Radopholus similis is a species of nematode known commonly as the burrowing nematode. [1] It is a parasite of plants, and it is a pest of many agricultural crops. It is an especially important pest of bananas, and it can be found on coconut, avocado, coffee, sugarcane, other grasses, and ornamentals.
The tobacco cyst nematode, Globodera tabacum, is a serious and important soil borne parasite of the shade [1] [2] and broadleaf [3] tobacco. The most important host plant for this nematode is tobacco (Nicotiana tabacum L), but other hosts include tomato, eggplant and closely related solanaceous weeds.
Water immersion is another option. Infected plants are immersed in a hot water bath for about 30 minutes, which rids them of nematodes but does not harm the plant. This method has been successful for P. coffeae. [9] Crop rotation can help control the nematode load in the soil because different plants are susceptible to different Pratylenchus ...
Nematode assays need to be done before stepping on any managements later. Threshold for plant and first ratoons (per gram of roots) is 300 while threshold for old ratoons (per gram of roots) is over 900. [3] Crop rotation with legume plants on sugarcane fields can reduce the number of plant parasitic nematodes. However, this management has a ...
Meloidogyne incognita (root-knot nematode, RKN), also known as the southern root-nematode or cotton root-knot nematode is a plant-parasitic roundworm in the family Heteroderidae. This nematode is one of the four most common species worldwide and has numerous hosts. It typically incites large, usually irregular galls on roots as a result of ...
Nematodes can effectively regulate bacterial population and community composition—they may eat up to 5,000 bacteria per minute. Also, nematodes can play an important role in the nitrogen cycle by way of nitrogen mineralization. [73] But plant parasitic nematodes cause billions of dollars in annual crop damage worldwide. [74]
Root-knot nematodes (Meloidogyne spp.) are one of the three most economically damaging genera of plant-parasitic nematodes on horticultural and field crops.Root-knot nematodes are distributed worldwide, and are obligate parasites of the roots of thousands of plant species, including monocotyledonous and dicotyledonous, herbaceous and woody plants.
Hirschmanniella oryzae, i.e. rice root nematode (RRN), is among the major pests of rice and is the most common plant-parasitic nematode found on irrigated rice. [1] Recent modifications in cultivation practices have led to a substantial increase in rice production, which has been accompanied by heightened levels of RRN. [2]
