You can prevent borer injury and a serious build-up in the population of 

 borers with sprays of parathion (2-100) or LPN-300 (l-l/h-lOO) , Malathion is not 

 nearly so effective and DDT iiTOuld favor an increase in mites. 



Spray thoroughly so as to cover all the bark of limbs j crotches and trunks 

 on all peach trees both young and old. 



Put on the first spray about June 25 and follow it up with two more at 3-week 

 intervals, 



APPLE growers are urged again to put their orchards on a 3-year rotation for 

 oil - more often does no harm, A thorough application of a superior type oil 

 once every 3 years can save you some future headaches. 



It is the best vray to knock out San Jose Scale, You are killing red mite in 

 an entirely different vray^ thus preventing or at least delaying the development 

 of resistant strains. TJaese are outstanding reasons j there are many other advant- 

 ages such as making sure the sprayer is all set to go. 



If you groTiT aphid-susceptible varieties such as Spy, Gravenstein, Baldwin, 

 Cortland, Greening or Red Delicious include some insurance against rosy aphid in 

 you plans. They did not cause much trouble in 19^6 and no one can predict accur- 

 ately -what will happen in 1957c We do know that 1956, throughout the summer and 

 fall T;hen the rosy aphid is on plantain, was very favorable to many other species 

 of aphids. 



If you grow BLUEBERRIES in sod and are troubled by Japanese beetles, grub- 

 proofing that sod v;ill at least keep them from breeding right there in your own 

 field, of course it won't stop them from breeding in other turf and flying in to 

 your berries. 



It tells how to grub-proof turf with heptachlor, dieldrin or chlordane and 

 how to protect fruit from beetles in the 1957 Blueberry Chart and in Extension 

 Leaflet #295. 



Perhaps you can get neighbors to grub-proof their essential turf vdth one of 

 the insecticides and then, to bring about an ultimate and permanent reduction in 

 the number of beetles, make sure that you or someone in the area put some milky 

 disease spore po-vvder on same turf that will never be treated vfith a chemical,
