Biohazard

Biohazard is one of the most explosive sell multipliers in the game at x157, sitting in the elite tier of growth mutations that can single-handedly turn a common crop into a serious cash payout. When a fruit carries this stat, its base sell price is multiplied 157 times before any rarity or weight scaling, which is why players treat any Biohazard drop as a keeper rather than a sell-on-sight.

The trigger condition is currently unrecorded in our data, listed only as Unknown, which fits the mutation's reputation as a rare, event-tied or chemically themed effect rather than something you farm reliably through normal weather cycles. Because of that uncertainty, you should not plan a garden around forcing it.

Where Biohazard truly shines is stacking. Growth mutations like this combine multiplicatively with environmental and rarity mutations, so a Biohazard fruit that also picks up a second high-tier mutation can balloon into one of your most valuable single harvests. Is it worth chasing? Not deliberately, since the trigger is opaque, but if one appears, never sell it raw, hold it, layer additional mutations, and cash out at maximum value.
