3. Introduction
SEED - Most efficient Input in Agriculture
Infected Seed (SB pathogens)
Primary source of inoculum
Excellent carrier for dissemination of phytopathogens
Victim & vehicle – Extensive & complex SB pathogens
Seeds are foundation to crop production
whereas
SEED HEALTH is related to food
production
73. Management strategies……
1.Selection of disease free healthy seed materials
2. Seed certification
3. Plant Quarantine
Seed Treatment Methods
1.Physical methods
Hot water treatment (Aschochyta),
Hot air treatment, Solar heat treatment etc.
2.Chemical seed treatment – Thiram, Mancozeb,
Carbendazim, Carboxin etc.
3. Biological seed treatment – BCA
Trichoderma viride , P. fluorescens
4. Biotechnological
Genetic transfer of Phenolic genes/ cell wall
74. You may not see a
positive effect every year.
However, when the proper
conditions occur for disease
development, seed treatment
will help your crop with
improved emergence & stand
establishment resulting in an
increase in yield
