The well-tended garden does not suffer materially from inroads of insect pests especially in favorable seasons; cool, damp weather, and hot, muggy weather are conducive to fungoid diseases which sap the strength of the plants and make them less resistant to any kind of assaults, whether of insects or disease, but with normal weather and bright dry air a part of each day at least, little trouble should be experienced from insect pests; especially should this be the case if precautionary work has been done the previous fall in the way of gathering up and burning all rubbish that can harbor insects or disease and especially if the precaution is taken to fall plough the garden, leaving the soil in the rough furrow over winter. This is especially good practice when there has been trouble with209 insect pests, especially cutworms, root lice, tomato worms—the pupae of which winter in the ground and if turned up by the plough will be destroyed, radish and cabbage maggot and the like.
Even though the past season has been practically free from trouble of this sort the intelligent gardener will recognize the possibility of trouble and in time of peace will prepare for war by supplying himself with the more common and useful varieties of insecticides. It is not desirable that the list should include everything in the bug pharmacop?ia; a few standard remedies faithfully and intelligently used are far better than an embarrassing assortment that leaves one undecided as to which is best and often results in half-hearted use of first one and then the other, with lax intervals which give the enemy time to recuperate and multiply.
It is best in deciding upon the insecticides and fungicides to be used to have a clear classification in mind of the several kinds of insect to be exterminated as one form of poison may not be suited to all forms of insect life: for instance, insects210 which chew or eat the leaves of the plants to which they are addicted, as the potato beetle, caterpillar and the like, can most readily be destroyed by poison applied to the foliage; insects which do not eat the vegetation on the surface, but puncture it and drain away by suction the juices of the plant, like the aphis and other plant lice, will not be injured by surface poison, but must be destroyed by the contact of corrosive poison with their bodies, or with hot water, which is one of the best insecticides known, not only destroying all insect life with which it comes in contact, but cleansing and strengthening the plants. It should be used as a spray at about a hundred and forty degrees, taking pains to reach the underside of the leaves as well as the upper surface, and as it can be used when the fruit is in any stage of growth its advantage is obvious.
For the eating or chewing insects and beetles there are several reliable poisons on the market, all ready for use, needing only to be mixed with a definite bulk of water, flour or lime, according as the poison is to be used as a dust or a spray.
211
ARSENATE OF LEAD
Used for all chewing insects that attack foliage and fruit trees; will not wash off nor burn the foliage. Use two or three pounds to fifty gallons of water as a spray. Price about forty-five cents a pound.
ARSENATE OF ZINC
A quick-acting adhesive insecticide for potato bugs, rose beetles and vegetables that have not headed sufficiently to be injurious if touched with the poison. Forty-five cents per pound.
BUG DEATH
Used instead of Paris green for eating insects on potatoes, squashes, melons, eggplants, cucumbers. Twenty-five cents a pound; directions accompany it.
PARIS GREEN
For all chewing insects. As a dust use one part of the poison to one hundred parts plaster, or flour; as a spray, one pound Paris green to212 one hundred and fifty to three hundred gallons of water according to the tenderness of the foliage. Sixty-five cents per pound.
PYROX
For eating insects, fungus growth, blight and rot. Adheres to foliage. One pound to six gallons of water. Forty cents per pound.
SLUG SHOT
For potato bugs, tomato and cabbage worms, lice aphis and worms—use as dust with blow gun. Twenty cents a pound.
For fungoid diseases, blight and rot the various Bordeaux mixtures, single and combined with the arsenates so as to take the place of a separate poison for chewing insects, are suggested.
BORDEAUX MIXTURE
The standard remedy against fungus, rust and rot. Five ounces to one gallon of water is standard strength. Spray at intervals until fruits sets, for potatoes till danger of late blight is passed. Thirty-five cents a pound.
213
BORDEAUX-ARSENATE OF LEAD
A combined fungicide and insecticide for potatoes, melons, cucumbers and squash. Three ounces to one gallon of water. Spray once a week or every ten days. Forty cents per pound.
KEROSENE EMULSION
For all soft-bodied, sucking insects, especially aphis and lice. One pound of paste to ten gallons of water. Paste, thirty cents a pound.
Directions for Preparing
KEROSENE EMULSION
Dissolve one-half pound of soap in one gallon of boiling water, add two gallons of kerosene, and force through a spray pump again and............
