Alfalfa is commonly affected by several pests, including aphids, which can weaken plants by sucking sap; spider mites, which create fine webs and lead to discoloration; and alfalfa weevils, which can cause significant damage by feeding on leaves. Additionally, root-feeding nematodes and various beetles, such as the root-crown borer, can also threaten alfalfa health. Effective pest management is essential to maintain crop yield and quality.
