Commercial Citrus Stop Drop

Reduction of Pre-Harvest Drop

Selective, Systemic growth regulator acts as a synthetic Auxin. Moves mainly in the plant via the phloem. Effectively reduce pre-harvest drop of certain crops and for the control of colouring of citrus fruit.

Profile

2,4-D Dimethylamine Salt was use as a plant growth regulator began shortly after its introduction—from the mid-1940s to early 1950s
It acts as a synthetic auxin, mimicking the natural plant hormone indole-3-acetic acid (IAA). When absorbed through leaves or stems, it disrupts normal hormone balance and overstimulates auxin pathways, causing uncontrolled cell elongation, abnormal gene expression, and disruption of vascular tissue development
This leads to unregulated growth, twisting, bending, and ultimately growth suppression or death of sensitive tissues
In regulated low-dose applications, this auxin-like activity is harnessed to control sucker growth, modify shoot development, or influence fruiting responses depending on the crop

Key Features & Benefits

Synthetic auxin formulation (100 g/L): Mimics natural plant hormones to regulate growth by reduction of pre-harvest drop and control of colour
Selective growth regulation: Controls unwanted shoot and sucker growth without harming the main crop when used at recommended rates
Improve fruit quality: Helps improve fruit set, uniformity, Retardation of colouring and delay aging to rind especially in Navel Oranges, Mandarins & Grapefruits
Easy-to-use dimethylamine salt: Highly soluble and readily absorbed for consistent and reliable performance
Versatile crop application: Suitable for pome fruits, citrus, grapes, and other horticultural crops requiring targeted growth control
