Control Method 



LIME-SULPHUR applied thorough- 

 ly to twig-borer infested trees 

 just before the buds begin to open in the 

 spring, is known to be an effective 

 means of controling this pest. At this 

 time over-wintering larvae become act- 

 ive in their cells and are readily reached 

 by the contact spray. The later the 

 application is made before the buds 

 open, the better will be the results ob- 

 tained. By delaying the application of 

 lime-sulphur until the time mentioned a 

 single treatment will be effective in 

 controlling both San Jose scale and the 

 twig-borer. 



Success is sure but it must be empha- 

 sized that it depends on the proper tim- 

 ing of application, correct strength of 

 material and extreme care and thor- 

 oughness in the work done. One must 

 use standard lime-sulphur solution of 

 32 degree or 33 degree Baume test. The 

 proper dilution is at the rate of one 

 gallon of lime-sulphur to eight gallons 

 of water. It is important that every bit 

 of twig, branch and trunk surface be 

 covered. 



The addition of arsenate of lead to 

 the lime-sulphur solution has sometimes 

 been recommended for the control of 

 the peach and prune twig-borer but ex- 

 periments and observations made in 

 Idaho and other Northwestern states

show that this combination is unnec- 

 essary and creates needless expense. 

 Attempts to control the pest with arse- 

 nate of lead sprays alone are likely to 

 prove unsatisfactory. There are cases 

 where such a spray has gotten results 

 desired but repetitions of the same 

 method may end in failure. This is 

 probably due to the fact that borers 

 emerge so irregularly in the spring 

 that it is impossible to apply one 

 poison spray which will be effective 

 against all larvae coming out of their 

 winter quarters. 



Caring for the Tractor 



TAKING a tractor into the field that 

 has stood idle all winter without 

 any care or inspection is to invite 

 trouble. In calling attention to this 

 phase of the use of a tractor, Tractor 

 Farming has this to say: 



"Keeping a tractor in first-class 

 working order is not a difficult matter 

 for the average man if he knows how to 

 do it, provided of course, that he has 

 a machine which is designed with easy 

 accessibility in mind. 



"It is not at all difficult to tighten the 

 connecting rod or main bearings on a 

 properly designed tractor, and a man 

 of ordinary intelligence can do the job 

 with a little instruction. Neither is it 

 a difficult job to remove the carbon

from the combustion chambers, to grind 

 the valves, remove the spark plugs, re- 

 place worn rings, adjust the magneto, 

 breaker points, and numerous other lit- 

 tle jobs which require but a few min- 

 utes for an experienced man, but which 

 play a very important part in keeping 

 a tractor on the job without delays. 



"Time lost on account of trouble with 

 any farm machine is usually a strious 

 matter, as it nearly always interferes 

 with the planting or harvesting of the 

 crop and costs money. In the case of 

 the tractor, which is used for more oper- 

 ations and more days per year than 

 most other machines, it is even more im- 

 portant than with the rest of the equip- 

 ment. 



"With the large number of tractor 

 schools which have been held during 

 the past year and held by many state 

 colleges, there is no excuse for any trac- 

 tor owner not being capable of over- 

 hauling his own tractor. The instruc- 

 tions given in these schools is not only 

 of value to the operator while the ma- 

 chine is in the field but it also qualifies 

 the owner or operator to go over the 

 tractor at odd times in order to put 

 everything in shape.." 



Notwithstanding the advance in the 

 price of nursery stock it is still profit- 

 able to plant well selected varieties of 

 many of the tree fruits.
