COMMERCIAL APPLICATOR SUGGESTIONS TERRANEM™ is the product of choice for turf care professionals across Canada. The following information will be of value to professionals providing larger scale applications. Product sizes available: TERRANEM™ is available in a 500 million nematode package size for commercial lawn care companies, landscape contractors, ground maintenance professionals etc. The 500 million package contains 2 bags of 250 million nematodes, which can be mixed and used separately. 500 million nematodes are sufficient to treat up to 30,000 sq. feet (2,787 sq. m.) depending on the level of infestation. Preferred water temperature for applying nematodes: Water temperature of 14 to 20° C (50 - 70° F) is ideal for nematode application. If necessary water can be put in the tank the night before application and the nematodes mixed and added in the morning just before planned application. Cooler water will not harm the nematodes, just delay their performance until the water warms up. Effect of chlorine in water: Normal concentrations of chlorine (up to 0.1 % active chlorine) do not normally affect the performance of TERRANEM™. Volume of water required for application: Proper application of beneficial nematodes requires a carrier volume of 2 – 5 gallons of water (7.6 – 18.9 litres) per 1,000 square feet of treatment area. Pre and post irrigation is strongly recommended. Application on a rainy day is ideal. Proper droplet size: There is no specific recommendation for a correct droplet size but it should not be too small to avoid the possibility of the nematodes drying up and dying after application. Tank agitation requirements: We recommend that TERRANEM™ be agitated in some form while in the spray tank. In a large spray tank a mixer or circulating pump will work well. By agitating the solution the nematodes are kept from sinking to the bottom of the tank. Pump selection: Diaphragm, centrifugal or jet pumps can all be used for application of beneficial nematodes. However, centrifugal pumps will generate heat which can be detrimental to nematode populations. Use care not to run this type of pump too long at one time. Spray nozzle opening: The spray nozzle opening should be a minimum of 0.5 mm (500 micron). Proper pressure: Use a maximum pressure of 5 bar (72psi) on spray boom or pistol.
