Haven® Stress Manager for Crop Heat & Sun Damage Protection


Haven plant stress reduction

Protect Plants From Heat Stress

Haven is an abiotic stress manager that helps crops dissipate excess heat and moderates solar radiation. This process keeps plants at a temperature optimal for heat and sun damage protection. Lowering temperatures during hot periods helps protect plants from stressors that may impact photosynthesis. Multi-year field trials have shown that Haven-treated crops experience increased marketable yield compared to untreated controls when applied at labeled rates.

Haven’s active ingredient, Stearyl alcohol, is plant-derived. The formulation is easy to mix and apply without leaving visible residue (MRL exempt).

How your crops benefit from Haven


Haven helps protect plants from abiotic stressors like extreme temperature and sun exposure. Multi-year field trials have shown that Haven-treated crops experience increased marketable yield compared to untreated controls. Trial highlights:

  • Increased photosynthetic activity: Wine grapes with higher °Brix throughout the season and an 18% average yield boost.
  • Less abiotic stress damage: Fresh grapes with 50% less sun damage and, on average, 59 more boxes per acre.
  • Strong Return on Investment: Marketable nut increase by 14% for a 4:1 ROI
  • Higher Marketable Yield: 6-28% yield increase for high tunnel tomatoes
  • Market Access Opportunity: MRL exemption for easier export and higher quality pack-out (less scrubbing!).

Mode of Action


Haven dissipates excess heat to keep leaf temperatures optimal for abiotic stress protection. Throughout the season, Haven-treated plants experience relief from abiotic stressors that impact photosynthesis. Haven is easy to mix and leaves no visible residue, simplifying application and post-harvest processing.


Haven Efficacy


When two to four applications are sprayed on crops generally starting at early fruit/nut set, Haven has reduced sun stress and increased yields for almonds, walnuts, grapes, citrus, tomatoes, corn, wheat and turf.


In Trials


Haven treated almonds experienced a 17.4% increase in tons per acre over the untreated plots.


Art of Use


The following best use practices should be kept in mind to effectively use Haven:

In general, 2 to 4 applications of Haven should be made at a rate of 0.6-0.9% v/v. Treat based on crop growth stage at a 2 to 4 week interval. Always refer to label for crop-specific instructions.

  • Perennial crops (i.e. trees, vines) benefit from 3 to 4 applications of Haven at 2.5 quarts per acre in 100 gallons of water (0.6% v/v). For maximum efficacy in vines, begin spraying by early fruit set; in walnuts and almonds, begin spraying at bloom or petal fall, respectively.
  • Field trials in annual crops have demonstrated stress-reduction yield benefits when Haven is applied once at flower initiation at a rate of 0.9% v/v. An additional application can be made at early fruit set.
