RVR Disease Control Fertilizer Series.
Disease Control adds phosphorous acid to strengthen resistance. Phosphorous acid is also used for preparing phosphite salts, as well as aqueous solutions of pure phosphorous acid, have shown effectiveness in controlling a variety of microbial plant diseases, in particular, treatment using either trunk injection or foliar containing phosphorous acid salts is indicated in response to infections by phytophthora and pythium-type plant pathogens, effective for 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). 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.
