A nematicide is a type of chemical pesticide used to kill plant-parasitic nematodes. Nematicides have tended to be broad-spectrum toxicants possessing high volatility or other properties promoting migration through the soil. Aldicarb (Temik), a carbamate insecticide marketed by Bayer CropScience, is an example of a commonly used commercial ...
Foliar nematodes occur throughout the United States in greenhouse and nursery settings. Foliar nematodes travel in films of water, swimming up the stems of plants and entering leaf tissue through stomata. The nematodes are transmitted plant to plant by splashing, overhead irrigation, rainfall, and other forms of dripping water. They can also be ...
Heterorhabditis bacteriophora is a species of entomopathogenic nematode known commonly as beneficial nematodes. They are microscopic and are used in gardening as a form of biological pest control . They are used to control ants , fleas , moths , beetles , flies , weevils , and other pests.
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.
Sanitation of equipment is also important to controlling the nematode. Pots potting soil, and tools should be cleaned by baking or steaming at 180-200 degrees Fahrenheit for 30 minutes. [18] Care must be taken so that the temperatures needed to eliminate the infesting nematodes does not irrevocably harm the plant material. [3]
The habit of feeding on nematodes has arisen many times among fungi, as is demonstrated by the fact that nematophagous species are found in all major fungal groups. [3] Nematophagous fungi can be useful in controlling those nematodes that eat crops. Purpureocillium, for example, can be used as a bio-nematicide.
Foliar nematodes are an important plant pathogen to agricultural crops and ornamental plants in the United States, Canada, and Europe. [1] Aphelenchoides fragariae nematodes are found in over 200 plant host species, [2] including crop species strawberry and alfalfa, and ornamental species Begonia, Chrysanthemum, Dahlia, Ficus, Hibiscus, Hosta, Viola, ferns, and Zinnia.
