How many beneficial nematodes do i need
To complete the lifecycle, they also lay their offspring in the dead grub or other pest. There are different kinds of nematodes for targeting different turf insects, but we carry the nematodes that go after grubs! Nematodes are super easy to use , require very little work and no sprays! You get a whopping 10 million nematodes in an individual package. That will cover an area between square feet based on a heavy or light application rate. They are shipped in a powdery solution that mixes well in water.
Be sure to keep your nematodes in the fridge but not frozen and apply as soon as possible for best results. Adult pest populations should gradually decrease as the nematodes continue to kill infected life stages. Nematodes are recommended for use whenever larvae or grubs are present. Generally, this is during the spring and fall months. Because larvae feed on plant roots, beneath the soil surface, severe damage can be done before realizing there is a problem.
Look for signs of an adult insect, such as leaf-notching. If adult insects are present, their eggs will be hatching soon. Keep in mind, one application may not eradicate a population of insects that has become established over a period of years. In general, harsh winter weather in most parts of the country almost guarantees a significant decline in the population of the nematodes. In most cases, nematodes just like insects will become dormant during cold weather.
Any survivors would be few in number to provide adequate insect control. If your insect pest returns the following year, another application may be necessary. Nematodes, due to their microscopic nature have limited range of movement. How are Beneficial Nematodes Shipped? Remove nematode tray s and sleeves from insulated shipping container or packaging and place in refrigerator until ready to use.
The Beneficial Nematodes are shipped in an easily dissolved formulation that you mix with water. Cranshaw and R. Zimmerman with Colorado State University. Call us at with questions. We look forward to speaking with you! For the successful control most of the soil dwelling insect pests, the optimal rate of 1 billion infective juvenile nematodes in to gallons of water per acre is generally recommended.

Apply nematodes in the early evening or late afternoon when soil temps are lower and UV incidence is lower as well cloudy or rainy days are good too. In most cases, there is no need for special application equipment. Most nematodes species are compatible with pressurized, mist, electrostatic, fan and aerial sprayers!
Hose-end sprayers, pump sprayers, and watering cans are effective applicators as well. Nematodes are even applied through irrigation systems on some crops.
Check the label of the nematode species to use the best application method. Repeat applications if the insect is in the soil for a longer period of time. There is no need for masks or specialized safety equipment. Insect parasitic nematodes are safe for plants and animals worms, birds, pets, children. Because they leave no residues, application can be made anytime before a harvest and there is no re-entry time after application. How to use beneficial nematodes: For the home gardener, localized spraying is probably the quickest and easiest way to get the nematodes into the soil.
Producers ship beneficial nematodes in the form of dry granules, powder type clay, and sponges. All of these dissolve in water and release the millions of nematodes. Each nematode ready to start searching for an insect in your lawn or garden.
Nematodes should be sprayed on infested areas at the time when pests is in the soil. Timing is important, or else you will have to repeat the application. Northern gardeners should apply the nematodes in the spring, summer and fall, when the soil contains insect larvae.
Most of the beneficial nematodes are adaptive to cold weather. In fact , the very best time to control white grubs is in the spring and fall. If your in a warmer climate, beneficial nematodes are effective all year. Some pesticides work well with nematodes when their mutual exposure is limited while other pesticides may kill nematodes.
Check labels or specific fact sheets to find out. Some chemicals to avoid are bendiocarb, chlorpyrifos, ethoprop, and isazophos. Fungicides to avoid are anilazine, dimethyl benzyl, ammonium chloride, fenarimol, and mercurous chloride.
The herbicides, 2,4-D and trichlopyr and nematicide, fenamiphos, should be avoided as well. During hot weather release nematodes in the evening or afternoon when temperature is cooler.
Release once or twice a year or until infestation subsides. Nematodes are shipped in the infectious larvae stage of their life cycle and can be stored in the refrigerator for up to 4 weeks.
Always release very early in the morning or late in the late afternoon. Why are these organisms beneficial? Parasitic nematodes are beneficial for eliminating pest insects. First, they have such a wide host range that they can be used successfully on numerous insect pests.
The nematodes' nonspecific development, which does not rely on specific host nutrients, allows them to infect a large number of insect species. Nematodes enter pest bugs while they are still alive, then they multiply inside the bugs which eventually die and finally burst out of the dead bodies. The number of nematodes inside a single bug depending on the species ranges from 5, to 10, Although you can barely see one young nematode with your naked eye, large groups of these tiny wigglers pouring out of the dead insects are easy to see.
Then the nematodes wriggle off to find other insects to "invade," starting the whole cycle all over again. Second, nematodes kill their insect hosts within 48 hours. As mentioned earlier, this is due to enzymes produced by the Xenorhabdus bacteria.
Also, the infective juveniles can live for some time without nourishment as they search for a host. Finally, there is no evidence that parasitic nematodes or their symbiotic bacteria can develop in vertebrates. This makes nematode use for insect pest control safe and environmentally friendly. The United States Environmental Protection Agency EPA has ruled that nematodes are exempt from registration because they occur naturally and require no genetic modification by man.
Beneficial nematodes can be an excellent tool in the lawn and garden to control certain pest insects. They can be used with organic gardening and are safe for kids and pets.
