Farming and Crop Protection

Step 1 to Success: Right Seed Selection

You only have one shot, make it right! Good quality seeds are essential to grow a strong and healthy crop. Choose what’s right for you depending on your local conditions and desired grain quality.

Right Seed Selection

There are a variety of factors to consider when selecting a rice variety:

  • Adaptability to local condition
  • High-yielding and certified seeds
  • Good grain quality
  • Resistance to insect pests and diseases
  • Maturity or growth duration
  • Lodging resistance
  • Moderate seed dormancy
  • Tolerance to adverse soil conditions
  • Tolerance to drought

There are generally two types of seeds to consider—inbreds and hybrids. According to IRRI, locally adapted varieties ensure good crop establishment and high yield with acceptable grain quality for market.

Did you know?

There are pests such as seedling maggots that can damage your rice seeds. Using the right, quality solutions can eliminate damaging insects.

Regent® will not only eliminate insect pest during seedling preparation, it will also have a residual activity even after transplanting. In addition, it will also enhance the root system, making it healthy and vigorous which is very important for establishment into the soil and uptake water and nutrient.
