NEMAforce™ HB is a biological control targeted to fight specific pests. The beneficial nematodes attack, disrupt, and kill harmful insect larvae in the potting media within 24-48 hours – preventing damage to plants and helping fight off disease by re-establishing a strong and vigorous root system. It is compatible with all other beneficial organisms, including RootShield PLUS+ G and WP, making it an excellent tool in your integrated pest management program.

Application Rate Recommendations for Heterorhabditis bacteriophora - NEMAforce™ HB:

• Preventative to Low Infestation: 50 million package of nematodes treats up to 2,000 sq. ft. (500 million package size also available).
• Low to Moderate Infestation: 100 million to 1 billion nematodes per acre (2.5 billion nematodes per hectare)
• Moderate to Heavy Infestation: 250 million to 2 billion nematodes per acre (6.25 billion nematodes per hectare)

Pre-Application:

• Scout for early detection.
• Adequate soil moisture must be present and maintained for 2 weeks to aid nematode mobility.
• Soil temperature of 50-80ºF (74ºF optimum) is necessary for nematode activity.
• DO NOT FREEZE. Unopened products are to be refrigerated and used prior to the expiration date on the container. The expiration date on the box is month/day/year format (mm/dd/yy).
• To avoid blockages, all screens should be removed and the spray nozzle opening should be at least 1mm (1,000 microns).
• The maximum sprayer pressure is 150 psi.
• Nematodes are very sensitive to UV light. DO NOT apply in direct sunlight; apply on a cloudy day or late in the afternoon.

How-To Use Heterorhabditis bacteriophora - NEMAforce™ HB For Best Results:

• Prepare and apply out of direct sunlight.
• Empty the contents of the package into a bucket containing about 1 gallon of cool (60º-75ºF) water, then stir.
• Let the entire solution soak for 5 minutes. Stir again thoroughly, then transfer the contents into the spray tank and fill to the desired level.
• To avoid blockages, all screens should be removed and the spray nozzle opening should be at least 1 mm (1,000 microns).
• The maximum sprayer pressure is 150 psi.
• Continuous agitation is necessary to prevent the nematodes from settling out.
• Evenly spread the solution over the ground area to be treated.
• Moderately water-in after application to move the nematodes off the foliage and into the ground. Avoid washing the nematodes through the soil.
• Keep the soil moist (not saturated) for 2 weeks.
• Apply NEMAforce™ HB as soon as possible after receipt.
• Store NEMAforce™ HB in a refrigerator at 36-40°F (2-4°C) until use.
• Do not freeze NEMAforce™ HB.
• Apply NEMAforce™ HB with sufficient water to ensure uniform soil or potting media coverage.
• Irrigate before and after application to move NEMAforce™ HB into the soil or potting media.
• Maintain adequate soil moisture for at least two weeks after application.
• Avoid applying NEMAforce™ HB during the heat of the day or when soil temperatures exceed 90°F (32°C).
• Do not apply NEMAforce™ HB to dry soils or potting media.
• Do not apply NEMAforce™ HB through chemigation systems.

Compatibility:

• Not compatible with many organophosphates or carbamates.

Features & Benefits:

Control root-feeding grubs and larvae with an application of NEMAforce™ HB. The beneficial nematodes, Heterorhabditis bacteriophora, will actively seek out the grubs and larvae to infect them. Feeding subsides and the host will die within a few days.

• Exempt from EPA regulations; 0-hour REI
• Fast, effective biological control
• Easy and user-friendly to apply
• Insects stop feeding and die within 24-48 hours
• Ensures your greenhouse crops have the most vigorous root system possible
• Nematodes release bacteria inside the insect host that causes septicemia and death
• Beneficial bacteria multiply rapidly inside the insect host converting tissues into food for nematodes
• The next generation of nematodes leaves the insect host to actively seek new hosts

Mode of Action:

• The nematodes in NEMAforce™ HB actively search for insect larvae and enter through natural openings.
• As the nematodes feed on the host body, they excrete a specific bacteria, that is toxic to larvae.
• The bacteria multiply very rapidly and convert the host tissue into products that the nematodes use as a food source.
• Larvae die within a few days, the host turns orange-red to red-brown.
• The next generation of nematodes leave the old host and actively seek out new ones.
