To simulate internally seedborne inoculum, the fungus was cultivated on moisture restricting culture medium as described by Machado et al. For practical reasons we have decided not to translate all pages in several languages anymore because it was too heavy to maintain but some of the labels of the basic and advanced query pages are still available.

The fungus grown in cow dung for two weeks was used to assess the composting ability of E. After the each exposure period the seeds were removed from the culture and allowed to dry over a laboratory bench for 24 h. Lily Eurwilaichitr and Dr. To collect the conidia, the culture plates were flooded with 10 ml of water, and the conidia were dislodged using a soft brush.

During the routine analysis, using standard blotter test, of the several acid delinted seed samples received by our seed pathology laboratory, no fungal pathogen of known importance was generally detected, but majority of the samples usually yielded F. Plant Disease Reporter Although the occurrence of F. Pod rot, seed rot and root rot of snap and dry bean caused by Fusarium semitectum.

Even when internally seedborne, the degree of damage appears to be related to the quantity of inoculum present in the seed coat, since neither emergence rate nor appreciable seedling damage occurred if the seeds were exposed to the fungal colonization for only 24 h. Other fungal links Bibliography links General links Molecular links Specimens and strains links. Cottonseeds were inoculated by spraying 20 ml of the suspension on g seeds in a laboratory scale rotatory seed treater.

On the other hand, the exposure for 48 h resulted in appreciable seedling fusaruim loss and seedling damage, even though the fungus had not reached the embryonic tissues. All the seed coats from the both the exposure periods, but none of the corresponding embryos, yielded F. The continued root rot of post-seedling fusarlum also suggests that the damage may not be limited only to the reduced stand due semiectum poor emergence and seedling blight, but the seedborne inoculum can damage the growing plants, although the type of damage could not be ascertained at this stage.

Fusisporium pallidoroseum Cooke, Grevillea 6 Fusarium semitectum was found to be the major seed colonizing fungus in the commercial acid delinted cotton Gossypium hirsutum seed lots. Pairwise sequence alignments Polyphasic identifications.

The fungus did not cause mortality on larvae of lepidopteran insect pests and ladybird beetle Menochilus sexmaculatuspredatory mite Amblysius ovalis and larval parasitoid Goniozus nephantidis. Therefore the importance of F. Specimens semitevtum strains links: Specimen record 2.

Mulberry leaves sprayed with the fungal suspension were fed to larvae of B. The surviving seedlings continued to grow, but most of them succumbed to extensive dry root rot Figure 1Ewhich indicates that such plants may break or lodge under semitectuk winds or heavy capsule load thus affecting total yield.

Internally seedborne Fusarium semitectum and Semifectum sp. Microbial control is receiving more attention, since these alternative tactics, compared to chemical control methods, are energy saving, non polluting, ecologically sound and sustainable. The lesion expansion was slow and did not girdle the collar. The symptoms caused by the seedborne inoculum of F. Seedling emergence testes in autoclaved sand showed no correlation between the proportion of F. In many cases the shedding of seed coat was delayed, which remained attached to the primary leaves resulting in a extensive reddish fusaroum lesion on the leaf leading to localized dry rot.

The internally seedborne inoculum besides reducing seedling emergence, incited an array of symptoms on the emerged seedlings, which ranged from negative geotropism, leaf tearing, collar rot leading to dry root rot and seedling mortality.
