FAQ (Technical Q&A)
Q1: How does it differ from conventional fungicides in mode of action?
A: Brassinolide is a steroidal plant growth regulator, not a fungicide. It binds to cell surface receptors and triggers intracellular signaling that activates gene expression, promoting protein synthesis and cell division. Conventional fungicides directly kill or inhibit pathogens. Brassinolide enhances plant vitality and stress resistance, which indirectly improves disease tolerance.
Q2: What is the optimal concentration range for field application?
A: Brassinolide shows activity at extremely low concentrations (10⁻⁵ to 10⁻⁶ mg/L). Typical field formulations contain 0.001%–0.01% active ingredient. Over-dilution may reduce efficacy; over-concentration may cause excessive vegetative growth.
Q3: Can it be tank-mixed with fungicides?
A: Yes. Research shows co-application with fungicides such as pyraclostrobin improves disease control efficacy by eliciting plant innate defense responses. It can be tank-mixed with most neutral and acidic agrochemicals. Avoid mixing with strongly alkaline pesticides and fertilizers.
Q4: What crops have shown the best response to Brassinolide?
A: Registered uses include rice, wheat, corn, potato, tobacco, cotton, cucumber, tomato, pepper, citrus, grape, and kiwi. It is also used on medicinal materials and ornamental crops. It promotes cell division, root development, and chlorophyll synthesis.
Q5: How does Brassinolide affect stress tolerance in crops?
A: It enhances plant resistance to cold, drought, salinity, and heat stress by regulating osmotic balance and increasing protective enzyme activities such as peroxidase (POD) and superoxide dismutase (SOD). It also reduces abscisic acid (ABA) levels, helping plants maintain growth under stress.
Q6: What is the recommended application timing for Brassinolide?
A: Apply during early growth stages, flowering, and fruit-setting periods. For stress recovery, apply immediately after stress events. Spray in early morning or late afternoon to avoid high temperatures and direct sunlight. Rainfall within 1–2 hours after application may reduce efficacy.
Q7: Can Brassinolide be used to mitigate herbicide injury?
A: Yes. It can help alleviate herbicide phytotoxicity by promoting cell division and enhancing metabolic recovery. However, it should not be tank-mixed with herbicides directly. Apply as a separate treatment after herbicide injury symptoms appear.
Q8: How does Brassinolide interact with other plant hormones?
A: It exhibits strong interactions with auxins, cytokinins, and gibberellins. It can stimulate ethylene synthesis when applied with auxins and increase cytokinin levels by suppressing cytokinin oxidase gene expression. These interactions regulate plant growth and development synergistically.
Q9: What is the solubility and how should it be formulated?
A: It is soluble in methanol, ethanol, tetrahydrofuran, and acetone, with water solubility of approximately 5 mg/L. For formulation, dissolve in a small amount of organic solvent first, then emulsify or dilute with water. Typical formulations include soluble concentrates and emulsifiable concentrates.
Q10: How should Brassinolide Technical be stored?
A: Store in a sealed container in a cool, dry, dark place. Avoid moisture, heat, and direct sunlight. Keep away from strong alkaline substances. Shelf life is typically 2 years under proper storage conditions.
