Example text

Genetic resistance is considered the most desirable control method since it is more cost effective and environment friendly than the use of chemicals. In this chapter we review developments in integrated management of insect pests, of parasitic broomrape plants, of the main disease-causing fungi, and of root-lesion and stem nematodes on chickpea. 2. ) is the third most important cool season grain legume in the world. Its seed are important source of proteins to human and animals. Low yield of chickpea attributed to its susceptibility to several fungal, bacterial, and viral diseases.

Trichoderma spp. and Pseudomonas fluorescens are important biocontrol agents of plant pathogenic fungi (Papavizas, 1985). The antagonistic activity of Trichoderma harzianum has been reported against BGM on chickpea foliage in controlled environments (Mukherjee & Haware, 1993). Spray of Trichoderma viride (107-8 spores/ml of water) managed the BGM on chickpea and increased the grain yield (Chaurasia & Joshi, 2000/2001). Currently, biological control of this soil and seed-borne plant pathogenic fungi has been addressed using bacterial and fungal antagonists.
