  • Seed Health Index Calculator

    Seed Health Index

    Definition:
    Seed Health Index (SHI) is a measure of the proportion of healthy seeds in a seed sample. It reflects the overall health status of seeds by excluding infected or diseased seeds and is commonly used in seed pathology and seed quality assessment.
    Seed Health Index (%) =
    (Number of healthy seeds / Total number of seeds examined) × 100

  • Seed Transmission Rate

    Seed Transmission Rate

    Definition:
    Seed transmission rate is the percentage of seedlings that become infected as a result of pathogens carried by infected seeds. It indicates the efficiency with which a seed-borne pathogen is transmitted from seed to seedling and is used in seed pathology and epidemiological studies.
    Seed Transmission Rate (%) =
    (Number of infected seedlings / Number of infected seeds sown) × 100

  • Seed treatment dosage calculator

    Seed Treatment Dosage Calculator

    Definition:
    Seed treatment dosage refers to the quantity of chemical or biological treatment required to treat a given quantity of seed. Correct dosage ensures effective disease control, seed safety, and uniform treatment, and is critical in seed technology and crop protection practices.
    Seed Treatment Dosage =
    (Recommended dose per kg × Total seed quantity)

  • Seed treatment efficiency Calculator

    Seed Treatment Efficiency

    Definition:
    Seed treatment efficiency refers to the effectiveness of a seed treatment in reducing seed-borne infection. It is expressed as the percentage reduction in infection level after treatment compared to untreated (control) seeds and is widely used in seed pathology and seed technology studies.
    Seed Treatment Efficiency (%) =
    [(Infection in control − Infection after treatment) / Infection in control] × 100

  • Seedling Infection Rate Calculator

    Seedling Infection Rate

    Definition:
    Seedling infection rate is the percentage of seedlings that show disease symptoms after emergence. It indicates the extent of disease development at the seedling stage and is commonly used in seed pathology and plant disease assessment.
    Seedling Infection Rate (%) =
    (Number of infected seedlings / Total number of seedlings observed) × 100

  • Hot water treatment parameters Calculator

    Hot Water Treatment Parameters

    Definition:
    Hot water treatment parameters refer to the specific temperature and duration used to treat seeds with hot water in order to eliminate seed-borne pathogens without adversely affecting seed viability. Correct parameters are critical for effective disease control in seed technology.
    General guideline: Most hot water treatments are carried out between 50–55 °C for 10–30 minutes, depending on crop and pathogen.

  • Seed Survival Percentage Calculator

    Seed Survival Percentage

    Definition:
    Seed survival percentage refers to the proportion of seeds that remain viable or survive after a treatment, storage, or stress condition. It is expressed as a percentage of the total number of seeds tested and is used in seed technology and seed pathology to assess treatment safety.
    Seed Survival Percentage (%) =
    (Number of surviving seeds / Total number of seeds tested) × 100

  • Pathogen load per seed Calculator

    Pathogen Load per Seed

    Definition:
    Pathogen load per seed refers to the average quantity of pathogenic propagules (such as spores, bacterial cells, or viral particles) present on or within a single seed. It is used in seed pathology to assess the intensity of seed-borne infection.
    Pathogen Load per Seed =
    (Total pathogen units detected / Total number of seeds tested)

  • Treated vs untreated comparison

    Treated vs Untreated Comparison

    Definition:
    Treated vs untreated comparison is used to evaluate the effect of a seed treatment by comparing disease or infection levels in treated seeds against untreated (control) seeds. It helps quantify the benefit of treatment in seed pathology and crop protection.
    Reduction due to Treatment (%) =
    [(Untreated value − Treated value) / Untreated value] × 100
