as Dual should not be considered for use in pearl millet. The silage yield data

in 1994, reflected the same general trend in yield response to herbicides as the

1993 grain yield. The herbicide treatments applied to pearl millet in 1994

caused slight to moderate injury to pearl millet shortly after treatment, but the

crop completely recovered later in the growing season (data not shown). When

compared to yield data for the handweeded check, Dual, Atrazine at 2 Ibs/A,

Ramrod + 2,4-D at 2.25 + 0.45 lbs/A, and Prowl + Atrazine at 0.75 + 1.0 lb/A

reduced pearl millet silage yield (Table 4). In the 1994 no-till system, most

of the herbicide treatments resulted in significant reduction in pearl millet

silage yield, as compared to the handweeded check (Table 5).

 Control of grasses such as Texas panicum was a major concern for developing

weed control systems in pearl millet. Preliminary experiments in greenhouse and

under field conditions were directed to controlling grasses in pearl millet.

Previous experience in grain sorghum and corn indicated an early post-emergence

applications of Atrazine and/or Prowl would control seedling (1-2 leaf) Texas

panicum. Greenhouse experiments confirm that Atrazine or Atrazine + Prowl would

control seedling grasses, but could also significantly injure pearl millet. At

rates and timing normally used in field corn or grain sorghum, Atrazine in excess

of 1 lb/A to 2-3 leaf pearl millet caused moderate to severe injury, but

suppressed Texas panicum emerging or in the 1-2 leaf stage. Application of

Atrazine at 1 lb/A to 4-leaf pearl millet did not cause significant injury, but

did not control Texas panicum beyond the 1-2 leaf stage. Several greenhouse

experiments involving rates and timing of application with Atrazine in various

combinations confirmed these results (data not shown). In 1991, two field

demonstration plots treated early postemergence with Atrazine at 1 lb/A confirmed

greenhouse experiments (Table 6).

 The growth habit of pearl millet dictated that cultural aspects of weed

management needed to be evaluated. This include plant population, row spacing,

and the concept of stale seedbed preparation. Preliminary greenhouse experiments
