“…Worldwide, an annual increase of 10% in the use of bio-pesticides has been estimated and among them, approximately 90% formulations are derived from Bacillus thuringiensis (Bt) (Kumar and Singh 2015;Osman et al 2015). However, there is a great potential to look for the indigenous strains and isolates of Bt and characterize their pathogenicity and toxicity against insect pest species (Sree and Varma 2015).…”

“…In the United States (US) market, more than 200 products are available, compared to 60 analogous products in the European Union (EU) market [6]. Although biopesticide use at a global scale is increasing by almost 10% every year [6], it appears that the global market must increase further in the future if these pesticides are to play a visible role in substituting for chemical pesticides and reducing the current over-reliance on them. It should be noted, however, that biopesticides are assessed in the EU by the same regulations used for the assessment of synthetic active substances, and this situation required several new provisions in the current legislation, as well as the preparation of new guidelines facilitating the registration of prospective biopesticide products [9].…”

“…Almost 90% of the microbial biopesticides currently available on the market are derived from only one entomopathogenic bacterium, i.e., Bacillus thuringiensis or Bt [6]. Currently, biopesticides comprise a small share of the total crop protection market globally, with a value of about $3 billion worldwide, accounting for just 5% of the total crop protection market [7,8].…”

Abstract:Biopesticides have attracted attention in pest management in recent decades, and have long been promoted as prospective alternatives to synthetic pesticides. Biopesticides have also attracted great interest in the international research community, with a significant increase in the number of publications devoted to the subject. Recently, new substances, like strains of the fungus Talaromyces flavus SAY-Y-94-01, extracts of the plant Clitoria ternatea (butterfly pea), products of the fungus Trichoderma harzianum, products of the bacterium Bacillus thuringiensis var. tenebrionis strain Xd3 (Btt-Xd3), the alkaloid compound oxymatrine, fermentation products of the bacterium Lactobacillus casei strain LPT-111, stilbenes accumulated in grape canes, and olive mill wastes, have been reported in the literature as promising compounds for use as biopesticides, but more field research is required to assess the effects on specific pest problems under diverse cropping systems. Nevertheless, biopesticides have not yet reached the desired level of use, whereby they could displace the dominance of chemical pesticides, given that the commercialization of new products in the market is lagging behind. Currently, biopesticides comprise a small share of the total crop protection market globally, with a value of about $3 billion worldwide, accounting for just 5% of the total crop protection market. Fewer biopesticide-active substances are registered in the European Union (EU) than in the United States, India, Brazil, or China, due to long and complex registration processes in the EU, which follow the model for the registration of conventional pesticides. Nanoformulations and microencapsulation technologies can improve the stability and residual action of biopesticide products, and this could increase their field use. Regulations that promote registration of low-risk compounds with the provision of incentives could also facilitate commercialization and availability of biopesticides in the market.

PGPR‐mediated induction of systemic resistance and physiochemical alterations in plants against the pathogens: Current perspectives

et al. 2020

Plant growth‐promoting rhizobacteria (PGPR) are diverse groups of plant‐associated microorganisms, which can reduce the severity or incidence of disease during antagonism among bacteria and soil‐borne pathogens, as well as by influencing a systemic resistance to elicit defense response in host plants. An amalgamation of various strains of PGPR has improved the efficacy by enhancing the systemic resistance opposed to various pathogens affecting the crop. Many PGPR used with seed treatment causes structural improvement of the cell wall and physiological/biochemical changes leading to the synthesis of proteins, peptides, and chemicals occupied in plant defense mechanisms. The major determinants of PGPR‐mediated induced systemic resistance (ISR) are lipopolysaccharides, lipopeptides, siderophores, pyocyanin, antibiotics 2,4‐diacetylphoroglucinol, the volatile 2,3‐butanediol, N‐alkylated benzylamine, and iron‐regulated compounds. Many PGPR inoculants have been commercialized and these inoculants consequently aid in the improvement of crop growth yield and provide effective reinforcement to the crop from disease, whereas other inoculants are used as biofertilizers for native as well as crops growing at diverse extreme habitat and exhibit multifunctional plant growth‐promoting attributes. A number of applications of PGPR formulation are needed to maintain the resistance levels in crop plants. Several microarray‐based studies have been done to identify the genes, which are associated with PGPR‐induced systemic resistance. Identification of these genes associated with ISR‐mediating disease suppression and biochemical changes in the crop plant is one of the essential steps in understanding the disease resistance mechanisms in crops. Therefore, in this review, we discuss the PGPR‐mediated innovative methods, focusing on the mode of action of compounds authorized that may be significant in the development contributing to enhance plant growth, disease resistance, and serve as an efficient bioinoculants for sustainable agriculture. The review also highlights current research progress in this field with a special emphasis on challenges, limitations, and their environmental and economic advantages.
