THE DEVELOPMENT OF RESISTANT PASTURE AND METHODS OF PASTURE MANAGEMENT FOR GRASS GRUB CONTROL

Abstract

Studies of the plant-insect relationship of grass grub larvae have highlighted the sensitivity of this insect to changes in the botanical composition of existing pastures, the effect of resistant plants sown as pure species or in mixtures wtih susceptible species, and the intensity of defoliation through the summer months. From these findings it is concluded that agronomic practices offer considerable scope as a component of a pest management programme for grass grub control.
