Characteristics and Differences of Brassinolide, DA-6, and Sodium Nitrophenolates in Cold Seasons
1. Differences in Characteristics and Dosages
When addressing the challenges of crop growth in autumn and winter, we often encounter plant growth regulators such as brassinolide, DA-6, and sodium nitrophenolates. While these agents all promote crop growth, their properties and recommended dosages vary. Different regulators have different promoting effects and dosages. Brassinolide, DA-6, and sodium nitrophenolates each have their own characteristics and optimal concentrations.
Brassinolide Characteristics
Brassinolide, as an endogenous plant hormone, was developed by plants over a long period of evolution to adapt to the natural environment. Therefore, it has a high affinity for plants and rarely causes phytotoxicity. Brassinolide is often used to break seed dormancy, increase germination rates, improve crop quality, enhance stress resistance, and increase yield. Its effectiveness is even greater when used in combination with potassium dihydrogen phosphate and amino acid fertilizers, not only regulating and accelerating plant growth but also mitigating phytotoxicity to a certain extent. The recommended dosage is no more than 10 grams per 15 kg of water, with an optimal dosage of approximately 5-8 grams for significant results.
Diethyl aminoethyl hexanoate (DA-6) Properties
Diethyl aminoethyl hexanoate, as a synthetic growth regulator, is fundamentally different from brassinolide. It primarily regulates the balance of endogenous hormones in plants, enhancing photosynthesis by boosting enzyme activity, and thereby improving certain specific abilities of crops. This property enables it to perform well even in low-temperature environments. For example, before the onset of the cold season, combining diethyl aminoethyl hexanoate with potassium dihydrogen phosphate can effectively improve the frost and cold tolerance of overwintering crops such as wheat. The recommended dosage is 5-10 grams of diethylaminoethyl hexanoate per 15 kg of water for significant results.
Sodium nitrophenolates (Atonik) Properties
Atonik, a plant cell activator, is a growth regulator carefully synthesized by scientists to enhance specific plant abilities. Its core ingredients include 98% Sodium 5-Nitroguaiacolate, 98% Sodium Ortho-Nitrophenolate, and 98% Sodium Para-Nitrophenolate. Unlike Brassinolide and DA-6, Atonik primarily promotes chlorophyll and protein synthesis, thereby increasing crop yields. When plant leaves begin to yellow, using urea in combination with sodium nitrophenolates can quickly restore green color and increase chlorophyll content. However, when using sodium nitrophenolate, the dosage should be carefully controlled: 0.1-0.3 grams per 15 kg of water is recommended.
2. Differences in Applicable Temperature Environments
The effectiveness of the three regulators varies with temperature, so consider the effects of temperature when selecting one. The effectiveness of sodium nitrophenolates is affected by temperature. Use within the appropriate temperature range to fully promote plant growth; however, excessively high or low temperatures may affect its effectiveness. Therefore, when using sodium nitrophenolate, it is important to select the appropriate temperature environment to ensure its effective growth promotion.
Suitable Temperatures for Diethyl Aminoethyl Hexanoate
Diethyl aminoethyl hexanoate performs well in low-temperature environments and has a wide adaptability, maintaining high activity even at lower temperatures. Therefore, it is a suitable choice for both overwintering crops and crops planted in early spring.
Suitable Temperatures for Sodium Nitrophenolates (Atonik)
Sodium Nitrophenolates (Atonik) is less active at low temperatures and is best used at temperatures above 15°C. Its activity gradually increases with increasing temperatures, leading to a more pronounced effect.
Suitable Temperatures for Brassinolide
Brassinolide is most effective in temperatures between 15°C and 30°C. If the temperature is below 15°C, DA-6 is recommended instead. At temperatures above 30°C, Atonik or Sodium Nitrophenolates are more suitable options.
3. Differences in Longevity
Brassinolide, DA-6, and Sodium Nitrophenolates have different longevity periods, with DA-6 having the longest and Sodium Nitrophenolates the shortest. Choosing a growth regulator based on your needs requires careful consideration. DA-6 has the longest longevity, approximately 30 days, and its onset of action is also moderate. Brassinolide has a slightly shorter longevity, but the fastest onset of action, reaching approximately 25 days. Sodium Nitrophenolates has the shortest longevity, approximately 15 days, but its onset of action is relatively slow.
4. Differences in Mitigating Crop Injury
Brassinolide, DA-6, and Sodium Nitrophenolates can all be used to mitigate crop injury when combined with potassium dihydrogen phosphate or amino acid foliar fertilizers. Choose a growth regulator based on the severity of the injury, paying particular attention to the effects of different growth regulators when combined with potassium dihydrogen phosphate or amino acid foliar fertilizers. For example, when improper use of insecticides and fungicides causes damage, sodium nitrophenolates or brassinolide are effective mitigation measures. For damage caused by hormones or herbicides, diethylaminoethyl ester is recommended.
5. Practical Application Methods Vary
When applying these growth regulators to mitigate crop damage, the actual application method varies depending on the specific situation. This involves multiple factors, such as the combination of regulators, the concentration used, and the timing of application, all of which require flexible adjustments based on the specific situation. Adjusting the regulator application method, including concentration and timing, based on specific needs can improve efficacy.
For example:
Promoting seed rooting and germination: Brassinolide is recommended, as it effectively promotes rooting and germination, thereby increasing germination rates.
Improving fertilizer utilization: Sodium nitrophenolates are excellent, stimulating rooting and promoting seedling growth, thereby improving overall fertilizer utilization.
Mitigating crop damage: Brassinolide is generally a good choice. As an endogenous plant hormone, it has a high affinity and can quickly restore crop growth.
