Three different plant extracts (Khaya ivorensis, Azadirachta indica and Daniella oleifera) and two Trichoderma species (T. harzianum and T. atroviride), singly and in combination, were assessed on nematode population changes and also in the control of plant parasitic nematodes on tomato under field condition during 2018 and 2019 planting seasons. During each trial, plant parasitic nematodes encountered in the field were Meloidogyne, Pratylenchus, Xiphinema and Helicotylenchus species. The experiment was a randomized complete block design with 4 x 3 factorial scheme and five replications. Factor A being plant extracts (Khaya ivorensis, Azadirachta indica, Daniella oleifera) and control, and factor B being bio-control agents (Trichoderma harzianum, T. atroviride) and control, resulting in 12 treatments. Significant reductions were observed on the population of the plant parasitic nematodes at all treatment levels with neem plant extract, in combination with either T. harzianum or T. atroviride resulted in the greatest significant decrease. Applications of different plant extracts and Trichoderma species, singly and in combination, enhanced the growth and yield of tomato infected with parasitic nematodes.

Plant Parasitic

Rice, pulses and oilseed crops are major exporting crops in Myanmar. Many plant-parasitic nematodes, such asMeloidogyne incognita,M. javanica,M. graminicola,Ditylenchus angustus,Hirschmanniella oryzae,Heterodera cajaniandPratylenchusspp., have been detected in these crops in different cropping patterns and are considered one of the reasons for their low yields. Previous surveys have shown potential impact to yield losses in the crops. This Forum article provides collective information on species of the major plant-parasitic nematodes, possible damage and available control measures to such economically important crops in Myanmar.

A study was undertaken to isolate and identify different genera of plant parasitic nematodes from soil and plant samples during July to October 2007 in the Laboratory of Plant Pathology at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh. Altogether 10 (Ten) nematodes belonging to 10 genera were isolated and identified from various soil and plant samples. For identification of plant parasitic nematodes, stylet and other anatomical structures such as Dorsal esophageal Gland Orifice (DGO), Esophageal lumen, Median bulb, Basal bulb, Intestine, Reproductive structures (vagina and its position, specula ) Tail types etc. were used as main criteria. Among 10 (ten) different identified genera of nematodes (Criconemoids sp., Hemicriconemoides sp., Tylenchus sp., Ditylenchus sp., Tylenchorhynchus sp., Hoplolaimus sp., Helicotylenchus sp., Pratylenchus sp., Meloidogyne sp., Radinaphelenchus sp.) maximum nematodes were under the family of Tylenchidae. The abundance numbers of plant parasitic nematodes were found as the Ditylenchus sp.(Ufra nematode) and Meloidogyne sp.(Root knot nematode) which were the serious plant pathogens causing ufra in rice and root knot in different crops respectively, so far recorded in Bangladesh. Key words: Isolation; Identification; Plant parasitic nematodes. DOI: 10.3329/bjsir.v45i3.6536Bangladesh J. Sci. Ind. Res. 45(3), 267-270, 2010
