After reregistration, a number of its uses were voluntarily restricted, and currently, it is used in nonfood areas to control flies, roaches, and ants among other pests. Outdoors it is used on ornamental plants, golf courses, and lawn grass to treat lepidopteran larvae pests, it is also used to treat flies in animal husbandry in areas that are ...
Some chemical defenses once thought to be produced by the plant have since been shown to be synthesized by endophytic fungi. The chemical basis of insect resistance in endophyte-plant defense mutualisms has been most extensively studied in the perennial ryegrass and three major classes of secondary metabolites are found: indole diterpenes, ergot alkaloids and peramine.
The fungus then begin to move down and invade the crowns and the roots of the plants. From far away, the turf appears yellow or blackish brown. The colors that appear on the turf directly reflect the nitrogen levels in the plant. When turfgrass has low levels of nitrogen it turns yellow and when it has high nitrogen levels, it turns blackish brown.
Ophiocordyceps sinensis (synonym Cordyceps sinensis), known colloquially as caterpillar fungus, is an entomopathogenic fungus (a fungus that grows on insects) in the family Ophiocordycipitaceae. It is mainly found in the meadows above 3,500 metres (11,500 ft) on the Tibetan Plateau in Tibet and the Himalayan regions of Bhutan , India , and Nepal .

When the fungus is ready to reproduce, its fruiting bodies grow from the ant's head and rupture, releasing the spores. This process takes 4–10 days. [9] Dead ants are found in areas termed "graveyards" which contain high densities of dead ants previously infected by the same fungus. [16]
Upon the death of the host, the O. unilateralis produces a stalk-like structure erupting from the head of the dead ant from which spores are released to the peripheral environment. [12] this process enables the fungi to infect more ants and, in the process, creates high densities of dead ants in the forest environment known as 'graveyards'. [12]
Snow mold is a type of fungus and a turf disease that damages or kills grass after snow melts, typically in late winter. [1] Its damage is usually concentrated in circles three to twelve inches in diameter, although yards may have many of these circles, sometimes to the point at which it becomes hard to differentiate between different circles.
