growers keep very close ivatch of their susceptible varieties and make -use of the 

 regularly recommended sprays or dusts for apple maggot control plus emergency ap- 

 plications of methoxychlor closer to harvest. If organic materials such as DDT, 

 IDE and methoxychlor are depended upon entirely for apple maggot control, then it 

 is unsafe to stretch the interval between applications beyond 10 days, 



European Red Mite ; Oil used in Delayed Dormant (Dormant in the 

 captan schedule) is still very desirable for the control of this mitec If you 

 want to do a 100^ job, this oil application can be supplemented in Pink or in 1st 

 Cover or later ty some of the other miticides such as malathion or TEPP,^ Some 

 trials have been made with ovex (Ovotran, Orthotran, etct)» Results have been 

 excellent. Care must be taken, however, not to overspray and not to exceed the 

 recomraended dosages of l/k lb, of $0% ovex in Pink and If! t Cover and l/2 lb, per 

 100 in any later application. 



If no oil is used, then it is very desirable to plan a mite control program 

 using one of the foliage type miticides such as malathion, TEPP or for extensive 

 trial, the ovex mentioned above. Such programs are well outlined in the 19^5 Spray 

 Chart, 



TtTO-Spotted Mite ? This mite continues to be a problem in orchards 

 on the schedule making full use of organic insecticides. It appears relatively 

 late as compared to red mite and thus is not well controlled with the applications 

 put on during the early part of the seasono There is some indication that the full 

 ovex program of four sprays such as Pink, 1st Cover, 3-d Cover and ^th Cover, may 

 also handle two-spctted mite, I am of the opinion that the amount of ovex applied 

 to the ground cover during the process of spraying the trees might have a great 

 deal of influence upon the effectiveness of this program against the 2-spot, 



If two-spotted mite does develop and aphids are not a problem vinder hot; dry 

 conditions, Aramite is one of the most effective materials that can be used. If 

 aphids are also a problem one of the phosphates such as malathion would be more 

 logical, 



Demeto n (Systox, etcc)» This newer phosphate which is described 

 more fully elsewhere in this report, is worthy of limi ted trial on bearing trees. 

 Its compatibility with other materials that may have been used earlier or vfill be 

 used along with it, is not well known. This is a good reason for limited trials . 

 For the control of red mite, two-spotted mite and green aphid, demeton may be tried 

 in a single application used late in June or early July at a rate equal to 6-8 

 ounces per 100 gallons. On young or non-bearing trees, there should be no need 

 for hesitation in the use of demeton to control green aphid or mitese Ei+her BHC 

 or lindane could be used on non-bearjjig trees and might prove more economical and 

 certainly a lot less hazardous to those applying the material, Demeton must be 

 handled TJith the same safety precautions necessary with parathion . 



Residue Tolerances ; For many of our commonly used pees tic ides 

 definite residue tolerances on harvested crops have been or are being established 

 nan ty the Federal Department of Health, Education and Vvelfare, Eventually, it 

 will be unlawful for new pesticidesto be sold vmtil a residue tolerance on harvest 

 crops has been established for the material wiien used for the proposed purpose. 



It is important for all growers to understand the significance of t his amend- 

 ment to the Federal Food, Drug and Cosmetic Act, It is even more important for 

 growers to use pesticides in a manner which provides a high degree of pest control 

 while at the same time assuring crops at harvest time free from residues in excess
