A NDVI value closer to 0 indicates less healthy plants (or more bare ground).

Although in most cases there were no statistically significant differences in the value of the crop between the conventional/biofungicide programs and the full conventional program, the numerical value of the marketable crop ranged from being slightly higher (LifeGard alternated with conventional fungicides on Long Island) to lower (all other biofungicide treatments). If youve tried this, wed love to hear how it worked for you! Some biocontrol agents areknown to trigger these mechanisms, and in the case of induced resistance, hostplants are purposely inoculated with this agent in an effort to trigger theresistant response. It is the involvement of the use ofbeneficial microorganisms, such as specialized fungi and bacteria, to attackand control plant pathogens and the diseases they cause.
