Seed Rots and Seedling Diseases of Sorghum
Seed Rots and Seedling Diseases (fungi - Rhizoctonia solani,
Fusarium sp., Pythium sp. and others): Seed rots and seedling diseases are more
prevalent when seed is planted in cool, wet soils, and especially when packing
rains seal the soil surface. Seedling emergence and growth is
slowed under such conditions, and several soil-borne fungi are able
to infect the tender seedlings. Other factors such as poor seed quality or improperly placed fertilizer
or herbicide often contribute to the problem. Continuous growth of
one crop over a period of years may favor buildup of organisms that cause
seedling disease. Use of high quality seed treated with a recommended seed protectant
is important. Precision planting to insure proper depth in a well-prepared
seedbed is very helpful.
