1、Brassinolide ameliorates the detrimental effects of arsenic in tomato

Brassinolide (Solarbio, Beijing, China) (0, 0.5, and 1 mg · L −1) was applied via spraying twice during the experimental period (the first application was conducted three days prior to the start of As treatment while the second was administered five days following the initiation of As stress).

2、How to use brassinolide

Usage: Apply 0.01mg/L brassinolide foliar spray during tomato seedling stage, 20-30L per acre, or 0.05mg/L brassinolide foliar spray during field period, 50L per acre, spray twice every 7-10 days, 2-3 times in total.

3、Application on tomatoes

From flowering period to fruit enlargement period: Spraying 0.1mg/L (4kg of water per grain) on the leaves can significantly increase the weight of the fruit, enhance the plant's ability to resist low temperatures, and reduce the damage of diseases.

4、How often is Brassinolide sprayed?

So how often is Brassinolide sprayed? Is there a function? When can it not be sprayed? Let's find out. How often is Brassinolide sprayed? Generally recommended use periods are: spraying once at the beginning of flowering, young fruit, and fruit expansion.

5、Revealing the Specific Regulations of Brassinolide on Tomato Fruit

Brassinolide (BR) is a plant growth regulator that is known to decrease the susceptibility of fruit to CI. In this study, transcriptome, metabolome, and proteome analysis revealed the regulation mechanism of BR treatment in alleviating tomato fruit CI.

The role of brassinosteroids (BRs) in enabling plants to respond effectively to adverse conditions is well known, though the precise mechanism of action that helps plants cope with arsenic (As) toxicity is still difficult to interpret.

Chinese Researchers Discover Brassinolide’s Arsenic

The study, which involved spraying tomato plants with varying concentrations of brassinolide under arsenic stress, revealed some astonishing results. “Brassinolide spray protected the photosynthetic system and helped plants grow better under arsenic stress,” Emamverdian explains.

Brassinolide ameliorates the detrimental effects of arsenic in tomato

The role of brassinosteroids (BRs) in enabling plants to respond effectively to adverse conditions is well known, though the precise mechanism of action that helps plants cope with arsenic (As) toxicity is still difficult to interpret.

How to use brassinolide?

Choose an appropriate concentration. A concentration of 1200 times can be selected in the north and 1000 times can be selected in the south. Too high or too low a concentration is not conducive to increasing yield.

1. Application Frequency

The frequency of brassinolide application generally depends on specific agricultural production conditions, crop type, and expected yield targets. In modern agriculture, usage is often adjusted according to crop growth stages and needs. For example:

• Early growth stages: May require more frequent applications.
• Before harvest: Applications may be reduced.

2. Dosage

The dosage of brassinolide should be tailored to the crop type and growth stage. Excessive use may accelerate plant growth excessively, compromising fruit quality and yield. Always follow product instructions or consult professionals for appropriate dosing.

3. Combination with Other Pesticides

In some cases, brassinolide may be used alongside other pesticides for enhanced effects. this should only be done under professional guidance to ensure safety and efficacy.

4. Environmental Protection

As a chemical formulation, brassinolide may impact the environment during use. Prioritize eco-friendly practices to minimize pollution, such as avoiding runoff and adhering to recommended application methods.

5. Safety Precautions

• Follow safety regulations and operational protocols (e.g., avoid direct contact with food, prevent inhalation of dust).
• Use personal protective equipment (PPE) like gloves and masks.

6. Storage and Management

Store brassinolide in a cool, dry, and well-ventilated area, away from heat and open flames. Ensure containers are sealed to prevent leakage or volatilization.

7. Additional Cautions

• Avoid combining with non-steroidal anti-inflammatory drugs (NSAIDs), as interactions may occur.
• Pregnant or breastfeeding individuals should refrain from handling.
• Allergic individuals: Perform a skin sensitivity test before use.
• Children: Supervised use is required.

The application frequency and dosage of brassinolide should be adjusted based on specific circumstances. Always comply with relevant laws, standards, and safety guidelines to effectively promote plant growth and development.
