Beneficial Nematodes

nematodesUSE: Beneficial Nematodes (BN) attack more than 230 kinds of soil dwelling and wood boring pests, such as flea larvae, white grubs, cutworms, corn root worms, strawberry weevils, gypsy moth larvae, cabbage root maggots, fungus gnat larvae, and many more.

RELEASE: BN may be released by spraying with water, mixing with mulch and applying directly to the soil or potting mix, or injecting into burrows. They may be used any time of year, as long as the ground is not frozen. Do not release in direct sunlight, as this will kill them. See directions for details.

COVERAGE: Will cover up to 2,000 square feet, but faster results are obtained with higher concentrations.

GENERAL INFORMATION: Beneficial Nematodes (Steinernema feltiae) are microscopic in size and cannot be seen with the naked eye. But the 7 million active units in each pint container will hunt down, penetrate, and kill most soil dwelling pests.

BN will remain effective for about 2 years, but annual applications are recommended. Refrigerate if not using immediately (35-40 degrees).

BN will attack over wintering adult insects, pupae, diapausing larvae, and grubs when they are in the soil, bark, or even ground litter.

BN do not affect humans, animals, or plants. They are completely compatible with beneficial insects such as ladybugs, lacewings, and Praying mantids and do not harm earthworms.

 

DIRECTIONS FOR USE

There are 3 ways to apply the Beneficial Nematodes (BN). Find your pest on the list at the bottom, then use the recommended treatment number.

#1 TOPDRESSING: Mix the entire contents of the container with 1/2 to 1 gallon cold water. Stir well and let stand for 1/2 hour. Stir again and add 5 to 6 quarts of vermiculite or peat moss or sandy humus.
Apply directly to affected areas. For new plants or transplants, apply around roots. Apply after sundown because sunlight will kill the BN. Water thoroughly after application because BN travel best in moisture.
#2 SPRAYING: Mix the entire contents of the container with 1/2 to 1 gallon cold water, stir well and let stand for 1/2 hour. Water the area to be treated before application. Use a watering can, hose sprayer, or pump sprayer. Always use the coarsest or highest rate setting to reduce damage to the BN.
Stir the mixture again and pour into the sprayer, filtering out the carrier as you go (Use a kitchen strainer or a piece of window screen.) Add the left over carrier to your soil. Always agitate the water while spraying and before pouring because the BN sink to the bottom.
Apply after sundown because sunlight will kill the BN. Water thoroughly after application because BN travel best in moisture.
#3 INJECTION: Mix the entire contents of the container with 1/2 gallon cold water. Stir well and let stand for 1/2 hour. Strain out the carrier (use a kitchen strainer or a piece of window screen), use the carrier in the soil, and let stand for another 1/2 hour. This allows most of the BN to sink to the bottom. Pour away the top water, saving the last pint.
Use an eye dropper or squeeze bottle to inject about a tablespoon of liquid into the burrow. Seal the hole if possible.
