Product Application

As a Defoliant (Primary Agricultural Use)

Crop:​ Cotton

Purpose:​ Applied pre-harvest to promote leaf dehydration and abscission. This concentrates boll opening, reduces leaf trash in harvested lint, facilitates mechanical picking, and can improve the percentage of first-quality cotton.

Timing:​ Typically applied when 60-70% of bolls are open or about 20 days before anticipated first frost. Requires adequate temperature and light post-application.

As a Fruit Set Agent / Enhancer

Crops:​ Table grapes, Melons (e.g., muskmelons), Kiwifruit, Cucumbers, some berries.

Purpose:​ Increases fruit set, promotes uniform cell division and expansion, enhances fruit size, weight, and yield.

Method:​ Usually involves dipping, spraying flower clusters, or spraying individual young fruits​ at a very specific phenological stage. CRITICAL: Concentration, timing, and method must be precise to avoid severe phytotoxicity (malformed, cracked fruit).

As a Chemical Fruit Thinner

Crops:​ Apples, Pears, Peaches.

Purpose:​ Thins excess fruitlets to improve size and quality of remaining fruit and regulate cropping (reduce biennial bearing).

Risk:​ Technique is highly sensitive to variety, crop load, and weather; can lead to overthinning or underthinning.
