Parathion; Be Careful (use approved respirator): do not use in Schedule II; 



requires special safening materials (charcoal) on Liclntosh and related formsj 

 short protective period compared to methoxychlor and DDT; expect resistance 

 in mites after 3 to 1; years; repeated applications of low concentrations 

 favors development of resistant strains; best uses are: for Bud Iloth in pre- 

 bloom and mid to late July; for Red Mite and Yellow Liite in Pink, Calyx, and 

 2nd Cover or Calyx, 2nd and 3rd Cover, for young Red-banded Leafroller in Calyx; 

 virhen used in Pink through 2nd Cover other insecticides and miticides are 

 omitted but interval must be shortened to handle curculio; may be incompatible 

 vri-th phenyl mercury and captan fungicide . 



EFN ; Be Careful (slightly less hazardous than parathion) use approved respirator; 



do not use in Schedule II or on Mcintosh and its related varieties; not safened 

 by charcoal on these; on other varieties has same uses as parathion and with 

 longer residual effect against curculio and mites; poorer than parathion 

 against aphids and bud moth. 



TEPP : & Careful , requires special respirator: do not use in Schedule II; useful 

 against aphids in early prebloom fungicide application or in summer; effective 

 miticide in Pink, Calyx and 2nd Cover or Calyx, 2nd and 3rd Covers; results 

 variable in summer applications; no residue hazard; avoid combinations with 

 phenyl mercury; use maximum concentrations to delay development of resistance. 



Malathon ; a phosphate but hazard to user similar to DDT and TDE; extensive trials 

 of vrettable povfder are suggested in summer sprays for aphids and mites; 

 superior to parathion and TEPP against aphids; less effective against mites; 

 compatible with materials used at that time. 



88R (Aramite, Miagaranite, Orthomite, etc.) strictly a miticide; best used in summer 



under hot, dry conditions; at least 2 applications necessary for clean-up; 



non-hazardous for user; compatible and no injury complications; easy on 

 beneficial insects. 



K6U51 (Ovotran); for limited trial against mites in 3-U applications starting with 

 Calyx; use at rate of l/2 lb. of ^0% wettable powder per 100 gallons; an 

 excellent, non-hazardous miticide because it kills eggs as well as living 

 stages; safety en all varieties and compatibility with other materials not 

 yet fully understood; not suggested for mid or late summer applications nor at 

 higher concentrations; might be used as a substitute for oil in Schedule II. 



PMC (Dimite): a liquid, non-hazardous miticide suggested for limited trial in 



comparison vfith others listed; safety on various varieties and compatibility 

 not well 1.31 ovm.
