                          How to use Cloprop (3-CPA) in South America   Usage of Cloprop (3-CPA) in South America South America’s diverse climates—tropical (Amazon Basin), subtropical (Southern Brazil), and semi-arid (Argentine Pampas)—support key crops like apples, pineapples, tomatoes, citrus, and peppers. Cloprop (3-CPA), as a synthetic auxin, addresses regional challenges (e.g., pre-harvest drop, uneven fruit set) across these crops. Below is its usage, organized by crop type.   1. Apples (Southern Brazil: Rio Grande do Sul; Argentina: Patagonia) Usage Method: Two foliar sprays. First, dilute 3-CPA to 15–25 ppm; second, use 25–35 ppm. Spray canopy evenly, focusing on fruit clusters and stems. Usage Time: First spray 10–14 days after full bloom (fruits 5–8 mm diameter); second spray 3–4 weeks before harvest. Timing aligns with Brazil’s apple blooming (September–October) and harvest (February–March). Effect: Reduces pre-harvest drop by 20–30% (critical for Patagonia’s dry harvest sea…
