Economic thresholds generally do not exist for plant pathogens and nematodes in Idaho field and row crops.  The following table instead lists pesticide application timing recommendations for disease and nematode management.

Peas

Pathogen		Pesticide	Timing
	Downy mildew (Peronospora viciae)	Ridomil Gold EC fungicide may be banded or surface applied at 0.5 to 1 pints/A. Band rate determinants include band width and row spacing: see label	Applying Ridomil Gold EC fungicide at planting for damping-off gives some control of early infection.
