 effective against mites^ aphids and pear psyllao 



In 19^3, Dru Philip Garinan of the Connecticut Agricultural Experiment Station 

 acted as coordinator of a cooperative project involving the testing of promisiig spray 

 mixtures. Mixtures vrere prepared at a central point and distributed to workers in 

 Connecticutj Massachusetts and Rhode Island, The equipment used to apply the mater- 

 ials ranged all the via.y from hand-operated, compressed-air sprayers to high powered 

 hydraulic or air-blast machines, A vri.de range of fruits viere included in the several 

 iiridoly separated tests, 



A mixture containing methoxychlor, malathion and captan gave best results in 

 all tests No injury to foliage or fruit had occurredo The degree of insect and 

 disease control obtained seemed almost too good to be true. 



In 19Sh) the same f onnulation vras tested further. Again under the supervision 

 of Dro Garman supplies of this and modified formulations were prepared and distributede 

 In addition to the general tests carried on against a Vv'ide variety of pests on a range 

 of fruits and fruit varieties in Connecticut, Rhode Island and Massachusetts, a number 

 of workers in Nevr York State pitted the newly developed formulations against specific 

 pests in their regular experimental procedures. 



Once again, the mixture of methoxychlor, malathion and captan proved its worth 

 against such pests as plum curculio, aphids, codling moth, apple scab, mites, black 

 rot of grapes, and others* 



Against some of the rust diseases and mildews it is perhaps a little weak but 

 at present this is not considered of sufficient importance to v/arrant a change in the 

 formulation. In 195U some leaf spotting and yellovdng did occur on Red Delicious and 

 Baldwin apples and on peaches* The fruit vras not damaged in any vray. It seemed that 

 most of the injury was caused by certain post-bloom applications and under certain 

 vreather conditions which prevailed at the time. In some cases, over-application may 

 have contributed. 



It appears that the advantages of the mixture when used aa intended far out- 

 v/eigh the disadvantages just mentioned. 



This general-purpose fruit spray mixture is not a substitute for thorough cover- 

 age; it is not magical in its performance, Neither is it a substitute for fairly 

 accurate timing of applications. To cover the range of pest activity on our many 

 fruits may require from as few as 2 or 3 applications during the season to as many as 

 9 or 10, Mo chemical or mixture of chemicals can be expected to protect fruit or 

 foliage against a particular pest unless applied properly and at such times as to pro- 

 vide protection vrtiile the pest organism is active. 



This is the history of NY-WE - a General-Purpose fruit spray. It will be avail- 

 able in 19^5 J as a mixture of its active ingredients, methoxychlor, malathion and 

 captan all ready to be dumped into the sprayer tank. Or, if preferred, each ingred- 

 ient may be purchased sepai^ately and mixed in the tank, l.'Tien this is done, one should 

 use from 2 to 3 pounds of 50f5 methoxychlor wettable powder, 2 pounds of 2$% malathion 

 wettable powder and f rom 2 to 3 pounds of a $0% captan vrettable pov;der in each 100 

 gallons, 



VJith thorough applications timed according to the schedules for the various 

 fruits set forth in Circular 178 of the Massachusetts Extension Service, I am sure you 

 will be happy with the results,
