1、Insecticide containing brassinolide and thiamethoxam

The effective active components of the insecticide are brassinolide and thiamethoxam, wherein the weight ratio of brassinolide to thiamethoxam is (0.001-50): (1-800).

2、Impacts of Epihomobrassinolide and Thiamethoxam·Flutolanil

Epihomobrassinolide (EBR) is a natural product that widely participates in many the physiological activities of many plants. Thiamethoxam·flutolanil·azoxystrobin (TFA) has been registered as a seed coating agent in crop production.

3、Can thiamethoxam be mixed with other pesticides?

Thiamethoxam and pyrethroids have different modes of action, which means they can be used together to target a broader spectrum of insects and reduce the risk of resistance development.

4、THIAMETHOXAM

The material shall consist of a homogeneous mixture of technical thiamethoxam, com-plying with the requirements of the FAO specification 637/TC (March 2021), together with carriers and any other necessary formulants.

5、Pesticide composition containing brassinolide compound, pyraclostrobin

A technology of ester compound and pesticide composition is applied in the field of pesticide composition of thiamethoxam, brassin lactone-containing compound and pyraclostrobin to achieve the effect of reducing drug resistance, improving control effect and improving quality. Effect

Effect of 14

As a new Plant growth regulator, 14-hydroxylated brassinosteroids (14-HBR) increase biological activity by 50% than the traditional Brassicin sterols, while the relation effect of 14-HBR on rapeseed growth, yield and seed coating pesticide were not clear.

Why can brassinolide be used in various crops?

At the same time, it can be used together with other pesticides and fertilizers to improve the utilization rate. In the planting process, brassinolide is often used together with other products, which can reduce the occurrence of drug damage and enhance the efficacy at the same time.

Brassinolide

BL (Brassinolide) and BRs (Brassinosteroids) are defined as a group of plant hormones that occur at low concentrations throughout the plant kingdom and have been isolated from various species of embryophytes, including angiosperms, gymnosperms, and certain algae.

How to use brassinolides

Foliar spraying: 0.01% brassinolide can be diluted with water at the ratio of 1:20 and then evenly sprayed on the front and back of the growing leaves and flowers.

Chemistry:Thiamethoxam

A 2018 review by the European Food Safety Authority (EFSA) concluded that most uses of neonicotinoid pesticides such as Thiamethoxam represent a risk to wild bees and honeybees.

Thiamethoxam is a selective plant growth regulator primarily used to inhibit the activity of certain enzymes within plants, thereby affecting their growth and development. Brassinolide, on the other hand, is a natural plant hormone that promotes plant growth, development, and crop yield.

In agricultural production, thiamethoxam and brassinolide can be used together to enhance crop stress resistance, promote growth and development, and increase yields. Below is a detailed analysis of their combined use:

1. Mechanism of Thiamethoxam

Thiamethoxam inhibits plant growth and development by targeting key enzymes involved in cellular processes, such as protein kinases (critical for cell division) and enzymes related to protein synthesis. By binding to these enzymes and inactivating them, thiamethoxam disrupts physiological pathways that regulate plant growth.

2. Mechanism of Brassinolide

As a natural plant hormone, brassinolide modulates hormonal balance within plants. It boosts the synthesis and accumulation of gibberellins, enhancing stress resistance and growth potential. Additionally, it accelerates the degradation of auxins (e.g., indole-3-acetic acid), reducing their levels in plants. This regulation improves photosynthesis, respiration, and overall metabolic efficiency.

3. Synergistic Effects of Thiamethoxam and Brassinolide

When used together, thiamethoxam and brassinolide offer complementary benefits:

• Dual Enzyme Inhibition: Both agents suppress enzymes linked to excessive growth, ensuring balanced development.
• Hormonal Regulation: Brassinolide’s gibberellin-promoting effects counteract potential growth restrictions caused by thiamethoxam, optimizing stress resistance and development.
• Enhanced Metabolism: Combined use improves photosynthetic and respiratory efficiency, leading to higher yields.

4. Practical Applications

In crops like cotton, rice, wheat, and maize, thiamethoxam and brassinolide are applied to:

• Improve stress tolerance (e.g., disease resistance, drought adaptation).
• Stimulate robust growth and increase grain/fruit quality.
• Boost overall productivity while minimizing chemical dependency.

5. Precautions for Use

• Dosage: Calibrate dosages based on crop type, growth stage, and soil conditions to avoid growth inhibition.
• Application Method: Mix or apply separately depending on crop sensitivity. Follow product guidelines to prevent damage.
• Monitoring: Regularly assess crop health and adjust treatments as needed to optimize outcomes.

Thiamethoxam and brassinolide can be effectively combined to enhance crop performance. careful attention to dosage, application protocols, and ongoing monitoring is essential to maximize benefits while mitigating risks.
