Summary 

Gliocladium catenulatum strain J1446 is a naturally occurring widespread fungus that can be 

used to control various fungal diseases in food and non-food crops, indoors and outdoors. 

The fungus appears to have no adverse effects on humans or the environment. 

I. Description of the Active Ingredient 

Gliocladium catenulatum strain J1446 is a soil fungus that can be readily grown in the 

laboratory. It feeds on dead and decaying matter. Researchers believe G. 

catenulatum secretes a chemical that inhibits the growth of other fungi. It does not 

appear to produce any toxins or antibiotics. 

II. Use Sites, Target Pests, and Application Methods 

Use Sites: G. catenulatum strain J1446 is approved for use indoors and 

outdoors. It can be used on a wide variety of vegetables, herbs and spices. It 

can also be used on turf, ornamentals, and on tree and shrub seedlings. 

Target Pests: Fungi that cause damping off, seed rot, root and stem rot, and 

wilt diseases. 

Application Methods: G. catenulatum is sold as a powder that can be 

incorporated into soil. When mixed with water, G. catenulatum can be sprayed 

on foliage or made into a dipping solution for cuttings and bulbs. It is generally 

applied when plants are sown, potted or transplanted; it is reapplied a few 

weeks later when the plants have emerged. 

III. Assessing Risks to Human Health 

No harmful health effects to humans are expected from use of G. catenulatum.

Appropriate tests found no evidence to suggest that the fungus is toxic or infectious 

to humans. The fungus is ubiquitous in the environment, and people are normally 

exposed to it. It is unlikely that the approved uses would noticeably increase human 

exposure. 

IV. Assessing Risks to the Environment 

Pesticide products containing G. catenulatum are not likely to pose a risk to the 

environment or to any organisms except target fungi. G. catenulatum occurs 

worldwide in many soil types. No adverse effects on the environment have been 

reported. 

V. Regulatory Information 

G. catenulatum strain J1446 was registered (licensed for sale) in July 1998 as a 

pesticide active ingredient. As of February 2002, PRIMASTOP Biofungicide was the 

only approved product. 

On February 1, 2002, outdoor and turf use sites were approved by EPA and added to 

the label.
