INCORPORATION OF GRANULAR NEMATICIDES IN SOIL TO CONTROL PEA CYST-NEMATODE, HETERODERA-GOETTINGIANA

Experiments at four sites in England compared control of pea cyst‐nematode, Heterodera goettingiana, on peas, Pisum sativum, obtained when 10% granules of aldicarb or oxamyl were applied to the soil in different ways. The nematode was controlled best when the granules were incorporated in the soil by rotary cultivation (L‐bladed rotavator). The granules were incorporated too shallowly by rotary harrowing (Lely Roterra); applying granules in the seed furrows during sowing, or broadcasting them at the sowing depth of 5 cm, was only effective in 1975 when heavy and prolonged rain followed sowing.
