Tenet WP

Tenet WP is an organic, water-soluble biofungicide that contains the naturally occurring strains of Trichoderma asperellum (ICC 012) and Trichoderma gamsii (ICC 080). These beneficial fungi will work aggressively to control soil-borne root and collar rot diseases by colonizing the root zone and the soil surrounding it. It forms a protective barrier that the pathogens cannot penetrate around the roots, but it will also attack the cell walls of any pathogens it comes in contact with. This type of enzymatic attack is not something the pathogen can usually withstand.

The two strains of Trichoderma found in Tenet WP begin working in different, yet complimentary, temperature ranges; T. gamsii germinates at 44.6°F and T. asperellum at 53.6°F. The optimal temperature range for activity of the two strains is 77°F to 86°F. This allows for an increased application timing window that allows for both early and late season plantings.

  • Removes the stress of fighting disease, leading to stronger and healthier plants.
  • Can be applied as often as needed, as determined by disease pressure.
  • Excellent choice for an IPM (Integrated Pest Management) program
  • 4-hour REI (Restricted Entry Interval) and 0-Day PHI (Pre-Harvest Interval)
  • Useful in managing chemical fungicide resistance.

Use & Instructions

Tenet is especially effective in preventing fungal pathogen attacks. For this reason, it is essential that it is applied and allowed to colonize an area before fungal pathogens have had a chance to establish.

  • Should be applied up to 7 days before planting to initiate soil colonization before the crop is planted and reapplied after planting.
  • For maximum effectiveness, apply 2 or more applications.
  • May be applied throughout the crop production cycle in order to maintain a high colonization of the root zone.
  • Do not apply by aircraft.
  • Apply when the soil temperature is at least 50°F (10°C).
  • Apply to moist soil or growth media, but not to saturated or waterlogged soil. Soil or growth media must remain moist after application to provide adequate control of soilborne fungal diseases.
  • May be applied to sterilized or fumigated soil but must be applied after the sterilizing agent or fumigant has dissipated.
  • Tenet WP has no curative effect and therefore is not effective against plants infected with disease at the time of application.
  • In case of applications on or to dry soils, pre-irrigate until soil is moist. Then irrigate again immediately after application.

Tenet WP is not compatible with the following fungicides: imazalil, dichloran, mancozeb, propiconazole, tebuconazole, thiram, and triflumizole. Do not tank mix with, or apply Tenet WP within 3 days before or after use of these products.

To prepare a suspension, combine 1 lb. of Tenet WP for every 1.25 gallons of water, and mix from time to time in order to promote the germination of conidia and obtain faster soil colonization. Subsequently, dilute the suspension in the amount of water needed per crop-specific applications on the label

Can be applied using the following application methods: cutting and bare root, broadcast, in-furrow, banded, greenhouse and nursery drench, and applications made via chemigation systems applied over the row or directed towards the desirable plants crown and rooting area, either before planting, at planting, or shortly after planting and promptly watered in. 



Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water when cleaning equipment or disposing of equipment washwaters or rinsate. This product may pose a risk to beneficial coleopteran (beetle) species.
