Summary

Bacillus mycoides is a common and ubiquitous soil organism. The isolate J has been isolated for experimental use as a fungicide to control Cercospora Leaf Spot on sugar beet leaves. No harm to humans or the environment is expected when used according to label directions. EPA has issued an Experimental Use Permit dated June 8, 2006 which is to expire on December 31, 2007.

  1. Description of the Active Ingredient

    2. OPP Chemical Code: 006516

    Bacillus mycoides is a naturally ubiquitous microorganism in the soil. Application of an isolate of this bacterium to the leaves of sugar beet foliage induces systemic resistance in the plant characterized by an oxidative burst and production of pathogenesis related proteins, but does not result in plant cell death or tissue necrosis. This microbial fungicide is applied, in an experimental program only, to control Cercospora Leaf Spot. The disease is prevalent in the northern states of Montana, Minnesota, and North Dakota.

  3. Assessing Risks to Human Health

    4. Given the common occurrence of Bacillus mycoides, the lack of adverse reports in the clinical literature relating to this organism, and the lack of mortality as well as the absence of overt signs of toxicity or pathogenicity reported in the course of animal tests, no harmful effects from the experimental use of Bacillus mycoides isolate J are expected to be experienced by humans using proper respiratory protection.

  4. Assessing Risks to the Environment

    5. Bacillus mycoides isolate J is an ubiquitous spore forming bacterium commonly found on plants, in soil, water, air and decomposing plant tissue. It is not known to be pathogenic or toxic to any environmental animal or plant species, with the possible exception of farmed channel catfish. B. mycoides is not known to produce any toxins, although several antibiotic substances are produced. During the course of the experimental project, the quantity of the product applied to foliage is small compared to the natural background levels of B. mycoides reported to occur in agricultural soils. Taking these factors into consideration, no significant or irreversible adverse effects on wildlife are anticipated in the course of this EUP, given its proposed limited duration and limited acreage.

  5. Regulatory Information

    6. Montana Microbial Products submitted to EPA an application, dated September 15, 2005, for an Experimental Use Permit. On June 8, 2006, EPA granted the Experimental Use Permit under Section 5 of the Federal Insecticide, Fungicide and Rodenticide Act to allow the use of the fungicide Bacillus mycoides Isolate J on the food crop sugar beets when applied to control Cercospora Leaf Spot (Cercospora beticola). A temporary exemption from the requirement of a tolerance, Pesticide Petition 5G6983, was published in the Federal Register on June 14, 2006. The temporary tolerance exemption will expire on December 31, 2007.
