Core Product Features
- Superior Wetting and Penetration: Effectively reduces the surface tension of spray liquids (to below 20.5 mN/m at 0.1% concentration), minimizing the contact angle between the liquid and leaf surfaces. It penetrates leaf stomata quickly, enhancing the absorption efficiency of active ingredients.
- Enhanced Rain Resistance: Promotes rapid absorption of pesticides by plants, reducing loss caused by rainfall after spraying and ensuring the effectiveness of agricultural inputs.
- Synergy and Dosage Reduction: Increases spray coverage significantly, allowing the reduction of water usage to 1/2-2/3 of the conventional amount and pesticide dosage to 70%-80% of the standard dose, achieving cost savings and environmental protection.
- Good Compatibility: Compatible with most agricultural inputs such as insecticides, fungicides, herbicides, foliar fertilizers, and plant growth regulators, without affecting product stability.
Application Scope & Usage Guidelines
Application Fields
Suitable for mixing with insecticides, fungicides, herbicides, foliar fertilizers, plant growth regulators, and other agricultural products, applicable to various field crops, cash crops, and horticultural plants.
Recommended Dosage (by Product Type)
| Application Type |
Dosage Range |
| Insecticides |
0.025% ~ 0.1% |
| Fungicides |
0.015% ~ 0.05% |
| Herbicides |
0.025% ~ 0.15% |
| Foliar Fertilizers & Trace Elements |
0.015% ~ 0.1% |
| Plant Growth Regulators |
0.025% ~ 0.05% |
Usage Methods
- Barrel Mixing: Add 5g of RH-208 to 20kg of spray liquid (4000x dilution), mix well before use. For systemic pesticides, increase the dosage appropriately to enhance absorption.
- Pesticide Formulation Addition: Add 0.5%-8% of RH-208 to pesticide stock solutions. Adjust the pH of the formulation to 6.5-7.5 with a slow-release agent to prevent hydrolysis (organic silicon surfactants are susceptible to hydrolysis under extreme pH conditions).
- Operation Steps: First dissolve the pesticide, add 80% of the required water and mix evenly, then add RH-208, and finally make up to 100% water volume and mix thoroughly. Use a small-diameter nozzle and appropriate spray speed for optimal results.
Precautions
- The optimal pH range for the mixed solution is 5-8, and it should be used within 24 hours after preparation.
- Store in a dry, cool, and well-ventilated place, avoiding direct sunlight and high temperatures.
- Avoid mixing with strong acids, strong alkalis, or oxidizing agents to prevent product degradation.
- Follow recommended dosages; excessive use may cause phytotoxicity to sensitive crops.
