Control of the root-Knot nematode meloidogyne incognita on table grape by using certain sugarcane residues in newly reclaimed soil

Efficacy of two sugarcane residues, bioearth as compost and filter cake or mud as non-compost at the rates of 100 g and l kg/vine compared to chemical nematicide, oxamyl 24% L in controlling Meloidogyne incognita on table grape cv. Flame Seedless was investigated in newly reclaimed soil under field conditions. The two residues caused considerable reduction in J2 populations in soil and roots, especially at midseason and at the highest rate of both materials. At harvest, however, the population [J2] tended to build up again. Vine yield surpassed those of the check by 41.4% for bioearth and 67.1% for filter cake at the highest rate. Oxamyl achieved 28.6% yield increase over that of check. Lower C/N ratio appeared to affect antagonistic microorganisms resulting in lowering nematode population

Effect of glycyrrhiza [glycyrrhiza glabra] and henna [lawsonia inermis] plant wastes on controlling the root-Knot nematode, meloidogyne incognita on eggplant [solanum melongena]

Dry powdered root of glycyrrhiza and henna leaf powder were applied at the rates of 0.1, 1 and 10 g/pot for controlling Meloidogyne incognita on eggplant cv. Pusa Purple Long under greenhouse conditions. The higher rates [1 and 10 g] of glycyrrhiza did not decrease the number of galls and eggmasses, and plant growth parameters increased over those of the check. In contrast, increasing rates of henna powder reduced the numbers of galls and eggmasses in an increasing manner. Meanwhile, plant growth parameters insignificantly decreased in comparison with the check. Lower C/N ratio appeared to affect microbial activity resulting in lowering nematode population
