Cover crops with biofumigation properties for the suppression of plant-parasitic nematodes : a review

Kruger, D. H. M. Fourie, J. C. Malan, Antoinette P. (South African Society for Enology and Viticulture, 2013-08)

Plant-parasitic nematodes are a problem in vineyards worldwide, with some species acting as vectors of grapevine soil-transmitted viruses. Global pressure on the use of soil-applied chemical nematicides has led to a ...
Options for soil health measurement in vineyards and deciduous fruit orchards, with special reference to nematodes

Kapp, C. Storey, S. G. Malan, Antoinette P. (South African Society for Enology and Viticulture, 2013-07)

Soil is a non-renewable resource and supports all land-based forms of life. The sustainable production of crops is becoming progressively more critical as human populations increase and viable agricultural land decreases. ...

Bacterial strain SF87T, and additional strains SF80, SF362 and 106-C, isolated from the nematode Steinernema khoisanae, are non-bioluminescent Gram-reaction-negative bacteria that share many of the carbohydrate fermentation ...
Effect of humidity and a superabsorbent polymer formulation on the efficacy of Heterorhabditis zealandica (Rhabditida: Heterorhabditidae) to control codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae)

De Waal, Jeanne Y. Malan, Antoinette P. Addison, Matthew F. (Taylor & Francis, 2013-12)

Adequate moisture levels are required for nematode survival and subsequent efficacy as entomopathogens. Formulation of nematodes aimed at aboveground applications may assist in maintaining such moisture levels. In this ...
Adjuvants to improve aerial control of the citrus mealybug Planococcus citri (Hemiptera: Pseudococcidae) using entomopathogenic nematodes

Van Niekerk, S. Malan, A. P. (Cambridge University Press - CUP, 2013-11)

The citrus mealybug, Planococcus citri, is a highly destructive pest of citrus, occurring only in the aerial parts of plants. Humidity will be one of the key factors to consider when using entomopathogenic nematodes (EPN) ...
Potential of entomopathogenic nematodes for the control of the banded fruit weevil, Phlyctinus callosus (Schonherr) (Coleoptera: Curculionidae)

Ferreira, T. Malan, A. P. (Cambridge University Press - CUP, 2013-02)

Entomopathogenic nematodes (EPN) were evaluated for their potential use as biological control agents against Phlyctinus callosus, the banded fruit weevil (BFW). The susceptibility of larvae and adults to EPN was evaluated ...
