Abstract and summary

Effects of 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,3,6-trichlorobenzoic acid (2,3,6-TBA) on plant numbers and on the reproductive bulbs were studied by counting plants and digging and examining the bulbs in soil cores.

Foliar application of both herbicides resulted in necrosis, reduction in size, growth abnormalities (hardshell bulbs only), changes in the makeup of bulb population, and eventually a large decline in bulb numbers. Soft offset bulbs were damaged less than central bulbs by both herbicides. Soft offset bulbs increased in proportion to total bulb population following 2,3,6-TBA treatment. Both herbicides caused abnormal growth of developing hardshell bulbs and reduced viability. At the 2-lb rate, 2,3,6-TBA reduced hardshell bulb production more than 2,4-D; at 4 lb/A, 2,3,6-TBA prevented hardshell bulb production. Dormant hardshell bulbs of previous seasons' production were not affected by either herbicide. Plant populations declined more rapidly and to a lower level than bulb populations under adverse conditions of environment and herbicide treatments. The slower decline in bulb numbers resulted from dormancy in the hardshell bulbs.
