Management of the Root-Knot Nematode, Meloidogyne incognita on Tomato Plants by Pre-Planting Soil Biofumigation with Harvesting Residues of Some Winter Crops and Waste Residues of Oyster Mushroom Cultivation under Field Conditions
Journal Title: Egyptian Journal of Agronematology - Year 2014, Vol 13, Issue 1
Abstract
A field trial was carried out to study the effect of pre planting soil biofumigation with air-dried powders of harvesting residues (leaves) of artichoke, cauliflower, sugar beet, table beet, taro and turnip) and waste residues of oyster mushroom cultivation (applied at 300g/m2), comparing to the chemical nematicide fosthiazate 10%G (Nemathorin®) applied at 12.5 kg/feddan for the management of the root-knot nematode, Meloidogyne incognita on tomato plants cv. Alisa. All treatments greatly managed M. incognita infection on tomato plants. Numbers of root galls, nematode egg masses, final population (Pf) and reproduction factor (Rf) in all treatments were significantly reduced as compared to control plants (infected with nematode only). Treatment with fosthiazate 10% provided the maximum reduction (91.47%) of nematode infection on tomato plants, followed by treatments with leaf powders of taro (90.49%), turnip (84.95%), artichoke (82.72%), table beet (81.37%), cauliflower (79.23%), and sugar beet (76.98%). Treatment with waste residues of oyster mushroom cultivation recorded the minimum reduction (67.93%). On the other hand, all treatments significantly increased growth criteria of tomato plants comparing to the control ones. The increase of total fresh weight was ranged between 69.4-223.7% and fruit yield per plant was considerably increased by 134.3-709.9%. It seems that soil biofumigation with plant residues studied herein may consider a promising and economic strategy in managing root-knot nematode infection on tomato plants, particularly in programs of non chemical control practiced in organic farming.
