Abstract


Previous investigations in Victoria, Australia (Meagher and Rooney, 1966; Barry et at., 1974; Meagher and Brown, 1974) have shown that crop rotation can provide good control of the cereal cyst nematode (Heterodera avenae Woll.) with resultant increases in grain yield. This practice is not always feasible economically, especially on farms of limited size, and better control of the nematode may ultimately be achieved using resistant varieties (Brown and Meagher, 1970). In the meantime, however, the use of nematicides has been considered (Brown et at., 1970; Brown, 1972, 1973; Meagher et at., 1978). These studies have shown that a wide range of nematicides, fumigant, non-volatile, and sterilant, can provide excellent control of H. avenae. This paper reports further results on the control of H. avenae in wheat, using low rates of fumigant and non-volatile nematicides applied in the drill row at seeding.
