Diseases of Field & Horticultural Crops & their Management-II

PATH 373 is an advanced crop-disease management course covering important diseases of additional field and horticultural crops, with emphasis on symptoms, causal organisms, and integrated management.

Wheat rusts are important because they are historically significant, highly destructive diseases that can spread rapidly and reduce grain yield and quality when susceptible varieties and favorable weather coincide.

Sugarcane diseases are studied in detail because they affect a major commercial crop and include fungal, bacterial, and phytoplasma-related problems with strong effects on cane yield and ratoon productivity.

They are emphasized because these diseases are common, economically serious, and excellent examples of how crop-specific symptoms and environment interact with management strategy.

These diseases are important because they occur across many crops, differ biologically, and require students to understand symptom differences, favorable conditions, and appropriate control logic.

It is essential because single-method control is often unreliable, so farmers need combinations of resistant varieties, sanitation, crop rotation, healthy planting material, monitoring, and rational pesticide use.

They compare diseases across crops because repeated disease patterns such as blights, wilts, cankers, rots, and mildews become easier to remember and diagnose when studied comparatively.

They are important because practical exposure helps students connect textbook disease names with real symptoms, field spread, and diagnostic variation across crops.
