Disease Control 0-0-20 is a clear blue liquid with high Phosphorus Acid + 600g/ L to increase strength of crops and prevent crops infection. Disease Control 0-0-20 contains the combination of nitrogen, available phosphate and soluble potash to stimulate root development, plant growth and fruit set. The series adds phosphorous acid to strengthen resistance. Phosphorous acid is an effective fungicide against Oomycete pathogens, such as Phytophthora, Phythium, and Downy mildews for a number of crops. Phosphorous acid has both a direct and indirect effect on these pathogens and inhibits a particular process ( oxidative phosphorylation) . Moreover, according to some evidences, phosphorous acid has an indirect effect by stimulating the plants natural defense response against pathogen attack. After absorbing phosphorous acid, it is possible that when these products are applied to plant root systems or in the soil, soil microbes could convert these compounds to phosphate which would be available to the plant as a phosphorus nutrient. Using phosphorous acid along with phosphate is a good idea to make sure that the plants are not deficient in phosphorus. Disease Control 0-0-20 may be placed on the surface of the soil or directly spray on the crops every 7 to 15 days. Disease Control 0-0-20 is designed for use in all soil types. It should be concentrated for maximum response. Disease Control 0-0-20 is effective before or at diseases caused. Multiple applications may be beneficial.
