PROTECTING AGAINST ALFALFA PESTS AND DISEASES

Knowing the prevalent pests, climate and common diseases in your area can help you select the appropriate variety. In the Pacific Northwest and the western United States, nematode activity after cutting reduces yields. In these areas, it is beneficial to protect crops by planting varieties with high resistance to stem nematode, such as these NEXGROW alfalfa varieties:

PESTS IN THE EASTERN USA

In the eastern half of the United States, alfalfa pests, especially the highly destructive potato leafhopper, can limit forage yield and quality in the seeding year and subsequent years as well. Growers in these areas should take advantage of the latest generation of alfalfa varieties which provide potato leafhopper resistance. Varieties like 6480H possess excellent potato leafhopper resistance, along with outstanding winterhardiness.

PESTS IN WET REGIONS

If heavy, wet or saturated soils are present, consider selecting NEXGROW varieties with resistance to Race 2 Aphanomyces Root Rot, a disease that causes damping-off, stunting and chlorosis of alfalfa plants. In years where the disease is prevalent, it can cause poor stand establishment and even failed stands. Selecting varieties that have excellent disease packages with a high resistance rating to Race 2 Aphanomyces Root Rot provides growers with the best chance at establishing successful stands. For high resistance to Race 2 Aphanomyces Root Rot, consider 6472A from the NEXGROW alfalfa line of products.

Even though these pests can pose a challenge year-round, the effects insects and disease have in the first 90 days are most detrimental. Therefore, identify the pests and associated agronomic concerns that may harm your alfalfa crop and choose seed bred with top-line genetics for resistance against the anticipated pests.
