Baker & Baker's (Bak-O-Spread) Non-ionic silicone surfactants are highly effective in agricultural applications due to their ability to enhance the performance of agrochemical sprays. These surfactants are widely used as adjuvants to improve the spread, penetration, and uptake of pesticides, herbicides, fungicides, and foliar fertilizers.

Key Benefits of Non-Ionic Silicone Surfactants

1. Improved Spray Coverage

   • Silicone surfactants reduce the surface tension of water, allowing the spray to spread more uniformly on plant surfaces, including waxy or hairy leaves.

2. Enhanced Penetration

   • They facilitate better penetration of agrochemicals into plant tissues, making treatments more effective, especially for systemic products.

3. Rainfastness

   • Helps agrochemicals adhere to the plant surface, reducing wash-off during rain and increasing the longevity of treatments.

4. Reduced Spray Drift

   • Minimizes the drift of spray droplets, ensuring more targeted application and reduced wastage.

5. Better Efficacy in Low-Volume Sprays

   • Silicone surfactants enable ultra-low-volume (ULV) spraying, reducing water usage without compromising efficacy.

6. Cost Efficiency

   • Improves the performance of agrochemicals, reducing the need for repeated applications and saving on input costs.

Applications in Agriculture

1. Pesticide Application:

   • Ensures better contact and efficacy against pests by improving spray adhesion.

2. Herbicides:

   • Enhances the performance of herbicides by increasing their absorption into weed foliage, even in tough conditions.

3. Fungicides:

   • Provides better spread and retention on leaves to improve the control of fungal diseases.

4. Foliar Fertilizers:

   • Increases the nutrient absorption through plant leaves, making fertilizers more effective.

5. Plant Growth Regulators (PGRs):

   • Enhances the uptake and action of growth regulators, ensuring uniform growth and development.

How to Use Non-Ionic Silicone Surfactants

1. Dosage:

   • Typically used at very low rates (0.025%–0.1% of spray solution). Always follow manufacturer recommendations for specific crops and applications.

2. Mixing Instructions:

   • Add the surfactant to the spray tank after the agrochemical has been mixed. Stir well to ensure proper blending.

3. Timing of Application:

   • Apply during the cooler parts of the day (early morning or late afternoon) to prevent rapid evaporation and ensure maximum absorption.

Precautions

1. Over-application may cause phytotoxicity (plant damage). Use the recommended dosage.
2. Not all silicone surfactants are compatible with every agrochemical; check for compatibility before use.
3. Avoid applying in extreme weather conditions, such as high heat or strong winds.
