Laboratory life table studies on the blackfaced leafhopper (Homoptera; Cicadellidae) on Johnsongrass
The negative electivity indices for seeds and/or foliage of Johnsongrass
Sphacelotheca holci, as it's called scientifically, is a natural fungus that attacks johnsongrass
, a perennial weed that plagues many crops.
Among the grass and sedge weeds that Plateau controls are large crabgrass, rhizome and seedling Johnsongrass
, sandbur, yellow and purple nutsedge and broadleaf signalgrass.
Although our data did not permit us to relate territories to grass patchiness spatially, overall we did not notice obvious patterns in territory settlement; there were two possible exceptions: (1) the only two blackbird territories in the Plowboy Bend redtop block were very close to blackbird territories on the adjoining no redtop block, from which forbs, shrubs, and Johnsongrass
had spread into the redtop block (MAF pers.

(Sorghum halepense) leaves morphology, histochemistry and function.
Lepus alleni was rarely encountered in thick, matted stands of Johnsongrass
(Sorghum halepense) or tangled thickets of mesquites and other thorny plants such as lotewood and pricklypear.

Derigo is effective against more than 30 species of undesirable grasses, including johnsongrass
, vaseygrass, marestail, dogfennel and giant foxtail, as well as more than 100 broadleaf weeds.
Seeds of Malva neglecta, barnyard grass (Echinochloa crus-galli) and Johnsongrass
(Sorghum halepense) have been provided on natural gene bank of the Research Institute of Forests and Rangelands, Karaj Seed and Plant Centre.
For example, species such as johnsongrass

The dining table featured a series of centerpieces composed of umbrella palms, Johnsongrass
, zinnias, Billy balls, split-leaf philodendron, and onion blooms from Joe's herb garden, along with rough pieces of Arkansas fieldstone.
