Isolates of the endophytic Leptostroma anamorph of Lophodermium pinastri were collected from needles of Pinus resinosa (red pine) at three locations in Eastern Canada. The DNA of 69 isolates which were morphologically identical was subjected to RFLP

Endophytic fungi were isolated from black spruce (Picea mariana (Mill.) BSP) dormant buds and needles of four age-classes. Only one isolate was obtained from 400 buds. A total of 914 isolates were obtained from the needles. With increasing needle age

The bioactive constituents of extracts of three strains of balsam fir endophytic fungi, reported to cause reduced growth rate and mortality of spruce budworm larvae, have been isolated and characterized. Bioassay-directed fractionation has resulted i

Endophytic fungi were isolated from the interiors of surface-sterilized needles of balsam fir (Abies balsamea) and red spruce (Picea rubens) in New Brunswick, Canada. Four different fungi were isolated frequently. One species, designated X-W, was iso

The production of metabolites which are toxic to the spruce budworm by endophytic fungi in balsam fir and red spruce needles was investigated. From a collection of ca 900, 94 strains were selected at random and grown in liquid culture. Five strains p

In bio-assay tests ether extracts of the roots and of the stalks of both resistant and susceptible corn inbreds inhibited the growth of Fusarium moniliforme Sheld. and Gibberella zeae (Schw.) Petch, the level of inhibition varying over the season. Ho

Examination of selected corn inbreds in a disease nursery revealed that root rot and stalk rot are successive phases of a disease which begins in the roots and later spreads into the stalk. Stalk rot first appeared on the inbred of early maturity, la
