Weed control in irrigated peanuts was evaluated under arid conditions over an 8-year period. Weed competition during the first 8 weeks of the growing season, affected the yield in three out of eight experiments. Mechanical cultivation and herbicides alone or in combination did not control the weed population completely. The best weed control was accomplished by the combination of two herbicides, a system which allowed a complementary effect and long-term control of annual weeds.
