Abstract:

The compound, 4',5-dichloro-3- (4-chlorophenyl) salicylanilide. was about 3 times more active at the LD₉₀ level and 1.5 times at the LD₅₀ level than toxaphene-DDT (2+1) against 4-day old larvae of Heliothis zea (Boddie) caged on cotton in the field. The relationship between the 2 treatments in the field differed from that in the greenhouse; previous work in the greenhouse showed the "salicylanilide" to be about 35 and 5.7 times more active than the toxaphene-DDT mixture al the LD₉₀ and LD₅₀ levels, respectively. The difference is attributed to a greater effect of solar radiation on the salicylanilide in the field.
