objective
A tomato farmer observes lower leaves turning yellow, wilting of the whole plant, and brown discoloration of the vascular tissue in the stem. Laboratory analysis isolates a soil‑borne fungus that produces microsclerotia. Identify the disease and propose an integrated management plan that includes cultural, chemical, and genetic control measures.
Answer Options
A.
Verticillium wilt of tomato; manage by crop rotation with non‑hosts, soil solarisation or deep ploughing, apply a systemic fungicide (e.g., metalaxyl) as seed‑treatment or soil‑drench, and use Verticillium‑resistant tomato varieties.
Correct Answer
B.
Fusarium wilt of tomato; manage by crop rotation with non‑hosts, soil solarisation or deep ploughing, apply a systemic fungicide (e.g., carbendazim) as seed‑treatment or soil‑drench, and use Fusarium‑resistant tomato varieties.
C.
Bacterial wilt of tomato; manage by crop rotation with non‑hosts, soil solarisation or deep ploughing, apply a systemic fungicide (e.g., carbendazim) as seed‑treatment or soil‑drench, and use bacterial‑resistant tomato varieties.
D.
Late blight of tomato; manage by crop rotation with non‑hosts, soil solarisation or deep ploughing, apply a systemic fungicide (e.g., carbendazim) as seed‑treatment or soil‑drench, and use late‑blight‑resistant tomato varieties.
Correct Answer
B
Correct Option:
Fusarium wilt of tomato; manage by crop rotation with non‑hosts, soil solarisation or deep ploughing, apply a systemic fungicide (e.g., carbendazim) as seed‑treatment or soil‑drench, and use Fusarium‑resistant tomato varieties.
