What is it?
Technically, “Guardian” is a sub strain of the Steinernematidae family, and “Lawn Patrol” is a sub strain of the Heterorhabditatid family. Beneficial, entomogenous (insect parasitic) nematodes. Nematodes are one of the most abundant groups of living creatures in the world, with species ranging from pests of plants and animals to beneficial species like this one. This microscopic creature can survive in oxygen rich water or in the root zone of your plants. “Guardian / Lawn Patrol” will not harm plants, animals or humans.

What does it attack? – Click Here to see a list of specific insects.
“Guardian / Lawn Patrol Nematodes” actively searches for insects, insect pupa and insect larvae in places that are constantly moist. Among the more than 250 susceptible insect pests are: cutworms, corn rootworms, strawberry root weevils, European corn borers, white grubs, sod webworms, termites, and many other insects that spend part of their life cycle in the root zone. We use “Guardian / Lawn Patrol Nematodes” to control thrips, “fungus gnats” (relating to several thousand species of flies in the same family ) and other root zone pests. “Guardian / Lawn Patrol Nematodes” do not kill other types of nematodes. We have been rearing beneficial nematodes since 1986. We have located a sub-strain we feel is far superior to any used in the past. Under ideal conditions, “Guardian” can survive 90 days or more without a host insect. Once “Guardian” locate and enter a host, it will kill the host, reproduce within it and the offspring will exit in search of more host insects; repeating the cycle.

Produced by Hydro-Gardens
Hydro-Gardens raises “Guardian / Lawn Patrol Nematodes” to insure freshness, quality and prompt shipping to our customers. They are reared on ‘insect hosts’. Only those “Guardian / Lawn Patrol Nematodes” that promptly kill host insects, are selected for reproduction. We know they work, because we document their behavior. If “Guardian” can enter a host insect, they will kill the insect within 24 – 48 hours, then reproduce within the insect, thus providing long-term control.

“Guardian / Lawn Patrol Nematodes” are usually applied in the evening, directly into the soil or growing media, however some growers spray their foliage in the evenings and report successful results against some insects on their foliage by using All Season Oil to protect the nematodes from desiccation. “Guardian” can be temporarily stored in a refrigerator at 40o-50oF. You should mix the package into one gallon of water to create a concentrate. “Guardian” can withstand pressures up to 300 PSI, therefore, you can apply them using your injector system, or dilute them with more water and use a pump sprayer, hose-end sprayer, watering can or pail. They will survive in oxygen rich water; such as nutrient film technique (NFT) systems, but may “drown” if you leave them in standing water for more than 24 hours. “Watering in” will help “Guardian / Lawn Patrol Nematodes” migrate to the protected area within root zone. Great for the greenhouse or outdoors!!

Releasing 1 million of these nematodes over 2,000 ft2 works out to approximately 500 nematodes per ft2. As a preventative, they should be applied every 60 days to greenhouse crops. For outdoor applications, usually they should be applied in the early Spring as soon as the frost has gone out of the ground. Since they can survive for 60 – 90 days before finding a host, they will be in place as the insect activity increases with warmer temperatures.
