What are the four practical methods of controlling nematodes?

The most reliable practices are preventive, including sanitation and choice of plant varieties. You can reduce existing infestations through fallowing, crop rotation, and soil solarization. However, these methods reduce nematodes primarily in the top foot or so of the soil, so they are effective only for about a year.

What are the types of management of plant-parasitic nematodes?

The options available for plant-parasitic nematode management include sanitation, resistant and tolerant varieties, crop rotation, cover crops, conservation tillage and nematicides. In most cases, a combination of these practices will be needed to keep nematode numbers below the economic threshold.

What are the different methods for the identification of the nematodes?

Morphological and Image-Based Analyses Classic identification of nematodes is based on morphological and anatomical differences using microscopic image analysis. Morphological identification is among the cheaper identification methods and helps relate morphology with possible function [5].

What are the steps in managing nematodes?

These include: 1) using specific management practices; 2) using resistant plant species or varieties; 3) rotating your crops; 4) using organic matter and green manures; 5) growing nematode-suppressive crops; 6) subjecting growing areas to either flooding or fallow; 7) solarizing soil; 8) employing methods of biocontrol …

Which physical method is useful for nematode management?

Heat: Heat treatment is probably the most successful physical control measure developed so far. It is widely used for the killing of nematodes within plant tissues before planting and has proved useful on nematode infested bulbs and tubers, and roots of plants such as chrysanthemums, strawberries, bananas and citrus.

How nematodes can be controlled chemically?

Chemical treatment with fumigants or nematicides may be the only technique available, and from the plant quarantine standpoint it is important that their use is retained. The use of chemicals in protected cropping may still be preferable to other techniques such as steam treatment for economic and practical reasons.

How do you control bad nematodes?

To kill nematodes in soil, heat small quantities of moist soil to 140°F in the oven or by solarization. Heating soil in the oven over a time period needed to bake a medium-sized potato placed in the center of the soil is sufficient to kill nematodes; however, this is only practical for small quantities of soil.

How are nematodes controlled biologically?

In this respect, filamentous fungi can be an interesting biocontrol alternative. The genus Trichoderma, mycorrhizal and endophytic fungi are the main groups of filamentous fungi studied and used as biological control agents (BCAs) against nematodes as resistance inducers.

What are the four classifications of nematodes?

Commonly known as roundworms, nematodes are a group of worms that make up the phylum Nematoda. With well over 15,000 species identified today, they can be found in different habitats ranging from terrestrial to marine environments….Definition – What are Nematodes?

  • Ascarids.
  • Filarias.
  • Whipworms.
  • Adenophorea.
  • Enoplea.

How many types of nematodes do we have?

There are thousands of nematodes. Not only are there more than 15,000 known species of roundworms, but there are many thousands of individual nematodes in even a single handful of garden soil.
