Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a composition for preventing seedling damping-off.
Background
The rhizoctonia rot is also called as 'dead seedling', is mainly caused by the infection of rhizoctonia solani, has a wide host range, and causes the reduction of yield of crops and great harm due to the rhizoctonia solani which often occurs in rice and corn.
The rice damping-off is one of the main diseases in the seedling stage. The rice is most likely to have damping-off in 1-leaf 1-heart to 2-leaf 1-heart stages. Damping-off often occurs in spring and greenhouse seedling raising periods. The seedlings of the rice are raised in a dry way, although the seedlings are not easy to rot, the seedling blight is most easy to occur, and the death rate of the seedlings is more than 50% in the case of heavy seedlings. When rice withers immediately, stem withers and rice leaves roll. The seedling stage is easy to have seed rot and bud rot. After the rice suffers from the diseases, stem parts of the rice wither, plants are dwarfed and turn yellow, and few or no new roots exist, when the diseases happen slightly, seedbed seedlings turn yellow, and when the diseases happen seriously, seedlings become withered in pieces.
The seedling stage of the corn seedling blight can occur from seeding to the seedling emergence stage. The rhizoctonia is mainly characterized in that sclerotium and mycelium live through the winter in soil or disease residues. Infection begins when the disease occurs. The infection optimum period is 0-10 days of the seedling age.
