The planting of novel economic crops is increasingly hot, but pesticide residues caused by pesticide application for pest control exceed standards, and the planting of novel economic crops also increasingly becomes the focus of attention on dining tables of common people.

Phosphorous acid (KH), a major non-pesticide control material currently being widely used in developed countries₂PO₃) After the successful research and development of a disease control medicament 'Fossido' originated in 1980, the main disease inhibiting substance is found to be phosphorous acid in metabolites thereof, which can stimulate host plants to start a defense system to generate antibiotic substances, and the antibiotic substances can be absorbed by plant leaves and root systems after application and conveyed into the body to play a direct sterilization function, and simultaneously, the defense system is started to enable the plants to generate disease resistance to resist invading pathogenic bacteria. When the pathogenic bacteria invade, the pathogenic bacteria can be applied and controlled by a disease prevention mechanism of non-pesticide control substances, namely phosphorous acid and phosphite, and the pathogenic bacteria are also identified by plant cells, so that a phosphite starting defense system generates plant resistin and PR protein to directly attack the pathogenic bacteria, and a warning signal is sent to call other uninfluenced cell starting defense systems, and then additional protein is added to polysaccharides to strengthen cell walls, so that the pathogenic bacteria can be suppressed or killed by the reaction of plant bodies. The disease Resistance of phosphorous acid and phosphite is a Systemic disease Resistance (SAR) acquired in the future, also called induced Systemic disease Resistance (ISR), and belongs to one of the broad biological control.

In the past, the control personnel usually use industrial grade phosphorous acid and potassium hydroxide dissolved in water in a ratio of 1: 1; the phosphorous acid is dissolved in water and then the potassium hydroxide is dissolved, so that the preparation of the better phosphorous acid solution is time-consuming and labor-consuming, the operation is complicated for a plurality of farmers on the same day, and the misoperation is easy to cause the failure of the efficacy and the fertilizer efficiency and even the adverse effect on the skin of the farmers under the condition of no certain knowledge of chemical synthesis.
