Banteng was resistant to net blotch
, barley stripe (Arabi, 2005b) and powdery mildew (Arabi and Jawhar, 2012), which could give it special interest in barley breeding programmes.
The main foliar fungal diseases are brown spot (Bipolaris sorokiniana (Sacc.) Shoemaker), net blotch
(Drechslera teres (Sacc.) Shoem.) and powdery mildew (Blumeria graminis DC.
A total of 86% of the 200 farmers surveyed by agri-business Sygenta pinpointed rhynchosporium, while 60% included net blotch
, 53% mildew and 42% rust in their lists of problems.
She also works on DNA markers for other traits, such as protein quality and resistance to leaf rust and tan spot in wheat and resistance to net blotch
and Septoria speckled leaf blotch in barley.
Genetics of seedling and adult plant resistance to net blotch
(Pyrenophora teres f.
was down on the average, whereas mildew was identified in 96pc of crops, yellow rusts in 32 pc and brown rust in 36pc.
Left untreated, net blotch
can cause yield losses of 30-40%, plus it can cause reductions in grain quality.

control is, however, becoming a challenge with the increase in resistance to strobilurin fungicides, but pyraclostrobin (Comet 200) continues to perform well in the field."
Stellar-ND is moderately susceptible to wheat stem rust pathotype Pgt-QCC, net blotch
(caused by Pyrenophora teres Dreschs.), and Barley yellow dwarf virus.
