Fewer eggs per egg-mass were recorded where Datura leaves were applied @25 g/kg soil. Candle-bra leaves, saw dust and Ak leaves each applied @ 25 g/kg soil significantly reduced the number of galls, egg-masses and eggs per egg-mass. Datura leaves @ 15 g/kg soil gave maximum plant height, number of leaves, fresh and dry weight of shoot while combination of amendments @ 3.75 g/kg soil significantly reduced the number of galls, egg masses and eggs per egg mass compared with uninoculated control.

VYAS; D.N. YADAV Abstract: Holotrichia consanguinea Blan., a major species of the root grub causes severe damage to summer crops in India. Biological control of the grub using micro organisms like Bacillus popilliae, Metarhizium anisopliae and Beauveria brongniartii have been tried by several workers in the last two decades. However, little effort has been made towards the control of grub using entomopathogenic nematode. In the present investigation, the effectiveness of Steinernema (= Neoplectana glaseri) was evaluated under laboratory and field conditions.

YASSIN; A.E. ISMAIL Abstract: Effect of nematicidal potential of Zinnia elegans Jacq., as a mix-crop along with tomato againstMeloidogyne incognita and Rotylenchulus reniformis was studied under greenhouse conditions. The final population of both nematodes and their rate of build up as well as the root gall index were significantly affected by the number of zinnia plants when grown together with tomato. There was a negative correlation between the number of zinnia seedlings and the final population of both nematodes. The lowest final population and rate of build up of nematodes were recorded at the highest number of zinnia plants (4 plants per pot). The highest root gall index (4) was found on roots of tomato grown alone, while the lowest (0.7) was found on roots of tomato grown with four plants of zinnia. This type of control is considered inexpensive and pollution free.

RAO; S.C. DHAWAN Abstract: Investigations on the emergence of juveniles (J2) from Heterodera avenae cysts during the absence of the host crop in natural conditions, revealed emergence from August onwards but not during May to July. The emergence of J2 gradually increased from August onwards coinciding with the decline in temperature in nature. When low temperature and moisture are available, then the emergence of J2 from the cysts occurred and such emergence of J2 during the off season, in the absence of the host roots, is detrimental and does not contribute to the population build up. The magnitude of suicidal emergence recorded was 31%, which might vary depending on the prevalence of low temperatures during the nights and occurrence of the rains durin August-October.
