1 Effectiveness in Controlling Tea Branch Blight

What is Tea Branch Blight?

There are many reasons why tea trees are prone to diseases, including poor growing environment, pests and diseases, viral infections, unsuitable climate, etc. Common tea tree diseases include branch blight, leaf spot, tea ripe spot, tea brown spot, leaf extraction disease, tea green leaf disease, etc.

Among these, tea branch blight is a challenging problem in Taiwan tea cultivation. It has profound impacts on tea yield and is easily transmitted. Tea branch blight is a fungal infectious disease in tea areas, where branches and leaves first fade in color, then the entire branch wilts and dries up. In severe cases, it can attack the main trunk, causing the entire plant to die.

What is the Relationship Between Tea Branch Blight and Soil Continuous Cropping Obstacles?

Soil continuous cropping obstacles refer to problems such as decreased soil fertility and pathogen accumulation when the same crop is planted continuously for a long time, leading to crop diseases or yield reduction. This occurs because when the same crop is planted continuously for a long time, the soil microbial community is disrupted, resulting in single and poor microbial composition, disrupted balance, and gradual loss of soil nutrients.

Continuous cropping obstacles mean that planting the same crop in the same place for many consecutive years increases the number of pathogens and parasites in the soil, gradually depletes soil nutrients, causing crop yield reduction or disease. Branch blight refers to diseases in tea trees during growth due to soil and environmental reasons, with common symptoms including leaf yellowing, branch withering, inability to produce new buds, etc. Therefore, there is a close relationship between continuous cropping obstacles and branch blight, and continuous cropping obstacles may exacerbate the occurrence of branch blight.

Why Can It Control Tea Branch Blight?

Agricultural Active Water is manufactured by NS BIO, which can promote the reproduction of probiotics in the soil and help restore healthy soil microbial composition. Additionally, Agricultural Active Water, through rich multi-microbial communities, can effectively inhibit pathogen growth, reduce and control pathogens, prevent accumulation of harmful substances in the soil, and reduce pesticide use.

For tea trees, Agricultural Active Water can aggregate soil, release nutrients within it, help tea trees develop better roots, thereby overcoming continuous cropping obstacles, and improve soil fertility and water retention capacity, effectively improving the soil environment.

3. Contains rich trace elements, secondary fermentation products and amino acids, etc.
4. Can be used throughout the entire growth period, compatible with current farming processes, convenient for field farm management.

What is the Recommended Usage Timing?

The usage timing during tea tree planting period is:

1. Environment construction: Tea garden management, building good microbial composition, generating good rhizosphere environment.
2. Disease improvement: If disease symptoms occur, recommend increasing usage frequency to alleviate and improve symptoms.
3. Environment maintenance: Conduct microbial composition maintenance 1-2 times per month, maintaining good soil dominant microbial groups.

3 Causes and Prevention of Tea Branch Blight

What Are the Formation Factors of Tea Branch Blight?

Symptoms of tea branch blight include: leaf yellowing, leaf surface losing luster, leaf color changing from light green to light brown, dark brown, withered leaves falling, branches turning brown. The pathogen of branch blight usually invades and infects branches through wounds, then forms spore chambers on branches and releases conidia, causing branch damage and eventually browning and drying up.

Related causes of tea branch blight formation are as follows:

1. Climate factors: High temperature, drought, strong winds make tea trees more susceptible to branch blight.
2. Soil factors: Too low or too high humus in tea tree rhizosphere, incorrect pH value make tea trees more susceptible to branch blight.
3. Fertilizer factors: Too much or too little fertilization affects tea tree growth, making tea trees more susceptible to branch blight.
4. Pest and disease factors: After tea trees are attacked by pests and diseases, they become more susceptible to branch blight.
5. Continuous cropping factors: Long-term continuous cropping in the same area, using chemical fertilizers and pesticides causing soil deterioration, poor microbial composition, increasing problems like tea branch blight.

How to Prevent Tea Branch Blight?

The main cause of tea branch blight is lack of necessary nutrients in the soil or poor environmental conditions. When tea branch blight occurs, symptoms include branch withering, wilting, leaf yellowing, etc. Therefore, to prevent tea branch blight, the prevention measures direction is as follows:

1. Soil management: Regular application of organic fertilizers can provide rich nutrients and beneficial microorganisms for tea trees, promoting healthy tea tree growth.
2. Water management: Maintaining appropriate soil moisture can prevent tea trees from water shortage.
3. Pest and disease control: Regularly inspect tea trees, if pests and diseases are found, use effective control measures early.
4. Manage tea tree leaf area: Properly prune tea trees to maintain appropriate leaf area, promoting healthy tea tree growth.
5. Appropriate plant conservation: Ensure the environmental conditions where tea trees are located are suitable, can reduce the occurrence of branch blight.

Why Can't Traditional Pesticides Completely Cure Tea Branch Blight?

Traditional spraying of fungicides, garden cleaning and irrigation management can control some spread, but many severely infected tea gardens have soil hardening and compaction, tea trees with shallow roots or weak roots unable to extend, and other soil diseases can also be seen. Long-term effects cause shortened tea tree lifespan "previously tea trees could be harvested for almost 20 years, now tree vigor weakens in 10 years, needing to be dug up and replanted in a few years." Therefore, poor soil environment will weaken tea tree nutritional organs (roots), affect immunity, shallow roots also disadvantage tea trees from deep rooting to independently absorb water, affecting tea tree self-water management, plus pesticide use increases tea tree dependence, external environment is dry, various reasons cause tea branch blight to break out severely, spreading within tea areas and fundamentally unable to be completely cured.

So the foundation for controlling tea branch blight still lies in健全 soil environment. Our customers use Agricultural Active Water,配合 enhanced biological humus fertilizer management, improving soil structure and microbial ecological environment. This improves the health of the entire tea garden to each tea tree from the constitution. Effects are not immediately visible, but with small frequent applications, giving tea trees one year, they will reward you with several more years of harvest.
