“…Examples of antibiotics are iturin A and surfactin (effective in controlling Botrytis cinerea and R. solani), bacillomycin D (Aspergillus flavus), and mycosubtilin (Pythium aphanidermatum). Hydrogen cyanide, aldehydes, alcohols, chitons, and sulfides represent volatile compounds produced by the bacterium, causing structural deformation in several phytopathogenic fungi (Maheshwari 2013). Phosphites yielded satisfactory results at higher product concentrations, highlighting copper and manganese phosphites.…”

“…Remuska and Dalla Pria (2007) reported a similar finding in controlling the same fungus. Maheshwari (2013) stated that B. thuringiensis, like other bacteria of the same genus, produces the zwittermicin A antibiotic and toxins, such as butyric acid, cyanide, exotoxins, and hydrogen sulfate but without the same effectiveness in controlling phytopathogenic fungi.…”

Products that activate plant defense mechanisms, such as white mold, may increase the disease control spectrum in canola crops as an alternative to chemical control for disease management, aiming at lower environmental impacts and selection pressure on pathogens. This study evaluated Sclerotinia sclerotiorum control and resistance induction in canola crops with alternative products. In vitro and detached leaf experiments were conducted in a laboratory, and in vivo experiments occurred in a greenhouse. High Roots®; V6®; Maxi Flor®; Wert Plus®; potassium, manganese, and copper phosphites; manganese; procymidone fungicide; and Ascophyllum nodosum, Bacillus subtilis, and Bacillus thuringiensis extracts assessed S. sclerotiorum mycelial growth in vitro in detached leaves, white mold severity in a greenhouse, and enzymatic analysis in leaf tissues. The last two experiments also received the acibenzolar-S-methyl and Trichoderma asperellum treatments. S. sclerotiorum mycelial growth showed 100% inhibition under B. subtilis and Wert Plus® at 1000 ppm and procymidone at 100 and 1000 ppm in vitro. The procymidone and B. subtilis treatments in detached leaves inhibited 100% of fungus growth. The greenhouse experiments with lower severity were procymidone, copper phosphite, B. thuringiensis, B. subtilis, manganese phosphite, potassium phosphite, High Roots®, and V6®. Higher peroxidase enzyme activity occurred in plants treated with acibenzolar-S-methyl, copper phosphite, and fungicide 48 hours after pathogen inoculation. The polyphenol oxidase enzyme did not show activity. Alternative products were responsive and may aid the chemical control of white mold in canola crops.

“…Several species of PPNs that feed on roots (root knot, cyst, reniform, lesion, dagger nematodes), stems and leaves ( Ditylenchus , Aphelenchoides, Bursaphelenchus ) are widespread in nature and represent the most harmful parasites of plants [ 4 , 27 ]. The effect of bacteria on PPNs population density is particularly interesting in the cases of genera Bacillus , Pseudomonas and Serratia which have shown the highest efficacy as PGPB in their biological control for the last two decades [ 20 , 28 , 29 ].…”

Phytoparasitic nematodes cause severe damage and yield losses to numerous agricultural crops. Considering the revision of the EU legislation on the use of pesticides on agricultural crops, control strategies with low environmental impact are required. The approach based on the use of bacteria seems particularly promising as it also helps to reduce the applied amounts of chemicals and stabilize ecological changes. This paper gives an overview of the main types of bacteria that can be used as biological control agents against plant parasitic nematodes and their interrelationships with plants and other organisms. Many experiments have given positive results of phytoparasitic nematode control by bacteria, showing possible prospects for their application. In vitro, greenhouse and field experiments have shown that bacteria can regulate the development of ecto- and endoparasitic nematodes by different modes of action. Triggering the induction of plant defense mechanisms by bacteria is seen as the optimum tool because the efficacy of bacterial treatment can be higher than that of chemical pesticides or at least close to it. Moreover, bacterial application produces additional positive effects on growth stimulation, raises yields and suppresses other pathogenic microorganisms. Commercial formulations, both as single bacterial strains and bacterial complexes, are examined.

“…Nematophagous bacteria are also ubiquitous and have a wide host population [183], so they have been used in the control of nematodes [184,185]. During their life processes, they produce antibiotics and toxins that inhibit nematode reproduction and survival, or directly cause nematode death via the lysis of their cell walls [186].…”

The last few years have witnessed the emergence of alternative measures to control plant parasitic nematodes (PPNs). We briefly reviewed the potential of compost and the direct or indirect roles of soil-dwelling organisms against PPNs. We compiled and assessed the most intensively researched factors of suppressivity. Municipal green waste (MGW) was identified and profiled. We found that compost, with or without beneficial microorganisms as biocontrol agents (BCAs) against PPNs, were shown to have mechanisms for the control of plant parasitic nematodes. Compost supports a diverse microbiome, introduces and enhances populations of antagonistic microorganisms, releases nematicidal compounds, increases the tolerance and resistance of plants, and encourages the establishment of a “soil environment” that is unsuitable for PPNs. Our compilation of recent papers reveals that while the scope of research on compost and BCAs is extensive, the role of MGW-based compost (MGWC) in the control of PPNs has been given less attention. We conclude that the most environmentally friendly and long-term, sustainable form of PPN control is to encourage and enhance the soil microbiome. MGW is a valuable resource material produced in significant amounts worldwide. More studies are suggested on the use of MGWC, because it has a considerable potential to create and maintain soil suppressivity against PPNs. To expand knowledge, future research directions shall include trials investigating MGWC, inoculated with BCAs.
