Several species of nematodes are damaging to olive, including the citrus nematode (Tylenchulus semipenetrans), root lesion nematode (Pratylenchus vulnus), and root-knot nematodes (Meloidogyne spp. e.g. Unlike pesticides, nematodes continue working for quite some time after the first application -a single host can produce 300,000 to 400,000 new nematodes, which then seek additional victims. Once inside, the nematode kills them, feeds on them and multiplies quickly. For aphids or whiteflies use pymetrozine. It is important in potato production, where it has been used for control of soil-borne nematodes. This combination reduces costs and provides a safer and more environmentally friendly alternative to more hazardous agrochemicals used for turfgrass pest control. Several BCAs, such as insect parasitic nematodes, predatory mites and beetles, parasitic wasps and beneficial fungi and bacteria can be used to reduce pest populations. S. R. Gowen, "Chemical control of nematodes: efficiency and side-effects," in, "Bayer CropScience plans to discontinue Aldicarb by 2014", http://naldc.nal.usda.gov/download/43874/PDF, http://www.fao.org/docrep/V9978E/v9978e08.htm, "Garlic: from nature's ancient food to nematicide", https://en.wikipedia.org/w/index.php?title=Nematicide&oldid=951202376, Creative Commons Attribution-ShareAlike License, This page was last edited on 16 April 2020, at 00:28.

Drenching with water and molasses or sugar can also kill nematodes, but will have a negative impact on soil life. Nonetheless, white grubs have developed a series of behavioral, morphological and physiological barriers to infection during their co-evolution with nematodes, which makes it harder for the worms to penetrate their hosts.

Although the threadlike critters are microscopic, they can cause major damage when they feed on plant tissue or roots. minutes, will “solarize” (cook) the nematodes and kill them. Conclusion.

Fumigant nematicides are most effective in moist but well-drained soil with relatively low levels of organic material. For example, the sugarbeet cyst nematode attacks only a limited number of crops, including cole crops (broccoli, Brussels sprouts, cabbage, cauliflower) and related crops and weeds. Nematodes can be killed by excessive tank agitation through sparging (recirculation of a portion of spray mix) or excessive mechanical stirring that is used to keep the nematodes in suspension. e.g, Gramoxone Insecticides-usedforkillinginsects.e.g.Sevin Fungicides-used for killing fungi.
