Bakteria ringa putro ( Clavibacter michiganensis subsp. sepedonicus)
#000017
Patogeno. The ring rot bacterium is extremely infectious. It overwinters mainly in seed tubers, but can survive for up to 2 years as dried slime on cutting knives, storage bins, planting and harvesting equipment, burlap bags, paper and plastic. The bacterium is not killed by freezing.
#000018
Evoluo de la malsano. Ring rot spreads primarily from infected seed pieces to healthy tubers during seed cutting and planting. Contaminated seed-cutter knives and pick planters are excellent disseminators of bacterial ring rot because fresh wounds provide a means of entry for the bacteria into the tuber. Ring rot may be spread in the field by direct contact between diseased and healthy plants. The bacteria may also be carried by farm equip- ment or by insects such as the Colorado potato beetle, the potato flea beetle or the green peach aphid.
#000019
Simptomoj. One of the characteristics of this disease is that the expression of foliar symptoms and the type of symptoms expressed vary depending on the variety. In In hot, dry seasons, ring rot develops rapidly. The first symptoms in the field usually appear on the lower leaves about mid-season.
#000020
Zero tolerance control measures are in place against this disease. The seed potato regula- tions in Canada indicate that upon finding bacterial ring rot, all lots under cultivation by the grower are rejected for certification.
#000021
The yellowing of interveinal areas and curling and browning of leaf edges are distinct symptoms of ring rot. Eventually, necrosis kills the leaflets.
#000022
Lower leaves usually wilt first. Interveinal areas turn yellowish.
#000023
Russet Burbank may develop the dwarf rosette symptom early in the season.
#000024
Interveinal yellowing on lower and upper leaves.
#000025
Infected tubers usually develop star-shaped cracks in the skin.
#000026
Severe tuber cracking caused by ring rot.
#000027
A creamy, yellow-brown, cheesy, odourless rot develops in the vascular ring.
#000028
Corky tissue surrounds hollows in the vascular ring. When secondary bacteria enter, a foul- smelling rot may occur, and infected tubers may be completely destroyed.
#000029
Typical ring rot symptoms on tubers.
