Usually, camelina does not need any field interventions. However, perennial weeds may be difficult to control. Some specialized oilseed herbicides can be used on it. Also, camelina is highly resistant to black leg and "Alternaria brassicae", but it can be susceptible to sclerotinia stem rot. No insect has been found to cause economic damage to camelina. Camelina needs little water or nitrogen to flourish; it can be grown on marginal agricultural lands. Fertilization requirements depend on soils, but are generally low. It may be used as a rotation crop for wheat and other cereals, to increase the health of the soil. Camelina can also show some allelopathic traits, and it can be grown in mixed crop with cereals or legumes.
