1. Basic Attributes

• Product Name: Silwet 819
• Chemical Category: Novel Patented Compound Synergist
• Appearance and Form: Typically a colorless to pale yellow transparent liquid with good fluidity

2. Core Performance

2.1 High Safety While Ensuring Efficacy

• As a novel patented compound, Silwet 819 ensures pesticide efficacy while significantly improving safety. In the citrus production area of Guangxi, when mixed with azoxystrobin and copper-based pesticides at a dilution ratio of 250:1, it shows no phytotoxicity to young citrus fruits. This solves the problem of potential fruit damage caused by traditional synergists or pesticide mixtures during the young fruit stage, providing a safe guarantee for pesticide application in this critical period.

2.2 Formulation Compatibility

• It has good miscibility with common pesticides such as azoxystrobin and copper-based formulations. There is no risk of flocculation or delamination when mixed, allowing for direct tank mixing, which simplifies the application process.

3. Application Scenarios and Usage Methods

• Disease and Pest Control During Young Fruit Stage of Citrus: In Guangxi and other citrus-growing regions, during the young fruit stage, mix Silwet 819 with azoxystrobin, copper-based pesticides, etc., at a dilution ratio of 250:1 and spray. It can effectively control diseases such as citrus scab and anthracnose without harming young fruits.
• Pesticide Application During Young Fruit Stage of Other Fruit Trees: It can be extended to apple, pear, and other fruit trees for pest control during their young fruit stage, especially suitable for periods when young fruits are sensitive to phytotoxicity. The specific concentration can be adjusted according to fruit tree varieties, pesticide types, and application environments.

4. Competitive Advantages

• Safety Breakthrough: Compared with traditional synergists, the safety of Silwet 819 during the young fruit stage is its core advantage. It allows fruit growers to apply pesticides with confidence during this period, avoiding economic losses due to phytotoxicity, while ensuring efficacy, achieving the dual goal of "safe application + efficient control".
• Strong Targeting: It is specifically developed to address the pain point of phytotoxicity during the young fruit stage of fruit trees, with clear application scenarios, and has strong market targeting and competitiveness in citrus and other fruit-growing areas.

5. Storage and Packaging

• Storage Conditions: Store in a sealed container in a cool and dry place, away from direct sunlight. The recommended storage temperature is 5-35℃, and the shelf life is usually 2-3 years.
• Packaging Forms: Common packages are 5L and 20L plastic barrels. Customized packaging (such as small-scale experimental packages) can also be provided according to requirements.
