“…A good example of Bacillus spp. as a bioagent was described by Zhu et al (2021). The group found that B. velezensis either directly or indirectly defends the plant against rice blast by generating antibiotics against plant pathogenic bacteria and triggering a rice PAMPtriggered immune (PTI) response.…”

Grain yields of rice (Oryza sativa) are affected globally by rice blast (Magnaporthe oryzae). The main objective of this study was to identify isolates of rhizobacterial antagonists of M. oryzae (BRM10781) and screen the most effective isolates for suppressing rice blast under greenhouse conditions. Two assays (E1 and E2) were performed with 22 treatments in a completely randomized design with three replicates. E1 investigated in vitro antagonism between 21 isolates and M. oryzae under laboratory conditions. The E2 experiments were conducted under greenhouse conditions, with rice cultivar BRS Primavera seeds in plastic trays containing 3 kg of fertilized soil. After 21 days, the rice leaves were spray-inoculated with a bacterial cell suspension (1 × 108 CFU) and M. oryzae (3 × 105 conidia.mL-1) or with water (absolute control). Seven isolates, Serratia marcescens (BRM65918, BRM65923, BRM65926, and BRM63532), Bacillus cereus (BRM65919), Stenotrophomonas nitritireducens (BRM65917), and Priestia megaterium (BRM65929), reduced radial growth of M. oryzae colonies from 80.26 to 77.33%. The best leaf blast severity reducers were Pseudomonas nitroreducens (BRM32112), B. thuringiensis (BRM65928), P. megaterium (BRM65916), S. marcescens (BRM65918), S. nematodiphila (BRM63522), and Enterobacter hormaechei (BRM65925), varying from 97 to 95% respectively. The isolate BRM65918 (S. marcescens) showed the best efficiency for both antagonism and disease suppression, indicating its potential as a bioproduct for the biocontrol of rice blast in rice plants.

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.

Reducing agricultural production inputs while maintaining a lucrative yield of high-quality goods is becoming more and more necessary as a result of the global sustainability agenda. Plant diseases pose a significant threat to productivity and product quality, yet many times there are no adequate measures available to control them. Consequently, research on substitute methods of crop protection has been mandated and has garnered significant interest from scholars around. A number of biological control agents (BCAs), including Bacillus, Pantoea, Streptomyces, Trichoderma, Clonostachys, Pseudomonas, Burkholderia, and specific yeasts, have been screened. Of these alternatives, biological controls through beneficial microorganisms have gained significant importance. BCAs, at the very least, support other sustainable disease management strategies like disease resistance and offer chances to control illnesses for whom alternative strategies are unfeasible or unobtainable. It is reasonable to anticipate that BCAs will be used more often to manage agricultural diseases in environmentally friendly ways.
