    Notes: Summary Mycoparasitic behaviour ofF. udum on two soil-inhabiting microfungi,Aspergillus luchuensis andSyncephalastrum racemosum, was studied in dual cultures.Fusarium udum coiled and penetrated the host fungi and formed chlamydospores inside their hyphae and reproductive structures. The vegetative hyphae ofA. luchuensis showed swellings due to diffusible toxic substances ofF. udum in the medium and formed vesicle-like structures. This is the first record of these fungi being hosts of the mycoparasiteF. udum.

    Effect of soil burning on microfungi (1977)
    Springer
    Plant and soil 47 (1977), S. 693-697 
    Details
    ISSN: 1573-5036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The qualitative and quantitative nature of microfungi in soil after burning was studied for seven months. The numbers of fungal species and their colonies in soil were reduced immediately after burning but returned to their normal state after about a couple of months. Species of Aspergillus and Penicillium were the first to colonize the burnt soil. Trichoderma viride appeared after two months. Penicillium spp. decreased consistently with time whereas T. viride followed the reverse path. Several other species appeared in due course as and when ecological conditions became suitable for them. re]19760720

    Effect of cultival practices and soil treatments on incidence of wilt disease of pigeon pea (1981)

    Notes: Summary The incidence of wilt disease of pigeon pea (Cajanus cajan (L.) Millsp.) caused byFusarium udum under soil treatments with various substances was studied under field conditions. The disease incidence was highly suppressed under mixed cropping withCrotalaria medicaginea. Phygon XL was found to be the most effective fungicide to reduce the incidence of the disease. The incidence of wilt disease also decreased in case of soil amended with the leaves ofC. medicaginea. Wilt incidence increased in the soil amended with the roots of pigeon pea.

    Notes: Summary Trichoderma viride was found to be parasitic on three species of Aspergillus. The mycoparasitism was characterized by frequent coiling, penetration and hyphal growth of the parasite inside the conidiophores of Aspergillus. The volatile and non-volatile metabolites ofT. viride, more or less, inhibited radial growth of all the testAspergillus spp.

    Study of fungi on decaying leaves of Saccharum munja by differential washing technique (1976)
    Springer
    Plant and soil 44 (1976), S. 233-236

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary This study reports that the primary fungal colonizers of decaying leaves, which were rarely recorded with the last fungal colonizers in the pattern of succession in later stage of decaying, were persistent in dead tissues in the form of dormant mycelia and were unable to sporulate due to competition with last colonizers for nutrition and space in substrates. The presence of such fungi in suppressed and dormant condition in the sustrate is confirmed by transference of washed bits of leaves onto nutrient media which allowed them to grow and sporulate freely.

    Fungistatic activity of different Indian soils againstFusarium udum Butler (1981)

    Notes: Summary The fungistatic activity of different Indian soils againstF. udum, causing wilt disease of pigeon-pea, has been assessed in relation to soil pH and organic matter. Correlation co-efficient between soil characteristics and fungistasis has been calculated to evaluate relationship. High fungistatic activity was exhibited generally by the soils having low pH but high organic matter. The soils exhibiting high fungistatic activity againstF. udum have low incidence of wilt disease of pigeon-pea. There was no definite correlation between volatile and non-volatile fungistasis and, therefore, the origins of volatile and non-volatile fungistasis are different. In the usual biological limit pH had insignificant impact on fungistasis.

    Notes: Summary A urea and NPK-mixture at concentration of 5, 10 and 15 mg g−1 air dry litter stimulated microbial populations, microbial activity and rate of decomposition of the litter. The stimulation was more pronounced as the concentration of the fertilizers was increased. However, this trend was reverse after two months in case of urea except for bacterial population. Fewer fungal species were isolated from the fertilizer-treated litter, together with a certain degree of alteration in the composition of mycoflora.

    Notes: Summary Colony interactions and mycoparasitism betweenAcremonium furcatum and ten species of Aspergillus were studied in dual cultures. It was observed thatA. furcatum overgrew the colonies of all the ten species of Aspergillus studied. During the mycoparasitic interactions frequent coiling, penetration and growth of hyphae ofA. furcatum inside the conidiophores of six species of Aspergillus were observed.

    Studies on antagonism betweenFusarium udum Butler and root region microflora of pigeon-pea (1987)

    Notes: Abstract Antagonism betweenFusarium udum Butler causing wilt of pigeon-pea (Cajanus cajan (L.) Millsp.) and the saprophytic microflora of the root region of the host was studied with reference to colony interaction, hyphal interference, volatile and non-volatile metabolites and staling growth products. Studies were extended to screen potential antagonists against the wilt pathogen in soil. Aspergillus flavus, A. niger, A. terreus, Penicillium citrinum andMicromonospora globosa (an actinomycete) were antagonistic againstF. udum, whereas the pathogen parasitized and killedAspergillus luchuensis, Cunninghamella echinulata, Curvularia lunata, Mortierella subtilissima andSyncephalastrum racemosum. The pattern of growth of microorganisms on nutrient agar staled by rhizosphere soil inocula of healthy or wilted pigeon-pea plants was found to be different.F. udum colonized and grew on nutrient agar staled by the rhizosphere inoculum of the wilted plants upto 120h of incubation. However, it could not colonise and grow on the nutrient agar staled by rhizosphere microflora of healthy plants after 48h of incubation because of the presence of antagonists likeA. niger, A. flavus, A. terreus and a few species ofPenicillium in the soil inoculum. When pure cultures in soil ofF. udum was mixed with those of antagonists in different ratios,A. niger, A. flavus andM. globosa significantly suppressed the population ofF. udum, whereasA. terreus markedly reduced the population. When inoculated in soil, the antagonists exhibited a high fungistatic activity againstF. udum.

    Notes: Summary The interrelationship between the growth ofCoprinus lagopus andFusarium udum on pigeon pea substrates in soil was studied at 22-2°C and 30±2°C in relation to their competitive saprophytic ability and antagonism.C. lagopus was observed to be a potent and frequent colonizer of pigeon pea substrates in soil along withF. udum. Saprophytic colonization of pigeon pea substrate byF. udum precolonized byC. lagopus was inhibited in all inoculum soil mixtures. Saprophytic colonization of the substrate byF. udum was better at 22°C than at 30°C and that byC. lagopus better at 30°C than at 22°C. The colonization of substrate by each fungus was suppressed by the other fungus depending upon the temperature used. Hyphal parasitism and colony interactions between these fungi and also with a number of other saprophytic fungi were investigated. No antagonistic reaction was observed betweenF. udum andC. lagopus. However, these fungi were observed to be potent antagonists against other microfungi tested. The formation of fruiting bodies ofC. lagopus was also observed in the laboratory on nutrient media but more frequently on pigeon pea substrates.
