Powdery mildew (PM) is a very serious disease affecting glasshousegrown roses and tomatoes in the Netherlands Control is limited because of resistance to existing fungicides Anhydrous milk fat (AMF) and soybean oil (SBO) emulsions were evaluated for control of PM in roses and tomatoes Both AMF (14 g/litre) and SBO (14 g/litre) provided powdery mildew control on rose leaves and blooms that was significantly better (P

Powdery mildew (PM) is one of the most serious global diseases of apples roses cucurbits grapes and cereals The potential of anhydrous milk fat (AMF) and soybean oil (SBO) formulations to control apple PM (caused by Podosphaera leucotricha) on the apple cultivar Royal Gala was investigated Potted seedlings in a glasshouse were left unsprayed or subjected to weekly sprays of AMF SBO fungicide (sulphur as Kumulus DF) or water During 67 weeks of treatment the AMF and SBO formulations significantly reduced PM to

Powdery mildew (PM) is a serious fungal disease of a wide range of horticultural crops and can adversely affect crop yield and quality Anhydrous milk fat (AMF) and soybean oil (SBO) emulsions were evaluated for control of PM (Sphaerotheca pannosa var rosae) on potted rose plants (Rosa L sp Splendid Surprise and Sahara) maintained in a controlled environment Foliage was sprayed weekly with AMF (07 w/v) SBO (2 w/v) fungicide (Supershield 1 v/v) water or left unsprayed PM infection increased to 100 leaf area in water and unsprayed control plants over 6 weeks The fungicide reduced infection to a severity rating of 5 (>40 leaf area infection) The AMF and SBO treatments gave significantly better disease control (P

Powdery mildew is a major cause of damage to squash plants. Anhydrous milk fat (AMF) or soybean oil (SBO) may be effective at treating this disease but these active ingredients must be mixed with an emulsifier to enable even distribution and suspension of fat globules, and an antioxidant to prevent rancidity. The overall formulation may affect disease control efficacy, leaf health and product stability. The effect of different emulsifiers and antioxidants on emulsion stability, odour and shelf-life of AMF and SBO bio-fungicides was tested in laboratory assays, and on powdery mildew disease control efficacy and leaf health on glasshouse-grown squash plants. Both AMF and SBO formulations including a polyglycerol ester emulsifier (Grindsted® PGE 20 Veg) resulted in the best emulsion stability, disease control and leaf health. None of the antioxidants tested significantly affected on disease control efficacy in AMF formulations, but SBO formulations containing vitamin E as the antioxidant provided the best disease control efficacy and emulsion stability.
