Some major diseases and pests of rice, maize, groundnut, soybean and
mungbean are discussed. Among the diseases, Helminthosporium maydis in maize
and Cercospora spp. in groundnut, soybean and mungbean were prevalent. Some of
the important pests were stem borers caused by Chilotraea polychrysa and
Tryporyza incertulas in rice, Ostrinia salientalis in maize, pod borers caused
by Etiella zinckenella in mungbean and leaf rollers caused by Lamprosema
diemenalis in groundnut. LAS]

Twenty-three insect pests and seven diseases have been recorded on the
mungbean in West Maiaysia. The beanfly, Ophiomyia phaseoli Tryon, and the pod
borer, Maruca testulalis Geyer, are among the most destructive pests. The two
most important diseases are leaf spot, Cercospora canescens Ellis & Martin, and
leaf blight, Rhizoctonia solani Kuhn (=Thanatephorus cucumeris (Fr) Donk). VC
1163-2-2-b-2B, one of the top yielders, is among 18 accessions identified as
resistant to Cercospora leaf spot. Apart from fungus disease two virus
infections have also been noted. [AS]

The mungbean germplasm collection increased by 59 samples to 4986 in 1979.
Mean yield of all cultivars over the 3 years were 1.81, 1.23 and 1.07 t/ha for
summer, spring and autumn, respectively. Five breeding lines proved highly
resistant to powdery mildew or Cercospora leaf spot or both. All 287 accessions
and 89 breeding lines were tested for resistance to the root-knot nematode,
Meloidogyne incognita. V 1133, V 2744 and V 2179 proved to be resistant in two
screening trials. The resistance mechanism in mungbean against powdery mildew
is affected by daylength. This disease is more serious under short-day
conditions. Inheritance study on leaflet number showed that this character is
controlled by a single complete recessive gene. Also, purple hypocotyl color
proved to be dominant over green, lobed leaf-shape over entire, black pod color
over tan, and green seed-coat over yellow. The best beanfly control and highest
yields were obtained by spraying omethoate at 0.5 kg a.i./ha at 3, 10, 17, 24
and 31 days after emergence. V 2184 was intercropped with each of 59 different
crops in the autumn trials. Intercropping significantly reduced beanfly
infestation of mungbean. [PLHJ
