Nematodes are the most numerous multicellular animals on earth. A handful of healthy soil will contain thousands of the microscopic worms, many of them parasites of insects, plants or animals. Free-living species are abundant, including nematodes that feed on bacteria, fungi, and other nematodes, yet the vast majority of species encountered are poorly understood biologically. There are nearly 20,000 described species classified in the phylum Nemata.
Nematodes are structurally simple organisms. Adult nematodes are comprised of approximately 1,000 somatic cells, and potentially hundreds of cells associated with the reproductive system . Nematodes have been characterized as a tube within a tube; referring to the alimentary canal which extends from the mouth on the anterior end, to the anus located near the tail. Nematodes possess digestive, nervous, excretory, and reproductive systems, but lack a discrete circulatory or respiratory system. In size they range from 0.3 mm to over 8 meters. Our Nematodes come in the following sizes and we ship them UPS Second Day Air. Orders are collected and shipped once per week.Mix is approximately 1:4, that is, 1 mil/4 gallons of water. Heavier applications are okay. We recommend you apply them at least in Spring and Fall in northern climates. Don't worry about being exacting in the application. They move through the ground on their own once you water them in so a little variance is okay. We also recommend you use Milky Spore with the nematodes for long term protection against the grubs.
Beneficial nematodes are naturally occurring organisms and are not harmful to humans, pets, wildlife, birds, soil, earthworms, water sources or the atmosphere. Nematodes migrate through the soil finding insect larvae by detecting either a slight increase in temperature or release of methane gas. The infective juvenile nematodes enter the larvae and release a symbiotic bacteria that within days, kills the host. The nematodes feed on the bacteria and the decomposed host tissue where they reproduce until numbers drive them out to find a new host. These Nematodes are effective against over 250 species of pest insects including FLEA LARVAE. In field crops they infect and kill caterpillars, cutworms, grubs, root worms, wire worms, sod web worms and other pests. For greenhouses they are particularly effective against fungus gnats, and aid in the control of pupating thrips in the soil. Orchard pest control is enhanced against codling moth and Lepidopteran pests, including those that bore into tree bark or are in the soil during various stages of their life cycle. For turf and lawns, these nematode packs are particularly effective against cranefly larva, June bug larva and other turf damaging grubs.
For boring insects, some growers spray in the evenings and report successful results against some insects on their tree and shrubs, plant foliage or bark by using Sunspray Ultra-Fine oil to protect the nematodes from desiccation. “Field Guardian" can be stored in a refrigerator at 40o-50oF for 2 weeks. You should mix the package into one gallon of water to create a concentrate. "Field Guardian" can withstand pressures up to 300 PSI. You can apply them using your injector system, or dilute them with more water and use a tank sprayer, boom sprayer, wheel-line, in-line, fixed line or other sprinkler system. They will survive in oxygen rich water; such as agitating water, but may "drown" if you leave them in standing water for more than 24 hours. "Watering in" will help "Field Guardian Nematodes" migrate to the protected area within root zone.
Use these in combination with Milky Spore, and you'll rid yourself of grubs very quickly. The Nematodes go to work as soon as they hit the soil. Add the Milky Spore and you're covered for up to ten years!
*Shipped Second Day air. Some one will have to be there to sign for them to guarantee their viability so choose an address where some one will be there to do that. Please read this entire page and read your instructions ahead of time by clicking here.
• Steinernematids and heterorhabditids have similar life histories. The non-feeding developmentally arrested infective juvenile seeks out insect hosts and initiates infections. When a host has been located, the nematodes penetrate into the insect body cavity, usually via natural body openings (mouth, anus, spiracles) or areas of thin cuticle. Once in the body cavity, a symbiotic bacterium (Xenorhabdus for steinernematids, Photorhabdus for heterorhabditids) is released from the nematode gut, which multiplies rapidly and causes rapid insect death. The nematodes feed upon the bacteria and liquefying host, and mature into adults. Steinernematid infective juveniles may become males or females, where as heterorhabditids develop into self-fertilizing hermaphrodites although subsequent generations within a host produce males and females as well. The life cycle is completed in a few days, and hundreds of thousands of new infective juveniles emerge in search of fresh hosts.
• Thus, entomopathogenic nematodes are a nematode-bacterium complex. The nematode may appear as little more than a biological syringe for its bacterial partner, yet the relationship between these organisms of one of classic mutualism. Nematode growth and reproduction depend upon conditions established in the host cadaver by the bacterium. The bacterium further contributes anti-immune proteins to assist the nematode in overcoming host defenses, and anti-microbials that suppress colonization of the cadaver by competing secondary invaders. Conversely, the bacterium lacks invasive powers and is dependent upon the nematode to locate and penetrate suitable hosts.
Special Instructions for Your Order.
· Water the Nematodes into a thoroughly moist soil in the evenings as the nematodes are very sensitive to sunlight. Water well afterwards too.
