4:0% Nicotine sulfate is very effective for combating Apple Red 

 Bug and Apple j^hids. One pint in 100 gallons (1-800) is usually sufficient, 

 and it is compatible v/ith all other recomnended materials, Vs'hen used alone, 

 nicotine sulfate should be fortified with 2 to 4 pounds of dissolved soap 

 or soap flakes but in combination with other insecticides or fungicides 

 the soap is unnecessary and may be harmful. For combating Leafhopper, DDT 

 may be substituted for nicotine. 



DDT is both a stomach poison and a contact insecticide which 

 retains a toxic residue for 10 to 20 days. The preferred form for orchard 

 use is wettable powder containing 20% to 50/b DDT (most brands are novf 60%)» 

 Less is known about the effectiveness and compatibility of the emulsible < 

 concentrate. The standard formula is 2 pounds bO% wettable powder or 4 pounds 

 25jb wettable powder (both equal 1 pound actual DDT). DDT is recommended 

 in: 2nd Cover - to control Codling Moth (first brood,)' and in tho 4th 

 Cover - to cintrol Codling ^Moth and Leafhopper (both second brood) especially 

 on varieties harvested later than ilclntosh. Experiments indicate that 2 

 pounds bOfo DDT and 2 pounds lead arsenate are more effective than 4 pounds 

 lead arsenate in all post blossom sprays, and the combination is suggested 

 where .any of the insect pests are abnormally abundant, DDT is compatible 

 with all materials except lime. It should not be used in pre-blossora 

 applications because of possible harmful effect on pollinating insects. 



Dinitro compounds (summsr) such as Di'J-111, used at the rate of 3/4 

 to 1 pound or as advised by the manufacturer, is effective for summer Red 

 Mite control. Dusts such as DI\rD4, are also effective. Both sprays and 

 dusts are compa"cible with lead arsenate, DDT, wettable sulfur, and Fermate 

 and may be used safely after the 1st Cover when temperature is belov; gO'"^ F., 

 or below 80° F. if combined with sulfur. For prevention, this material may 

 be added to the 2nd Cover spray or it may be applied separately v;hen a Red 

 Mite infestation threatens.
