London Purple. This is an active arsenical poison, which is very 

 highly recommended by American authorities as a powerful insecticide 

 against various plagues ; it is a by-product in the manufacture of dyes. It 

 should be mixed at the rate of of 1 Ib. to 200 gallons of water. Being 

 a powerful poison, it must be used with care, and only while the fruit 

 is very small or after it is gathered. Said to be one of the best remedies 

 for the Codlin Moth and similar insects. 



Paris Green (Arsenite of Copper). Another very active arsenical 

 poison, which is strongly recommended by American entomologists. 

 It may be prepared in the same way as London Purple, and used for 

 similar purposes. As the powder does not dissolve, it must be kept 

 well stirred while being used. It is an excellent insecticide for all 

 classes of leaf and fruit-eating insects. Paris Green may also be used 

 effectively in a dry state when mixed with wood ashes, lime or flour, 

 and dusted over the affected parts. 



Pyrethrum, The powder obtained from the flowers of two species 

 of Pyrethrum has long been known as possessing powerful properties as 

 an insecticide, and is largely used for dressing animals under the name of 

 " insect powder." It is very effective with Aphides and other small 

 insects, but it is too costly to be generally used. In using, sprinkle the 

 powder over the affected plants by a dredger or the sulphur-bellows. It 

 may also be used as a liquid in the proportion of one ounce ot powder 

 to two gallons of cold water. Apply as a spray, and as the material 

 is not poisonous may be used safely when fruit is advanced in 

 growth. 



Quassia. This gives a very bitter solution that is useful in keeping 

 down the various species of Aphides and preventing their coming. 

 Boil lib. of quassia chips in 3 gallons of water for two hours. Apply 

 as a fine spray. 



Resin Compound. This is formed by dissolving lib. of caustic soda 

 in a gallon of boiling water. Take away half the mixture, then add 

 81bs. of resin slowly to the remainder, keeping the whole boiling, and 

 stirring rapidly. When thoroughly dissolved, slowly add that portion 

 that was held back. Dilute with sufficient water till it will pass readily 

 through a thin cloth. Before using increase the bulk to 30 gallons by 

 the addition of water. Use with a fine syringe or spray. This is 

 considered to be an excellent remedy for the Scale insects. Two ounces 

 of London Purple added is said to make the compound still more 

 effective. 



Salt. This material may be used in moderate quantities to keep 

 down Slugs, Snails and Caterpillars, by sprinkling it overground infested 

 by these pests. Care must, however, be taken not to use it too freely, 

 as though in moderate quantities it is beneficial to most soils, yet an 

 excess may produce very injurious effects. 



Soap. In various forms soap is very useful as an insecticide, and 

 either the common or soft soap makes an excellent wash for trees, when 

 diluted in hot water. They are also very serviceable when used in 

 combination with kerosene, sulphur and other things. 



Soot. This is useful as a substitute for lime when dusted over plants,
