Root-knot nematodes, Meloidogyne spp., are the major nematode pests of economic crops worldwide. Use of conventional nematicides has been one of the most effective methods to reduce their populations. However, the ban on many effective nematicides in recent past has necessitated the search for alternative sources of effective and ecofriendly chemicals for nematode control. The nematicidal potential of fifteen Leguminosae seeds (wild and cultivated) was assessed, in vitro, against juveniles of Meloidogyne incognita (Kofoid & White) Chitwood. Each standard aqueous seed extract, 25g/100ml (w/v), was evaluated at dilutions, 1:10, 1:20, and 1:40 at 27+1�C for 24 hours. The majority of seed extracts caused high mortality rates, especially in 1:10 concentration. Trigonella foenum graceum, Sesbania sesban, Albizzia lebbak, Cassia fistula and Pongamia glabra were the most efficacious (above 90% mortality). S. sesban and P. glabra were significantly effective even in the lowest concentration (1:40).

Parasites (protozoa, helminthes, arthropods) represent a main threat for poultry worldwide. Among helminthes, nematodes constitute the most important group of parasites of poultry. The nematode Ascaridia galli, the cause of ascaridiosis in poultry, is one of the most important and prevalent parasites, resulting in serious economic losses, associated with the treatment cost, the decreased feed efficiency, and the poor egg and meat production. During the past few decades the indiscriminate use of anthelmintic drugs has generated several cases of resistance in helminthes in poultry, situation which is coupled with the severity of residues in poultry products. For this reason, nowadays attention has been drawn to the use of botanicals in poultry diet, due to their anthelmintic properties. Furthermore, the dietary use eco-friend ly of these plant derived substances compared to conventional synthetic anthelmintic drugs is considered as a natural and ecofriendly approach by the consumers. The focus of the present review is to recapitulate the studies, both in vivo and in vitro, that have demonstrated the anthelmintic efficacy of various dietary botanicals in controlling poultry ascaridiosis.

AbstractLeaves of Leucaena leucocephala, Sesbania sesban and Calliandra callothyrsus were harvested in Rwanda from young shoots at 8 weeks after the first cutting. They were dried, ground and incubated at the same time in polyester bags in three non-lactating Holstein-Friesian cows each fitted with a ruminal cannula. The bags were removed at 0, 2, 4, 8, 24, 48, 72 and 144 h after the start of incubations. The different parameters characterizing extent and rate of ruminal degradation of organic matter (OM), neutral-detergent fibre (NDF), and crude protein (CP) were calculated. In vitro digestibility of residual protein after 24 h and 48 h incubation was also determined. Sesbania sesban had lowest cell wall contents and gave highest ruminal degradability for OM, NDF and CP. Leucaena leucocephala was degraded to a lesser extent, but its undegraded protein had a somewhat higher in vitro digestibility. In contrast, protein of Calliandra callothyrsus was poorly degraded and digested. The proportion and composition of cell wall could not explain these differences in digestion characteristics and other measurements, such as tannins, were incriminated. Increased ruminal incubation time augmented the extent of ruminal degradation and reduced in vitro digestibility of undegraded protein but did not affect the undigestible protein fraction.

AbstractThe in vitro nematicidal effect of Chenopodium ambrosioides and Castela tortuosa n-hexane extracts (E-Cham and E-Cato, respectively) on Haemonchus contortus infective larvae (L3) and the anthelmintic effect of these extracts against the pre-adult stage of the parasite in gerbils were evaluated using both individual and combined extracts. The in vitro confrontation between larvae and extracts was performed in 24-well micro-titration plates. The results were considered 24 and 72 h post confrontation. The in vivo nematicidal effect was examined using gerbils as a study model. The extracts from the two assessed plants were obtained through maceration using n-hexane as an organic agent. Gerbils artificially infected with H. contortus L3 were treated intraperitoneally with the corresponding extract either individually or in combination. The results showed that the highest individual lethal in vitro effect (96.3%) was obtained with the E-Cham extract at 72 h post confrontation at 40 mg/ml, followed by E-Cato (78.9%) at 20 mg/ml after 72 h. The highest combined effect (98.7%) was obtained after 72 h at 40 mg/ml. The in vivo assay showed that the individual administration of the E-Cato and E-Cham extracts reduced the parasitic burden in gerbils by 27.1% and 45.8%, respectively. Furthermore, the anthelmintic efficacy increased to 57.3% when both extracts were administered in combination. The results of the present study show an important combined nematicidal effect of the two plant extracts assessed against L3 in gerbils.

Sarocladium oryzae (Sawada) W. Gams & D. Hawksworth, the causal agent of sheath rot of rice was isolated from sheath rot infected rice sheaths and grains. Among ten tested fungicides Tall 25 EC completely inhibited radial growth of the fungus even at the lowest concentration 100 ppm. Similarly ethanol leaf extract of ten plants, namely Allium sativum, Artocarpus heterophyllus, Asparagus racemosus, Azadirachta indica, Citrus medica, Datura metel, Mangifera indica, Nerium indicum, Senna alata and Tagetes erecta at 5, 10 and 20% concentrations were screened for their fungicidal activity against the test fungus. All the plant extracts completely inhibited the radial growth of the test fungus at 20% concentration except Asparagus racemosus and C. medica. Ethanol extract of Tagetes erecta and Mangifera indica also completely inhibited the radial growth of the test fungus at 10% concentration.Bangladesh J. Sci. Res. 29(1): 47-54, June-2016
