Effect of initial population density of Pratylenchus brachyurus on maize

The effect of pre-plant population density (Pi) of Pratylenchus brachyurus on the growth of maize and reproduction of the nematode was studied in the screenhouse. All growth parameters were reduced at all populations tested when compared with the control. Reduction was significant even at Pi of 500...

Description
Summary:The effect of pre-plant population density (Pi) of Pratylenchus brachyurus on the growth of maize and reproduction of the nematode was studied in the screenhouse. All growth parameters were reduced at all populations tested when compared with the control. Reduction was significant even at Pi of 500 nematodes per 5-litre pot. Both penetration and reproduction of the nematode increased as Pi increased but at a declining rate. These reached a maximum at a density of 2000 nematodes per pot.
