APPLES - This yoar tho najor insect pests of apples have boon - or are now - 

 plum Curculio, Bud Moth, Red-banded Leafrollor, Codling Moth, European Rod Mite 

 (or in some areas the Clover Llite), Still to bo accounted for are late Red-banded 

 Leafrollor, sui:Tmer brood Bud Moth, second brood Codling Moth and Apple Maggot,

The prolonged period of emergence, feeding and egg laying by Pluin Curculio 

 make it outstanding at present in actual damage caused to fruit. Heavy rains washed 

 sprays off and it seemed almost impossible to maintain effective protection, 



Overv/intering Bud Moths were killed effectively by dormant applications of 

 DN materials. Many orchards, however, provide excellent demonstrations of the 

 necessity for complete coverage. They also point out the increased insect control 

 to be gained by pruning off those low-hanging branches v;hich are hard to hit 

 thoroughly. Control of the summer brood and the final damage to the fruit will 

 depend upon how well growers have applied sprays to the undersides of the foliage 

 during the latter part of July, i5|)plications of oil and nicotine in delayed dormant 

 or even the thorough underneath application of load arsenate and DDT in early sprays 

 were quite effective also. 



Red-banded Leafroller needs watching. Satisfactory control of this insect is 



impossible by ordinary spraying methods in trees v/hich aro not pruned, are full of 

 watersprouts or hang right doxvn into tho grass. It is not an easy insect to kill, 

 but all the evidence points tov/ards the use of DDT plus lead arsenate in one 



application , to the right place at tlie right time . The placo is the undersides of 



all the leaves and tho time is during tho last week of July and first two weeks in 

 August, Of course, the roal time was back at Calyx, 1st and End Cover periods. 



Codling Moth seems to be under control v;here protection with DDT was complete 

 throughout its rather extended active period. The first brood was late and v/e do 

 not knov; yet hov/ extensive the second brood may become, 



European Red Mite has caused a great deal of damage although I am sure some 

 growers with Red ilite injury do not realize it. It showed up first on Baldwins 

 and Delicious and then on other varieties. The picture is complicated by serious 

 outbreaks of Clover Mites in at least one area. The Two-Spotted Mite still has 

 time to come into thi; picture. 



With good oils available — and they v;ill be if growers demand them — it seems 

 unnecessary to endure the "run around" for svunmer Red Mite control I have witnessed 

 recently. At present summer control measures are expensive, likely to be injurious 

 and many times are ineffective. Let hindsight remind us, now, to use foresight in 

 1949 and to control the European Rod Mite early v;ith the proper applications of a 

 good oil, 



Apple Maggot fly emergence started late and reached a peak slowly. The 

 additional emphasis upon summer Bud Moth, Rod Mite and Red-banded Leafroller 

 control in late Julj;- and August should have helped also to control this pest,

Mpnthly Rodent Con trol Notes , Tho best time to prevent losses by 

 rodents in fam storages is just previous to the actual storing of 

 products. Controlling rats or mice after tho storage room is 

 filled is difficult and cxponsivo. (Carl Henry)
