·         Aphids can be washed off plants with a hard stream of water. They have several natural predators that control populations including parasites (aphids appear grey or bloated), lady beetle larvae and lacewings.

·         Seedcorn maggot – Avoid heavy applications of manure or organic matter, as this can attract the flies and encourage egg laying.  

• Peas are subject to an array of root rots and wilts caused by different pathogens that are difficult to distinguish in the field and extremely difficult to control. The pathogens survive in the soil in dormant states that can persist for many years. Varieties resistant to all races of Fusarium oxysporum f. sp. pisi are available, and others with resistance to Pythium spp. and Fusarium solani f. sp. pisi are under development.
• Peas are also subject to several leaf and pod blights, of which the most important are probably aschochyta blight (caused by any of three related species) and bacterial blight ( Pseudomonas syringae pv. pisi). Both these diseases are highly transmissible by seed; all of our pea seed is grown in arid areas in which these diseases do not occur. All pea plant residues should be buried, burned, or composted at high temperatures to destroy disease organisms.
• Powdery mildew can be checked by providing good air circulation. Give plants wide spacing and eliminate weeds, especially milkweed, marshcress and yellowrocket. Choose resistant varieties.
