Solution Biological method for seed treatment
Country India
Last update: 08/10/2006
Summary If the spectacular success of the green revolution was to be attributed to a single factor, it would invariably be the seeds of the high yielding varieties (HYVs). But most of these seeds are highly susceptible to diseases and pests. Some times they also act as carrier of disease pathogens. Seed borne diseases are commonly observed in cereals, pulses and vegetables. To control the seed borne diseases farmers use many chemicals for seed treatment which are poisonous or toxic to human being. In this context, biological method of seed treatment can play a vital role by controlling the disease in one hand and minimize the health hazards on the other. In this GP some biological methods of seed treatment are mentioned.

Challenge/Issue Seeds of many High Yielding Varieties (HYVs) are highly disease susceptible. Some times they also act as carrier of disease pathogens. At the time of seed germination the resting mycelium or spore lodged inside the seed coat become active and under suitable condition infecting the seedlings.

Many chemicals used for the treatment of seeds are poisonous or toxic to human being and results in health hazards.
Method 1.The recent trend is to use bio-control agents like Trichoderma viridae @ 4 g / kg of seed or Pseudomonas flourescens @ 4-5 g / kg of seed. These can be applied to a wide range of seeds.

2.Corn seed can be treated with Clavibacter xylii against corn borer.

3.Seed treatment with Rhizobium sp. to treat leguminous seed for nitrogen fixation.

4.Bio-priming (coating seed with biological materials) is also effective to control seed borne pathogens. Bio-priming materials are leaf powder of Neem (Azadiracta indica), Notchi, Pongamia, Rhizobium, VAM etc.
Lessons learned 1.Seed treatment through biological method is safe to human being.

2.The methods are easy to adopt and economically viable.

3.The plants raised are less susceptible to pathogen.

4.The produces will be superior in quality.
