Seed Treatment

Why seed treatment? here is the answer- Seed is a basic and vital input for sustained growth in agricultural productivity and production since ninety percent of the food crops are grown from seed. The role of seed in agriculture sector
is of prime importance in developing countries like India where the population and GDP (Gross Domestic
Product) considerably depends on the agriculture sector. The seed-borne and early season diseases and insects create devastating consequences if not managed timely. Emphasis on present-day agriculture is
to produce more with lesser land, water, and manpower. The age-old environmentally friendly disease management practice like sanitation, crop rotation, mixed cropping, adjustment of date of sowing, following, summer plowing, green manuring composting, etc. to combat plant pathogens
have already lost their acceptability and are being reevaluated as a component of integrated pest management. The chemical control via soil/foliar application has its limitation such as high cost, selectivity, effect on target organisms, development of pest resistance, resurgence of pests, pollution of food and feed, health hazards, toxicity towards plants and animals, environmental pollution, etc.

What is Seed Treatment?

“Seed Treatment” is the process in which the seeds are treated before sowing to overcome heavy losses due to natural & unforeseen infections.”

Seed treatment refers to the exposure of the seeds to certain agents physical, chemical or biological which are not employed to make the seeds, pest or disease-free only but treated to provide the possibility of pest and disease control also when needed during germination and emergence of young plant and early growth of the
plant. Seed treatments have played and are still playing a pivotal role in sustainable crop production which is also evidenced by the history of mankind. Seed treatments have helped to improve the yields of many different crops by protecting pre and post-emergent insects and diseases and insurance of a uniform stand across a wide variety of soil types, cultural practices, and environmental conditions. Seed treatments provide an economical crop input that is applied directly to the seed using highly effective technology.

Moreover, other crop protection techniques are now being replaced with seed treatments by their residual systemic efficacy. From time to time different techniques have been proposed for applying and more
advanced techniques are required which give more control of plant diseases by affecting seed health least.

Objectives of seed treatment:

●Convenience in sowing.
●Disease control includes seed born, soil born & air born diseases.
●Insect control like white ants and other ants, termites.
●Quicker germination.
●Better yield.
●Protection against insects.
● Increasing nitrogen fixation.

Seed treatment has some advantages over other pests control or crop enhancement measures such as:
• More alternatives available to chemicals in an effective manner.
• Protection of seed during storage and after planting in soil.
• Reduction in initial inoculum.
• Minimize the environmental side effects viz. reduce risk to non-target organism, no problem of drift and
reduction in land surface exposed to active ingredients with maximum efficacy reduce the rate of application per hectare, thus decrease the cost of disease control per ha while achieving exceptional control of seed-borne, soil-borne and foliar diseases.
• Increase seed vigor which is the key to successful field emergence and establishment.
• Even and uniform application of the chemical.
• A Combination of treatment can be applied more precisely.
• Breaking of seed dormancy and improve emergence and plant stand.
