Review of Integrated Management of Cereal Cyst Nematode Heterodera avenae on Wheat Crop under Centre Pivot Irrigation System

Cereal Cyst Nematode (CCN), Heterodera avenae, was reported on wheat crops grown under center pivot irrigation systems in different parts of Saudi Arabia, including Gassim, Al-Kharj, Hael and Tabuk. The estimation of wheat yield reduction by the CCN in Saudi Arabia ranged from 40 – 92% on sandy soil. An integrated cereal cyst nematode management plan was implemented at TADCO, Saudi Arabia, during the period 2006 – 2011, and it demonstrated a great degree of success as it minimized the expansion of infested areas with CCN and minimized yield reduction to around 4.1%. CCN management plan included monitoring CCN infestations on a yearly basis, and the application of granular systemic nematicide on the infested spots of each pivot. Also, the application of granular NPK 14-38-10 and granular K2SO4 fertilizers, implementation of crop rotation mainly alfalfa by direct drilling using the No-Till method for wheat sowing, use of certified wheat seeds and Machinery Sanitation.
