Tomato Bacterial Wilt : Burkholderia solanacearum
Symptom:
-
This is one of the most serious diseases of the tomato crop. Relatively high soil moisture and soil temperature favour disease development.
-
Characteristic symptoms of bacterial wilt are rapid and complete wilting of normally grown up plants.
-
Lower leaves may drop before wilting. The pathogen is mostly confined to the vascular region; in advantage cases, it may invade the cortex and pith and cause yellow-brown discolouration of tissues.
-
Infected plant parts when cut and immersed in clear water, a white streak of bacterial ooze is seen coming out from cut ends.
-
The spreads through wounds, soil and implements.
-
Avoid damage to seedling while transplanting
-
Apply bleaching powder @ 10kg/ha and in rate.
Management:
-
Crop rotations, viz., cowpea-maize-cabbage, okra-cowpea-maize, maize- cowpea-maize and finger millet-egg plant are reported effective in reducing bacterial wilt of tomato.
