it has been shown that seedlings infected with "a. strictum" have high mortality rates. it would be agriculturally significant to identify biological control agents for this fungus. aerial parts of "cymbopogon schoenanthus", "hyptis spicigera", "lantana camara" and "ocimum americanum" were collected and air-dried for four days. after drying the plants, essential oils were extracted from the materials. a variety of seeds inoculated with fungi, some cohorts with "a. strictum". the oils were applied to the infected seeds. after allowing seedlings to develop, it was found that the oils in combination inhibited "a. strictum" mycelial growth significantly.
