Thyme Guard

This unique product uses a hefty dose of Thyme Oil for applications as a multipurpose pesticide, fungicide and bactericide. Thyme ( Thymus vulgaris ) Oil is well known to be highly effective for control of plant pathogenic bacterium, fungi and viruses, as well as sucking insects.

How does it work? With plant pathogens, it attacks and breaches their cellular membranes, causing their death. As an insecticide, it works as an endocrine disruptor, suffocant and repellent. None of these modes of action will cause the pest to develop resistance and Thyme Guard is 100% biodegradable, so you can use it as often as you need to without worry.

Key Features:

  • Thyme Guard can be mixed with other products; however, best results are achieved if you use them in rotation with each other.
  • Can be used at any time in the growing cycle, including harvest day.
  • Registered for Organic Agriculture by the Washington State Dept. of Agriculture ( WSDA Registered ).
  • Will not harm beneficials or pollinators, but it is best to avoid applying Thyme Guard when bees are actively foraging and/or right after you have released beneficials.
  • Can be used to control the devastating Asian Citrus Psyllid and Citrus Greening/Huanlongbing disease.
