Direct Chemical Action of Trichothecenes. Over a quarter of a century ago, Brian et al. (8) described the action of diacetoxyscirpenol on plants when 2.73 X 10" solutions of the metabolite inhibited stem growth and scorched leaves in two pea varities, lettuce, winter tares and other economic crops when applied exogenously. But carrot, beet root, mustard and wheat were not affected at the same application rate signalling genus and species specificity for the, metabolite. However, at rates that ranged from 1.37 x 10"... 

The fungus mainly attacks wheat though there are distinct forms that attack barley and oats. Initial primary foci may be found in early spring. From the pustules, spores are carried by the wind to infect healthy plants. During winter, spores are normally dormant on autumn-sown crops. Cool, humid conditions favour disease. Temperatures above 25 °C inhibit growth.
