“…Anhydrous milk fat (AMF) and soybean oil (SBO) emulsions were evaluated for control of PM (S. pannosa var. rosae) on potted rose plants maintained in a controlled environment (Chee et al, 2011). Foliage was sprayed weekly with AMF (0.7% w/v), SBO (2% w/v).…”

Bupirimate 25% Emulsifiable concentrate (EC) was evaluated for efficacy on Sphaerotheca pannosa, the causal agent of rose powdery mildew in vivo. In this experiment Bupirimate 25% EC 6 ml/L and 4 ml/L effectively reduced the powdery mildew infection over rest of the treatments and improved the flower yield. Moreover, application of Bupirimate 25% EC at the doses of 2, 4 and 6 ml/L and even at higher dose 8 ml/L did not show any phyto-toxic symptoms on rose plant. Thus, Bupirimate 25% EC may be considered as compared to other fungicides.

“…Regarding cow milk, it has been studied by many researchers (Bettiol, 1999;Chee et al, 2011;, Choudhary et al, 2018Crisp, 2006;DeBacco, 2011;Ferrandino and Smith, 2007;Guzmán-Plazola et al, 2011;Keinath and DuBose, 2012;McMillan and Vendrame, 2006;Nam et al, 2005;Shah, 2000). Most of the plant protection activity is due to its antifungal properties (Mudgil et al, 2022;Kumar and Kumar, 2021;Sudisha et al, 2011;Wurms and Chee, 2011).…”

The study was conducted during spring and summer 2022 at Mare Savin garden centre (Trappes, France) to confirm plant protection properties of some dairy products. Indeed, for crop protection, the search for new non-chemical fungicides useful, durable, affordable and efficient as active substances (a.s.). These suitable products, especially from natural origin called BioControl Agents (BCA) are acceptable to civil society (i.e., low-concern profile, and absence of residues of concern) are of paramount importance as the number of chemical solutions has drastically decreased in recent years. When natural substances from the plant origin are plethoric in literature and some are approved as Plant Protection Product (PPP), natural substances from the animal origin repertoire are sparsely represented in PPP a.s., but lately a few substances have obtained a European Union (EU) active substance approval (i.e. sheep fat, blood meal, fish oil, chitosan hydrochloride from crab shell). Dairy products may also exhibit crop protection properties like whey and cow milk are two of these new BCAs. The corresponding applications under EU PPP regulation (EC) n° 1107/2009 were granted as basic substance according Article 23, respectively in 2016 for whey and 2020 for cow milk for protection of vegetable against mildew and agricultural tools disinfection. These basic substances are approved for an unlimited period of time with no Market Authorisation, for all Europe without zone or Member State consideration, and with no Maximum Residue Limits (MRL). Later, an extension of use for vineyards protection against diseases was granted for whey in 2021.

“…Disease control offered by mineral oils, along with oils derived from plants and animals, is also very durable [19,20]. Research to date has shown that NP1 and NP2 were highly effective against various PM pathogens on different crops in laboratory and glasshouse experiments [21][22][23][24][25]. However, these environments were artificially controlled, and product efficacy in a highly variable field environment was unknown, hence the need for the current research.…”

Synthetic controls of crop pathogens are increasingly associated with harm to the environment and human health, and pathogen resistance. Pesticide residues in crops can also act as non-tariff trade barriers. There is therefore a strong imperative to develop biologically based and natural product (NP) biofungicides as more sustainable alternatives for crop pathogen control. We demonstrate the field efficacy, over multiple seasons, of NP biofungicides, NP1 (based on anhydrous milk fat) and NP2 (based on soybean oil), on two major diseases of winegrapes—Botrytis bunch rot (Botrytis) and powdery mildew (PM). The NPs were integrated into a season-long integrated disease management programme that has produced chemical-residue-free wines. Efficacies for Botrytis control on three different varieties were: 63–97% on Chardonnay, 0–96% for Sauvignon Blanc and 46–58% on Riesling; with 65–98% PM control on Chardonnay and Riesling. NP2 exhibited the significant control of Botrytis latent infections, making it a viable alternative to mid-season synthetic fungicides. Disease control was significantly better than the untreated control and usually as efficacious as the synthetic fungicide treatment(s). Yields and wine quality in NP-treated crops were normally equivalent to those in the synthetic fungicide treatments. The results indicate that NP-mediated disease control of Botrytis and powdery mildew can be obtained in the vineyard, without synthetic fungicide input.
