CODLIN MOTH CONTROL

SPRAYING NECESSARY TO ELIMINATE LOSSES SIMPLE MEASURES It is estimated that many hundreds of cases of apples and pears are destroyed each year in Hawke’s Bay by the fruit being infected with the grubs of the codlin moth, says “The Napier Daily Telegraph.” This pest is kept under control in the commercial orchards, and it can be similarly controlled in backyard and homestead orchards by giving the trees the necessary attention. Control measures are not complicated or difficult where spraying appliances are available, although a number of spray applications are essential. The grubs are prevented from entering the fruit by keeping the fruits covered with a poisonous substance, and as the fruit is rapidly expanding frequent applications of the poison are necessary. Arsenate of lead (powder) is universally used for this purpose, and a suitable strength is loz to 4gal. of water. The first spray should be applied when about one-half of the blossoms have dropped. The next two applications are best made at not more than fortnightly Intervals and thereafter at intervals of three weeks until early in February. This treatment, if thoroughly applied, will usually ensure fully 95 per cent of the fruits being free from grubs.
