make sure that the soil is not infested before planting and that the transplants are free of nematodes. The type of cover crop used in peach orchards can have a considerable effect on the degree of attack by root knot nematodes and consequently on the growth and yield of the trees. In experimental plots in Georgia, trees on plots where root knot resistant cover crops were planted produced about...

The endoparasitic nematophagous fungus Meria coniospora reduced root-knot nematode galling on tomatoes in greenhouse pot trials. The fungus was introduced to pots by addition of conidia at several inoculum levels directly to the soil or addition of nematodes infected with M. coniospora to the soil; both methods reduced root galling by root-knot nematodes. These studies represent a part of a rec...

Root-knot nematodes cause annual losses of about USD $100 billion worldwide. Development of natural resistance to nematicides by nematodes and the tendency to withdraw chemical pesticides/nematicides from the market led to the search for new methods of control. Biological control of root-knot nematodes with Paecilomyces lilacinus is being investigated thoroughly, but there is a lack of informat...

To determine the presence and level of root-knot nematode (Meloidogyne spp.) infestation in Southern California bell pepper (Capsicum annuum) fields, soil and root samples were collected in April and May 2012 and analyzed for the presence of root-knot nematodes. The earlier samples were virtually free of root-knot nematodes, but the later samples all contained, sometimes very high numbers, of r...

Root-knot nematode is an important pest in agricultural production worldwide. Crop rotation is the only management strategy in some production systems, especially for resource poor farmers in developing countries. A series of experiments was conducted in the laboratory with several leguminous cover crops to investigate their potential for managing a mixture of root-knot nematodes (Meloidogyne a...

root-knot nematodes, meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. the most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. in the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. in the supplementary studie...

Olive knot disease, caused by Pseudomonas savastanoi pv. savastanoi, is one of the most important biotic constraints for olive cultivation. Pseudomonas fluorescens PICF7, a natural colonizer of olive roots and effective biological control agent (BCA) against Verticillium wilt of olive, was examined as potential BCA against olive knot disease. Bioassays using in vitro-propagated olive plants wer...

Pseudomonas savastanoi pv. savastanoi (Gardan et al., 1992) (hereafter Psv, according to Vivian & Mansfield (1993)) is the causal agent of olive knot disease. It is considered one of the most serious diseases affecting olive trees (Olea europaea L.) in most olive growing regions worldwide and mainly in Mediterranean countries, where this crop has been growing for centuries. The disease can lead...

Okra [Abelmoschus esculentus L., Moench] a native of South-Africa and commonly known as ‘Bhindi’ is an annual malvaceous vegetable crop, especially grown in tropical subtropical climates. It also called “perfect villager’s vegetable”. Root-knot nematodes are considered among the top five major plant pathogens first ten most important genera parasitic world. Amongst nematodes, root-knot nematode...
