Alfalfa weevils have been reported damaging alfalfa in north central Kansas and western Nebraska. As temperatures warm up, expect to see alfalfa weevil larvae in southern Nebraska and slightly later, in northern Nebraska. Even with the pressure of planting row crops, it is essential that producers growing high quality alfalfa hay make time to monitor fields for weevils now and over the next few weeks. See the article for a table of treatment thresholds for various alfalfa prices.

When it comes to buying corn seed, one way to save money can be to ensure that you don't invest in GMO insect protection traits that you do not need for your particular farm or field.

Grain-type field peas are a cool season grain crop grown as an alternative for no-till summer fallow in a semiarid cereal-based cropping systems such as wheat-corn-fallow and/or wheat-fallow. They are typically planted in mid-March and harvested late-July. This article reports on research conducted on seeding practices and offers recommendations for producers on the economically optimal seeding rate, seeding depth, and inoculant to grow field peas in western Nebraska.
While entomologists in the Eastern Corn Belt this month reported reduced efficacy of the Cry1f Bt protein against western bean cutworm in corn, Nebraska growers have been facing this for several years. While Cry1F products will still help control other pests, growers are advised to scout for WBC and determine whether treatment is necessary.
