Integrated Pest Management Options

Infected plants can be found individually or in irregular patches. These plants are often stunted and yellow (chlorotic) with dark browning or blacking of the subcrown internodes. Drought and warm temperatures favour root rot. Maintain sound soil health practices and use good 3 year crop rotation using non-host crops. Avoid soil compaction and deep seeding.
