Plant pathologists offer soybean rust identification and management tips
...h soybean rust will have raised pustules with rust spores
inside. As rust severity increases, premature defoliation and early maturation of plants is common. Soybean rust can go from a few pustules in a field to full field defoliation in a matter of about two weeks. The main method of controlling soybean ru...

from a strain of anthrax producing only the capsule. In the group that had received the capsule vaccine, 7 of 12 mice survived challenge. In the control group, which received injections of a placebo instead of the capsule vaccine, none of the 12 mice...
