Product Details
Product Characteristics:
This product is a plant growth regulator formulated from choline chloride and naphthaleneacetic acid (NAA). Choline chloride enhances the photosynthetic rate and increases the content of carbohydrates, proteins, and chlorophyll in plants. NAA promotes root growth, increases fruit set, prevents fruit drop, and alters the ratio of female to male flowers. When used at recommended dosages, it effectively regulates the growth of ginger.
Formulation: 18% Choline Chloride + NAA Wettable Powder (1% NAA + 17% Choline Chloride)
Toxicity: Low toxicity
Registered Crops: Garlic, ginger, onion
Application Techniques
Garlic
In North China, apply around March 20 (early March in Southwest China). Foliar spray with a solution concentration of 237–480 mg/L, 2–3 times at intervals of 10–15 days. This treatment enhances superoxide dismutase (SOD) activity, promotes cell division and expansion, extends the functional lifespan of leaves, and improves photosynthetic efficiency. It accelerates the transport of nutrients to the bulb, increases the accumulation of starch, protein, and sugars, promotes early swelling of axillary buds, enlarges small cloves, increases the proportion of large and medium-sized bulbs, and boosts overall yield.
Ginger
At the "three-branch" stage (three-shoot stage), apply a foliar spray with a solution concentration of 180–420 mg/L, 2–3 times at intervals of 10–15 days. This results in larger ginger rhizomes with thinner skin and tender flesh, improving both quality and yield while imparting characteristics of tenderness, freshness, aroma, and crispness.
Onion
At the early stage of bulb expansion, apply a foliar spray with a solution concentration of 300–360 mg/L, 2–3 times at intervals of 10–15 days. This significantly promotes bulb expansion, increases bulb diameter, inhibits premature bolting, and boosts onion yield.
Precautions
① Maximum of 3 applications on garlic, ginger, and onion; pre-harvest interval of 10 days.
② Protect from direct sunlight and rain during storage; ensure good ventilation.
