Potassium phosphite is non phytotoxic and having very minimal pathogen resistance. Alternating the two treatments causes similar . This market was pioneered by Bayer with Aliette and fosetyl aluminium. Non persistent in the environment, as readily oxidized to phosphate by soil microbes, and also has very low mammalian toxicity. in plants. Figure 2. 1960s, led in turn to more . Among 54 isolates assayed for phosphonate insensitivity, 96% had EC 50 values that exceeded the maximum allow rate of the fungicide used in the assays. In field trials, they reduced root rot to near zero levels. A sound knowledge of fungal biology and fungicidal mode of action is important for determining how . Calcium and magnesium phosphite may also be used. . Insensitivity to the maximum allowable rate of a phosphorous acid fungicide was widespread within and among hop farms in Oregon. 3.2.2. . Mode of action: General fungitoxic effect . With potassium phosphite, the incidence of the disease varied between 27.9 and 32.4%; with potassium bicarbonate, it was between 19.9 and 29.5%, and in the control, variation went between 44.1 and 47.4%. For more . The list of FRAC codes was developed by the Fungicide Resistance Action Committee and is a technical classification of fungicide modes of action according to scientific data.
