Preventing Mesquite Pod Production: Florel Growth Regulator

Stop Pods by Stopping Flowering

Mesquite (Prosopis) pods form from fertilized flowers. Florel® (ethephon) applied at bloom inhibits fruit set by releasing ethylene, a natural plant hormone that aborts developing ovaries.

Florel Application Protocol

• Timing: Mid to full bloom (critical—before fruit set).
• Rate: 1 quart per 10 gallons water (3 oz/gal).
• Coverage: Wet foliage thoroughly—do not spray to runoff.
• Volume: Depends on tree size; ensure complete canopy coverage.

Non-Chemical Alternatives

• Hand-remove flowers: Feasible only on small trees.
• Remove tree: Only 100% guarantee.

Practical Considerations

• Mesquites often large—spray coverage difficult.
• Annual treatment required.
• Ethephon degrades rapidly—timing window is narrow (days).

Decision Framework

If tree is small and pod nuisance high → Florel may be worth it. If large tree → cost/effort rarely justified. Consider replacement with podless cultivar (e.g., 'Maverick' honey mesquite) if replanting.
