“…Furthermore, a combination of LS11 strain of the yeast Rhodotorula kratochvilovae and B. subtilis strain QST 713, and a concentration of 25% of cyprodinium, cyprodinil, and boscalid sufficiently protected the treated peach with minimum chemical residues left in the peach juice [ 46 ]. Therefore, an effective combination of different biological and chemical methods requires a good understanding of the ecology of antagonists [ 47 ]. Understanding how to manage postharvest diseases cost-effectively and reliably and how different alternative technologies affects the host and the microorganism community is becoming more crucial in successful management programs.…”

Simultaneous treatment with antagonistic bacteria Bacillus amylolquefaciens (SF14), Alcaligenes faecalis (ACBC1), and the food additive sodium bicarbonate (SBC) to control post-harvest brown rot disease caused by Monilinia fructigena, and their effect on the post-harvest quality of nectarines were evaluated. Four concentrations of SBC (0.5, 2, 3.5, and 5%) were tested. Results showed that bacterial antagonists displayed remarkable compatibility with different concentrations of SBC and that their viability was not affected. The results obtained in vitro and in vivo bioassays showed a strong inhibitory effect of all treatments. The combination of each bacterial antagonist with SBC revealed a significant improvement in their biocontrol efficacies. The inhibition rates of mycelial growth ranged from 60.97 to 100%. These results also indicated that bacterial antagonists (SF14 or ACBC1) used at 1 × 108 CFU/ mL in combination with 2, 3.5, or 5% SBC significantly improved the control of M. fructigina by inhibiting the germination of spores. Interestingly, disease incidence and lesion diameter in fruits treated with SF14, ACBC1 alone, or in combination with SBC were significantly lower than those in the untreated fruits. In vivo results showed a significant reduction in disease severity ranging from 9.27 to 64.83% compared to the untreated control, while maintaining the appearance, firmness, total soluble solids (TSS), and titratable acidity (TA) of fruits. These results suggested that the improved disease control by the two antagonistic bacteria was more likely due to the additional inhibitory effects of SBC on the mycelial growth and spore germination of the pathogenic fungus. Overall, the combination of both bacteria with SBC provided better control of brown rot disease. Therefore, a mixture of different management strategies can effectively control brown rot decay on fruits.

“…At the same time, it could be able to attain biocontrol efficacy and consistency on par with synthetic chemical pesticides. In addition, based on the literature, the time of beneficial microbial application has been examined [ 206 ]. Sare et al [ 206 ] proposed, for example, that shifting treatment at the blooming stage (to establish a “path dependency”) be investigated for future fruit and vegetable postharvest disease management.…”

Biological Control of Plant Pathogens: A Global Perspective

The increase in the world population has generated an important need for both quality and quantity agricultural products, which has led to a significant surge in the use of chemical pesticides to fight crop diseases. Consumers, however, have become very concerned in recent years over the side effects of chemical fungicides on human health and the environment. As a result, research into alternative solutions to protect crops has been imposed and attracted wide attention from researchers worldwide. Among these alternatives, biological controls through beneficial microorganisms have gained considerable importance, whilst several biological control agents (BCAs) have been screened, among them Bacillus, Pantoea, Streptomyces, Trichoderma, Clonostachys, Pseudomonas, Burkholderia, and certain yeasts. At present, biopesticide products have been developed and marketed either to fight leaf diseases, root diseases, or fruit storage diseases. However, no positive correlation has been observed between the number of screened BCAs and available marketed products. Therefore, this review emphasizes the development of biofungicides products from screening to marketing and the problems that hinder their development. Finally, particular attention was given to the gaps observed in this sector and factors that hamper its development, particularly in terms of efficacy and legislation procedures.

“…The rise of biotechnology in the last decade has made biocontrol one of the most studied sustainable alternatives in reducing postharvest diseases by using antagonistic microorganisms against phytopathogens [14,15], which is considered a viable alternative to synthetic fungicides [16]. Among the microorganisms, yeasts stand out for their antagonistic capacity, for example, they have certain characteristics, such as genetic stability, Plants 2021, 10, 2641 2 of 12 efficacy at low concentrations; control towards different phytopathogens [17]; simple nutritional requirements; survival under adverse environmental conditions; compatibility with other chemical and physical treatments; resistance to synthetic fungicides; and absence of pathogenicity towards the host [18,19].…”

Postharvest diseases of fruits caused by phytopathogens cause losses up to 50% of global production. Phytopathogens control is performed with synthetic fungicides, but the application causes environmental contamination problems and human and animal health in addition to generating resistance. Yeasts are antagonist microorganisms that have been used in the last years as biocontrol agents and in sustainable postharvest disease management in fruits. Yeast application for biocontrol of phytopathogens has been an effective action worldwide. This review explores the sustainable use of yeasts in each continent, the main antagonistic mechanisms towards phytopathogens, their relationship with OMIC sciences, and patents at the world level that involve yeast-based-products for their biocontrol.
