matter which can putrefy and release gasses like methane and ammonia that are toxic to plants. In soils lactic acid has the ability to suppress disease-in- ducing microorganisms including the mold Fusarium, which occur in continuous cropping programs. Under normal circumstances, species such as Fusarium weakens crop plants, exposing the plants to diseases and increased pest populations such as pathogenic nematodes. The use of LABs reduces pathogenic nematode populations and controls propagation and the spread of Fusarium, thereby creating a better en- vironment for crop growth. In soils, these probiotic microbes co-exist with other benefi cial fungi such as mycorrhizae that are known to attack several pathogenic fungi including fusarium, and also become food themselves to other organisms such as worms. Not only are the organic acids effective as pathogen controls, so are the bacte- riocins that are produced. Bacteriocins are specially designed enzymes that will attack pathogenic organ- isms, helping the LABs change the environment to es- tablish them. These are just a few reasons why LABs are considered the front line of defense for probiotic farmers. LABs can be mixed in water and some fertilizer and applied directly to soils as well as sprayed on plants throughout the growing cycle. It is best to apply a probiotic on a regular schedule. For instance, spray once per week throughout the growing season and run in irrigation once per week. For best results on spraying, mix with a sticker/spreader such as cal- cium lignosulfonate.
