Answer 1

Short answer: There is no reliable curative chemical treatment for bacterial wilt and fungicides do not work. Management relies on prevention and cultural practices.

Useful measures
- Remove and destroy infected plants (do not compost) to reduce inoculum.
- Use resistant or tolerant varieties and/or graft susceptible scions onto resistant rootstocks (where available).
- Crop rotation with non‑host crops for several seasons to reduce pathogen levels.
- Proper irrigation and drainage: avoid waterlogging and wide fluctuations in soil moisture; minimize root injury.
- Sanitation: disinfect tools, stakes, and trays; use certified disease‑free seed/planting material.
- Soil solarization, hot water treatment of transplants, and avoiding movement of contaminated soil can help.
- Biological control and other treatments are experimental and have variable results.

So: select “No treatment available” (no chemical cure) and “Crop rotation” and “Proper irrigation” as correct management approaches; “Fungicides” are not effective.
