USING METHODS OF SOLARIZATION, BIO-FUMIGATION, BURNING AND KEEP DRYING SOIL CONTROL ROOT- KNOT NEMATODES ON LETTUCES, IN LAM DONG

Efficacy of Bio-Fumigation and Soil Solarization on Soil-Borne Onion Pathogens

Specific microbial attachment to root knot nematodes in suppressive soil.

Understanding the interactions of plant-parasitic nematodes with antagonistic soil microbes could provide opportunities for novel crop protection strategies. Three arable soils were investigated for their suppressiveness against the root knot nematode Meloidogyne hapla. For all three soils, M. hapla developed significantly fewer galls, egg masses, and eggs on tomato plants in unsterilized than ...

Coastal Bermudagrass Rotations for Control of Root-knot Nematodes:.

The use of 1,2-dibromo-3-chloropropane (DBCP) and e thy lene d ib romide (EDB) as soil fumigants to control nematodes has been banned. Other nematicides are more expensive and often less effective than DBCP and EDB and may experience a similar fate. A renewed interest in biological control o f nematodes will surely follow. Among root-knot nematode-resistant crops that may be used in rotation wi...

Effects of Soil Textures on Infectivity of Root-Knot Nematodes on Carrot

This study was conducted to examine infectivity (penetration and gall and egg-mass formations) of the root-knot nematodes, Meloidogyne incognita and M. hapla, on carrots grown in soil conditions of 5 different soil textures consisting of bed-soil (b) and sand (s) mixtures (b-s mixtures) at the ratios of 10:0, 7:3, 5:5, 3:7, and 0:10. For M. incognita, the nematode penetration rates in b-s of 0:...

Influence of water and soil temperature on the concentration and efficacy of phenamiphos for control of root-knot nematodes.

Field plots of Tifton loamy sand were treated with phenamiphos for control of root-knot nematodes in a multiple-crop system of turnips, field corn, and southern peas. Preplant applications of phenamiphos protected roots of turnips and corn from damage by root-knot nematodes. Concentrations of phenamiphos at application in the 0-15-cm soil layer were near 6 mug/g on turnips and near 4 mug/g on c...
