4.  Rust is a disease the appears in Cereals
Crops i.e. Wheat
 It is caused by a fungus knows as
Puccinia spp (3,000-4,000) Species
 Puccinia is an obligate parasite
 Required two alternate host
 It has macrocyclic life cycle
 Common name of “Rust” in other languages
Are rati,gerua,tombora etc.

5. According to G.C Ainsworth (1971)
 Kingdom Fungi
 Division Eumycota
 Sub-Division Basidiomycotina
 Class teliomycetes
 Order Uredinales
 Family Puccinaceae
 Genus Puccinica
 Species P graminis tritici

6. There are three form of Rust Affect the wheat
as follows
 Stem rust
Puccinia graminis tritici (black Rust)
 Leaf rust
Puccinia rodentia (Brown Rust)
 Stripe rust
Puccinia striiformis (yellow Rust)

8.  Most destructive wheat disease Severe grain
shriveling
 Masses of pustules on leaves & stems
containing brick red spores
 Rust infested plants transpire much more
water than normal.
 Most important disease of wheat, globally!
 Drastically reduces growth and yield, up to
70%!.

10.  Fungus
Puccini graminis f. sp. tritici
 Common names:
1. stem rust
2. black rust
 Infects:
1. wheat
2. barley
3. Barberry

11.  Temprature
23-25 Centigrade
At this temperature large number of
teliospores are produced
 Host
Berberis
wheat

12.  Reddish brown pustules.
 Large number of uredo spores are released
 Brownish appearance even from distance.
 Towards end black telia are produced for this
reason it
 It is called black rust.
 The site of infection is visible symptom of
disease.

14.  It has two host as follows
 Primary Host (Triticum aestivum)
 It Produces i.e urediospores & teliospores
Basidiospores
 Secondary host (Berberis Vulgaris)
 it produces i.e aeciospores & pycnidospores

15.  Fungus gains entrance to host through stomata.
 Up to five spore Spore stages of Puccinia graminis
Stage 0:
Spermogonium. Produces spermatia and receptive
hyphae.
Stage I:
Aeciums produce aeciospores.
Stage II:
Uredium produce urediospores.
Stage III:
Telium produce teliospores.
Stage IV:
Basidium produceages.

19.  Variety choice.
 Fungicides.
 Cultural practices.
 Earlier wheat maturing varieties.

20.  That all about it !
