Harvest the edible pod or sugar pod type of peas before the pea seeds are clearly visible. The major problem in growing peas in Delaware is root rot. Root rot can be controlled by rotating the planting site and selecting a site with well-drained soil. Birds also love peas because the pea crop is one of the earliest available to feed their young. The best control against birds is netting.
Peas present few insect problems.
On occasion aphids can be found on peas. Wash or rub these off since infestation will be localized and insects will be grouped together. Diazinon or malathion can be used if the infestation is heavy. Seedcorn maggots in soil can prevent seeds from germinating. Armyworms or earworms may be found in peas during heavy worm years.
