Pests; Fungal diseases of plants; Insect pests. 60 Vict. Provincial Board of Horticulture. 13 Prom the life history just given, three important facts are c)btained; (1.) It will pay to make a preventive application of some of the mixtures mentioned further on, with apparatus ^ before described, to all plum trees in the neighbourhood of hop yards, either Remedies. in the spring, before tlie appearance of the first >vinged generation and its consequent migration to hop, or in the fall after hop picking and after the lice have once more returned to the plum, and are making their preparations for the laying of winter eggs. The latter time will, perhaps, be preferable, for the reason that in the fall the plum trees will be less susceptible to the action of the washes, and a stronger solution can be applied without danger to the trees. (2.) All wild plum trees in the woods through a hop- growing country should be destroyed. (3.) The hop vines should be either burned or thoroughly drenched with kerosene emulsion as soon after the crop is harvested as possible, with a view of killing the males, and thus preventing the impregnation of the females. (4.) If the above measures have bef!n neglected and the lice have attacked the vines, the crop can still be pro- tected by spraying with insecticide mixtures, which, if thoroughly applied will prove effective, and there will be no danger of reinfestation from neighbouring untreated yards, since during the summer the lice cannot migrate except by crawling from one yard to another. Mr. Chas. Whitehead, , etc., Agricultural Adviser to the Privy Council, says in reference to the formula given below: " There are no actual proofs that any other remedy or tr«atment than washing is at all effectual against the aphis blight. Lime has been thrown up over the plants wi
