A biological seed-coating agent (SCA) including a fermentation broth obtained based on co-cultivation of Trichoderma and Bacillus sequentially inoculated, and a preparation method thereof are provided. According to a principle of synthesis biology, Trichoderma that induces disease resistance and stress resistance and Bacillus that antagonizes pathogens and promotes crop growth are inoculated in stages for co-fermentation to prepare a microbial co-culture solution. The microbial co-culture solution is mixed with diatomaceous earth and brassinolide according to a specified ratio to prepare a biological SCA in a dosage form of a powder. The biological SCA includes high contents of spores and antagonistic and growth-promoting substances.

A composition that contains at least citrus oil, pine oil, and salt water is effective in mitigating or eliminating a detrimental microbial, in one example, a gram-negative bacteria disease in plants. This mixture is effective against citrus greening and other gram-negative bacteria diseases. A mixture containing at least the foregoing components can be used as a root and/or a foliar treatment by diluting a concentrated mixture of the composition and spraying it on the leaves of a diseased plant or one that is prone to disease. Similarly, the combined composition can be used as a root drench or in an irrigation system to treat a diseased plant. Additional active components in a composition as disclosed herein may optionally include a surfactant (especially in a foliar application) and a growth stimulant (especially in a root drench or irrigation application).

Provided herein are stabilized, ready-to-use, quick break emulsion compositions (oil-in-water emulsion compositions), and in particular, stabilized paraffinic spray oil compositions and methods of using these compositions for controlling plant pests such as harmful insects and fungi. The oil-in-water emulsion compositions comprise a stabilizer which is benzoic acid, benzoic acid salt, benzoic acid derivative, paraben or a mixture thereof.

An agricultural co-formulation comprising: an effective amount of at least one plant growth regulator, or at least one plant growth regulator and an additional biologically active ingredient, in a comminuted form having an average particle size in the range of from 1 to 12 microns; at least one oil; at least one oil-soluble surfactant dispersing agent; and at least one emulsifying agent, wherein the final concentration of the at least one plant growth regulator, or at least one plant growth regulator and an additional biologically active ingredient, is optionally adjusted by adding additional oil and one or more rheology modifiers and/or activation agents as required to substantially stabilise the co-formulation; and wherein the efficacy of the plant growth regulator is substantially maintained or improved; and one or more methods of making the co-formulation.
