...for vegetables including eggplant. Chemical control of nematodes is hazardous to health and causes environmental pollution by contaminating underground water. The bio-protectant potential of mycorrhizal fungus (Glomus mosseae) and neemex® (Azadirachtin) against invasion and development of Meloidogyne incognita was tested in eggplant roots in greenhouse pot trials. Neemex (5 g, 10 g and 15 g) and G. mosse...

Sudden outbreak of mealy bug and armoured scale causing severe damage to economic crops in Bangladesh
...nt vegetable crops viz., eggplant, lady's finger, papaya, basil etc. by citrus mealybug, Planococcus citri (Risso) (Homoptera: Pseudococcidae) has been noticed in Bangladesh. It is mainly a pest of citrus and coffee crops but now it has become polyphagous in nature. Based on laboratory studies on immature and mature fruits of lady's finger; the total period of all four nymphal stages lasted for 32.6 ± 4.17 days at an average room temperature of 28 &plus...

The recommended doses of Nitenpyram, Clothianidin, Momentum (combination of Nitenpyram+Chlorfenapyr) and Buprofezin were applied when population of insect pests reached at economic threshold level (ETL). Pre-treatment data were taken before 24 hours and post-treatment data were record...

Results revealed that all tested doses of milbemectin suppressed galls (ranged from 50.59 to 75.50%, of both experiment) and egg masses (ranged from 66.67 to 87.01%, of both experiment) significantly, while fenamiphos recorded moderate reductions. Also, the measured plant indices wer...

The STP source was more suppressive to nematode development than ITB irrigation source in the two inoculation times of treatments either in sandy soil or sandy loam soil. Also, the produced eggs were highly influenced by the STP source achieving half of the produced eggs in the ITB after 45 days of inoculation time...

...kistan, the low yield of eggplant is ascribed to legions of biotic constraints. Among biotic restraints, root-knot nematodes, Meloidogyne spp. are economically very important and cause losses to the tune of $ 125 billion per year throughout the world. The present studies were aimed to evaluate 21 eggplant genotypes against the most destructive nematode, Meloidogyne incognita, under greenhouse conditions. Of all the genotypes...

The obtained results proved that, the tested isolates adversely affected reproduction of root-knot nematode, M. incognita, either when bacterium was added before, after or at the same time with Ne inoculation. On the basis of the average overall percentages nematode reduction, bacterial isolates added before and after nematode inoculation were equal in decreasing M. incognita numbers, as they...

It was found that there is a positive correlation between eggplant density and population density of root-knot nematode, M. incognita in roots i.e., when number of plants in the same pot increased (1-4 plants/pot), a higher number of nemato...

For this, 10 concentrations of methanolic extract of plant (0.5% to 5%) were employed against the pathogens. Data analysis depicted that development of all the pathogens was greatly inhibited by all the concentrations while 5% concentration found to be the utmost operative in subduing the growth of all the pathogens.
