TMT Aqueous Solution for Plant Growth Promotion

The patent applies parameter changes by adjusting the concentration of TMT from the traditional high concentration (15% aqueous solution) used for heavy metal precipitation to low concentrations (0.01-0.1% w/v) for plant growth promotion and antifungal treatment. This parameter adjustment enables the same substance to serve multiple functions: at low concentrations it promotes plant growth and inhibits fungal pathogens, while at high concentrations it effectively precipitates heavy metals. The patent thus resolves the contradiction by demonstrating that different concentrations of TMT achieve different functional outcomes, expanding its adaptability while maintaining reliability in each specific application.

The patent extracts TMT from the soil remediation context and applies it directly to plants through foliar spray or stem application. Instead of mixing TMT into the soil for heavy metal remediation, the invention extracts the active substance and delivers it directly to the plant target, achieving both growth promotion and antifungal effects without the complexity of soil mixing and distribution. This resolves the contradiction by simplifying the application process while maintaining or enhancing efficacy.

The patent applies universality by demonstrating that TMT performs multiple functions simultaneously: it promotes plant growth, initiates early fruiting, and provides antifungal protection against pathogens such as Phytophthora, Phellinus, and Fusarium species. This single substance replaces the need for separate fertilizers, growth regulators, and fungicides, resolving the contradiction by providing both growth enhancement and harmful factor protection through one multi-functional agent.
