 n...,hiy there is no other insect <, has done, and is still doing, more - ..ma,e in the orchards of Arkansas .sar S is the San Jose Scale. It is also -. m that this insect has been the .S,set of & great deal of discussion, =. M it remains a fact that there are ,.,,, ~. hundreds of acres of orchards .s.t M Ere being killed by this insect; .sSnsauds of dollars are lost annually s.c.rse of it and the majority of peo- s,s attu do not know what the insect | like.
 .h,ch spends the winter in the half .roxn stage beneath the tiny gray .c.Ias which may completely cover .h1 body of the tree. Soon after the .nr,pg opens and the weather be- .omes warm these insects which have ,,ssed the winter successfully reach the adult stage when thousands of .o,,nx ones are born. The young scales crawl about on the body of the tree for short time until they either narish or find g suitable location. If iayorably located the tiny beak or pro- hosis is inserted into the soft tissue of the tree and the scale begins to saed upon the sap of the tree. Scales never change their position after be. coming established, and shortly after establishing themselves a small scale hegihs to form over their bodies. It is balieyed that in the South there are four or i've broods every year. It usually requires only three or four years for the insect to kill a tree. Some may live longer, but do not bear profitable crops of fruit. Trees attacked by the insect usually make a very poor growth, the body turning m ashy gray color owing to the nu- merous insects which cover it and generally, especially in peach trees, the tops and tips of branches will die while vigorous young shoots will come out on the lower portion of the tree. If the tops are killed and these young sprouts appear there is still chance to make a useful tree. Cut of the dead portion and spray thoroughly with the lime sulphur solution. It is only question of few years until all states will be quarantined so that no fruit or fruit trees having scale can be shipped into them. Several states have such law now, but pos AlbU few of them are enforcing it. igeale is easy to controlxif, we only, go lfter it right. The solution must, Z however, be applied during the winter pr dormant season since it is strong though to do great damage to young leaves or fruit. If the best results lre to be obtainfd it is absolutely G. sential that the orchardist know the e1act strength of the solution and that 1t is strong enough. In order to Do able to avoid costly mistakes every orchardist must equip himself with a lime sulphur hydrometer which can be purchased for about a dollar. This instrument will en. ahle one to know the exact strength H the solution which he is using. Ths solution should test about 4.5 degrees at 2 temperature of 60 degrees F. vhen.ready to apply for scale.
