Abstract
Blackstrap molasses was used as an additive with methyl parathion, a mixture of Strobane® (terpene polychorinates (65% chlorine)) and monocrotophos, and a mixture of Strobane, DDT, and methyl parathion in 5 field and laboratory tests against the bollworm, Heliothis zea (Boddie), and the tobacco budworm, H. virescens (F.). Addition of molasses to a toxicant produced a significant difference in control only 1 time in 8 comparisons made in 5 field tests and 1 laboratory test. Seven times out of 8 the differences among treatments were too small to be significant, although numerical differences favored molasses in each case. The 1 test where the molasses treatment was significantly better than the toxicant used alone was in a field test against a heavy infestation. The residual activity of methyl parathion was markedly extended with the addition of molasses in the laboratory test. One gallon of molasses was superior to ½ gallon per acre. The phytotoxicity of methyl parathion was reduced in 1 field test with addition of molasses.
