Low-dose pest control Seed dressing of Seed with Fungicide and Insecticide

Pest control for optimum yields

The "Seed Dressing with Fungicide and Insecticide" technology consist to the application of chemical control agents to common bean seeds to combat fungal diseases like anthracnose and pests such as stem maggots that cause significant yield losses in Africa. It offers various seed dressing products, such as Syngenta’s APRON STAR®, which combines fungicides and insecticides to effectively control diseases and pests, leading to robust root development, uniform growth, and higher yields, especially in tropical regions with favorable conditions for fungal pathogens. This method utilizes a cost-effective and environmentally friendly approach, offering enhanced protection and increased productivity for common bean crops. This adaptable and accessible technique doesn’t require specialized equipment and is easily implementable at both farms and factories, offering a widely adoptable solution to protect common bean crops against prevalent diseases and pests in various agricultural regions.


This technology is TAAT1 validated.

  • Pervasive Yield Losses: African common beans are significantly affected by fungal diseases and insect pests like anthracnose, root rots, and stem maggots, leading to substantial yield losses.
  • Risk to Profitability: Infestations pose a significant risk to the profitability of improved crop varieties and the investments made by farmers in fertilizers.
  • Endangering Planting Material: Diseases and pests harbored by seeds endanger the integrity of planting material stocks, threatening the viability of future crops and risking widespread agricultural setbacks.

  • Threat of Crop Failure: Soil-borne diseases and insect pests pose a severe risk to common bean crops, leading to sparse plant density and even complete crop failure, exacerbating food insecurity and economic instability.


  • Prevention of Losses and Enhanced Production: Dressing common bean seeds with chemical control agents offers a cheap and environmentally friendly technology to prevent losses and enhance production.
  • Improved Seedling Emergence: The seed treatment approach results in better seedling emergence, strengthening the resistance of crop stands throughout the growing season.
  • Uniform Application of Control Agents: Seed dressing achieves a very high degree and efficiency of crop protection by guaranteeing uniform application of control agents, minimizing undesired effects on non-target organisms in soils and spillage of chemicals into water bodies.
  • Widely Adoptable Solution: The advantage of seed dressing lies in its simplicity and adaptability, as it doesn’t require specialized equipment and can be easily performed at farms and factories, making it a solution that can be widely adopted across different agricultural regions.

Key points to design your business plan

Using this technology tackles fungal diseases like anthracnose and pests such as stem maggots that cause significant  yield losses in common beans, assuring a cost-effective solution to prevent  propagation and contamination issues in common beans varieties. 

For the cost structure, consider that:

  • Chemicals cost US $0.5 to $1 for treating one or two kilograms of seed.

  • Manual application equipment is less than $50.

  • Rotary drums: Small unit $500, large unit $2,000.


Training is important because treating seed requires knowledge and skills to be performed properly and safely.

As key partners you need agro dealers.

  1. Weighing of Bean Seeds: Weigh the bean seeds to ascertain the required chemical dosage.
  2. Preparation of Chemical Formulas: Liquid formulas can be directly coated or diluted for use. Dry formulas, containing adhesives, are added directly to seeds.
  3. Manual Seed Dressing: For smaller seed volumes, use common receptacles or manually treat seeds in plastic buckets or basins. Seeds can be sprayed with the solution on a polythene sheet.
  4. Mechanical Seed Dressing: For larger seed volumes, utilize mixers, hoppers, or rotary drums powered by hand or motor.
  5. Planting and Application: Following seed treatment, plant the common beans using recommended land preparation, spacing, and fertilizers in specific growing areas.
