GRASS GRUB PEST

ELIMINATION BY IRRIGATION NORTH OTAGO GRASSLANDS STRICKEN The ravages of the grass grub as well as by other caterpillars and grubs were exemplified at the monthly meeting of the North Otago Farmers’ Union yesterday, when various members expressed concern at the condition of their paddocks, some stating that many places could hardly run a rabbit, much less sheep. In fact, it was_ stated by one farmer that the condition of the grasslands in and around Duntroon was definitely serious, due in his opinion, chiefly to the ravages of the grass grub. The dry season had helped to promote this pest, and the outlook for the soring was anything but bright. , Discussion arose as a result of a letter received by a member from Lincoln College bn the habits of grass grubs and caterpillars generally, stating that a great deal of damage resulted each year from the destructive nature of these pests, particularly to the grasslands of Canterbury. Mr A. C. Hurst, of _ Papakaio, pointed out that one effective method of counteracting the pest was by means of irrigation. In his opinion, irrigation, was the only effective way of eliminating the grub from pasture lands. He had tred it with considerable success. Irrigation brought the grubs to the surface, where the birds played havoc with the pest. It was the only practical way. The Redcliffs irrigation scheme had also proved that this method could be used to advantage. Another member favoured promoting bird life. Without the birds, farmers could do little with such pests as the grass grub. He urged the union to seek the services of the Cawthron Institute to investigate the matter. Others described how the birds could help in eliminating the pest, especially where irrigation had been carried out. Even after heavy rain the birds could be seen feasting upon the pest brought to the surface. “ I have never seen the paddocks in such a bad condition as at present,” said Mr J. B. Chapman. He remarked that the matter was becoming very serious and the prospect for the spring was anything but bright. He thought that the union should co-operate with the Department of Agriculture. It required the co-operation of all members. It was recognised by the members present that the position was quickly becoming serious, and it was decided to urge the Department of Agriculture to take steps, to eradicate the pest. An emergency committee was appointed to deal with the matter.
