Application of Auxin Cloprop (3-CPA) in South Africa

                               Application of Auxin Cloprop (3-CPA) in South Africa   South Africa’s diverse climates—Mediterranean (southwest: 15–25℃, wet winters/dry summers), savanna (northeast: 20–30℃, distinct wet/dry seasons), and semi-arid (central: 25–35℃, low rainfall)—support key crops like table grapes, citrus, avocados, tomatoes, and stone fruits. As a synthetic auxin, Cloprop (3-CPA) addresses region-specific challenges such as summer heat-induced fruit drop, uneven sizing, and post-harvest waste, critical for the country’s export-focused agriculture. Below is its application across major crop types.   1. Fruit Thinner 3-CPA to use on Table Grapes (Western Cape: Stellenbosch, Paarl) Application Approach: Single foliar spray. Prepare a 15–20 ppm Cloprop solution and target grape clusters, focusing on the base of young berries (3–5 mm diameter) and cluster stems. Use low-pressure sprayers with fine nozzles to avoid damaging delicate grape skins, which are vital for export q…
