INSECT AND DISEASE PESTS 
Plant diseases are many kinds. Some, such as mildew, leafspot and rust attack leaves. Others, as fire blight, damage 
branches and stems of plants. Some, such as root rot, waylay the plant at the roots. Some diseases such as mosaic seem 
to disturb plant life processes in some way, no one is sure as to just how. These diseases are spread by various agencies 
as soil, wind, insects, contact, seed, tools, shoes of the gardener and also birds. 
Some of the better known ways of controlling various diseases, depending upon their characteristics, are by spraying, 
dusting, seed treatment, soil disinfection, rotation, planting on new and clean ground, breeding resistant strains and 
destroying infected portions or crop residues. 
INSECT PESTS 
Insects are of two general kinds, chewing and sucking. The first, such as leaf eating beetles, grasshoppers and cater¬ 
pillars, eat tissues or leaves and are controlled by a stomach poison applied to the plants. The most satisfactory poisons 
are lead arsenate, calcium arsenate or Paris Creen. 
Sucking insects pierce the leaves or other covering and suck the plant juices from within, so they must be killed by 
some contact poison which kills by its burning action, poisoning thru the breathing apparatus, or, by suffocation. Among 
these insects are thrips, aphids, scales and mealy bug. The chief contact sprays are nicotine sulphate, nicotine dust, 
pyrethrum powder, dusting sulphur, lime sulphur, oil emulsions, miscible oils or fish oil combinations. Non-poisonous 
sprays which kill both chewing and sucking insects are Evergreen, Red Arrow, Derrisol and Rotecide. 
For control of insects and plant diseases. Much the simplest procedure in the average sized garden, (ornamental or 
vegetable) is to go to your local dealer who specializes in garden supplies, buy the chemicals needed in prepared 
form under trade names and use according to the manufacturer’s directions. Be sure of course to read labels and 
directions on package before buying. Buy nationally advertised goods of known effectiveness when possible. Also arm 
yourself with printed literature.
