“…Treatments containing whole milk powder and whey proteins gave variable disease control depending on the concentration (g/L) of the active ingredient, purity of the product, and the nature of co-ingredients, and were associated with sooty mould growth in the presence of heavy whitefly populations. Savocchia et al (2011) also observed that PM disease control efficacy of whole milk and whey protein was inconsistent and diminished over the course of two seasons' trial work on field-grown grapes. They concluded that these products were most suited to use on grape cultivars that were less susceptible to PM such as 'Cabernet Sauvignon' and 'Shiraz' and was best suited to conditions of low disease pressure.…”

“…Milk products have been used informally as bio-fungicides for many years with varying success (Bettiol 1999;Ferrandino & Smith 2007;Savocchia et al 2011;Martins et al 2016), but have not been commercialised, due to problems such as milk spoilage, handling difficulties, poor durability of control, and unwanted growth of non-target organisms. Milk is a nutritionally complex mixture and some of its components have antimicrobial activity, such as whey protein (Crisp et al 2006;Bettiol et al 2008) and fats (Horincar & Bahrim 2017).…”

Powdery mildew (PM) infection of cucurbits is a major problem facing commercial New Zealand growers. Resistance to demethylation inhibitor fungicides is widespread so, there is a demand for new-generation bio-fungicides that can provide durable control alternatives in both conventional and organic systems. A wide range of milk products, plant and animal fats/oils, and natural plant elicitors were tested for their ability to control PM on squash and zucchini plants in a series of four glasshouse trials. The most promising product tested was anhydrous milk fat (AMF), in formulation with an emulsifier (Alanate 191™ or Panodan® AL10), an antioxidant (Grindox 122™) and/or other products (Synertrol Horti oil). These treatments were as effective as commercial fungicides in controlling PM, but there were significant issues with plant health. Future work will focus on reducing concentrations of the active ingredient to produce an effective formulation that is not detrimental to plant health. Soybean oil, coconut fat and olive oil formulations with Panodan® AL10 and Grindox 122™ also gave effective PM control with minimal effect on plant health.

“…This study represents the first report of AMF being used to control powdery mildew, and the first report of the use of SBO against apple PM since 1993 (Northover & Schneider 1993). Savocchia et al (2011) evaluated milk and botanical oils for control of grapevine powdery mildew, but data from three seasons showed that these products provided relatively poor disease control on Chardonnay grapes. Although SBO has been used in trials to control PM in other crops, results have been variable (Northover & Schneider 1996;Jee et al 2009), probably because of differences in formulation.…”

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

“…Such diversified approaches to powdery mildew management may reduce the risk of causal organisms developing resistance to some fungicides (Erickson and Wilcox, 1997). Elemental sulfur is also commonly used to control powdery mildew in organic production systems because it works relatively well under low inoculum conditions early in the season and will help to reduce applications of more effective but more resistance-prone material later in the season during peak disease infection (Savocchia et al, 2011;Smith et al, 2014). When applied to tolerant vines, sulfur is a relatively inexpensive and effective complement to other fungicides for effective control and prevention of resistance (Bordelon et al, 2016).…”

Elemental sulfur is commonly applied for powdery mildew (Erysiphe necator) protection on winegrape (Vitis sp.). The product may be used in a diversified, integrated disease management system to help prevent fungicide resistance to products with other modes of action. Additionally, sulfur may be used as a control option in organic systems. Applications of sulfur have been known to cause phytotoxic injury to susceptible winegrape cultivars, particularly those stemming from fox grape (Vitis labrusca) parentage. To improve recommendations to producers in the northern Great Plains region of the United States, a comparison of injury incidence and severity, as well as effects on yield characteristics was undertaken for 13 regional cultivars exposed to three sulfur rates (0, 2.4, and 4.8 lb/acre a.i.) at a North Dakota State University Research Station near Absaraka, ND. Overall, four cultivars (Bluebell, Baltica, Sabrevois, and King of the North) of the 13 cultivars tested showed phytotoxic symptoms. Injury severity and incidence of these cultivars differed between years and across rates. ‘Bluebell’ showed consistent and severe sulfur injury symptoms. Injury to the other three susceptible cultivars tended to vary by the given environment, with King of the North generally showing the lowest injury response. Injury symptoms were not found to be associated with the overall yield or cluster weight. Results suggest that alternative spray programs that exclude sulfur-based fungicides should be recommended for ‘Bluebell’, ‘Baltica’, ‘Sabrevois’, and ‘King of the North’, whereas sulfur-based fungicides may be applied to ‘Alpenglow’, ‘ES 12-6-18’, ‘Frontenac’, ‘Frontenac Gris’, ‘La Crescent’, ‘Marquette’, ‘Somerset Seedless’, ‘St. Croix’, and ‘Valiant’. Observations on fruit ripening in 2014 suggest that future research is needed to determine if a reduction of fruit quality may occur in some seasons with repeated sulfur applications or with successive annual sulfur applications for susceptible cultivars if used in an organic production system.
