 1355033 Biological Control Three weeks after yellow starthistle was inoculated with rust spores, ARS plant pathologist Bill Bruckart (left) and California Department of Food and Agriculture plant pathologist Dale Woods inspect one of 20 test sites to learn about the pathogen's performance. Stephen Ausmus |
 1355034 Biological Control California Department of Food and Agriculture lab assistant Viola Popescu uses a cyclone spore collector developed at the Fort Detrick lab to harvest inoculum from plants at the CDFA greenhouse in Sacramento. Stephen Ausmus |
 1355035 Biological Control Small, rust-colored spots on starthistle leaves. The presence of these spots indicates that the first field releases of rust spores on starthistle are a success. Stephen Ausmus |
 1355036 Biological Control Morning dew on a yellow starthistle leaf. Evening inoculations with rust spores (from Puccinia jaceae var. solstitialis) are made to catch the overnight dew needed for spore germination and infection. Stephen Ausmus |
