The end is near for chlorpyrifos (Lorsban) applications in many California crops, now on a faster timetable than previously anticipated.

This is a major issue for alfalfa, since it is one of the most popular wide-spectrum insecticides for management of key alfalfa pests. These include the alfalfa weevil, Hypera postica, which chews on the foliage (Figure 1, Figure 2) and the aphid complex (several...

A question came to me from a crop consultant. His alfalfa grower asked him how he could increase crude protein (CP) in his alfalfa. The buyer of the alfalfa, for the most part, is happy with the hay. For example, the buyer is happy with the total digestible nutrients (TDN), but he would like to see a little higher CP. The consultant said that the grower is generally on a 28-day cutting cycle and is generally cutting the hay pre-bloom. He wondered if nitrogen (N) fertilizer would help to improve CP.
The best way to improve CP is to: 1) cut early, 2) choose a more dormant variety (but give up yield), and 3) manage the harvest to retain the leaf fraction. Since this grower is already cutting pre-bloom, and since...
