Arrival of the often irascible Africanized honey bee in California has been anticipated, but not until the 1990s. The bee and its probable impact on the state are the subject of this article by bee researcher Norman Gary and co-authors.

A new method of calculating optimum temperatures for growth suggests some northern Central Valley areas might suitable for cotton.

This thorny pest has spread from an estimated 1.2 million acres in 1958 to 7.9 million in 1985, much of it in northern California.

A new fungicide against Rhizoctonia combined with an anti-Pythium compound performed better than the standard bean seed treatment.

Immigration reform or changes in farm labor laws would affect different crops differently.

A weed management system tested for small farms combines plastic mulch, drip irrigation, and in some cases, a preplant broad-spectrum weed killer.

Experiments with colony distribution and forager efficiency turned up some potential improvements.

When Amorbia cuneana and omnivorous looper show signs of building up, releases of an egg parasite can effectively augment natural control.

Preemergence herbicides give longer lasting control under low-volume sprinklers than drip, but the frequent wetting still causes weed problems.

It may be practical to use herbicides to reduce foxtail seed heads, the main contaminant.

When feed was abundant after milking, cows tended to eat rather than lie down, desirable behavior for feed intake and possibly mastitis reduction.
