Insecticide For Nematodes

As you know, controlling nematodes that plague your lawn and garden is important. But there are a few questions you may have regarding insecticide for nematodes. Let’s go over some of the things you need to know about applying insecticides to control your nematodes, so your lawn and garden can be healthier than ever.

Insecticide For Nematodes

Nematicides (less commonly known as nematocides) are chemical agents used to control parasitic worms such as roundworms and threadworms. Used in various forms for centuries, they are some of the most widely used pesticides worldwide. During the last 50 years, several new nematicides have been introduced or developed, and this class of pesticide is now composed of several agents spanning numerous chemical classifications – from inorganic small molecules to polymers to naturally derived compounds. Toxicological effects of these materials vary due to their inherent diversity in structure and chemical activity, as well as their differing methods of application.

Nematicides, such as fosthiazate, have been developed for the control of nematode pests of crops. Fosthiazate is a soil-applied organophosphate, contact-acting nematicide that controls potato cyst nematodes. Certain chemicals in this group are classified as soil sterilants/fumigants, e.g. Dazomet. It is important to remember that a time interval must be observed between the last application of the pesticide and the harvesting of edible crops, as well as the access of animals and poultry to treated areas. With some pesticides this interval is longer than others. This is another reason for very careful reading of the manufacturer’s instructions.

Applying soil nematicides is justified when severe attacks are observed (high nematode densities in the previous crop) and in cases of replant sickness symptoms following repeated rose crops in the same field or greenhouse. In different countries, different ranges of fumigants (e.g. methyl bromide and dichloropropene), precursors of fumigants (e.g. dazomet) and nonvolatile nematicides (in granular form such as aldicarb) are still authorized for use but the list is becoming more and more restricted because of the negative environmental impact of the chemicals. Methylbromide, for example, which has a remarkably wide-spectrum activity (including weeds, soil fungi, nematodes and insects), will be banned in all countries of the European Union in 2005.

Nematicides protect young plantlets during the first stages of their development and allow their satisfactory installation and subsequent productivity. None the less, none of the nematicides can eradicate nematodes from the soil because individuals can usually survive in deeper levels where they can escape chemical diffusion; reinfestation of the plants will inevitably occur after a few months or years. It is absolutely necessary that preplanting chemical treatments, which act only against nematode stages surviving in the bare soil, are combined with the use of nematode-free nursery plants.

Insecticide For Nematodes

Nematodes are tiny worms that live in soil. They are microscopic, but they can cause big problems in your garden. Nematodes can live in the soil for many years and will attack plants that have roots that are only a few centimeters long. Nematodes feed on plant roots and reduce the plant’s ability to take up water, which weakens it and makes it easier for other organisms to attack the plant.

There are a number of insecticides that target nematodes. These include:

– Imidacloprid (Marathon)

– Thiamethoxam (Pardner)

– Spinosad (Conserve)
