonyl group; R.sup.a2 is H; or R.sup.a1 and R.sup.a2 together with the nitrogen atom linking them define a 5- or 6-membered saturated or unsaturated heterocyclic radical, which optionally comprises 1 or 2 further heteroatoms selected from the group consisting of nitrogen, oxygen, and sulfur; and (b) at least one specific herbicide.

Disclosed are compositions comprising chitosan, glucosamine and amino acids, where the concentration of chitosan is greater than 1.5 wt % and glucosamine is greater than 1.5 wt %. In preferred embodiments the concentration of chitosan is from 2 to 2.5 wt % and glucosamine is 2 to 6 wt %. The composition can also include solid chitin. The composition can also include trace elements, protein and other polysaccharides. The composition is generally a liquid but may be a solid. In most embodiments, the solid can be reconstituted with water prior to use. In preferred embodiments, the composition comprises HYTd and at least one of, HYTa, HYTb and HYTc. In other embodiments the composition comprises HYTd and two or more of, HYTa, HYTb and HYTc. The composition can also comprise HYTd, HYTa, HYTb and HYTc. In the disclosed processes soil, seed, seedling or plant foliage are contacted with HYTd or any of the above compositions.
