Trichloroisocyanuric acid (TCCA) granule for seed treatment

Powerful Disinfection Properties

TCCA is renowned for its potent disinfection properties, making it an ideal candidate for seed treatment. As a chlorine-based compound, TCCA efficiently eliminates bacteria, fungi, viruses, and other harmful microorganisms present on the seed surface. By eradicating these pathogens, TCCA helps prevent diseases that could otherwise hamper seed germination and early plant growth.

When seeds are exposed to TCCA during the treatment process, the active chlorine is released gradually. This controlled release ensures that the seeds receive sustained protection against harmful pathogens during critical stages of development, such as germination and early growth. By creating a protective barrier, TCCA acts as a powerful shield, preventing disease-causing agents from gaining access to the vulnerable seedlings.

Enhanced Seed Germination

Enhanced seed germination is a significant benefit of using TCCA granules for seed treatment. The presence of pathogens on seed surfaces can hinder germination and early plant growth, leading to reduced crop yields and weaker plants. However, when seeds are treated with TCCA, the potent disinfectant properties of the compound come into play.

TCCA efficiently eliminates bacteria, fungi, viruses, and other harmful microorganisms that may coat the seeds. By eradicating these pathogens, TCCA creates a clean and disease-free environment for germination to take place. With the absence of hindering pathogens, seeds can germinate more efficiently, leading to quicker and more uniform sprouting.

In areas with challenging environmental conditions, such as high humidity or poor soil quality, seed germination can be particularly vulnerable. TCCA's role in eliminating pathogens is crucial in such conditions, as it helps protect the seeds from potential infections that might thrive in unfavorable environments.

In regions where soil-borne diseases are prevalent, using TCCA granules for seed treatment becomes even more critical. Soil-borne pathogens can attack young seedlings as they emerge from the soil, leading to damping-off and other diseases that can devastate entire crops. By treating seeds with TCCA, farmers can significantly reduce the risk of such diseases and establish a healthy and robust crop stand.

The enhanced seed germination and healthier seedlings that result from TCCA treatment have a positive domino effect on crop development. Robust seedlings are better equipped to withstand environmental stresses, such as drought, extreme temperatures, and pest attacks. This resilience translates into stronger and more productive plants, ultimately leading to improved crop yields.

Disease Prevention

Disease prevention is a crucial aspect of modern agriculture, and TCCA granules play a pivotal role in this proactive approach. By incorporating TCCA into seed treatment practices, farmers establish a protective barrier on the seed surface, effectively shielding the seeds from potential pathogens present in the soil or the surrounding environment.

When seeds are sown in the field, they are vulnerable to various soil-borne pathogens that can lead to seedling diseases, damping-off, and root rot. These diseases can severely impact crop establishment and early growth, resulting in reduced yields and financial losses for farmers. However, by using TCCA granules, farmers can fortify their seeds against such threats.

The active chlorine released by TCCA upon contact with moisture forms a protective layer on the seed surface. This layer acts as a shield, deterring pathogens from infecting the seeds and subsequent seedlings. By hindering the entry and development of harmful microorganisms, TCCA ensures that the seedlings emerge healthy and vigorous, ready to withstand environmental challenges.

By taking a proactive approach to disease prevention with TCCA, farmers can reduce the reliance on chemical interventions during the growing season. Traditional pest and disease management practices often involve the use of chemical pesticides, which may have detrimental effects on the environment and non-target organisms. However, by preventing diseases right from the beginning, farmers can minimize the need for such interventions and promote eco-friendly and sustainable farming practices.

Ease of Application

TCCA granules are user-friendly and easy to apply. The granules are typically formulated to adhere well to the seed surface, ensuring even distribution of the active ingredient. Farmers can use a variety of seed treatment equipment to apply the granules efficiently, optimizing the seed treatment process and reducing waste.


TCCA granules can be used for treating various types of seeds, including those of cereal crops, vegetables, fruits, and legumes. Its versatility and broad-spectrum efficacy make it a valuable tool for different farming systems and crop types. Whether for large-scale commercial agriculture or small-scale family farms, TCCA granules offer a practical solution for seed treatment needs.

Long-lasting Protection

TCCA granules provide long-lasting protection for seeds during storage and germination. The slow-release nature of the active ingredient ensures that the seed remains protected throughout critical early stages of growth, when it is most vulnerable to diseases and pests.

Ratio of Trichloroisocyanuric acid (TCCA) granules in seed treatment

In seed treatment, the ratio of Trichloroisocyanuric acid (TCCA) granules is usually dependent on the type of seed and the treatment needs of the seed. Generally speaking, the ratio of TCCA particles can refer to the following steps.

Determine the number of seeds

First, determine the number of seeds you want to process. This can be determined by your planting plan and the amount of seeds purchased.

Determining the required TCCA level

Determine the required TCCA level based on the type of seed you are treating and your treatment needs. This is usually expressed as a percentage, such as 1% or 0.5% TCCA content.

Calculate the weight of the TCCA granules

Based on the desired TCCA content and the number of seeds, calculate the total weight of the TCCA pellets required. For example, if you have 100 kg of seeds and require 1% TCCA content, then the required weight of TCCA pellets is 100 kg x 1% = 1 kg.

Adjust the ratio of TCCA granules

According to the packaging specifications of TCCA granules, convert the required weight of TCCA granules into the packaging quantity. According to the actual packaging specifications, you may need to adjust the ratio appropriately.

Uniform mixing

Mix the calculated TCCA particles evenly according to the ratio to ensure that each seed can be evenly covered with TCCA particles.

Note that specific ratios may vary for different seed types and planting needs. For best results and safety, it is recommended to follow the directions for use and recommended proportioning provided by the product manufacturer. When working with TCCA particles, it is important to wear appropriate protective equipment and operate in a well-ventilated environment to avoid inhalation or exposure to particles.


Trichloroisocyanuric acid (TCCA) granules are a game-changer in the world of seed treatment. With their potent disinfection properties, ease of application, and versatility, TCCA granules effectively safeguard seeds against pathogens and promote healthy plant growth. By incorporating TCCA granules into their seed treatment practices, farmers can take a proactive approach to disease prevention and enhance crop productivity. As agriculture continues to evolve, the use of TCCA granules represents a step towards sustainable and efficient farming practices, ensuring a bountiful harvest and contributing to global food security.
