  • Greenhouse Hybrid nematode blend includes a mix of Steinernema carpocapsae and Steinernema feltiae.
  • Roughly 1 million nematodes per 1000 square feet of soil medium.
  • For every square foot you will need .66 gallons of water as a carrier to saturate a potting medium or soil 2” deep. Water is the carrier for nematode applications and may be applied through irrigation lines or high volume, low-pressure sprayers. Do not exceed 200 psi and remove all intake injectors and openings smaller than 0.5 mm and all filters less than 50 mesh or finer. 
  • Nematodes may be stored in the refrigerator until you are ready to apply them.

Orders for Greenhouse Blend Nematodes must be received by noon on Friday for shipment the following week.  If the deadline is past, please call us and we will help you find a solution ASAP. (360) 656-6680
