Abstract

In parts of the alfalfa seed producing areas in the southern San Joaquin and Sacramento valleys, toxaphene has lost some of its original toxicity to lygus bugs. Where such toxicity loss occurs, toxaphene applied early in the year generally provides satisfactory control, but when applied late in the season control of the lygus bugs is poor.
