State Entomologist Merrill
 Tells How to Fight the Coddling Moth This Season
(By A. w. MorrillJ

Commission, the State Entomologst and the district inspectors endeavored to encourage the fruit growing iudus. try Of the state by furnishing intor- nation and advice necessary for the control of the codling moth in tbel infested sections The law as it ex. isted at the time was quoted and every eort made as far as our re- sources would permit to put the con trol of the cooling moth on business basis. As in other western states where such attempts hae been made there was little or no progress. The amended law which became effectio August 10, 1912, carried a provision giving power tc the Commission of Agriculture and Horticulture to stop the sale of wormy fruit. The enforce ment of such a provision has been found to be the key to codling moth control in other western states and there Is every reason to be confident that it will open the door to prosper. our fruit growing in codlng moth in. tested sections of this state
 This season as last. while the State Entomc logist's Office and crop pest inspectors are ready and willing to give advice. information and all possible assistance to work. the sal vation of the fruit crop rests with the growers themselves. Again as last year the fruit grower is advised to make proper preparations for the work of controlling the codling moth.
 There are few states in the entire country where there is a more favor able combination of producing and selling conditions for apples and pears, as we'll AS other fruits. Thor. ough conscientious eorts to keep the codiing moth and other pests under tUEi.oi will giye abundant returns.

 The first suggestion -c.ean up the orchards-should need no explanation as to what is meant The cleaning up pIoce should extend not only throughout every square foot of the orchard itself but to the middle Of the read. where the CrchaI adjoins the public highway.
 In regard to removing trees where too closely set it Is advisable 10 al. low 90 feet between rows of apple trees and 20 feet between rows of pear trees. en many Of the old or chards the trees are so closely planted that every alternate rCw should be removed T'ifty apple trees to the acre will give letter money returns than | 75 or 100.

Mod crate Summer pruning at the right time and the avoidance of too much | irrigating water should be depended on to direct the proper growth ci trees. Oyergrown fruit trees need severe heading back and perhaps the 1 best rule to follow for such work Is to prune when the saw Is sharpest ! regardless of, consequences to the fruit crop. Judicicus root pruning in association with severe heading back will tend to check the tendency to excessive wood growth. For more specific advice concerning pruning fruit growers are advised to consult the horticultural department cf the ' University Of Arizona. in connection with pruning it is advisable to scrape the loose bark from the tree trunks and crush the Alternating c0dllne worms that may be found in the co
