The present disclosure describes agrochemical water immiscible solvent-in-water (e.g., oil-in-water) emulsion formulations that include one or more agrochemical active agent(s), a continuous aqueous phase containing a sulfo polymer, and a discontinuous water immiscible phase substantially homogenously incorporated in the aqueous phase, and optionally a rosin. The present disclosure also describes methods of making and using such emulsion formulations in agriculture.

In production of crops of agriculture and horticulture or the like, damage caused by diseases is still large, and, due to factors such as occurrence of resistant diseases to existing drugs, development of new agrohorticultural fungicides is desired.

General formula (I)

##STR00001##

As a result of intensive research to develop novel fungicides, the present inventors found that the compound represented by the general formula (I) of the present invention or a salt thereof is useful as an agrohorticultural fungicide to complete the present invention.

The present invention discloses an application of an endophytic fungi FO-R20 in prevention and treatment of rice neck or panicle blast, and belongs to the technical filed of microbial applications. The Falciphora oryzae FO-R20 with a deposit number of CCTCC M 2021505 is prepared into a seed coating agent or solid fungal fertilizer and applied to rice seeds; and in the culture process, the strain is colonized at the roots of rice, thus the disease resistance of rice to neck or panicle blast is remarkably enhanced, the prevention and treatment efficiency reaches 86.91%-90.85%, and the disease index is reduced by 64.92-72.07. The biological prevention and treatment effect of the endophytic fungi Falciphora oryzae FO-R20 against rice neck or panicle blast has great value by promotion and applications thereof in the field of agriculture.

This disclosure includes a method of protecting crops from Cercospora leaf spot, by the foliar application of brassinosteroids. The method is able to be based on natural and synthesized material, 24-epibrassinolide and other commercial brassinolides, in contrast to those conventional fungicides cause pathogen resistances and the harm to human and the environment. This disclosure provides alternative and safe option against Cercospora leaf spot diseases.

A strain of Pseudomonas aeruginosa 9 # and its applications are disclosed, which relates to the technical field of microorganisms. The deposit number of the Pseudomonas aeruginosa 9 # of the disclosure is CCTCC NO: M 2021178. The strain of Pseudomonas aeruginosa 9 # can inhibit the growth of the Ustilaginodea vixens strain YY7850, which is the first instance that the Pseudomonas aeruginosa strain has been found to antagonize the pathogen of rice false smut. In view of the ability of strain 9 # to inhibit the pathogen of rice false smut, the strain has the potential to be developed into a biocontrol bacterium of rice false smut.
