OKLAHOMA ALFALFA PRODUCTION CALENDAR

Spotted Alfalfa Aphid

Fields (especially new fall plantings) should be checked periodically during winter for aphid infestations; spray if populations reach 10 aphids/plant in need seedling stands or 30 aphids/crown in established stands. Chances of serious damage are greatest with mild temperatures and little rainfall.
