English Abstract

In vitro bioassay revealed that spore suspension of Bio-cont-T Trichoderma harzianum (19×106 spores / ml) caused mortality to 2nd stage juveniles of wheat seed gall nematode Anguina tritici by 53.9%.

Application of T.

harzianum for controlling A.tritici under field condition caused significant improvement in some growth and yield criteria of infected wheat plants such as harvest index, seed weight and number of seeds by 30.57, 31.6 and 28.7% respectively.

Soil and foliar fertilizing with urea and compound fertilizer respectively caused significant increasing in harvest index, seed galls weight, spike length, hay weight and number of seeds with non-significant reduction in the disease occurrence.

Grazing of wheat seedlings caused significant reduction in the infection criteria with disappearing of seed galls on wheat plants in some treatments particularly at planting date 15/ Dec./ 2010, grazing also improved growth and their yield criteria.
