How to Grow Quinoa: Pests and Diseases

Quinoa seeds are coated with a substance called “saponin” which is quite bitter and generally prevents birds and other pests from messing with the grains.

The leaves, however, can be vulnerable to damage from insects such as aphids and flea beetles. Once the plant is mature enough, it can withstand damage from these small insects without problems, but while they are young, they can pose a problem.

Some caterpillars and leafminers can also be attracted, although on a smaller scale, so it will usually be enough to remove them as you see them. Pests are not a big problem when growing quinoa.
