1、Optimal Timing for Spraying Brassinosteroids on Crops

Spraying at this stage effectively boosts crop yield. During peak growth periods (e.g., hot summers), spraying also enhances drought tolerance and disease resistance.

2、Optimal Use of Brassinosteroid in Crop Spraying

Timing of Application: Apply brassinosteroid in the morning or evening to avoid intense midday sunlight. Additionally, refrain from spraying during rainy weather or strong winds, as this may reduce effectiveness.

3、Brassinosteroid improves resistance to phosphorus deficiency stress

Brassinosteroid (BR) plays a crucial role in plant growth, development and response to abiotic stress. However, the mechanism by which BR regulates the response of potato plants to phosphorus deficiency stress is still largely unknown.

In a different study, spraying the potato plants with BL (10 −2 –10 −4 ppm) three times, at the interval of 1 week increased the mean tuber weight from 100 to 145 g mediated by changes in abscisic acid and ethylene level in the treated tubers (Korableva et al. 1998).

Designed Manipulation of the Brassinosteroid Signal to Enhance Crop

Effective manipulation of the BR signal and avoidance of side effects are required to enhance yield in different crops. Application of BR by spraying at specific developmental stages can enhance crop yield, but this method is impractical for use on a large scale.

Brassinosteroids have a number of unique properties, including the ability to increase productivity and plant resistance to biotic and abiotic stressors in extremely low concentrations. The steroid hormones used in agriculture are chemically synthesized.

Likewise, BS application increased the size of potato tubers (Savelieva et al., 1997). Moreover, spraying the potato plants with BL (10 −2 –10 −4 ppm) three times, at the interval of one week increased the mean tuber weight from 100 to 145 g.

Optimal Timing for Brassinosteroid Application in Beekeeping

The optimal time for brassinosteroid application is during the early growth stage of plants, typically starting about one week after sowing. At this stage, roots begin to develop, and their absorption capacity is stronger, resulting in better efficacy.

Brassinosteroid is a plant growth regulator primarily used to promote plant growth and increase yields. For potatoes, the best times to apply brassinosteroid are before planting, during the growth stage, and before harvest. Below, I will detail the spraying methods and precautions for each period.

I. Pre-Planting Spraying

Spraying before planting aims to enhance potato root development and improve nutrient absorption from the soil. About one week before planting, mix an appropriate amount of brassinosteroid with water and evenly spray it onto the soil around the potato roots. This creates a favorable growth environment, allowing the potatoes to recover quickly after planting.

Spraying Method:

1. Choose a sunny, windless day to avoid rain washing away the solution and reducing effectiveness.
2. Use a sprayer to apply the brassinosteroid solution evenly to the root area. Avoid overapplication, which may burn the roots.
3. Water promptly after spraying to help the solution penetrate the soil and stimulate root growth.

II. Growth Stage Spraying

Spraying during the growth stage promotes potato development and boosts yields. Apply the solution periodically throughout the growth cycle to maintain healthy plants.

Spraying Method:

1. Time applications based on growth conditions. Spring and autumn, when growth is vigorous, yield the best results.
2. Use a sprayer to apply the solution evenly to the stems and leaves. Avoid overapplication, which may disrupt normal growth.
3. Water immediately after spraying to ensure the solution reaches all plant parts and enhances growth.

Precautions:

1. Control dosage carefully to avoid damaging plants.
2. Monitor plants closely after spraying and address any abnormalities promptly.
3. Apply on sunny days to maximize effectiveness; avoid rainy or cloudy weather.

III. Pre-Harvest Spraying

Spraying before harvest protects potatoes from pests and diseases while improving quality. Apply a thorough spray about one month prior to harvest.

Spraying Method:

1. Choose a sunny, windless day to prevent rain from reducing efficacy.
2. Use a sprayer to apply the solution evenly to the potato surfaces. Avoid overapplication, which may affect appearance.
3. Water promptly after spraying to help the solution penetrate and strengthen disease resistance.

Precautions:

1. Strictly control dosage to prevent plant damage.
2. Observe plants closely after spraying and resolve issues promptly.
3. Apply on clear days; avoid damp or overcast conditions.

potatoes require brassinosteroid sprays at different growth stages, with adjusted concentrations and timings for optimal results. Follow proper dosage, application methods, and precautions to maximize growth and yield potential.
