Seed Health Test Performed in GGAS HI-Tech Lab

The health of seeds refers primarily to the presence or absence of disease-causing organisms

such as Fungi, Viruses, bacteria and funjal pests etc. According to ISTA, the main

objective of a seed health test is to determine the health status of a seed sample.

PROTOCOL:

• To conduct a seed health test according to ISTA, a representative seed sample of the required size is obtained (depending upon the crop).
• Seeds are surface sterilized with a disinfectant followed by thorough then rinsing with sterile water.
• Seeds are then adjusted on a suitable medium (filter paper) and placed in a growth chamber, using conditions that support the growth of potential pathogens.
• The incubated seeds are regularly observed for fungal or bacterial growth.
• Pathogens are Identified by an experienced pathologist and recorded using appropriate methods and references.

BENEFITS:

• Seed health testing performed at GGAS-HITECH LAB according to ISTA guidelines can help farmers detect and avoid seeds contaminated with pathogens, reducing crop diseases and improving yield and quality.

• It ensures better plant health and lowers the risk of widespread infections, leading to more reliable and productive harvests.

• Seed health testing ensures seeds meet international phytosanitary standards, enhancing market acceptance and compliance.

• It helps in providing evidence of seed quality, reducing the risk of disputes, and building buyer confidence by demonstrating that seeds are free from harmful pathogens.
