Two factors are probably responsible for the reduced resistance risk with phosphonate products; (a) the mode of action in target fungi may involve several sites, and (b) the involvement of host defenses in disease suppression. ProPhyt. Phosphonate compounds also occur naturally in some lower life forms, including protozoa, mollusks, coelenterates, and oomycete fungi (6). You must have JavaScript enabled in your browser to utilize the functionality of this website. One means of reducing the acidity of phosphonic acid is to neutralize it with an alkali salt; typically potassium hydroxide (KOH).

Entering your postal code will help us provide news or event updates for your area. Phosphonate fungicides have very good efficacy for Pythium diseases and other diseases caused by oomycete fungi when applied preventatively; but are thought to have poor efficacy when applied post-infection (after disease symptoms and signs are apparent.).

Pythium aphanidermatum growing in cornmeal medium amended with (a) potassium phosphite and (b) potassium phosphate. McDonald, A.E., B. Lowering the amount of phosphate in the media allowed direct inhibition of fungi by the phosphite ion. The mode of action of phosphonate fungicides has long been a source of controversy and mystery. Listed below are common and trade names of select fungicides currently registered in the United States representing the major fungicide groups and chemistry within these groups (chemical group), plus the mobility, activity, and risk of resistance developing to these fungicides. FUNGICIDE RESISTANCE WARNING . When concentrations of phosphite ions in the roots were low, host defense enzymes were stimulated; but when concentrations of phosphite ions were high, host defense enzymes remained unchanged and the phosphite ions inhibited growth of the pathogen before it caused disease (7). POSSIBLE TO THE DAY OF INFECTION AND ALTERNATED WITH OTHER SYSTEMIC FUNGICIDES. Powdery mildew is a serious disease of squash and cantaloupe grown in Florida. 1. What sets it apart from others is the ratio of both mono and di potassium phosphite in the formulation.

Phosphite salts can be used as a biodegradable fungicide to protect plants against Phytophthora dieback. Jackson, T.J., T. Burgess, I. Colquhoun, G.E.S. Chemical Group . These scientists were screening various chemicals for fungicidal properties when they discovered that phosphonate salts were effective in controlling diseases caused by a group of fungi known as the oomycetes (Phytophthora, Plasmopara, Pythium, and others). In greenhouse experiments, seedlings of Persea indica, an avocado relative, planted into soil naturally infested with Phytophthora cinnamomi did not develop root rot when treated with a foliar spray or soil drench of potassium phosphonate or fosetyl-aluminum (trade name = Aliette®). Potassium phosphonate was prepared by adding potassium hydroxide to phosphorous acid in water. 2000. Others, with ingredients that are virtually identical to the fungicides, are sold as fertilizers. The term phosphonic acid is often used synonymously with phosphorous acid. Validated by Experts, Validated by Users, Non-Validated, Removed by Users.

The reliable endpoints concluded as being appropriate for use in regulatory risk assessment, derived from the available studies and literature in the dossier peer reviewed, are presented. Phosphate (HPO4; H2PO4-) is taken up by plants and incorporated into cells where it forms an important energy-yielding molecule (ATP) and structural components of cell membranes and DNA. Monopotassium phosphate, a product of LidoChem, Inc., Hazlet, NJ, was reported to have some control of powdery mildew on grape in … To date, we are not aware of any confirmed reports of pathogen resistance to phosphonate fungicides in turfgrass (although phosphonate-resistant mutants of Pythium aphanidermatum have been induced in a laboratory) (14).

Nutrol (potassium dihydrogen phosphate): Protectant fungicide for powdery mildew. Houser, and H.Cole, Jr. 1983. Potassium phosphite protected against tuber blight as well as the best fungicide. Nevertheless, a recent report from California suggests that sensitivity to phosphonate fungicides was compromised in populations of Bremia lactucae (causal agent of lettuce downy mildew) treated repeatedly with phosphonate fungicides and fertilizers (3). Because of this unique property, phosphonates are viewed as excellent fungicides for controlling root rot diseases such as Pythium root rot and dysfunction caused by various Pythium species (5, 7). Potassium-phosphonate - Systemic Fungicide Ask Price With the aid of our experienced professionals, we are engaged in manufacturing and supplying Potassium-Phosphonate. Differences in turf quality became apparent in week 10 of the study, when high temperatures and humidity caused a decline in the untreated and potassium phosphate plots, while potassium phosphite plots showed improved quality. Accumulation of these compounds is thought to divert ATP from other metabolic pathways, resulting in a decrease in fungal growth (12).
