“…As the biomass of microorganisms and plants was not affected by benomyl, the observed response of the nematode fauna is not due to a reduction in food source, and therefore implies a direct toxicity. In contrast, other investigations on benomyl report either no in uence on soil nematode density (Martikainen et al, 1998) or only in combination with nematicides (Abu Elamayem et al, 1978). However, sublethal side effects on non-target organisms are known for earthworms (Kula, 1995) and related compounds are used as drenches to control nematode parasites of farm animals.…”

Nutrient availability is a major constraint on plant production and carbon storage in arctic ecosystems but knowledge on the decomposer food web interactions and their effect on nutrient cycling is scarce. We manipulated the soil food web at two contrasting subarctic sites, a low altitude heath and a high altitude fell-eld. The in ux of nutrients and energy in the soil was increased by addition of fertiliser nitrogen, phosphorus and potassium and of labile carbon (sugar). In addition, two bactericides (penicillin and streptomycin) and a fungicide (benomyl) were applied to manipulate the bacterial and fungal component of the soil. Experiments were carried out in a factorial design with repeated additions over four growing seasons. The present study investigated the nematode fauna and the effects of the manipulations on the abundance of nematode species. Fertilisation resulted in an increase of general opportunists, especially Aphelenchoides. Application of carbon or bactericides had only minor impact on the nematode community. In contrast, the fungicide was very toxic to non-target organisms and greatly reduced the abundance of most nematode species, although Acrobeloides buetschlii showed tolerance and greatly increased in number. At both sites, Eudorylaimus was most affected by the treatments. Generally the manipulations performed resulted in a signi cant increase in stress tolerant or competitive dominant nematode species.

“…on cotton plants. Abou-El-Amayem et al, (1978) showed that numbers of galls per tomato root system and larvae of M.incognita were increased in soil infested with the nematode in combination with R.solani as compared to those in soil infested with nematode alone. Abou-El-Seoud et al, (1987) found that there was synergistic effect of the combination of nematode M.incognita with Cephalosporium maydis on corn.…”

The interaction of Rhizoctonia solani and Meloidogyne incognita Race 3 and Race 4, was tested on four cultivars of American cotton namely RNR-120, RNR-315, DP-50 and Auburn-634.The obtained data revealed that the artificial infection to the susceptible cultivar DP-50 with the fungus in combination with either nematode races increased the root galling from 25-30% in case of nematode alone to 30-40% respectively. Combined infection also increased the pre-emergence damping-off from 60% in case of fungal infection alone to 80%. At the same time the root necrosis of the same cultivar was increased by 25-30% in the combined infection. The second susceptible cultivar to nematode (RNR-315) gave almost similar results in which the pre emergence damping-off was increased from 40% in fungal infection alone to 80% in the combined infection with either races 3 or 4 of the nematode. However, galling and root necrosis were not affected by combined infection.Both cotton cultivars RNR-120 and Auburn-634 were resistant to nematode infection. On the other hand, the pre-emergence damping-off of the cultivar RNR-120 was increased from 80% to 100%, when the race 3 was combined with the fungus. Galling and root necrosis were increased from 10% to 30% under the combination between the fungus and either nematode races 3 and 4. Also, the results showed that cv Auburn-634 was resistant to both nematode races but susceptible to the fungus. Such data revealed that the synergistic effect is limited to susceptible cotton cultivars to nematodes, whereas the nematode resistant cultivars did not affected much by the combined infection of the fungus plus nematode.
