What is the use of nematicides?
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.
How do you control nematodes in turfgrass?
Most cultural practices for nematode feeding pressure aim at increasing the root system. Watering: Deep, infrequent watering is recommended during the entire year. This encourages the plant to produce deep, robust rooting systems. Deeper roots reduce drought stress and the impact of nematode damage in the summer.
How do I treat nematodes in my lawn?
Mix up a solution of fresh, infective stage nematodes in cool, distilled water, pour the solution into a sprayer, and apply to the infected area. Apply nematodes in the evening, especially in hot areas. Nematodes are killed by light and heat. Irrigate after application.
What are nematicides give two examples?
The liquid formulations of some of the non-fumigant nematicides are emulsifiable concentrates….Chemical control of nematodes.
| Chemical name | Trade name | Formulation |
|---|---|---|
| Ethoprophos | Mocap | Granular or emulsifiable liquid |
| Fenamiphos | Nemacur | Granular or emulsifiable liquid |
| Fensulfothion | Dasanit | Granular |
| Terbufos | Counter | Granular |
What do you mean by nematicides?
Definition of nematicide : a substance or preparation used to destroy nematodes.
When should I put nematodes on my lawn?
Nematodes are most effective when the soil temperature reaches about 15C. This is weather dependent year to year but it is usually around mid May. When you see them available in your local garden centers, it is the correct time to apply them, not before.
Which are the examples of nematicides?
Should we continue to use chemical nematicides?
The elimination of nematodes from some crops is essential for certain export requirements, particularly of high-value horticultural products. 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.
Can nematodes damage lawn?
Nematodes injure lawns by feeding on plant root cells with their needle-like mouthparts (stylets). As a result, the root system becomes damaged to where the lawn cannot properly absorb water and nutrients. Then the lawn becomes thin and weak, making it much more susceptible to other stresses, such as drought.
Can nematodes damage grass?
The appearance of chlorotic patches is often the first indication that plant parasitic nematode feeding is causing significant damage to turfgrass. A common feature of nematode damage is that symptoms will first appear when grasses are experiencing some degree of stress.
How long do nematodes take to work?
3-7 days
How Long Does It Take To See Results? Usually 3-7 days, with maximum effect occurring over 2-4 weeks. Nematodes disintegrate the pests from the inside out, so you will not see dead insect bodies as you would with a chemical knockdown.
Do nematicides work on turf nematodes?
The new nematicides can work just as well, but no single product can control all species of turf nematodes. Divanem, Indemnify and Nimitz Pro G are three new products available for nematode control in turf.
What do new nematicides mean for golf course superintendents?
These new nematicides, along with the ones already in the arsenal, provide golf course superintendents with multiple tactics for managing nematodes. However, each new nematicide works better on some nematodes than on others.
How can I reduce nematode stress on my turfgrass?
The use of cultural control methods to reduce stress on turfgrasses is very important, particularly during the summer months. Methods are unlikely to reduce nematode population numbers, however they may help turfgrasses tolerate feeding damage. Most cultural practices for nematode feeding pressure aim at increasing the root system.
How should I select nematicides for my nematodes?
Nematicides should be chosen for use based upon previous sampling for species as each one doesn’t control all nematodes that may be present. Multiple nematicides may be necessary in a rotation to avoid selecting for certain species and for resistance management.
