A commercial pollination agreement isn't just a delivery date and a price — it is a set of clauses that allocate risk between beekeeper and grower. Two of the highest-stakes clauses are the hive stocking rate (how many colonies per acre the grower is paying for) and the no-spray buffer, a window of hours before, during and after bloom in which the grower must not apply pesticides toxic to bees while hives are on site.
Many real-world pollination contracts specify the no-spray buffer in exact hours (often 48–72h before and after hives are present) precisely because label directions alone rarely account for a rented colony's foraging schedule — the contract, not the pesticide label, is what actually protects the beekeeper's bees.
An interactive 3D orchard paired with a contract timeline: set the hive stocking rate, contract price and a no-spray buffer clause, then test whether a grower's chosen pesticide day breaches the agreement.
The no-spray buffer clause carves out a protected zone of days around the bloom window; a shaded band on the 3D timeline shows exactly which days are off-limits, and pressing "Apply pesticide" resolves whether the chosen day falls inside it.
Adjust hive stocking rate and price to see the rental bill change, widen or narrow the no-spray buffer, pick a day for the grower's pesticide application, then press "Apply pesticide" and watch the duster plane cross the orchard — bees drop if the buffer is breached, and an estimated liability appears.
Because pesticide labels alone rarely account for a rented colony's foraging schedule, well-drafted pollination contracts spell out the no-spray buffer in exact hours — it's the contract, not the label, that ultimately protects the beekeeper's bees.
