The organism has a short incubation period and as a result epidemics of bitter rot can develop rapidly. The presence of the disease is first indicated by the very small light brown sunken spots beneath the apple skin. [18] As the fungus grows and invades more of the apple tissue, the area becomes engorged until the entire apple is rotted. [19]

Puccinia asparagi is the causative agent of asparagus rust.It is an autoecious fungus, meaning that all stages of its life cycle – pycniospores, aeciospores, and teliospores – all develop upon the same host plant [1] [2] [3]. [4]
If a fungus is regularly exposed to fungicide meant to kill it — many fungi that can infect the human body also thrive in soil and decaying plant matter — it can develop resistance to it.
This is a list of fungicides. These are chemical compounds which have been registered as agricultural fungicides . The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [ 1 ]
Puccinia myrsiphylli is a rust fungus with the following characteristics: “Uredospores ellipsoid or sub-globose, pale yellow 30-40 x 26-30 μ; epispore hyaline, about 1.5 μ thick, closely and finely echinulate and with 4-5 scattered germ pores…Teleutospores oblong, cuneate or clavate, apex rounded, acuminate or truncate, usually attenuate at the base, usually gently constricted at the ...
It is presumed that this disrupts the binding of the fungicide to the protein, rendering the fungicide ineffective. Upregulation of target genes can also render the fungicide ineffective. This is seen in DMI-resistant strains of Venturia inaequalis. [10] Resistance to fungicides can also be developed by efficient efflux of the fungicide out of ...
Mancozeb is a dithiocarbamate non-systemic agricultural fungicide with multi-site, protective action on contact. It is a combination of two other dithiocarbamates: maneb and zineb. [1] The mixture controls many fungal diseases in a wide range of field crops, fruits, nuts, vegetables, and ornamentals. It is marketed as Penncozeb, Trimanoc ...
