“…The symptoms described by Way (1962Way ( , 1964 for full-grown plants arc very similar to those we recorded, although his rates of application cannot be compared with ours. Way states (1964) that epinastic responses induced by 2,3,6-TBA were less marked than those induced by other compounds.…”

“…A useful summary of minimum recorded doses of 2,4-D causing crop damage has been made by Elliott & Wilson (1983), largely for herbicides in the liquid phase. This summary included data of Hemphill & Montgomery (1981) and Way (1964). Lettuce was rated the most sensitive, followed by tomato and cabbage.…”

Six species of crop plants (tomato, lettuce, clover, cabbage, sunflower and field bean) were exposed to concentrations of 2,4-D butyl in the range 3 -50 ng/litre, for 3.5 h, using an air-flow system. Symptoms of phytotoxicity were recorded during the following 4 wk, after which the plants were harvested. Sunflower and field bean were found to be most sensitive, with tomato, lettuce and cabbage less affected and clover least sensitive, on the basis of weight. Small tomato plants were more sensitive than ones approximately twice the weight. A 50% reduction in dry weight was caused by a 3.5 h exposure to less than 3 ng/litre 2,4-D butyl for sunflower, compared with over 50 ng/litre for clover. The ranking of sensitivities did not agree with reports based on liquid doses of 2,4-D, especially for field bean, which was found to be more sensitive than previously thought. 0 1987 Association of Applied Biologists

Blackcurrants, treated with 0.1 kg of 2,4,5‐T ha−1 (as esters of mixed C4–C6 alcohols; ‘Tormona 80’), contained 0.1 mg of 2,4,5‐T residues kg−1 in the berries at ripeness 29 days after treatment. Total residues in the berries were not reduced during growth and ripening, although the residue concentrations declined in the same period due to growth dilution. In spinach leaves from old plants, treated with 0.1 kg ha−1, 0.05 mg of 2,4,5‐T kg−1 was found 14 days after treatment. Fodder peas showed no residues (< 0.002 mg kg−1) at harvest 62 days after treatment with 2,4,5‐T esters. After application of 0.1 kg ha−1 on potato plants, the disappearance of 2,4,5‐T was rapid during the first month, but residues were translocated into the tubers and reached a constant level of 0.02 mg kg−1 after 1 month until harvest at 108 days after treatment. In all crops, visible effects were observed after treatment with 0.1 kg ha−1. After the application at 0.01 kg ha−1, phytotoxic effects were observed only in blackcurrants, but negligible residues were found in all the test crops.
