DiTera is a biological nematicide of microbial origin with potential for managing several plant-parasitic nematodes in different crops. Efficacy of ABG-9008, an earlier formulation related to DiT-era, to control the burrowing nematode of bananas was evalu... see more

In vitro explants of a rootstock and two cultivars of olive were used in a screening trial for resistance to Meloidogyne incognita. All plants were susceptible to the root-knot nematode independently of the inoculum used, egg masses or eggs. The in vitro ... see more

The spatial distribution of nematode populations and damage in roots of Nabusa (Musa AAA-group Matooke), Pisang Awak (Musa ABB) and Sukali Ndizi (Musa AB) three banana cultivars widely grown in Uganda, was investigated at three locations, each with a dist... see more

The use of corn as a rotation crop in integrated programs for controlling plant-parasitic nematodes has been widely recommended. In Brazil, where most of the commercial varieties and hybrids have been rated as resistant to root-knot nematodes for many yea... see more

An experiment to compare nematode management tactics was conducted in South Lebanon on cucumber in commercial greenhouses naturally infested with the root-knot nematodes Meloidogyne incognita and M. javanica. Significant increases in fruit yield and a red... see more

A three-year nematicide study in north Florida, involving four separate cotton field trials, was conducted in loamy sand soils infested with Rotylenchulus reniformis. Cotton lint yield responses and post-harvest soil infestation levels of R. reniformis we... see more

The relationship between a geometric series of fourteen initial population densities (Pi) of Meloidogyne exigua between 0 and 512 eggs and juveniles/cm 3 soil and growth of coffee (Coffea arabica) was investigated in one-liter clay pots. The Seinhorst mod... see more

In this paper evidence is presented for the reproduction of Radopholus similis in foliar tissues of Anubias barteri Schott. Burrowing nematodes colonized petioles and leaves of A. barteri in addition to the rhizomes. The nematode invaded the epidermis and... see more

The population dynamics of Meloidogyne incognita juveniles (J2) in association with the parasite Pasteuria penetrans was studied in a field in Martinique. Data obtained at three-week intervals for one year were analyzed to study the relationship between J... see more

Root-lesion nematodes, Pratylenchus spp., are among the pests with the greatest negative impact on the economy of coffee production in Guatemala. A field experiment was undertaken in southwest Guatemala to assess damage due to a root-lesion nematode and t... see more

Penetration, development and reproduction of a Harmony pathotype of Meloidogyne arenaria was studied on two resistant grape rootstocks, 10-23B and RS-3. Associated resistance mechanisms were examined microscopically. Cabernet Sauvignon was used as a susce... see more
