The following notes re extinction of grass grub taken from tbe Lands and Survey Department's report on State nurseries and plantations may be of interest to our readers :— "In accordance with intentions outlined in last report, special provision was made to combat; the destructive grass grubs. Tbo almost continuous j wet condition of the surface, bowtver, I forbade our complete adherence to the proposed scneme, although through the" efforts directed considerably less destruction amongst the seedlings has eventuated this yea; than in the previous one. At Tapanui the yearlings, which have hitherto given us tbe greatest cause for anxiety, almost escaped injury, although the lined-out trees bave again suffered, but in a lesser degree. Soil-fumigalion with aptheric and vapourite was extensively carried out, over sowt. of these compounds being used in the operation. In addition, 5 tons of gas lime and 2 tons of kainit were also n.rmj:su-to areas overwbich tbe larvae were numerous ; but blocks so trfc*,ted require to remain fallow for at J from 9 to 12 months, during which time the discs and cultivator should be freely used. The most nifficulfc problem to fece, then, in affected localities is the eradication of tbe pest over the lining out areas, and, a/ter conducting a seri'e3 of experiments, no better means of accomplishing this end can be advanced than judiciously applying gas lime or epterite ts render the soil ob noxious to the beetles, and subsequent frequent cultivation when the ground is in a sufficiently arid state that no consolidation of tbe surface will acceue from the necessary trampling by horses Several tests with apterite, vapourite, permanganate of potash, etc, to demonsiratd tbe possibility of killing out right the grub 3, with an application of a reasonable quantity of the compounds, ended disappointingly, and, in my opinioD, tha asphyxiation of beetles or grubs cannot be accomplished with the mentioned fumigator3 at a price otherwise than prohibitive According to the Biologist to the Department of Agriculture, three species of grass grubs are in evidence at Ttis&nm—Odontria zealandica, 0. xaniliosticta, 0. sandageri —and this fact explains the lengthened of flights by the beetles. An excellent dry summer has permitted the desired intensecultivation work to be carried on, and tbe trouble from the pest will more than likely be lessened during the ensuing season.
