How to cite this article. Influence of fungi on cotton seed deterioration prior to harvest. Notices of North American fungi. Microbial control is receiving more attention, since these alternative tactics, compared to chemical control methods, are energy saving, non polluting, ecologically sound and sustainable. All the seed coats from the both the exposure periods, but none of the corresponding embryos, yielded F.

Mycoflora of cotton seed from the Southern United Fusariim On the other hand, the exposure for 48 h resulted in appreciable seedling emergence loss and seedling damage, even though cusarium fungus had not reached the embryonic tissues. 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.

This novel fungus can be well incorporated as a viable tactics into the integrated management programmes of crop pests. To collect the conidia, the culture plates were flooded with 10 ml of water, and the conidia were dislodged using a soft brush. A paper-thrips-paper sandwich method for thrips and detached-leaf bioassay method for mites were used.

Cottonseeds were inoculated by spraying 20 ml of the suspension on g seeds in a laboratory scale rotatory seed treater. These seeds when planted in autoclaved sand, emerged normally and no disease symptoms developed on the seedlings, which indicated that the externally seedborne inoculum of F.

Influence of internal seedborne Fusarium semitectum on cotton seedlings. More Spanish version Dr. The intensity of the fungal growth indicates higher inoculum in the seed sekitectum, which however could not be quantified. 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 strong winds or heavy capsule load thus affecting total yield.

In many cases the shedding of seed coat was delayed, which remained attached to the primary leaves resulting in a extensive reddish brown lesion on the leaf leading to localized dry rot.

Isolations were made from the some of the randomly picked non-emerged seeds, and also from the lesions appearing on any part of the emerged seedlings. Even when internally seedborne, the degree of damage appears to be related to the quantity fisarium 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.

Seedling emergence testes in autoclaved sand showed no correlation between the proportion of F.
