The Bacillus firmus<\/strong><\/em> is an aerobic Gram-positive family bacterium Bacillaceae<\/em>order Bacillales<\/em>phylum Firmicutes<\/em>. Like many bacteria of this genus, for example the Bacillus thuringiensis<\/u><\/em> and the Bacillus subtilis<\/u><\/em>also the Bacillus firmus<\/em> it is ubiquitous and occurs naturally in the soil, rhizosphere and aquatic environment.<\/span> The interest in it is due to its nematodicidal action and the bioprotective effect it has on crops. THE plant parasitic nematodes<\/u>in fact, they create serious problems for crops and are very difficult to combat by being active in the soil.<\/p>\n Let’s see, therefore, its biological action and how to exploit it in the phytosanitary defense of vegetables sensitive to nematodes.<\/span><\/span><\/span><\/p>
