Cereal cyst nematodes (CCNs) are plant parasites that significantly limit global cereal production. The most frequently reported pathogenic species are Heterodera avenae, H. filipjevi, and H. latipons. One of the most cost-effective, environmentally friendly, and easily adopted control measures is the use of genetic host resistance, which maintains nematode populations below the economic damage threshold level. Many effective sources of resistance to CCNs have been identified in cereals; however, their effectiveness and usefulness is dependent on the interaction of the specific putative resistant accession and the CCN pathotype found in a specific region. In this study, 719 wheat lines from …

The effects of Trichoderma harzianum, T. hamatum, T. viride, T. polysporum, and T. koningii on the wilt disease complex of chickpea caused by Fusarium oxysporum f. sp. ciceri and Rhizoctonia solani were investigated under field conditions during 2 consecutive years. Chickpea cultivar Avrodhi, grown in plots inoculated with F. oxysporum f. sp. ciceri and R. solani, showed chlorosis of leaves and wilting of foliage and exhibited a 22%-25% decrease in yield. Soil application of biocontrol agents (BCAs) checked the severity of wilt by 25%-56% and 39%-67% and increased the yield of chickpea by 12%-28% and 8%-24% in the 2 years, …
